C O N T E N T S

In the contribution ‘Tension in the industry’ (p.5) we take a close look at the ‘electrical’ landscape. We read that a number of factors such as new legislation, supply dependency and rising energy costs play a role in the decision of companies to carry out energy studies, to draft energy plans and to build energy plants. But this political-economic motivation can also count: in 2012, the EU spent twice the GDP of Belgium on the import of energy products. Furthermore, we are having to contend with outdated infrastructure. Investments in production and distribution are emerging while Agoria recently announced that investments in this sector have already been in a downward trend for a few years.

Let's also look at heat. In the whole energy debate we rather tend to focus on electricity, while most of our energy consumption consists of heat. In the industry there is a lot of waste heat available that is not valorised. On the contrary, it costs us energy and cooling water to dispose of this unused heat.

Many companies have realized some nice efficiency increases after two rounds of Benchmarking and Audit Covenant (see also the contribution on p.23). For example, through valorisation or the avoidance of

residual heat. Saving even more within ones own perimeter seems harder and harder. The logical next step is to work together beyond the boundaries of units and companies: between production plants, mutually between companies, and between companies and tertiary and domestic heat consumers.

In this 'cross-border' joining of forces there is also a major technical challenge. The providers of residual heat must maintain sufficient flexibility, the buyers must have sufficient guarantees on availability, the energy recovery must be maximum in order to provide sufficient ‘paying power’ and ecological return. To make all of this possible, we need to have a well thought out basic infrastructure and an intelligent scheme. Grontmij has already been realizing such heat networks in trendsetting European countries for years. Belgium also seems to be waking up (see the contribution ‘Heat networks also on the rise with us’ p.8).

Heat networks come at a price. But for several decades we’ve been providing our communities and industry with a basic infrastructure for clean energy and a local valorisation of a waste product. Worthwhile, right?

Smart electrical networks have a similar function. We are faced with lower availability of traditional production, increased consumption of electricity for heat pumps and transportation and a further penetration of decentralized, fluctuating renewable energy.

The challenges are keeping supply and reliability up to standard. The smart grids will help us to keep costs under control. Grontmij is also engaged in this subject matter: with Alexander Daenen as a member of the Board of Directors of Smart Grids Flanders, supporting and initiating activities on smart grids and providing speakers at study days and seminars, such as a study day on energy producing companies of Smart Grids Flanders (18 September this year), the Smart Grid School (8 October this year) and the seminar on heat networks of Smart Grids Flanders (25 November).

The evolution towards smart energy networks for heat and electricity is fully deployed!

V I E W P O I N T

In de bijdrage ‘Spanning in de industrie’ (p.5) nemen we het ‘elektrische’ landschap onder de loep. We lezen er dat een aantal factoren zoals nieuwe wetgeving, bevoorradingsafhankelijkheid en stijgende energie-kosten meespelen in de keuze van bedrijven om energiestudies te laten uitvoeren, energiebeleids-plannen op te stellen en energiecentrales te bouwen. Maar ook deze politiek-economische motivatie kan tellen: in 2012 heeft de EU tweemaal het BNP van België besteed aan de import van energieproducten. We hebben bovendien te kampen met verouderde infrastructuur. Investeringen voor productie en distributie dringen zich op terwijl Agoria onlangs bekend maakte dat de investeringen in deze sector al een paar jaar in een dalende lijn zitten.

Laten we ook eens naar warmte kijken. In het hele energiedebat focussen we nogal op elektriciteit, terwijl het grootste deel van ons energieverbruik uit warmte bestaat. In de industrie is er heel veel restwarmte beschikbaar die niet gevaloriseerd wordt. Integendeel, het kost ons energie en koelwater om deze warmte onbenut af te voeren.

Heel wat bedrijven hebben na twee ronden Benchmarking- en Auditconvenant mooie efficiëntie-

verhogingen gerealiseerd (zie ook de bijdrage over de Energiebeleidsovereenkomst op p.23). Bijvoorbeeld door valorisatie of het vermijden van restwarmte. Nog meer besparen binnen de eigen perimeter lijkt moeilijker en moeilijker. De logische volgende stap is over de grenzen van units en bedrijven samenwerken: tussen productie-installaties, tussen bedrijven onderling, en tussen bedrijven en tertiaire en huishoudelijke warmteafnemers.

In deze ‘grensoverschrijdende’ bundeling van krachten ligt ook een grote technische uitdaging. De aanbieders van restwarmte moeten voldoende flexibiliteit behouden, de afnemers voldoende garanties op beschikbaarheid, de energierecuperatie moet maximaal zijn om voldoende ‘paying power’ en ecologische return te voorzien. Om dit allemaal mogelijk te maken, hebben we een goed doordachte basisinfrastructuur en een intelligente regeling nodig. Grontmij realiseert al jarenlang dergelijke warmte-netten in trendsettende Europese landen. België lijkt nu ook te ontwaken (zie bijdrage ‘Warmtenetten nu ook bij ons in opmars op p.8).

Aan warmtenetten hangt een prijskaartje. Maar we voorzien onze gemeenschap en industrie voor

meerdere decennia van een basisinfrastructuur voor propere energie en een lokale valorisatie van een restproduct. De moeite waard, toch?

Slimme elektrische netten hebben een gelijkaardige functie. We kampen met lagere beschikbaarheid van traditionele productie, een verhoogd verbruik van elektriciteit voor warmtepompen en transport en een verdere penetratie van decentrale, variabele hernieuwbare energie.

Uitdagingen zijn het op peil houden van leverings-zekerheid en betrouwbaarheid. De smart grids zullen ons helpen om de kosten onder controle te houden. Ook in deze thematiek is Grontmij geëngageerd: met Alexander Daenen als lid van de Raad van Bestuur van Smart Grids Flanders, het ondersteunen en initiëren van activiteiten over smart grids en het leveren van sprekers op studiedagen en seminars zoals een studiedag over energieproducerende bedrijven van Smart Grids Flanders (18 september jongstleden) de Smart Grid School (8 oktober jongstleden) en het seminar over warmtenetten van Smart Grids Flanders (25 november).

De evolutie naar slimme energienetten voor warmte en elektriciteit is volop ingezet!

Patrick Van de VeldeBusiness Line Director Industry, Water & Energy Services

Ons energielandschap evolueert dag na dag. Zeker is dat we de komende 10 jaar met grotere uitdagingen en veranderingen te maken krijgen dan de voorbije 100 jaar!

Dans l’article ‘Tension dans l’industrie’ (p.5), nous allons examiner en détails le paysage ‘électrique’. Nous pouvons y lire qu’un certain nombre de facteurs tels que la nouvelle législation, la dépendance en matière d’approvisionnement et les coûts énergétiques de plus en plus élevés jouent un rôle dans le choix des entreprises de réaliser des études énergétiques, des plans énergétiques et de construire des centrales énergétiques. Mais on peut aussi compter sur la motivation politico-économique : en 2012, l’UE a consacré un montant égal à deux fois le PNB de la Belgique à l’importation de produits énergétiques. Nous avons également à faire à une infrastructure désuète. Les investissements pour la production et la distribution s’imposent, Agoria a d’ailleurs récemment communiqué que les investissements dans ce secteur sont en diminution depuis quelques années.

Tournons-nous à présent vers la chaleur. Lors du débat en matière d’énergie, nous nous focalisons principalement sur l’électricité, alors que la plus grande partie de notre consommation en énergie se compose de chaleur. Dans le domaine de l’industrie, il y a pas mal de chaleur résiduelle de disponible qui n’est pas revalorisée. Au contraire, cela coûte en énergie et en eau de refroidissement pour évacuer ces chaleur inutilisée.

Un certain nombre d’entreprises ont déjà réalisé de belles améliorations en matière d’augmentation

de l’efficacité après avoir participé à deux tours de Benchmarking et d’Auditconvenant (voir aussi l’article concernant la Convention Energétique à la p.23). Par exemple, en valorisant ou en évitant les résidus de chaleur. Economiser encore plus dans les limites de son propre périmètre est de plus en plus difficile. La prochaine étape logique est donc de collaborer en-dehors des limites des unités : entre les installations de production, entre les entreprises et entre les entreprises et les consommateurs de chaleur tertiaires et domestiques.

Dans ce regroupement ‘transfrontalier’ de forces, il y a aussi un important défi technique. Les fournisseurs de résidus de chaleur doivent garder suffisamment de flexibilité et les clients suffisamment de garanties en matière de disponibilités ; la récupération d’énergie doit être maximale afin de prévoir suffisamment de ‘paying power’ et de retour écologique. Afin de rendre tout cela réalisable, nous avons besoin d’une bonne infrastructure de base et d’une méthode de contrôle intelligente. Grontmij réalise depuis des années ce genre de réseaux de chaleur dans différents pays européens qui suivent déjà cette tendance. La Belgique ne peut donc plus y échapper non plus (voir ‘Les réseaux de chaleur en progression chez nous’ à la p.8).

Les réseaux de chaleur ont aussi un prix. Mais nous fournissons à notre communauté et industrie,

pour une durée de plusieurs décennies, une infrastructure de base pour une énergie propre et une valorisation locale d’un résidu de produit. Cela en vaut la peine, non ?

Des réseaux électriques intelligents ont une fonction similaire. Nous devons faire face à une moindre disponibilité de la production traditionnelle, une utilisation accrue d’électricité pour les pompes à chaleur et le transport et l’augmentation de la pénétration d’énergie renouvelable décentralisée et variable.

Les défis sont l’entretien de la sécurité de livraison et la fiabilité. Les smart grids nous aideront à garder les coûts sous contrôle. Grontmij est également impliquée dans cette thématique: avec Alexander Daenen comme membre du Conseil d’Administration de Smart Grids Flanders, avec le soutien et l’initiation d’activité autour de smart grids et la mise à disposition d’orateurs lors de journées d’études et de séminaires comme la journée d’études à propos des entreprises de production d’énergie de Smart Grids Flanders (18 septembre dernier), la Smart Grid School (8 octobre dernier) et le séminaire concernant les réseaux de chaleur de Smart Grids Flanders (25 novembre).

L’évolution vers des réseaux énergétiques intelligents pour la chaleur et l’électricité a réellement commencée!

Patrick Van de VeldeBusiness Line Director Industry, Water & Energy Services

Notre paysage énergétique évolue de jour en jour. Il est certain que nous aurons à faire, dans les 10 années à venir, à des défis et des changements plus importants que lors des derniers 100 ans!

Tension in the industry

For many it’s self-evident: we produce electricity, we transport electricity, we consume electricity. That a serious dip in supply could occur was not often thought about until recently. Now that a shortage threatens because three nuclear reactors are shut down, our confidence in the readiness of electricity production and distribution has received a hefty blow. As a partner of Elia in Belgium (see page 7) Grontmij has a strong commitment to the accelerated modernization of the high voltage network and high-voltage substations in our country. Meanwhile a lot of industrial companies are relying on Grontmij to realize energy projects.



E L E C T R I C I T Y

Industry generates its own electricityPartly in response to the supply uncertainty, increasing numbers of industrial companies are choosing to generate electricity themselves. This way they are arming themselves in order to counterbalance a longer blackout in supply.

However that is not the first and only reason why companies are conducting energy studies and drawing up energy plans and building power plants. The costing details are also clear. Energy-intensive companies that produce electricity themselves are saving on the necessary costs for the purchase of electricity in the long-term. They use for example, an excess of steam for the production of electricity. They then sell the surpluses to the suppliers of electrical power. Hence a double benefit.

Another very practical reason to be concerned with the electricity issue is that electric installations from previous years need to be renewed in accordance with the RD (Royal Decree or KB) 4/12/12. This describes the minimum requirements for the safety of electrical installations on jobs. The KB requires the employer to straighten out the documentation of the electrical installation, as well as raising the safety level thereof with the aid of a risk analysis relating to 11 imposed risks (see box).

Clients can also contact Grontmij to work out and conduct modifications to the electricity network. To understand the costs and benefits of a (large) investment in a power plant for example, Grontmij

describes and calculates possible scenarios. Grontmij is specialised both electrically and structurally. Electrically in order to make the necessary cable calculations (protection, types of cables, ...) and draw up specifications for the electrical installations (high-voltage, medium voltage and low voltage boards and transformer boards). Structurally for the purpose of describing

technical conditions for high and medium voltage stations (such as strength calculations) and in order to make provisions for the purpose of laying and connecting cables.

Absolutely no easy task, especially when you know that even coming close to a high voltage cable can be extremely dangerous.

With the KB 4/12/12, the legislator aims to increase the safety level of electrical installations. Employers are required to finalise the documentation (diagrams, cable calculations, etc.) of their electrical installations. They must also carry out a risk assessment (for 11 imposed risks) on all old electrical installations (01/01/1983) by 31/12/2014. From now on this risk analysis must always be prepared for newly installed electrical installations. Preventative measures resulting from this risk assessment should be implemented for old installations at the latest by 31/12/2016.

For the application of the RD, Grontmij offers the necessary support in:

� Layout and as-built locations of electrical schematics;� Drafting of short circuit and cable calculations on all voltage levels (high voltage, medium voltage and low voltage);� Making an inventory for and assisting in conducting the risk analysis. For making the inventory, Grontmij has drafted and implemented a check-list per risk in an automated database. Thus, the inventory can be done efficiently and in detail.

Thanks to all its available expertise, Grontmij is ideally placed to help with the develop-ment of solutions for potential issues that arise from the risk analysis and calculations.

Commitment to increasing the safety of electrical installations





In order to process 18 million tonnes of raw materials, the necessary energy is required. Total Raffinaderij Antwerpen transforms the voltage on its site to medium and low voltage via substations under its own management. The necessary power is distributed from these stations to the various production units.

Currently one of the many substations still houses a combination of medium and low voltage switchgear with associated transformers. When a renovation for medium voltage claimed the total space, it was decided to house low voltage installations in a new building.

The power processed in the substation is so crucial for the continuation of production

that it must be guaranteed at all times. The new design has therefore been constructed as ‘blast resistant’ and ensures that the substation is able to withstand the pressure waves of an explosion.

After the removal and conversion of the low voltage switchgear, the existing building can be renovated. All medium voltage switchgear and the related construction techniques are being replaced in the run with this.

Total Raffinaderij Antwerpen has entrusted both projects to the Grontmij energy team. This team is responsible for the complete detailed design of the plant, supported by colleagues from civil engineering and building services.

Grontmij helps Sadaci to make electricity supply safe

Sadaci, part of the international MOLYMET group, is a world leader in the production and toll conversion of molybdenum alloys. At its site in the Ghent Canal Zone, the company manufactures molybdenum containing products (roasted molybdenum concentrate and ferro molybdenum).

In order to provide all the activities on the site with the necessary power, until the end of 2015 Sadaci is using a 150 kV substation with a capacity of 100 MVA. After this date, network operator Elia is taking this substation out of service, partly because Sadaci’s consumption has declined sharply and is too low for a high voltage substation of this size. A 12 kV substation is replacing it. Such a decision is radical for an industrial customer. Not only does the new substation have to be installed and connected, the existing electricity infrastructure and Sadaci’s electricity network is also due for renewal. Sadaci is investing 2 million euros for this. Grontmij is supporting the company in securing the power supply to the site so that power interruptions are avoided. The experience and know-how that Grontmij has acquired during the projects with Elia also stand in good stead for Sadaci.

Grontmij is also providing Sadaci the necessary advice in the discussions with electricity supplier Eandis. Ultimately a sound technical solution with high availability and ample expansion possibilities for the future has been elaborated for Sadaci. Through logic diagrams, Grontmij is enabling Sadaci to acquire insight into the operation of the plant so that it can manage it itself. ‘Grontmij is the perfect match for us with know-how that we do not have. This coupled with our knowledge of the installations means that we are securing our electricity supplies for the future. Essential indeed for the survival of our operation here in Ghent’, says Luc Demuytere, Sadaci Project Engineer. This additional know-how for Sadaci consists of the deployment of high-voltage and medium-voltage knowledge, knowledge of and experience with the methodologies of Elia and Eandis, a good relationship with suppliers, the development of short-circuit and cable calculations, the making of logic diagrams, etc.

In 2012 Elia awarded Grontmij the contract to steer the extension of the Lixhe sub-station in the right direction. The extension of this high voltage substation is crucial for the further development of the Belgian electricity network and the link with the Netherlands. As main contractor Grontmij was responsible for the engineering and the construction. The total Investment for Elia amounts to 4.5 million euros.

The conversion and extension of the 380kV/220kV/15kV substation in Lixhe - located in the Hamlet of the same name,

north of Liege just next to the border with the Netherlands - is a crucial part of the further expansion of the electrical network and the link with the Netherlands.

In order to also meet the constantly changing demand of power supply in the Liege region, the existing 220kV field has been expanded with an additional field.

That field is coupled to a newly provided 220kV/15kV transformer. The objective of the 220kV field is to distribute the electric power, which is transported through Belgium via the high voltage lines, to Tecteo, the local distribution network manager.

The field is both a large On/Off switch for the purpose of disconnecting part of the power supply from the Belgian grid and also as a transformer for converting the high 220kV voltage to a lower 15kV voltage. Transformation is necessary since, from an energy point of view, it is better

to transport electric power over a large distance at higher voltages. The loss of power is significantly reduced at higher voltages.

The total Investment for Elia amounts to 4.5 million euros. The new substation was successfully put into service before the summer of 2014.

When it comes to district heating, Northern Europe is the leader. District heating

there, is an integral part of urban planning and energy supply. In Belgium,

the phenomenon is rather marginal. The first tentative steps are now still being made,

under the influence of the Green Heat Action Plan (Actieplan Groene Warmte) of

the Flemish government that financially supports the production of green heat.

The new energy policy agreement (Energiebeleids overeenkomst or EBO) also obliges

companies entering into it to verify the feasibility for heat integration. Heat networks

are often a sustainable form of energy supply. The transported heat is mostly residual

heat, which would otherwise be lost, or heat that is generated in a sustainable manner

(green heat).

In Germany, the largest geothermal heating plant was opened south of Munich. With this project, Stadtwerke München (SWM) set a milestone for the sustainable use and development of renewable energy. The CHP plant generates green electricity for 16,000 households. At the same time it provides households in Sauerlach with eco- friendly heat. The amount of geothermal energy provided is also worth mentioning. This enables us to be more independent of solar and wind energy.

By 2025, Stadtwerke München wants to produce as much green electricity in its own facilities as the City of Munich consumes. The new power plant generates an electrical output of approx. 6 MW and a thermal output of approx. 4 MW. The required drilling slots have a length of approx. 5 km and extend to a depth of approx. 4.2 km.

Grontmij is extremely proud of the successful completion of the project, following several years of planning activity. The specific challenges with the conversion of geothermal energy into electricity and heat require specialised equipment and technical know-how. Grontmij was involved in the conceptual and detailed design, preparation and follow-up of permits, licensing planning, construction management and validation of the documentation.

The concept of district heating is relatively simple: water transports heat from one or more sources to consumers. In practice, district heating projects require an integrated and multidisciplinary approach. In order to succeed, questions from various disciplines need answering: aligning supply and demand of heat, economic and financial aspects, total cost of ownership, water quality, piping, intelligent control, legal aspects, security of supply, optimal routing, thermal expansions, horizontal drilling, substations, etc.

Grontmij can do thisGrontmij guides customers from A to Z when it comes to projects for district heating networks. Grontmij not only has all the disciplines needed for this in-house, but thanks to its presence in countries such as the Netherlands, Germany and Denmark, where heat networks are established, Grontmij also has the available experience to effectively realize heat networks.

Combining disciplinesGrontmij Belgium has very extensive know-how and experience in the various

disciplines that come together in a district heating project: energy consultancy, industrial engineering, engineering & routing of various piping systems, expertise in horizontal drilling under waterways or roads, drafting of technical tendering documents, water in an industrial context, city planning.

Also thanks to knowledge sharing and continuous further training, we are able to support customers in the complete value chain of district heating projects. This includes the generation of heat via district heating (industrial waste heat, CHP, waste incineration, geothermal energy, high temperature heat pumps, power to heat, ...) transportation and consumption (industry, tertiary sector, residential, ...). Thermal buffering to align thermal consumption with demand is also part of our expertise.

From A to Z?(Pre)feasibility studies, permit requests, routing, industrial land surveying, basic engineering, detailed engineering. Customers can get help from Grontmij for truly every project phase.

Grontmij has been awarded a prestigious district heating project for MIROM. It is one of the first major district heating projects in Belgium in recent years. In order to use the full potential of Grontmij’s interdisciplinary knowledge, a cross-border team of Grontmij Belgium and Grontmij Netherlands has been created for this project.

MIROM has been providing its clients with district heating for over 30 years, using heat recuperation on two waste incinerators. The incinerators could provide more clients with heat, but this requires a substantial expansion of the district heating grid. The future clients who will connect to the heat grid are an eco-friendly SME business park, a sport complex, an exposition hall and an industrial client. In order to supply 1000 new dwellings with sustainable heating Eandis is building a district heating grid which will eventually connect to the grid Grontmij is building. This results in a challenging multi-stakeholder environment in which Grontmij operates.

This is one of the largest district heat expansions in Belgium in recent years. An international team of Grontmij with experts of the divisions in Belgium and the Netherlands has been formed to provide MIROM with state-of-the-art technology. Using Grontmij’s modern IT communication architecture, we are able to work on the same project cross-border without unacceptable costs and with maximum added value from our inter-national expertise.

We are honoured to have been chosen by MIROM to help them with the expansion of their district heating grid. It is only a small step to a more sustainable heating system in Belgium, but we are eager to set both the benchmark and a powerful example.

By doing so we hope to convince other companies to start valorizing their surplus heat.

In greenhouse cultivation CO2, heat and light are necessary in order to stimulate the plant growth. In this project, the generation of energy is replaced by waste heat and waste-CO2 from the industry in the immediate surroundings (fertilizer producer Yara). Horticulturists who want to set up their business in this area will therefore use 90% less gas than market gardeners in traditional greenhouse horticulture.

Innovative heat distribution network Heat from various industrial sources of

waste heat in the area is transported to the glasshouse horticultural businesses through insulated pipelines. This innovative heating network had to comply with strict requirements. On behalf of the customer, Grontmij is project leader and coordinates the activities of all important participants, such as market gardeners, heat producers and contractors.

Largest climate friendly horticultural area The customer of this project is WarmCO2. WarmCO2 will supply CO2 and heat to

the 10 market gardeners who establish their business in this newly to be developed area. The area is 168 hectares in size and is the largest and most climate-friendly horticultural area of the Netherlands. The horticultural greenhouses form part of Terneuzen’s Biopark.

Specialist knowledge Grontmij is the perfect party for taking care of this project due to the fact that it has in-house specialist knowledge in the field of renewable energy and industry and has experience in the management of multi-disciplinary projects.

Production at EVAL Europe in Zwijndrecht was shut down during the entire month of May. During this period the site was subjected to thorough maintenance. Grontmij also took care of some 50 engineering projects with an extensive site team. From preparation to implementation. After one month EVAL Europe was able to start up production again.

A safer and more efficient siteThis major shutdown at EVAL Europe was announced two to three years in advance. A detailed preparation of the very wide range of projects as regards content was important in order to optimally exploit the shutdown period. Activities that Grontmij took care of included planning, design work, work scheduling, permit requests, the selection and direction of contractors, quality control and the smooth start-up of different production systems.

EPCm in the scopeIn addition to dozens of smaller projects, Grontmij also managed various EPCm assignments. An example of such a project was the installation of a new brine refrigeration unit for the production of frozen water. The Grontmij site team was responsible for the complete transaction, from the preparation of the specifications of the unit, to ordering it and the connection to the EVAL Europe system, as well as the disconnection of an old unit. Bringing the as-built status of the unit into the AIM system and the control of the invoicing were likewise in the hands of Grontmij.

Another EPCm assignment was the implementation of a safety PLC. Here also, the design, selection and purchase, along with the implementation of the system were steered in the right direction by Grontmij. A third EPCm project involved the overfill prevention security in EVAL Europe’s tank park. Up to now twelve tanks have been equipped with such a safety system that blocks the inlets and outlets to the tanks in case of overfilling or fire.

In addition to these projects, Grontmij was still working on the heat recovery on the site and on smaller multidisciplinary maintenance projects. Also all process column related activities – replacement of trays, inspection of internals and repair – are prepared, followed up and monitored by Grontmij.

The projects were implemented within timing and budget. A tight project manage-ment was possible thanks to the mass

know-how and experience that Grontmij has gained at EVAL Europe in the past 15 years. In combination with a structured approach, this ensured a well organised and controlled shutdown completion.

About KURARAY – EVAL EuropeKuraray - EVAL Europe produces 24,000 tonnes of EVAL™ EVOH per year in Zwijndrecht for the European, African and Middle East market. This synthetic resin forms an efficient gas and aroma barrier with a layer thickness of one micrometre. The product has numerous applications. For example, EVAL™ packaging keeps foodstuffs fresh longer and cosmetic products retain their scent longer. It also finds uses in the construction and automotive industries. For example, in fuel tanks. Equipped with a layer of EVAL™ they become lighter and evapora-tion is prevented. EVAL Europe is part of the Kuraray Group. The Japanese chemical giant consists of more than 80 companies and employs more than 7000 people worldwide.

A major shutdown at INEOS Oxide and EVAL Europe was announced two to three years in advance. A detailed preparation of the very wide range of projects as regards content was important in order to optimally exploit the shutdown period. The experience of Grontmij in the preparation of shutdowns, the familiarity with working for chemical companies and the knowledge of the INEOS and EVAL Europe sites were of decisive importance in working on these shutdowns.

Grontmij’s activities were focussed on the preparation of construction packages for the different disciplines and on delivering construction supervisors during the construction period. After one month INEOS Oxide was able to start up production again. Activities that Grontmij took care of included planning, design work and quality control during construction. In June 2013 INEOS and Grontmij signed a framework contract for the preparation and the shutdown services.

Large volume engineering studiesThe preparation of the shutdown on the INEOS Oxide site in Zwijndrecht was a complex entity of projects that were mostly interlinked with each other. In order to have everything done smoothly, a good planning was essential. The volume of engineering studies required was large, as well as the need for the preparation of the necessary Design and Construction Packages.

The scope of projects was very extensive, partly because a number of environmental projects were also planned in. For example, among other things, the main piperack was made completely asbestos free. Some larger projects in which Grontmij was responsible for the design: the installation of 2 new columns, the installation of a new steam letdown station and the installation of a new ethylene reduction station.

Integrated interdisciplinary project teamINEOS own organization was unable to manage the large amount of work alone, hence the demand for an integrated project team with Grontmij. That team consisted of a mix of INEOS employees and a core team from Grontmij, supplemented – in function of the needs – with the interdisciplinary backup of the different sites in Belgium. Disciplines such as piping, civil, instrumen-tation, equipment and process were represented therein.

Large shutdown at INEOS Oxide Maand stilstand optimaal benut bij INEOS Oxide en EVAL Europe

De grote shutdown van mei 2014 bij INEOS Oxide

en EVAL Europe in Zwijndrecht werd een twee

à drietal jaar op voorhand aangekondigd.

Een gedetailleerde voorbereiding op de voor

beide bedrijven inhoudelijk erg uiteenlopende

projecten was belangrijk om de periode van

stilstand optimaal te benutten. Bij EVAL Europe

nam Grontmij meer dan 50 projecten voor

haar rekening, waaronder ook enkele EPCm-

opdrachten. Een strak projectmanagement was

mogelijk dankzij de massa kennis en ervaring die

Grontmij in de voorbije 15 jaar bij EVAL Europe

heeft opgebouwd. Dit in combinatie met een

gestructureerde aanpak zorgde voor een goed

georganiseerde en gecontroleerde shutdown-

afwikkeling. Ook voor INEOS Oxide stonden een

40-tal multidisciplinaire engineeringprojecten

op de planning. Een uitgebreid geïntegreerd

projectteam van INEOS en Grontmij leidde alles

in goede banen. De meeste projecten waren op

één of andere manier aan elkaar gelinkt. Een

goede planning was dan ook essentieel. Grontmij

versterkte het projectteam met experts in piping,

civil, instrumentatie, equipment en process.

Un mois d’arrêt utilisé de façon optimale chez INEOS Oxide et EVAL EVAL Europe

Le grand shutdown du mois de mai 2014 chez

INEOS Oxide en EVAL Europe à Zwijndrecht avait

déjà été annoncé il y a deux à trois ans. Une

préparation détaillée des projets, fondamentale-

ment très différents pour les deux entreprises,

était importante afin de pouvoir utiliser de façon

optimale les périodes d’arrêt. Chez EVAL Europe,

Grontmij a pris en charge plus de 50 projets, dont

également quelques missions EPCm. Une gestion

de projets serrée a été rendue possible grâce

à la connaissance et l’expérience élargies que

Grontmij a pu acquérir ces 15 dernières années

chez EVAL Europe. Il s’agit d’une combinaison

avec une approche structurée qui a permis un

bon déroulement contrôlé du shutdown.

Pour INEOS Oxide, il y avait également une

quarantaines de projets d’ingénierie

pluridisciplinaires au planning. Une équipe

de projet élargie et intégrée chez INEOS et une

équipe propre à Grontmij ont permis de mener

cette mission à bien. La plupart des projets

étaient d’une manière ou d’une autre liés les uns

aux autres. Un bon planning était donc aussi

essentiel. Grontmij a renforcé l’équipe de projet

avec des experts en piping, génie civil,

instrumentation, équipement et process.

At INEOS Oxide in Zwijndrecht production was shut down during the entire month of May. During this period thorough maintenance work on the equipment was carried out. Also modifications and extensions were in the scope of the shut down. Grontmij was asked to assist in the detailed engineering of some 40 multidisciplinary engineering projects. An extensive site team worked together with INEOS in an integrated project team.

In early 2015 a refurbished control room will be commissioned for the operation of the LDPE site of Zwijndrecht based Speciality Polymers Antwerp (SPA); SPA is part of Borealis. Currently, the construction and renovation are in full swing. Grontmij is a partner in this project and its responsibilities include the electrical and instrumental engineering of this state-of-the-art control room.

The project started in February 2014 and ends in the first quarter of 2015. This short time period demands strict timing and strong project management. The operation of the two high-pressure LDPE reactors may not be compromised under any circum-stances. To this end the existing TDC3000 operator interface must also be upgraded to the Experion platform.

Unconventional approachA major challenge of the project is to let the various engineering disciplines involved and the firm specialized in the renovation of control rooms work together optimally. The timely finishing of the electrical and instrumentation design and the associated packages was particularly tight. The civil engineering part was also addressed. Grontmij managed to respect the schedule, thanks to the close cooperation with the project lead from SPA who took to heart several of Grontmij’s tasks at the busiest time, including the civil follow-up of the activities. Once the packages were made

available Grontmij took back over the follow-up, so that SPA could focus on the project control, project administration and cost control.

One month standstillThe implementation of the project proceeded in four stages. In the first phase, the rooms around the current control room were cleared, stripped and restyled. In the second phase, in a planned shutdown period of one month, the control room was addressed and the old control panel was moved to another location. During this period the control of the LDPE unit was

done via a specially set up control console. After the standstill, the start up and operation will be done via the old relocated console. This console will continue to remain in use until the new equipment can completely take over from the old. In the third phase, the Experion platform is installed in order to be used later as test and panel design for the software transition from Native Window Displays to HMI Web Displays. Finally, SPA will take the relocated old panel out of service. From that moment on the test and design panel becomes the fully fledged new operating panel of the operator in the control room.

BrownfieldThe new ladle furnace project is split into a greenfield and brownfield part. As far as

the brownfield is concerned, the new ladle furnace installation is integrated into one of the four ladle-metallurgy lines of the

ArcelorMittal Gent’s steel plant. The electro-mechanical part of the installation is a turn key project. Grontmij played an important role in the adaptation of the total current (including supply lines) and additional infrastructure around the installation. Additional platforms and spaces, including for transformers, hydraulics and switch-box received a place in the whole. Grontmij was also responsible for the engineering of new utilities, the modification of existing pipework and the cable work. This work was started in June 2014 and carried out within six months. Furthermore, we have adjusted the furnace mode, the steel ladles, the steel carts (for transporting the ladles), and the maintenance modes for the ladles, so that rinsing with Argon is possible through the bottom of the steel ladle.

GreenfieldA new furnace also requires the necessary auxiliary equipment: a new filter installation (turn key) and a complete cooling system. Grontmij drafted the lay-out study, the concepts and the specifications of the necessary equipment. A new warehouse,

New ladle furnace for ArcelorMittal Gent ArcelorMittal Gent has put a ladle furnace (*) into use in order to meet the growing demand for better, stronger types of steel with a low sulphur content. The steel giant asked Grontmij to carry out the conceptual, basic and detailed engineering, to draft a detailed budget, to process the requests to quote and orders, and to take the role of being responsible for ordering during construction. The cooperation has run to everyone’s satisfaction.

new pump room, cooling towers, piping bridge and new substation are all now accommodated in the new construction. In order to improve the accessibility of the four ladle metallurgy lines, an ultramodern control room was centrally provided for in the installation. The operator now controls these lines with a new control console that has been designed from scratch. The realization of the whole took a year to complete.

Interdisciplinary assetDuring the entire construction period, ArcelorMittal Gent involved Grontmij to be responsible for orders with the checking of the materials supplied and the solving of problems on the site. This was the task of the project manager. Other engineering disciplines deployed by Grontmij were project controls, mechanical, civil, process, equipment, piping, electrical engineering and instrumentation.

ArcelorMittal Gent heeft een nieuwe pannenoven of ‘ladle furnace’ in gebruik genomen. De staalreus vroeg aan Grontmij om de conceptuele, basic en detailed engineering uit te voeren, een gedetailleerd budget op te stellen, de prijsvragen en bestellingen te verwerken en de rol van bestelverantwoordelijke op te nemen tijdens de constructie. Het project is opgesplitst in een greenfield en brownfield gedeelte.

Wat de brownfield betreft is de nieuwe pannen-oveninstallatie geïntegreerd op één van de vier panmetallurgielijnen van de staalfabriek van ArcelorMittal Gent. Het elektromechanisch deel van de installatie is een turn key project. Grontmij speelde een belangrijke rol in de aanpassing van de volledige bestaande (inclusief toevoerlijnen) en bijkomende infrastructuur rond de installatie. Een nieuwe oven vraagt eveneens de nodige hulpinstallaties: een nieuwe filterinstallatie (turn key) en een volledig koelsysteem. Grontmij werkte de lay-out studie, de concepten en de specificatie van het nodigde equipement uit.

Een nieuw magazijn, nieuwe pompenzaal, koeltoren, pijpenbrug en nieuw onderstation kregen onderdak in de nieuwbouw. Om de bereikbaarheid van de vier panmetallurgielijnen te verbeteren, werd een hypermoderne controlekamer centraal in de installatie voorzien.

ArcelorMittal Gent a mis en service un nouveau ‘ladle furnace’. Le géant de l’acier a demandé à Grontmij prendre en charge la conception, le basic et le detailed engineering, d’établir un budget détaillé, de traiter les demandes de prix et les commandes et de prendre en charge le rôle de responsable des commandes durant la construction. Le projet a été divisé en une partie greenfield et une partie brownfield.

En ce qui concerne le brownfield, la nouvelle installation de ‘ladle furnace’ a été intégrée dans une des quatre lignes de métallurgie en poche de l’usine sidérurgique d’ArcelorMittal Gent. La partie électromécanique de l’installation est un projet turn key. Grontmij a joué un rôle important dans la modification de l’entièreté de l’infrastructure existante (conduite d’approvisionnement incluse) et future autour de l’installation. Un nouveau four demande également les installations de secours adéquates: une nouvelle installation de filtration (turn key) et un système de refroidissement complet. Grontmij a réalisé l’étude du lay-out et les conceptions et spécifications des équipements nécessaires.

Un nouvel entrepôt, une nouvelle salles des pompes, une tour de refroidissement, un chemin à câbles et une nouvelle sous-station ont été hébergés dans le nouveau bâtiment. Afin d’améliorer l’accessibilité des quatre lignes de métallurgie de poche, une nouvelle salle de contrôle hypermoderne a été prévue au centre des installations.

*Ladle furnaceA ladle furnace is an installation with which 300 tons of liquid steel in a ladle may be heated up to the desired temperature. The heating is done by transferring 3 phase AC electrical energy via 3 graphite electrodes, to the steel. By adding Argon through the bottom of the steel ladle, a vortex is created in the ladle so that the additives are optimally mixed with the steel (chemical homogenization and desulphurisation of the steel). The combination of additives, mixing and heating make it possible to produce the next generation of High Strength Steel (HSS), which is more than 4 times stronger than normal steel.

Thanks to its 360° experience, Grontmij is the ideal partner for tank park projects no matter what the size. Almost every aspect of the tank park exploitation is picked up via one central point of contact and steered in the right direction. From energy optimisation projects to policy advice and calamity reports, we are able to supervise the entire life cycle of your system if so desired.

The cases at Noord Natie Terminals (master plan development), ADPO (energy monitoring) and TOA show that we deploy our interdisciplinary know-how across the various knowledge domains for tank farms. Our engineers give advice on using the best type of tanks and materials as well as recommendations on the best methods for energy optimization.

Think tank, think Grontmij: projects at Noord Natie Terminals, ADPO and Total Olefins Antwerp

In the Port of Antwerp, ADPO disposes of more than 290,000 m³ of tank storage capacity of which the tanks sizes vary from 150 m³ up to 5000 m³. With its 120,000 m³ stainless steel storage tank capacity, ADPO is the world’s largest terminal of this type. ADPO stores oil additives, intermediates and bulk products but specializes in fine chemicals.

As an audit covenant company ADPO is obliged to conduct an annual energy monitoring. Grontmij carried this out for the site in Kallo and has further refined the energy balance at the request of the Flanders Audit Covenant Verification Office. Grontmij’s analyses led to some surprising insights. For example, additional possibilities for energy savings came to light and the project for the implementation of steam flow meters has been adjusted in order to ensure a better monitoring of the energy consumption.

ADPO case: refinement of the energy balance

In the Port of Antwerp, Noord Natie Terminals is working on a capacity expansion of 90,000 m³. The new tanks, with a capacity between 1250 and 5000 m³ for the storage of liquids, are coming on to a site of six hectares. New berths for the latest generation of chemical tankers are an added asset.

Grontmij is taking responsibility for the engineering of the four tank farms in close cooperation with the client. Grontmij has built up years of experience and expertise in the development of tank farms. Early in 2014 we finalized the extended basic engineering and the budget estimate of the four new tank farms.

In addition to the determination and calculation of the basic data by our process department, the 3D model of the tank farms and the detailed P&ID’s are at the heart of this project. Functionality and lay-out form

the key to success. Grontmij’s industrial surveyors also played a leading role in this. They measured the entire site and mapped out the necessary deviations for the start-up of the engineering.

For those who know the Scheldelaan in the Port of Antwerp, the tank farms of Total easily come to mind. Grontmij is involved in the conversion of a specific tank in one of those farms: the aromatics tank farm of Total Olefins Antwerp (TOA). By the end of 2014 this has to be adapted to the stringent requirements for the storage of the C7 reformate product combination, (a mixture of benzene, toluene and heptane). The Vlarem (Flemish Environmental Protection (General Provisions) Act demands an emission reduction of 98% for this extremely volatile product requirement. In order to achieve that desired result, the installation of a ‘full contact’ type of Internal Floating Roof (IFR) has been opted for in consultation with the client.

With this type of IFR, there are no C7 reformate fumes present between the roof of the tank and the internal floating roof. A floating roof such as this consists of

lightweight aluminium panels with a honeycomb structure. This structure provides strength and stability with minimal use of materials. TOA is reconstructing the tank into a freely breathing tank. This requires new air vents. The advantage of this is that the atmosphere between the fixed and the internal roof of the tank remains below the lower explosive limit and that it is not necessary to render it inert with nitrogen.

For this project, Grontmij has fitted the engineering and technical requirements within the framework contract that we have with TOA. The necessary adjustments to connections, pipelines and instrumentation are provided. Furthermore, our specialists have drafted the necessary requisitions for converting the tank, evaluated the offers from IFR suppliers and made a selection. The special experience with codes such as API 650 and API 653 and the VLAREM legislation has also been used.

Grontmij joins consortium with Ateim for projects at ArcelorMittal Liège

In March 2014 ArcelorMittal Liège signed a framework contract with the French engineering firm Ateim and with Grontmij. Both engineering firms are joining forces in a consortium to serve the steel giant’s interdisciplinary projects in the Liège region. This way ArcelorMittal benefits from the experience that Ateim has with projects for ArcelorMittal in France. And thanks to the good experience and relationship with Grontmij via the site team in Ghent and the back offices in Zelzate, Antwerp, Louvain-la-Neuve and Herentals, ArcelorMittal can count on a complete range of services.

The contract will last at least 3 years and joins, for several projects, the huge investments plan (138 million Euro) of ArcelorMittal Liège. Grontmij and Ateim are in the throes of expanding the joint site team in ArcelorMittal’s offices in Flémalle. This location includes the engineering support dept. of ArcelorMittal Liège and it is situated centrally and close to the sites in Tilleur, Kessales, Ivoz-Ramet and Marchin. In consultation with the client, Ateim and Grontmij are drawing up a project portfolio for the coming years.

An example (part of the 138M€ envelope) meanwhile is the EPCm project for the implementation of a new organic coating line in an existing factory building on the Marchin site. Applications will be mainly in the automotive industry and the world of canning (food and beverage packaging). Disciplines involved from Grontmij include process engineering, electricity, instrumentation, automation, civil engineering, mechanics, procurement, safety and environmental compliance and construction management.

Grontmij is currently working on the extended basic engineering study of the new line. After receiving the go ahead from ArcelorMittal, the project will commence construction at the end of 2015.

Uit de bijdragen ‘Spanning in de industrie’ (p.5) en ‘Warmte netten nu ook bij ons in opmars’ (p.8) blijkt dat er de komende periode heel wat te doen zal zijn rond elektrici-teit en warmte als dragers van energie. Investeringen in productie en distributie dringen zich op, maar zullen die ook daadwerkelijk gebeuren? Als projecten het daglicht zien, staat Grontmij in ieder geval klaar om waar nodig van dienst te zijn en de evolutie naar slimme energienetten te begeleiden.

Dat we geëngageerd zijn blijkt ook uit onze actieve deelname in Smart Grids Flanders (zie voorwoord). En dat niet enkel het engineeringluik van dit verhaal stevig onder dak zit bij Grontmij, maar ook de consulting verankerd is, komt tot uiting in de oprichting van een heus departement Consulting Services binnen Grontmij, met daarbij de Environmental Consulting services als één van de clusters.

Ondertussen staan de veranderingen buitenshuis niet stil. Grontmij bereidt er zich met grote zorg op voor. De nieuwe Energiebeleidsovereenkomst (EBO) gaat op 1 januari 2015 van start. Meerdere industriële bedrijven laten zich door Grontmij doorheen het traject begeleiden. Maar het is duidelijk, heel wat bedrijven hebben na twee ronden Benchmarking- en Audit convenant mooie efficiëntieverhogingen gerealiseerd. Nog meer besparen binnen de eigen grenzen wordt moeilijk. Samenwerken tussen productie-installaties, tussen bedrijven onderling, en tussen bedrijven en tertiaire en huishoudelijke warmteafnemers is een logische volgende keuze.

Ook in het domein van de waterzuiveringen blijft Grontmij innovatief werken. Niet alleen past Grontmij de zelfontwikkelde SHARON®-technologie toe (bijvoorbeeld op de rioolwater-zuiveringsinstallatie van stad Leuven). Ook ontwikkelde Grontmij de Regenerator, waardoor afvalwaterzuivering evolueert naar energieproductie en grondstoffenfabriek!

Au vu des contributions ‘Tension dans l’industrie’ (p.5) et ‘Les réseaux de chaleur en progression chez nous’ (p.8), il apparaît que dans le courant de la période à venir, il y aura pas mal de chose à faire autour de l’électricité et de la chaleur en tant que porteurs d’énergie. Des investissement dans la production et dans la distribution s’imposent, mais auront-ils bel et bien lieu ? Lorsque des projets verront le jour, Grontmij sera en tout cas prêt à proposer ses services et encadrer l’évolution vers des réseaux de chaleur intelligents où cela s’avère nécessaire.

Le fait que nous sommes engagés émane également de notre participation active à Smart Grids Flanders (voir préface). De par le fait que la partie Engineering est fortement ancrée chez Grontmij, et que cela est également le cas au niveau de la Consultance, se manifeste par la création d’un imposant département Consulting Services au sein de Grontmij, ayant l’Environmental Consulting services comme cluster.

Entre-temps, les changements se passant en-dehors de Grontmij ne s’arrêtent pas. Grontmij s’y prépare donc avec beaucoup de soin. La nouvelle Convention Energétique entre en vigueur à partir du 1er janvier 2015 (en Flandre). Plusieurs entreprises se font déjà aider par Grontmij. Et c’est très clair, un certain nombre d’entreprises ont déjà réalisé de belles améliorations en matière d’efficacité après avoir participé à 2 tours de Benchmarking et d’Auditconvenant. Réaliser encore plus d’économies en interne devient difficile. Une collaboration entre les installations de production, entre les entreprises, et entre les entreprises et les consommateurs de chaleurs tertiaires et domestiques est donc le prochain choix logique.

Grontmij continue de travailler de façon innovante dans le domaine du traitement des eaux usées. Grontmij ne fait pas qu’appliquer sa propre technologie SHARON® (par exemple sur l’installation de traitemant des eaux d’égouttage de la ville Louvain). Grontmij a également développé Regenerator (le Régénérateur) permettant de faire évoluer le traitement des eaux usées en production d’énergie et en usine de matières premières!

Aquafin has given Grontmij the assignment of realizing a SHARON installation at the sewage treatment plant (STP) for the city of Leuven. Grontmij applies the SHARON process as a technique for removing nitrogen from wastewater with high concentrations of ammonia. This technology saves energy, is cost effective, quick to install and takes up little space in comparison to conventional systems. In partnership with the Delft University of Technology (TU Delft), Grontmij Netherlands has a patent on the technology and applies this to numerous water purification plants. Now it’s Aquafin’s turn. A first for Flanders!

In addition to the process expertise, Grontmij Netherlands is providing the preliminary design and patent. Grontmij Belgium is taking care of the translation to a public tender dossier that satisfies the requirements of the client, the local regulations and the project-specific technical requirements. The SHARON installation is currently being installed in the sewage treatment plant of Leuven for

the purpose of taking it into service at the end of 2014. During the start-up of the unit, Grontmij is taking care of the necessary support, in respect of both the process and the software control thereof.

About SHARONSHARON stands for ‘Stable High activity Ammonia Removal over Nitrite’. In the SHARON process, ammonia is converted to nitrogen gas via nitrite by means of bacteria (see illustration). This is done without the involvement of nitrate. In comparison with a normal process, nitrogen removal via this nitrite route saves 25% of the aeration energy and requires 40% less carbon for denitrification. Also 40% less bio-sludge is produced. This means substantial cost and energy savings at various levels in the operational management. Moreover SHARON reduces the nitrogen content and increases the total nitrogen yield, meaning the quality of treated wastewater improves significantly.

Specifically for the RWZI LeuvenThe SHARON system was initially developed for the treatment of rejection water from

sewage treatment plants. Rejection water is nitrogen-rich residual water released from sludge dewatering. This residual water represents 10 to 40% of the total quantity of nitrogen of a sewage treatment plant. In addition to the rejection water, a nitrogen-rich condensate stream coming from the sludge drier is being introduced at the installation in Leuven. This condensate stream is rich in carbon, whereby no external carbon source such as methanol, is required for denitrification. The adjustment and control of both process streams in the SHARON process demands special attention for this project. This applies both to the load and to the reactor temperature.

Purifying wastewater is an energy intensive activity. However the implementation of sustainable techniques often causes an additional problem. A proper alignment of available technologies, often jointly developed by Grontmij, is necessary to reach maximum synergy. Grontmij has succeeded in this with a new concept: the Regenerator.

With the Regenerator, Grontmij changes a wastewater treatment unit into a sustainability station that produces useful raw materials with various technologies. By means of the correct combination, the purification process becomes truly sustainable and a maximum amount of energy and a specific series of components can be recovered from the wastewater. Thus fertilizer can be produced from wastewater by means of struvite formation, in combination with a process (SHARON®, DEMON®, EssDe®) that removes nitrogen energy-efficiently. The latter processes allow

us to maximize the energy recuperation using specific techniques that increase the production of biogas (Salsnes filter, Lysotherm®, EssDe®).

Grontmij also uses the Regenerator concept for industry, where the efficient handling of raw materials is high on the agenda. In Belgium also, this concept is needed

in order to work with maximum sustainability inside and outside the industry. The stricter regulations and ageing infrastructure necessitate adjustments. Thus the perfect opportunity to take everything into account.

In 2012, Katoen Natie took over its Italian sector compatriot, Rivalta Scriva. The acquisition included a 121 hectare establish-ment in Tortona (of which 45 hectares are covered). In Parma, a storage area also came under the ownership of Katoen Natie. With this deal Katoen Natie was able to secure a fast connection between the Italian ports and the economic heart of Northern Italy.

Katoen Natie noted that energy costs were high on both sites. Therefore it gave Grontmij the assignment of carrying out an energy study, with the ultimate aim of significantly reducing these costs. Katoen Natie already had experience with Grontmij’s energy experts, including with the earlier review of the site in Antwerp. In a first phase Grontmij

started with the analysis of invoices and energy meters. Detailed energy accounting was not available. It soon became clear that the major consumers were cooling and lighting. On the basis of the various energy meters, Grontmij was able to draw up an accurate analysis of the consumption profile.

On site Grontmij conducted the necessary technical assessments of the cooling installations. A first screening of the opera-tional parameters and set points provided the necessary insights and first input in order to be able to ask for and analyse the necessary trendings from Belgium. From this info Grontmij was able to work out cost-cutting measures in consultation with Katoen Natie and in exchange, provide a budget.

For the analysis of the lighting, Grontmij also made a technical inventory and analysis of the situation on the spot. More than 50 warehouses were analysed and systematically assessed (extent of activity, condition of the installation, orientation of the lighting, daylight accessibility and light level, etc). Back in Belgium, for the warehouses with the highest consumption or the most potential for savings, Grontmij defined the concrete improvements. Grontmij also gave them general guidelines for optimal management and design of other warehouses.

The combination of good preparation, laying the right focus and the close cooperation with the customer have ensured that, despite the size of the site and the limited time locally, some major savings potentials have emerged from this energy study. Also, the smooth internal cooperation between the energy specialists and experts from other disciplines ensured great satisfaction at Katoen Natie.

In September, the Flemish Energy Agency (Vlaams Energieagentschap or VEA) gave more explanation on some actual implementation conditions of the EBO. There was still no clarity about the excise duty exemptions. The European Commission will shortly express an opinion about this. Based on previous (unofficial) signals it seems likely that the proposed excise duty exemptions will not be retained in their present form. Alternatives are being prepared.

General obligations The Flemish government ratified two separate energy policy agreements. One for the TEA industry (Tradable Emission Allowances, the European CO2 trading system) and one for the non-TEA industry. The obligations for both types are the same for all but a few implementation conditions.� Joining before 1 January 2015. � Drafting an energy plan (valid for the first 3 years after coming into effect) within approximately 13 months after joining. � Implementation of cost-effective measures (IRR > 14% or 12.5%, for resp. TEA and non-TEA). � Execution of a CHP potential study. Depending on the situation, an exemption may be requested for this or an earlier study that was carried out may be submitted (if still relevant).� Drafting annual monitoring report. � Implement an energy management system no later than 3 years after the EBO coming into effect.

ConcessionsBusinesses joining enjoy the following concessions.� (Alternative) Financial concession: with the probable rejection of the excise duty exemption work is being made of an alternative financial concession. More information follows.� No additional reporting about energy in the annual environmental report. � No additional targets with reference to energy for companies joining, unless imposed by the European Commission. � Possibility of investment support through ‘Ecologiepremie Plus’.

The use of flexible measures has been introduced in the new EBO. These are measures aimed at improving the supply chain efficiency, produce renewable energy, ... They can be used to replace one or more mandatory measures to be implemented.

Furthermore, ‘economic pardonableness’ is also a feature for companies that are in a difficult financial situation. They may obtain exemption for the implementation of cost-effective measures, as long as certain criteria are met.

More infoMore info about the EBO and the statutory obligations? Look on www.ebo-vlaanderen.be. You will also find the new templates and forms there.

Companies working together with Grontmij include for example ADPO (see p.18). Energy experts and consultants are guiding these companies through the entire EBO process. Other companies may also contact Grontmij for the purpose of viewing their own situation and to determine whether joining is meaningful for them.

Energy policy agreement starts on 1 January 2015

Grontmij guides companies through their EBO process

In April 2014 the Flemish government ratified the new energy policy agreement or EBO (Energiebeleidsovereenkomst) for the Flemish energy intensive businesses. EBO comes into effect on 1 January 2015. With this the government makes provision for a new policy instrument for the Benchmarking and Audit Covenant that expires at the end of 2014. Grontmij is guiding several industrial companies through the process.

Gassco focuses on safety with preventative gas pipeline control

On the Gassco site in Zeebrugge Grontmij looks after various engineering projects on a continuous basis. One of Grontmij’s assignments is the excavation of a gas pipeline for the purpose of conducting a visual inspection. In the autumn of 2014 Gassco is carrying out a preventative check on the underground pipeline that carries the Norwegian gas supplied to the reprocessing station in Zeebrugge.

During the annual preventative measure-ments Gassco identified that potential damage has occurred to the coating around the pipe. In order to investigate this further, Gassco has commissioned Grontmij to excavate and expose the gas pipeline so that a visual inspection of the pipe may be done. The investigation has no effect on the pipeline itself.

What makes the project a challenge is that the pipeline is four metres deep, in the De Kleiputten nature reserve, next to a railway line bed. The investigations are being conducted in the autumn in order to avoid the breeding season. After the conclusion of the work, Gassco has to restore the nature conservation area to its original state. Because the pipeline lies so deep next to a railway line, extra care is needed for the design of the excavation. Sheet piles have to be carefully driven. In doing so, combined excavation is done, both manu-ally and using cranes. The piles are placed perpendicularly so that a straight incline can be laid beside the bed as far as the pipeline. The last part of the excavation is being done manually for safety reasons.

Once the location of the potential damage has been exposed, the control may take place. Grontmij is responsible for the detailed study, the specifications, the contests, the drafting of the bid, the technical assessment of the contractors and the continuous presence on the ground of a construction manager who has experience of similar work at Fluxys.

Grontmij is also taking care of the work in the nature conservation area and the agreements with Infrabel with a view to the conservation of the bed. p.29



In the coming years the industrial appearance on the left bank of the port of Antwerp will have a distinctive green touch. The NV ‘Wind aan de Stroom’ (NV W@S), project developer of wind energy on the public domain of the left bank of the Scheldt, has commissioned Siemens Belgium for the supply and construction of wind turbines in this first phase. Right away, this becomes the first wind energy project for Siemens in Belgium. Grontmij has received the full confidence of Siemens and contracting party NV W@S for the engineering of all the necessary civil studies.

The project extends over an area of several square kilometres of harbour area with 14 sites on it with different historical backgrounds (including reclaimed land and the nearby docks). Therefore, using extensive geotechnical soil investigation, the geology and bearing capacity of the (sub)soil was first identified and listed. Thus an optimal foundation design has been elaborated per site.

In addition the crane hardstands also received considerable engineering attention. One of the challenges of the project is the installation of turbines on sites with limited space due to the high density of the industrial and port activities. Using giant cranes, the hub (the central component of the wind turbine), with a weight of 78 tons, will be positioned on top of a 115 metre high turbine mast. For such crane activities, the stability of the working platform is of the utmost importance. Secondly, there is the challenge for this crane hardstands to

take up as little as possible industrial space, both during the construction work and the final erection.

The turbines will be constructed at the sites of famous companies as Borealis, Indaver, Antwerp Gateway, Tabaknatie, Luiknatie, Norbert Dentressangle, Euroports, Global Container Services, Sea Port Terminals and Transport Van Loon.

Grontmij’s strength of expertise in the design and realization of wind farms, in conjunction with a local presence in various industrial companies in the port area, provides a lot of confidence to act as a technical partner in this ambitious project for Siemens.

Now the detailed engineering has been completed and the civil works can be assigned to a contractor, Grontmij is ready to take on the daily project management and supervision of the works. The foundation works start in November 2014. The first turbines will be operational by the summer of 2015. The first phase of the wind farm is good for an electricity production of about 100 gigawatt hours per year. Thus green electricity for about 30,000 households or multiple local companies. The entire wind farm will be completed by 2020.

Grontmij assists Siemens in the construction of its first wind farm in BelgiumOn assignment of wind turbine supplier Siemens, Grontmij is responsible for the detailed engineering and design of the new wind farm on the left bank of the river Scheldt in the port of Antwerp. Project developer ‘Wind aan de Stroom’ is the contracting party. In a first phase 11 to 14 wind turbines are being constructed, each with an electrical power of 3 megawatt.

Under the care of OVAM, both companies signed a cooperation agreement for the purpose of setting up a joint descriptive soil investigation. Grontmij started this investigation with a 3D site model wherein

the existing buildings, sewage system, geology, groundwater levels and concentrations per parameter are shown. Based on this, the parties determined a research strategy with monitoring wells

and MIP probing for the purpose of identifying the contaminants and evaluating the risk. The geological situation made the whole thing somewhat complex given the existence of 3 aquiferous layers that are separated by less permeable layers.

From Grontmij’s investigation it appears that there possibly are natural degradation processes going on. This was further investigated at a later stage in consultation with VITO. Completed dechlorination was shown by which the chlorinated hydro-carbons are broken down into harmless ethane and ethylene. The contamination could be limited in depth to the poorly permeable sand layer of Vlierzele approximately 15 m below ground surface level. Using soil air measurements, it has been demonstrated that there is no volatilization from the groundwater to the above lying workspaces.

Finally, the conclusion was that the contami-nation identified posed no risk to humans, ecotoxicological risk or risk of spread. A soil remediation was therefore not required.

The prestigious Blue Boulevard property project (Blauwe Boulevard) is well known in Hasselt and environs. A part of the Canal Basin in Hasselt is undergoing a real transformation. The old industrial site is being trans-formed into a brand new harbour area with dozens of complexes consisting of shops, offices, catering establishments, apartments and underground parking. The total area covers about 85,000 m².

Grontmij is carrying out various activities for multiple clients such as OVAM, The City of Hasselt, Aquafin/Infrax; these include soil surveys, designs for quay lowering and moving of collectors, layout of roads and squares. A stop for Spartacus, the first fast tram connection between Hasselt and the Dutch city of Maastricht, which Grontmij is working on with Witteveen+Bos, is also foreseen in the Blue Boulevard project.

Commissioned by the City of Hasselt, Grontmij has prepared a preliminary and descriptive soil investigation of the former industrial site. Active on the site were a jenever distillery, a city gasworks, a slaughterhouse, a factory for sanitary fittings and a gelatine factory. For OVAM, Grontmij conducted a descriptive soil investigation by a former fuel depot.

A remediation is called for. The site there is destined for the development of a city park. nv De Scheepvaart has also had a descriptive soil investigation carried out by Grontmij. This by the former filling points of the same fuel depot. The total area of the investigated site amounts to 50,000 m².

No soil remediation required at Dana Belgium and Bombardier Transportation

Soil of former industrial site in Hasselt under scrutiny

Commissioned by OVAM, Grontmij has conducted a descriptive soil investigation on the business sites of Bombardier Transportation Belgium NV and Dana Belgium NV in Bruges. On the boundary of both sites there was contamination arising from chlorinated solvents. In the past, both companies had activities wherein these solvents were used. Both of them also made use of a sewage system present on the site which is suspected of having played an important role in spreading the contamination.

Grontmij has all the know-how in house to solve any soil problem. Sometimes however, more than just policy related, technical and organisational know-how is needed. What if legal points of contention arise between different parties with a serious soil contamination? Between current operator(s), current owner(s), former operator(s), former owner(s), neighbours, ... Soil investigation and possible remediation bring high costs with them.

What is Grontmij able to do? A legal- scientific approach brings clarity about the cause of the contamination, the obligation to remediate, remediation liability, possible exemption from remediation obligation, ... As a legally competent soil expert, Grontmij ensures the maximum feasibility and probability of success of a legal procedure. By virtue of a qualitative legal-scientific approach, environmental lawyers gain closing arguments in order to make possible an informed substantiation of the procedure.

RoTS is responsible for the layout of the environmental hygiene ground surveys for both the main work and the preparatory work for the realization of the Oosterweel Link. The total volume of the ground excavation is estimated at a whopping 11.5 million m³. For comparison: for the construc-tion of the Deurganckdok Lock, about 9 million m³ of ground excavation is required.

The exploratory ground surveys (EGS’s) needed to identify and list the soil ingestion and expropriations are also being jointly prepared by Grontmij’s environmental specialists. In the event of serious soil contamination, there will be descriptive soil investigations (DSI’s), possibly followed by the preparation of soil remediation projects (SRP). RoTS has already drafted and/or put into execution dozens of EGS’s, some five DSI’s and equally as many SRP’s.

The largest soil remediation project within the Oosterweel Project is the clean-up of the highly contaminated sediment (with heavy metals, mineral oil and PAHs) from the Lobroekdok in Antwerp North. Radar technology from Grontmij also revealed that there are several wrecks of sunken ships at the bottom of the dock. Prior to the decontamination these ship wrecks have to be secured.

Finally, RoTS and more specifically the environmental experts from Grontmij are responsible for the evaluation of the asbestos and demolition inventories. These inventories were drawn up with a view to the demolition of one of the buildings along the route of the Oosterweel Link. In some cases, demolition specifications are being brought in line with the specifications that are drafted for soil remediation projects.

Contentious legal points with soil pollution

Ground surveys for the Oosterweel Link RoTS improves Antwerp’s quality of life with a tunnel solutionCommissioned by Beheersmaatschappij Antwerp Mobiel (BAM nv), the temporary RoTS consortium (comprising Grontmij and Witteveen+Bos) is making the design for a stacked tunnel. This tunnel replaces the bridges of the orbital round Antwerp and across the Albert Canal.

The project is being carried out by the THV Rechteroever Tunnelspecialisten (Right Bank Temporary Trading Company of Tunnel Specialists or ‘THV RoTS’), consisting of Grontmij and Witteveen+Bos. This combination has been working since 2012 on testing the technical and financial feasibility, developing the design and the pre-paration of the tender.

Studies on the technical and financial feasibility provided the engineers insight that it is better to replace the intended new bridges over the Albert Canal with a stacked tunnel.

The extra costs of a tunnel in relation to new bridges appeared to be acceptable. The noise disturbance for local residents decreases when this piece of the orbital disappears underground. In addition, extra space for a city park for example, results from a tunnel. Finally, the tunnel solution gives a better overview and thus a safer situation for road users of the orbital.

Commissioned by the ‘Beheersmaatschappij Antwerp Mobile (BAM nv), Grontmij – within the temporary RoTS consortium (THV Rechteroever TunnelSpecialisten) in which it is collaborating with Witteen+Bos – is carrying out various activities on the soil, as preparation for the laying of the Oosterweel Link. RoTS has been working since 2012 on testing the technical and financial feasibility of the Oosterweel Link, developing the design and the preparation of the tender.

The programme of the day was constructed quite variedly so that all participants found something to their liking. Among the issues discussed: the legislative framework surrounding water, with clarity on a number of practical and financial aspects; how to recover nutrients from process and wastewater; water production and spills:

constraints and opportunities for a regulatory framework; an upgrade of the soil water purification at Vesta; grey water and process water, a ready-made solution is still possible for your company; sustainable industrial sites and rainwater recycling at ‘Thor–park’; possible solutions to the current water problems of industry

in Flanders; how water recycling can lead to saving money; a brief look at water treatment of the future and ongoing resolute innovations. The items were interspersed with various cases.

The feedback from the participants showed that the variety of subjects was appreciated. The overview of current water technologies could also count on support. Just like the many cases that made the theory tangible. Thus a successful seminar!

‘Water for Industry’ seminar projects the futureOn Thursday 22 May, Grontmij organised a seminar around the topic of water and industry. Meeting place was the Port House (Havenhuis) in Antwerp. Around fifty participants including environmental coordinators, process managers, utility managers, HSE Managers, etc. gained an insight into the current trends and how to design an integrated water policy for their business.


G R O N T M I J N E W S

On October 14th, Grontmij brought together representatives of a small group of companies from the ferro and non-ferro industry. Among them were ArcelorMittal Gent, Umicore Hoboken, Nyrstar and Sadaci.

During this workshop the main question to find answers to was ‘How do industrial companies anticipate on challenges in a complex environment?’. Because today we are confronted with an environment where business is volatile, capital invest-ments are dynamic and budget assurance is mandatory. But even then, business drivers as Life Cycle Cost Management and Asset Management have to be dealt with.

Participants got an insight in current trends and how to manage them. They also discussed on topics like: how to optimize

project execution in order to meet business requirements as time, budget, quality, safety and how to bring added value? By aligning engineering, construction management and procurement. By securing the timely input of technology providers. By using best practices. By using new engineering and design technology.

Also on the programme: cost optimal design, engineering/design and construction, sustainability: heat grids and the possible use in the ferro and non-ferro industry, the use of 3D tech-nologies, the Oosterweel connection and a balanced price/quality of technology.

Please contact Gerard Verstappen on [email protected] for more information about the outcome of this workshop.

Structural specialists determined the dimensions and the operating procedure for the excavation of the pit. Surveyors from Grontmij are responsible for a continuous control measurement of the bed during the execution of the work. Environmental experts took care of the permits for the soil drainage and carried out the soil and mechanical investigation.

Gassco is relying on Grontmij for flawless project management and excellent communication with the various stakeholders such as the municipalities, the fire department, the port administration, forest management, TMVW (Inter-municipal Society of Flanders for Water Distribution), Infrabel and the police.



Grontmij is deploying expertise from all business lines and provides the IRMM with a real one-stop-shop via one account manager. Items addressed include: land surveys, laser scanning, Asset Information Management (AIM) and Building Information Management (BIM) expertise, (landscape) architecture, stability, HVAC, electricity, laboratory equipment, fire advice, EPB reporting, building acoustics, environmental consul-tancy and - permits, safety coordination, infrastructure, project management, ... The IRMM is also interested in certifying the new laboratory and existing buildings with the sustainability meters ‘BREEAM new build’ and ‘BREEAM in-use’.

In this article we focus on the energy policy plan, the site investigation and the under-ground and above-ground mapping.

Mapping utilities and functional analysis

Early in 2013, the collaboration between the IRMM and Grontmij started with a high technology Asset Information Management assignment for the site in Geel. IRMM has found it difficult to manage all the info on changes on the site correctly (Management of Changes). An overall picture was also missing.

In essence, this extensive task involves the collection, analysis and processing of data in a smart way throughout the entire infrastructure and the buildings and installations of the research campus. The end result should be an AIM system built up around 3D as-built models of the site. The

building and system administrators receive a modern tool for optimally managing the existing infrastructure, buildings and installations. The system also provides possibilities leading to Facility Management.

First phase: underground and surroundings In a first phase, land surveyors from Grontmij identified and listed the underground piping. Using conventional surveying techniques, they took an inventory of the above-ground assets such as fences, roads, location of buildings, all signs, ... From these initial activities, a topographical network was drawn up that serves as the basis for further data collection.

In order to obtain an as clear as possible picture of the underground, Grontmij set-up a well though through methodology. First, experts collected as much information as possible about the underground. This included the use of intake interviews with the site managers in order to lay functional relationships between buildings and via the analysis of existing documentation and plans.

On the basis of this information, a well-founded ‘suspicion’ grew of what types of piping (critical such as natural gas pipes, pipes for nuclear wastewater, high voltage power lines, non-critical, such as lighting cabling) lie where. Using the most appropriate technology - radio detection, ground-based radar, test trenches - the pipes were then detected and the exact locations thereof were determined. In this way Grontmij succeeded in sketching a correct image of the underground piping. The results of this analysis are further processed into a functional database, which includes

information about diameters, the logical structure of the network, ...

In early October 2014, the IRMM received a first 3D base map of the site with a functional analysis of the underground piping.

Second phase: buildings, installations and AIM systemIn the next phase, Grontmij processed buildings and building installations into 3D as-built models, and also carried out a functional analysis on these.

Using advanced 3D laser scans, Grontmij brings the existing state of the site into a virtual image. In combination with the existing plans this forms the ideal underlay in order to achieve consistent as-built 3D models. All modelled objects have a classification and unique identity, which allows for additional information to be extracted from the 3D models and to be linked into the AIM system. Thus, there is a relationship between each 3D model and the database.

Over the years, Grontmij has developed its own methodology for managing Asset Information. It was decided to fit this methodology within the IRMM’s available software platforms.

The IRMM obtains a tool wherein documents, plans, 3D models and functional logic of the installations are centralized, version management is possible, insight is provided into future enhancements, effects of changes may be estimated correctly, ...

Technologically sound, qualitative and completeThe IRMM has entrusted this strategic contract to Grontmij because of an outstand-ing offer, which was technologically sound, qualitative and complete. A significant boon for the IRMM is also that Grontmij offers solutions from within its own organization. Experts, including in buildings, infrastructure, land surveying, laser scanning, and asset

Mix of projects at the IRMM (Institute for Reference Materials and Measurements) of the European CommissionEarly in 2013 Grontmij started with the identification and mapping of the utilities on the IRMM site in Geel. At the same time, an energy policy plan was drawn up for the coming years. In the autumn of the same year Grontmij acquired a study assignment for the full implementation of an energy policy, a food laboratory and a multi-purpose building on the research campus. In their entirety, these assignments for the IRMM are taking five years to complete. Meanwhile, in the context of a framework contract, Grontmij is also working on all smaller assignments on the site.

information management gradually develop a management model for the building and system administrators of the IRMM. They gain a modern tool for optimally managing the existing infrastructure, buildings and installations. Facility Manage-ment is also possible at a later stage.

Progressive energy policy plan Grontmij is also taken up with inter-disciplinary work for the energy study and the business lines. The energy project starts with an analysis of the current gas and electricity consumption, a building physics study of the building shells and a control of the existing technical installations. Many disciplines are working together: energy consulting, feasibility screening from the wind team, thermographic analysis, brainstorming sessions with energy specialists, ... The straightforward account management monitors the contextualising of the energy study in the long-term vision and the overall concept of the IRMM site.

The objective of the energy study is twofold. Firstly put pressure on the energy costs and then work more sustainably in the long term. The IRMM has formulated this ambition into a development plan for the site. The study forms the basis of a broader energy policy plan that can grow with the future needs of the European research campus and wherein conventional and renewable energy sources are investigated and compared. Thanks to the study, there is now a clearly developed vision about how the site can be optimized in terms of energy taking into account the CAPEX and OPEX costs.

Heat recovery from a high temperature heat pumpOne of the key points of the study is the heat recovery on the cooling system of a particles accelerator on the IRMM site. Using a high temperature heat pump, a new and innovative technology, condenser heat from the cooling system is brought to a sufficiently high temperature to heat buildings. Another optimization consists of the connecting exist-ing boilers to central heat network of the site.
