    1.4 Summary of Practical Training

    For the practical training, I was fortunate to get the opportunity to work at

    Germanischer Lloyd (GL) Noble Denton, a world class technical service provider for the

    oil and gas industry located in Kuala Lumpur. GL Noble Denton help to design, build,

    install and operate oil and gas onshore, maritime and offshore assets to ensure safety,

    sustainability and superior value. I was able to get hands-on view of what it was like to

    work in the oil and gas industry. My supervisors were more than willing to let me get

    involved and I was able to help them out on many different fronts. In addition to collect all

    relevant documents from client, scanning, photocopying and filling, I was taught how to

    use Galiom which is a combined asset integrity management and risk-based inspection

    and maintenance tool that can be used for any oil, gas, or petrochemical facility. I learned

    how to go through and taking a relevant data from process flow diagram (PFD), piping

    and instrumentation diagram (PNID), prepare minute of meeting and schedule planning

    and learned the overall process in oil and gas production. I learned how to select thickness

    measurement locations as well as utilize relevant information from the previous data to

    create the desired output. I set up and took part in meeting and meet the clients. I even got

    to take part in a project where I was assigned to select inspection test points for Balal Field

    Development Project. Moreover, I also involve with Murphy RBI Development Project

    2010 at Bintulu Onshore Receiving Facilities (BORF). At the end of the practical training,

    I was to present what I had learned and also come up with my personal opinions of the

    lessons that I learned during the practical training period. I presented my finished practical

    training in the form of a Power-Point presentation on the final day of my internship and it

    was received extremely well. I feel so lucky that I got this opportunity, especially at such a

    turbulent time in GL. I feel that I experienced a very unique point in the engineering field

    and that experience will make me well prepared for the real world that I am about to

    enter into. I greatly enjoyed and thrived in the fast-paced lifestyle that comes with this

    kind of job and the Kuala Lumpur environment where it was located. I really appreciate

    the people who have helped me to make this happen, and I wouldnt trade this practical

    training experience for anything.

    2.3 Asset Integrity Management Department

    Asset integrity is an asset has integrity when it performs as specified and is being

    operated and maintained as specified so that the combination of the likelihood of failure

    and the consequence of failure makes the risk to people, environment, assets and

    company reputation arising from its failure is as low as reasonably practicable. Plant

    integrity, safety, and reliability are major concerns to all plant operators and managers.

    The primary objective of AIM is to maintain the asset in a fit-for-service condition while

    extending its remaining life in the most reliable, safe, and cost-effective manner. AIM for

    an operating facility, is focused on the operating and technical integrity:

    1. Is the facility being operated within the design parameters?

    2. Is the facility being maintained as required within the time frame required?

    3. Is the facility being inspected as required with an effective, planned and written

    inspection scheme?

    In addition to regulatory and company requirements, operators of facilities and

    pipelines have the following business needs:

    1. Maximizing production

    2. Reducing lost income due to unplanned shutdown

    3. Optimizing inspection and maintenance costs.

    4. Maximizing asset value.

    5. Maintaining an auditable system

  • 7/27/2019 Final Report Practical

    14/59

    14

    2.3.1 Risk Based Inspection

    RBI is an approach to AIM which seeks to optimize inspection activities based on

    the likelihood and consequence of failure of components and systems. Using this

    methodology, inspection frequency is highest for the highest risk systems, and the

    interval between inspections if lengthened for those systems which have the lowest risk.

    This common-sense approach to inspection can significantly increase a plants on-stream

    availability.

    The primary objective in implementing an RBI programme is to produce an

    inspection strategy that clearly states:

    1. Which equipment needs to be inspected?

    2. The optimum interval between inspections.

    3. To use the right technique to detect the defects likely to develop for that a

    particular component.

    In a typical RBI, study will involve:

    1. Establish the qualitative or quantitative risk-ranking level of existing equipment,

    and determine the respective risk acceptance level based on standard industry

    practice and customer defined criteria.

    2. Assess the process operating parameters of CO2 mole fraction which impact

    production, mechanical integrity, and rates of corrosion or degradation.

    3. Review technical specifications and materials of construction, and provide gap

    analysis, recommendations, and turn-around prioritization.

  • 7/27/2019 Final Report Practical

    15/59

    15

    4. Assessment of risks associated with equipment degradation and corrosion rates

    using industry standards, such as API-580, API-579, and API-581.

    5. Determine remaining life for each component, and determine the appropriate

    inspection intervals.

    6. Specify the necessary inspection and maintenance tasks and intervals based on the

    risk ranking.

    2.3.2 Data Management Solution

    Even moderate scale Asset Integrity Management programmes produce massive

    quantities of data that must be effectively managed. Because the databases that result

    from AIM implementations can be so large, even simple data entry tasks can involve so

    many data points that they overwhelm even well staffed inspection departments.

    Furthermore, most standard corrosion monitoring software packages are limited in

    their ability to dynamically link data in the database to CAD drawings or field sketches.

    Also standard systems typically identify visual observations as open or closed, but do not

    effectively track status in terms of whether or not the remediation deadline is imminent or

    overdue.

    GL provides services which can address these common data management issues.

    GL applies an AIM approach with a sophisticated RBI and AIM tool (GALIOM). Galiom

    can be utilized as a one-off RBI equipment risk assessment software generating reports

    that identify the associated risk ranking of each piece of equipment, or as a fully

    integrated application.

  • 7/27/2019 Final Report Practical

    16/59

    16

    Galiom starts by establishing an asset hierarchy for the facility by breaking down

    each business unit into an area, complex, location, platform, functional group, tag, piece

    of equipment, feature or component and measuring or test points. The next step involves

    entering the design and operating data for each equipment tag into a database for the

    specific facility.

    Galiom calculates risk by multiplying the consequences of failure (CoF) by the

    probability of failure (PoF). CoF is assessed in four categories the consequences for

    people (safety), the environment, the asset (cost of damage or downtime) and the owner's

    or operator's reputation. PoF is appraised by considering factors such as the operation and

    design of an asset, corrosion, the impact on third parties, seismic activity, process

    stability and probability of failure modes.

    Galiom uses the CoF-PoF equation to identify the resultant risk and display it on a

    5x5 risk matrix. At the same time the asset hierarchy is colour-coded to display the level

    of risk for each piece of equipment, enabling the operator or owner to immediately

    identify the asset risk status. Risk within GALIOM is displayed on a 5 by 5 Matrix. The

    red colour areas are classed as Higher Risk, unacceptable risk, which should be addressed

    with some form of Mitigation Measure immediately. Risk increases from the Top Left to

    the Bottom Right. Ideally the aim is to have all equipment in the Green zones however;

    this is not realistic and is where an ALARP (As Low As Reasonably Practicable)

    principle is used.

    ALARP stands for As Low As Reasonably Practicable, and is a term often used in

    safety-critical and high-integrity systems. The ALARP principle is that the residual risk

    shall be as low as reasonably practicable.

    ForRiskto be ALARP it must be possible to demonstrate that the cost involved in

    reducing the risk further would be grossly disproportionate to the benefit gained. The

    ALARP principle arises from the fact that it would be possible to spend infinite time,

    effort and money attempting to reduce a risk to zero however it should not be understood

    as simply a quantitative measure of benefit against detriment. It is a judgement of the

    http://en.wikipedia.org/wiki/Riskhttp://en.wikipedia.org/wiki/Risk
  • 7/27/2019 Final Report Practical

    17/59

    17

    balance of risk and societal benefit. Risk being the multiplication of CoF and PoF can be

    displayed on a 5x5 matrix in table 1 below.

    Table 1: Risk Display

    GALIOM also uses the same color coding in the Asset Hierarchy to display Risk.

    Each piece of equipment is Risk Ranked and that ranking is rolled up to the highest level

    so that at a glance the Facility Risk can be seen. Just light a Traffic Light. Asset

    Hierarchy to display risk can be seen from figure 3 below:

    OVERALL PRACTICAL TRAINING

    3.1 Briefing

    In the first week of my practical training, I was introduced to all of the staff in the

    company. I also had a briefing session about company profile and about AIM department

    that I was attached to for my practical training.

  • 7/27/2019 Final Report Practical

    3.2 Assignment

    There are two assignments that had been given:

    1. Definition of AIM, RBI, MAWP and MAWT. The details can be viewed in

    Appendix I.

    2. Material Selection. The details can be viewed in Appendix II.

    3.3 Galiom Training

    I learned about Galiom software in term of understanding asset hierarchy at first.

    Functional groups, tag and test point need to be assigned. A part of that, I was taught to

    insert the data into Galiom. There are some functions that need to be understood first

    before we input any data that related with calculation. As an engineer, we need to

    understand why the selected data had been chosen and input to Galiom. Understanding

    the operating manual for the facilities is very important in order to understand the process

    flow diagram or any related drawings and documents. By doing that, we analyze and can

    detect any error in Galiom so the result of RBI can be accurate.

    3.4 Introduction of Oil and Gas Production

    Oil and gas industry is a massive industry. We need to know how oil and gas

    being produced in order to know the system and the functions for all of the equipments

    that are used in oil and gas industry. Wellhead, piping, separation, pump, compressor,

    christmas tree are some of the main components in oil and gas production.

    3.5 Meeting

    AIM department has weekly meetings. The purpose conducting such meeting is to

    update our tasks and to discuss any problem that need to be solved so we are on track on

    our project schedule. In the meeting, one person will be the chairman and another person

    will write the minutes of meeting. A sample minute of meeting can be viewed in

    Appendix III.

    3.5 Summary

    I gained a lot of experience in this practical training. The most important aspect

    that I have learned is I know what oil and gas industry is about. A lot of company are

    involved and depends on each other. From the geologist that find reservoir and the

    engineer that drills and build platform until the refinery to process oil, these whole

    processes needs a lot of man power. The summary of my practical training in 10 weeks

    can be seen from table 2 below:

    IOOC PROJECT

    4.1 Introduction

    After the victory of the Islamic Revolution of Iran, all partnership contracts with

    aforementioned companies were abolished at the decree or the Supreme Council of the

    Islamic Revolution in 1979, and a year later, the Iranian Offshore Oil Company (IOOC)

    was established by combining those companies. The objective underlying establishment

    of IOOC was to achieve an optimized production as well as safeguarding oil and gas

    reservoirs in the Persian Gulf area along with an increase in the production rate and

    prevention of oil and gas migration in the common fields, and in a word, to administer

    the entire oil and gas fields in the Persian Gulf where the American and European

    companies had previously carried out the oil activities.

  • 7/27/2019 Final Report Practical

    23/59

    23

    The Balal Oil Field is the one of field in the Persian Gulf. The Balal field is a

    dome structure analogous to a circle with a diameter of 2.5 km. The area of the field, at

    top of Hith-Arab formation, is about 16 km2. The main reservoir of this field is Arab

    formation composed of carbonate, and subdivided into 7 layers. The secondary structures

    in this field are Khatiyah, Shuaiba and Khuf respectively. The average depth of reservoir

    is about 6000 ft containing a light and relatively good quality crude oil with API of 44

    degrees. The ultimate recoverable oil reserve is estimated to be 117 MMSTB which will

    be achieved by daily water injection rate of 50000 BWPD and considering the original oil

    in place of 293 million barrels, the recovery factor will be 40% for a period of 14 years

    which is envisaged to be a very good recovery factor.

    4.2 Project Description

    Our team has to conduct AIM and RBI for Balal Offshore Oil Complex for IOOC.

    The scope of work shall be done in Balals facilities specified below:

    1. One wellhead platform

    4.6 Project Schedule

    In order to complete all of the tasks in this project on time, scheduling all of the

    tasks are necessary. This project schedule is also required by the clients to see theprogress of our work. Project schedule can be seen from figure 7 below:

    4.7 Thickness Measurement Locations

    My scope of work is to develop the next inspection due date. In order to do that,

    we need to identify thickness measurement locations (TMLs). TMLs are specific areas

    along the piping circuit where inspections are to be made. The nature of the TML varies

    according to its location in the piping system. For selection of TMLs, we consider the

    potential for localized corrosion and service-specific corrosion. Each piping system need

    to be monitored by taking thickness measurements at TMLs. Based on piping inspection

    code, piping circuit with high potential consequences if failure should occur and those

    subject to higher corrosion rates or localized corrosion will normally have more TMLs

    and be monitored more frequently. In order to develop next inspection due date, the

    interval between piping inspections shall be established and maintained using corrosion

    rate, remaining life calculations, piping service classification, applicable jurisdictional

    requirements, judgment of the inspector, the piping engineer, the piping engineer

    supervisor, or a corrosion specialist, based on operating conditions, previous inspection

    history, current inspection results, and conditions that may warrant supplemental

    inspections.

    The minimum thickness at each TML can be located by ultrasonic scanning or

    radiography. The thinnest reading or an average of several measurements readings taken

    within the area of a test point need to be recorded and used to calculate corrosion rates,

    remaining life, and the next inspection date. TMLs need to be marked on inspection

    drawings and on the piping system to allow repetitive measurements at the same TMLs.

    This recording procedure provides data for more accurate corrosion rate determination.

    We decide that more TMLs need to be selected for piping system with any of the

    following characteristics:

    1. Higher potential for creating a safety or environmental emergency in the event of

    a leak.

    2. Higher expected or experienced corrosion rates.

    3. Higher potential for localized corrosion

    4. More complexity in terms of fittings, branches, deadlegs, injection points, and

    other similar items.

    5. Higher potential for corrosion under insulation (CUI).

  • 7/27/2019 Final Report Practical

    30/59

    30

    Fewer TMLs can be selected for piping systems with any of the following three

    characteristics:

    1. Low potential for creating a safety or environmental emergency in the event of a

    leak.

    2. Relatively noncorrosive piping systems.

    3. Long, straight-run piping systems.

    TMLs can be eliminated for piping system with either of the following two

    characteristics:

    1. Extremely low potential for creating a safety or environmental emergency in the

    event of a leak.

    2. Noncorrosive systems, as demonstrated by history or similar service, and system

    not subject to changes that could cause corrosion.

    Based on design code; we can calculate MAWP and MAWT. All of the

    calculation will be calculated by Galiom which is the software for asset integrity

    management. The data for design pressure, design temperature, quality factor, design code

    and nominal wall thickness are mandatory for any tag that we want to select TML. The

    main objective for all of this process is to know the remaining life. This remaining life can

    be known by knowing the remaining wall thickness, MAWT, and corrosion rate. The datacan be seen from figure 7 and mark-up drawing from figure 8 below:

    CHAPTER 5

    CONCLUSION

    5.1 Conclusion

    This internship was very fruitful to me because I learn new concepts and new

    ways of working. It was interesting to see how business works, how it is vital to spare

    money and to make strategic choices. Moreover, I know the importance of inspection at

    facilities. I was also given opportunity to involve with projects.

    Concerning the project that I was involved with, it was interesting to discover the

    concepts that I was taught in my engineering school such as statics, solid of mechanics,

    material engineering and component design. The work in itself was also interesting in

    different point of views. Handling the PFD, PNID and isometric drawing allows me to

    learn more in oil and gas field. Also, another interesting part was that I started from

    scratch. Indeed, I have to mark-up drawings to find critical location for corrosion.

    Moreover, I learned to use Galiom to do analysis. Even though that was

    something new for me, I was able use this software and could understand the functions of

  • 7/27/2019 Final Report Practical

    34/59

    34

    this software. Thanks to the staff of AIM department that were willing to teach me the

    steps to understand this software.

    This internship was a great experience. It was a real pleasure to work with GL.

    Carrying out this internship in multi-national company allows me to experience different

    culture and faced the problem of living and working entirely in a non-native language,

    English. I also had the opportunity to meet interesting people in and out of the office such

    as engineer, software engineer, as well as other people not connected with science.

    5.2 Recommendation

    I was grateful to be able to gain internship in GL. However there is one

    recommendation to make the internship program more challenging and more organized.

    One suggestion to make the project more organized is to plan for the whole internship

    programme for the interns. The interns can be more focus towards the assignment that

    had given rather than just accepting any assignment.

    4. By knowing plant life cycle, we can manage the integrity of an oil & gas facility that needs to

    consider the fundamental performance of materials in the oilfield environment in addition to

    the economics of the oil industry and local operations and acceptable.

    Answer

    Asset Integrity Management

    An asset has integrity when it performs as specified and is being operated and maintained as specified

    so that the Risk to People, Environment, Assets and Company Reputation arising from its failure

    is As Low As Reasonably Practicable.

    Risk Based Inspection

    The application of Risk Analysis principles to develop and manage inspection programs for plant

    equipment.

    Risk is the potential consequence based on a specific Hazard or Danger driven by its individual

    probability of occurrence.

    Minimum allowable wall thickness

    The minimum required thickness, including mechanical, corrosion, and erosion allowances for wall

    thickness.

    Wall Thickness is a value that indicates the thickness of the tubing wall. It may remain unchanged as the

    outside diameter and inner diameter change.

    39

    Remaining Life

    The prediction of the occurrence of failure events for process equipment based on a clear definition of

    load history, damage accumulated to date, projected operations and material properties.

    Maximum Allowable Working Pressure

    A maximum gauge pressure permissible by an equipment/device (at coincident temperature specified

    for that pressure) and is governed by code i.e. ASME, JIS,GB, etc.

    Formula

    Straight Pipe according to B31.3

    tm = t + c

    tm = minimum required thickness, including mechanical, corrosion, and erosion

    allowance

    t = pressure design thickness, as calculated for internal pressure or as

    determined for external pressure

  • 7/27/2019 Final Report Practical

    40/59

    40

    c = the sum of the mechanical allowances (thread or groove path) plus

    corrosion and erosion allowances. For threaded components, the nominal

    thread depth (dimension h of ASME B1.20.1, or equivalent) shall apply.

    For machined surfaces or grooves where the tolerance is not specified, the

    tolerance shall be assumed to be 0.5 mm in addition to the specified depth

    of the cut.

    Straight Pipe Under Internal Pressure

    For t < D/6, the internal pressure design thickness for straight pipe shall be not less than that calculated

    in these equations:

    P = internal design gage pressure

  • 7/27/2019 Final Report Practical

    41/59

    41

    d = inside diameter of pipe. For pressure design calculations, the inside

    diameter of the pipe is the maximum value allowable under the purchase

    specification.

    D = outside diameter of pipe as listed in tables of standards or specifications

    or as measured.

    E = quality factor from Table A-1A or A-1B (pages 231&232)

    S = stress value for material from Table A-1 (pages 182)

    For t D/6 or for P/SE > 0.385, calculation of pressure design thickness for straight pipe requires special

    consideration of factors such as theory of failure, effects of fatigue, and thermal stress.

    Y = coefficient from Table 304.1.1, valid for t < D/6 and for materials shown.

    The value of Y may be interpolated for intermediate temperatures.

    For t D/6,

    Project Background

    The Balal Field is located in the Iranian Sector of the Persian Gulf, at approximately 100 km to

    the south-west (SW) of lavan island at a geographic location approximately 2619 N,

    5232 E, in a water depth of approximately 66 m.

    Introduction

    The Balal Field is intended to drill 5 wells to produce from this interval at an initial total

    production rate of 40,000 BOPD. Water injection will ultimately be required for pressure

    maintenance and 5 injection are planned. The key design production rate is as follows:

    Maximum crude oil production : 40,000 STBOPD

    Maximum produced water rate : 33,000 BWPD

    Maximum injection water rate : 50,000 BWPD Maximum total produced fluid rate : 45,000 BFPD

    The development plan is based on a central complex comprising a combined Process and Living

    Quarters (PLQ) platform, a single 16 slot drilling/wellhead platform (WHP) and a flare

    tower, all bridge linked.
