Objective-Offshore & Energy Scandinavia AB Weight impact if we change from CAT to STX

Objective-Offshore & Energy Scandinavia AB It is important to know the maintenances schedule for both engines in order to have an idea of how many times we could require parts and labor. The comparison for both schedules is only for one DG. Then, we should multiply by at least three since the philosophy is to run three DGs. Maintenance schedule for both DGs

Objective-Offshore & Energy Scandinavia AB

The maintenance rotation for CATERPILLAR is higher even though we consider a friendly environment. However, due to CATERPILLARs lower power rating, their maintenance schedule rotation will be higher (worse) since will be necessary to run more generators to fulfill power demand, and thus, this means more cost.

Objective-Offshore & Energy Scandinavia AB II. A60 Insulation to Main Deck (H307-YCRO-OJV-VOP-002)

Objective-Offshore & Energy Scandinavia AB Reason for Variation Area suggested from Yard for temporary refuge is within class requirement. In order to get a more functional temporary refuge, it is suggested to enlarge that area since our rig will host 600 persons. Enlarged area will incorporate facilities as toilets, water/food and emergency hospital. Besides, the enlarged area, will be suitable to refuge 600 persons. This change give the rig a total different platform in discussion with potential clients from the safety aspect, which could add a value in the negotiation.

Objective-Offshore & Energy Scandinavia AB Actual area (A60) is 550 m

Objective-Offshore & Energy Scandinavia AB Suggested area (A60) 3,000 m

Objective-Offshore & Energy Scandinavia AB Suggested refuge area for client (A60) 1,400 m

Objective-Offshore & Energy Scandinavia AB III. Helideck Foam System (H307-YCRO-OJV-VOP-003)

Objective-Offshore & Energy Scandinavia AB Details According to the Specification, the helideck foam system should be FMS type which uses monitor to protect helideck area. We see this system have some disadvantages and we count them: Even though people is trained to take a position as fire fighter for helidecks, there is the inconvenient of fear of fire, and there is no training for that. This might do that fire fighters run away from the scenario. One more thing to be taken into account, is that due to stress, orders to firefighters, during the monitors operation can be misunderstood, and thus spraying when jet is needed or viceverse. A possibility exist that firefighters can be harmed by the fire or stress. The wind stream is not constant from one direction. This can lead to not cover with the monitors an area that could be needing put out the fire.

Objective-Offshore & Energy Scandinavia AB 30 Proposal Pop-up system has the next advantages: The system is a compact DIFFS with pop-up nozzles and skid designed to mix foam concentrate in to fire water carrying foam tank and proportioner. The system proportions an exact rate of foam concentrate directly to fire water line close to the nozzles only using some of the energy in the water. This is added value to the client. Involves less persons into firefighting activity, reducing the probability of more casualties. Monitors can be taken away and it is accepted by Brazilian Navy Directorate of Ports and Coasts through its Maritime Authority Standards for Approval of Helidecks Installed on Vessels and Offshore Platforms NORMAM-27/DPC, CHAPTER 7. FIRE PREVENTION, FIREFIGHTING AND RESCUE (34 of 94).

IV. GRE Piping (H307-YCRO-OJV-VOP-005)

Objective-Offshore & Energy Scandinavia AB GRE Introduction This study is based on ABS MODU rules 2015 which is the applied for our project CR600, thus; The technical source is ABS Rules for MODU and the result of this study is to be applicable to systems for our project.

Objective-Offshore & Energy Scandinavia AB GRE Description According to ABS (MODU Rules 2015) plastic means both thermoplastic and thermosetting plastic materials, with or without reinforcement, such as polyvinyl chloride (PVC) and fiber reinforced plastics (FRP). Plastic includes synthetic rubber and materials of similar thermo/mechanical properties. These plastic pipes can be used for systems listed in the table 2. In table 3 you will find the typical standards recognized by ABS and applicable to all systems. There are special requirements that are to be applied to piping, depending on location and/or service, and this can be seen in table 4.

Objective-Offshore & Energy Scandinavia AB Systems which we propose to change piping are: YCRO354-L-722-XB-001 P&ID-Main Engine & AT Cooling Water System YCRO354-L-722-XB-002 P&ID-Thruster Cooling Water System YCRO354-L-722-XB-003 P&ID-Utility Cooling Water System The roughly distance of piping to change is 373 m and they are transporting sea water. GRE Description

GRE Technical features Weight difference

Objective-Offshore & Energy Scandinavia AB GRE Technical features Resistance The main reason industries are turning to GRE piping is its resistance to corrosion. Among the liquids this piping is bearing, we find: potable water, sea water, chilled water, and other several chemicals.

Objective-Offshore & Energy Scandinavia AB GRE Technical features Handling Application: Water Distribution, Industrial, Municipal & Infrastructure, Desalination & Power, Oil & Gas, Petrochemical & Marine Application. Compared to steel pipes, GRE pipes are easier to handle and operate. Especially when we thing in fittings and jointing the piping system. Steel pipes require for all fittings and joints to be welded, then, this is an important resource consuming activity, and thus adding cost. Among the activities we have cutting, surface preparation, grinding and cleanliness. Steel pipes cannot be repaired, they need to be replaced and immediately, even the leak or damage is minor.

Objective-Offshore & Energy Scandinavia AB Regarding GRE, when damage is minor, normally can be repaired quickly and easily. Seal-lock-joint is a connection with an O-ring and locking key; its maximum pressure is 70 bar. This minimize the use of fittings. It is necessary to apply a small lay of grease and connect. You can see the difference: GRE Technical features Handling

Objective-Offshore & Energy Scandinavia AB GRE Conclusion The first conclusion is that plastic pipes are accepted to be used widely, not only offshore but onshore too. There are several case studies about why several different industries have turned to GRE pipes. Municipalities have invested to change their old piping to GRE. The main reasons, apart of added value, are :

Objective-Offshore & Energy Scandinavia AB GRE Conclusion GRE piping exhibits exceptional highly resistance to corrosive materials. In addition, they are tough, flexible and light, as well as cheaper in the long run in comparison with steel pipes. Moreover, its easier handling compared to not only steel pipes makes less resources to be necessary. These and other properties of high quality engineered thermoplastic, make savings can be counted since the initial investment, and afterward, maintenance costs are substantially indisputable. All the above means added value.

Objective-Offshore & Energy Scandinavia AB V. Deck Crane (H307-YCRO-OJV-VOP-006)

Objective-Offshore & Energy Scandinavia AB 45 CR 600 VOP No: H307-YCRO-OJV-VOP-006, Variation to deck Crane. OJV has proposed to upgrade both deck cranes from 60MT each to 75MT and 150MT. This is based on the configuration of other platforms that are new or will be delivered in the next few years. Also OJV has the opinion that the current cranes are marginal for the intended service under realistic offshore operation, Which consists of lifts from other vessels and fixed platforms. Another onboard operation is to remove the whole gangway in order to add or remove pedestal extensions. This to adjust the gangway height to fit the vessel or platform we will connect with. This requires a higher capacity crane and without this crane we need to rent a offshore heavy lift crane for this operation. Additional Cost.

Objective-Offshore & Energy Scandinavia AB 47 Comparison between the current TSC 60MT crane and Liebherr 75MT and 150MT. Lifting is either: Onboard Lift i.e. You lift from your own platform and land the load on your own platform. Offboard Lift i.e. You lift from or to another vessel or Fixed platform For both lifts the waves will induce dynamic loads that will reduce the actual lifting capacity. The sea state is described with the Significant Wave Height, Hs. Hs=1.5m is a normal sea state for offshore lifting, but is can be carried out in worse weather with further reduction of the lifting capacity. For the TSC crane Onboard Lift is defined for Hs 1.5 and 2.5m and Offboard Lift for Hs 1.5 and 2.5m. For the Liebherr Cranes Onboard Lift at Hs 2.0m and Offboard Lift at Hs 1.5, 2.0, 2.5 and 3.0m

Objective-Offshore & Energy Scandinavia AB 48 From the tables below the capacities can be compared. The Hs are not the same for the two makes but it gives clear indications. If we focus on the Offboard Lift at Hs 1.5m we can see the summary below. (The full Excel sheet is attached as a separate document.) Main hook: The TSC crane at 18m radius has a capacity of 33.5MT, Liebherr 75 has 60.0MT and the Liebherr 150 has 85.0MT but at a worse sea state of Hs 2.0m At 38.6m the maximum radius of TSC its capacity is down to 12.8MT. At 51.0m the max radius of Liebherr 75 its capacity is down to 19MT. At 60.0m the max radius of Liebherr 150 its capacity is down to 18.7MT, but in a worse sea state of Hs 2.0m. Auxiliary hook: The TSC crane at 38.6m has 10.0MT capacity. The Liebherr 75 at 56.0m has 15.0MT capacity. The Liebherr 150 at 65.6m has 25.0MT at Hs 1.0m, 22.6MT at Hs 2.5m and 16.5MT at Hs 3.0m

Liebherr has indicated costs for the Liebherr 75 and Liebherr 150 and the freight to the yard at EURO 2.6+3.8+0.6=7.0 million. This is about 7.85 million USD. The shipyard has quoted 7.833 million USD for the VOP No: H307-YCRO-OJV-VOP-006.

Objective-Offshore & Energy Scandinavia AB VI. MGPS (No final information from Yard)

Objective-Offshore & Energy Scandinavia AB MGPS Reasons for change ANNEX I. I-ET-000. ANEXO I - GENERAL TECHNICAL DESCRIPTION, section 3.1 This section describes that The Unit shall have an ionized chlorine shall be injected at the inlet of the seawater lift system, to avoid fouling or marine growth. Chlorine is a well-known toxicant. It has been shown that 0.2 to 0.5 PPM of continuous chlorination will prevent all marine fouling in time. Higher than 0.5 PPM might produce the corrosion of the metallic piping, and other equipments.

Objective-Offshore & Energy Scandinavia AB MGPS Other impacts Cooling piping. Chlorine is corrosive and will be necessary to change pipes in shorter time. Water makers. Chlorine will reduce the lifespan of membranes. This will lead us to install additional filters in order to lower down the chlorine level. All above will add costs during the rigs lifetime.

Objective-Offshore & Energy Scandinavia AB MGPS Assumptions and notes According to some investigations, Petrobras does not have any preference as soon as they are in compliance with international standards. Beside this, some fiscals assure that ICAF is the preferred. More man hours spent for maintenance as well as more allocated maintenance, since this kind of method requires continuous monitoring and control. Both are approved for using according to IMO. Copper is the most effective product to prevent barnacles and mussles from settling in cooling water inlets or box coolers.

Objective-Offshore & Energy Scandinavia AB MGPS Comments Now a days ships are equipped with MGPS. MGPS stands for Marine Growth Prevention System. Its basic principle is based on the ICCP system. Direct Current is applied to the anodes to emit ions in the environment in order to change it into an unfavorable condition for the growth of fouling organism. Normally Copper Anode and Aluminum anodes are used. Changing to ICAF will benefit more parties since will require not piping, less maintenance, no man hours practically, less damages to equipments, and thus, less cost in the long run save money.

Objective-Offshore & Energy Scandinavia AB MGPS Comments ICAF is friendlier with environment. Benefits is, then, for all parties. There is no final cost from shipyard for our proposal, however, a refund is expected due to the lower cost of this system.

Objective-Offshore & Energy Scandinavia AB VII. WI-FI (No final information from Yard)

Objective-Offshore & Energy Scandinavia AB 61 As known to all, the advantage of WI-FI is to make people use portable electronic devices freely, and is independent of fixed LAN connection for an appointed place. On purpose to give more comfort and convenience for client/crew live on platforms, we advise to use WI-FI in cabins and public area of accommodation. This is a hotel facility and the client are resting at our platform, we need to make them satisfied on it. YCRO to evaluate the possibility to install WI-FI on platform. And the reply from YCRO is no problem. YCRO will summit TP and VOR.

Objective-Offshore & Energy Scandinavia AB 62 VIII. Mooring (No final information from Yard)

Objective-Offshore & Energy Scandinavia AB 63 CR600 MOORING SYSTEM The CR600 platform as proposed from CIMC Raffles has no mooring system installed. The yard claims it is not required by ABS for a DP3 unit. ABS can accept that you have no anchors provided that the platform is assisted by tugs when in transit near/within harbour, coast or busy waters. This is very expensive and in addition Oil Companies will require that you can emergency anchor in case you lose power when you are along side a production unit or within an oilfield with numerous platforms. As an Owner you must be aware of that many areas where there are oilfields have shallow coasts and harbours are not very large. Most harbours will refuse a platform to moor alongside a quay, you will block the harbour. Therefore you anchor with 4 or 8 anchors in a bay or in a port area if there are room enough.

Objective-Offshore & Energy Scandinavia AB All platforms recently delivered or under construction have anchors. 8 point mooring is most common, some has 10 point mooring for work in the North Sea. There are a few units with 4 anchors to be able to store the platforms between contracts. NAMEOWNERFLAGCLASSBEDSDECK AREAVDLCRANESDPMOORING AXIS NOVA, AXIA XX, plus 1 opt.

Objective-Offshore & Energy Scandinavia AB OJV has requested a proposal based on an eight point mooring design. The platform will be prepared for this. Thus there will at each corner of the platform be an anchor rack that can store two anchors. The columns will be reinforced and prepared for installation of two fair leads. The deck will be prepared and strengthen for installation of two winches with one power unit. We have asked for a proposal to have the platform delivered with four sets of winches, fairleads and anchors. The system can easily in the future if needed be expanded to eight point mooring by adding the missing equipment. The mooring system will be designed for a water depth of 200m using the installed mooring system. The intended use is to be able to anchor and store the platform between contracts or during a major maintenance job. With a complete 8 point mooring system you can work alongside a platform on anchor with the option of POSMOOR DP assisted mooring to further enhance the performance For deeper water depths you can connect your anchor wires connect to prelaid anchor system with chain. We are expecting a proposal from CIMC Raffles in the near future.
