3 IMEC INTRODUCTION Established in IMEC is licensed under PETRONAS SWEC code system. Approved under Petronas Block BAR MWS Policy. Marine Assurance & Engineering Support Services. ISO 9001:2008 certified company.

4 KEY LOCATIONS Kuala Lumpur, Jakarta & Singapore Aberdeen

5 INTRODUCTION Trends in Floating Production Market. Advantages of Floating Production Facilities. Factors Affecting Life Extension & Redeployment. Life Extension & Redeployment Options: Same Field. Different Operating Area. Long/short term lay-up.

6 CRUDE ASSAY & PRODUCTION PROFILE Crude oil composition, gas/oil/water ratios, production volumes and duration. Can all have a Significant Impact on the functional specification (topsides weight, power requirements, field life, corrosion protection etc.). No such thing as a standard FPSO certain modifications required for each new production application.

7 TECHNICAL ASSESSMENT Essential that basis of design is clearly understood at the outset. Hull Elements. Production Facilities. Mooring System.

8 ASSET INTEGRITY Depends greatly on how the unit has been operated. Fatigue Assessment. Rotating Equipment & Pipelines. Thickness Gauging. Surveys.

9 INTERFACE STRUCTURES, NOISE & VIBRATION Interface between Equipment Modules and Hull Structure. Important due to Significant Topsides Size and Weight. Stringent Noise Limits now Apply to Accommodation Area.

10 HARMFUL SUBSTANCES & COLLISION PROTECTION Insulation such as asbestos are still present on many units. Decision to encapsulate or remove. Asbestos Management Plan. Adoption of high standards of collision protection. Use of Sponsoons, Collision Frames & Internal Strengthening on Side Shell.

11 PERFORMANCE STANDARDS, REGULATORY COMPLAINCE Challenges such as Deck Space Limitation, Power Availability. Changes to Process Performance Requirements. Regulatory Changes Specific to Floating Units.

12 PROJECT EXECUTION STRATEGY Critical towards the success of any life extension / redeployment project. Will influence the scopes that may be achieved, methodology and operational issues. Factors such as statutory inspections, class survey cycles and material availability are to be considered. Effective Planning minimizes disconnection time and loss of production.

13 TRANSPORTATION ASPECTS The Floating Unit will most likely be towed to the intended location (unless it has its own propulsion system). Attention to structural loading as towing period may undergo the most severe loading condition. Manned or Unmanned. Weather Impact on tug efficiency and effective bollard pull.

14 LONG TERM LAY-UP ISSUES Safety, Security and Assurance for Units Removed From Location. Exposure such as Breaking Free of Mooring. Fire. Watertight Integrity. Collision. Frequent follow up and inspection as opposed to lock and leave. Seek same level of support engineering & documentation as other phases of asset lifecycle.

15 CONTRACTUAL CONSIDERATIONS Early Termination of FPSO lease contracts has been an area of potential legal dispute. Termination for cause or convenience. Independent Reviews conducted in advance can save time and money compared to lengthy arbitration processes. Decisions on redeployment are key areas of underwriter exposure.

16 CASE STUDY (APOLLO SPIRIT) Unique Construction, Modification & Operating History. Fast tracked FSO Life Extension to increase design life by 6 years. Actual structural details were different from drawings in several locations, presenting an engineering challenge. A total of 260 tonnes of Steel replaced at Remontowa Shipyard, Poland. An example of how early preparation is key.

17 CASE STUDY (NAUTICA MUAR DECOMMISSIONING) Engineering Support towards Decommissioning of Nautica Muar FSU & redeployment of Mampu 1 FSO. Limited storage capacity main driver for decommissioning. Currently being executed and various types of engineering analysis and assessments were required before the project could commence.

18 CONCLUSIONS Drivers for success include: Proper Scope Management. Safety & Risk Management. Firm Communication Protocols. Effective Management of Change. Clear Definition at the outset. Collaboration & Communication. Floating Units have the right level of flexibility. Effective Redeployment of units can be more attractive than new build units provided that the associated risks are identified and managed. Critical to ensure that the marine assurance aspects are adequately covered.
