3 FPSO Hulls: Conversions and New Builds-Outline Situations favoring Conversion or New Build Background Historical Composition of FPSO Fleet Evolution of FPSOs : Marginal to Full Field Developments New Challenges for FPSOs Tanker vs. Offshore Specs/ Functional vs. Prescriptive Specs Comparison: Conversion contrasted with Newbuild New Build options Custom New Build New Build Conversion Schedule Cost There is no single solution that fits all 3

4 Historical Composition of the FPSO Fleet Year Future Number of Operating FPSO s More unless some new technology Conversions 62% 62% 70% Fewer? Newbuilds 38% 38% 30% More? Contractor-Operated - 53% 52% No Change? Contractor-Owned - 53% 52% Fewer because of IFRS Field Operator Owned / Operated Field Operator Owned/ Contractor Operated - 47% 48% More because of IFRS - - Very Few May increase Note: IFRS: International Financial Reporting Standards adopted by 127 countries require long term operating leases to be on book 4

5 Historical Factors Favoring Conversion or Newbuild Consideration/ Driver Conversion Newbuild Process Capacity Up to 120M bopd Up to 250M bopd Schedule Cost Commercial Flexibility Quality/Reliability/ Maintainability HSSE (During Fabrication and Operations) Life on-site Shorter (10-15 years) years Finance Operating Lease attractive to smaller Operators Major Oil Company Financial Resources Tanker market, shipyard backlog and equipment delivery schedule changes are frequent and radical, and can alter these factors. There is no single solution that fits all cases, all of the time. 5

6 Recent Changes Favoring Newbuilds Tanker-based Newbuild Hulls The shipbuilding boom is over; conventional shipyards are hungry for work. Shipyard engineering is no longer a limiting resource. Dry dock slots are no longer a schedule driver; contract-to-hull delivery times are back to 24 months. Marine material and equipment delivery times have returned to normal. Availability of national financing (Export Credit Agencies/subsidies to shipyards) Custom-designed Newbuild Hulls All of the above. Increased production facilities capacity and complexity are pushing the limit of deck space on standard double-hull VLCC designs, typically 320m LBPx 58-60m Beam. There are only two ULCC s left in the tanker fleet. 6

7 Changes& Challenges in the FPSO Business During past 26 years Marginal to Full Field Development (1 of 3) FPSO Application Marginal Reservoirs, Early Production Testing Moderate size reservoirs Larger & Major reservoirs BOPD 20-40, , ,000 Storage Capacity / Dwt 0.5 mm bbls / 80,000 dwt 1 mm bbls / 150,000 dwt 2 mmbbls / 320,000 dwt* Design life on site 1-5 years 5-10 years years Water depth Offloading Frequency Accommodations POB Shallow, Less than 100 m * Present limit for the double hull VLCC tanker fleet Less than 300m Up to 2500 m days days 5-10 days to 140 or more 7

8 Changes & Challenges in the FPSO Business During past 26 years Vessel Availability (2 of 3) Newbuild Tanker Yard Hull Capacity Repair yard Capacity Used tanker availability Local Content Requirements Hull Delivery 24 months after contract, standard VLCC Available and low cost Plentiful 10 year old SH 1970 s robust mild steel or minimal HTS hulls Not an issue Hull Delivery 24 months after contract, standard VLCC Available Mostly ship repairs. Diminishing supply of aging 1970 s designs. Plentiful 1980 s / 90 s optimized HTS-rich SH available through end of 2010 Not a major issue (Brazil 6%-7%) Hull Delivery 4 years after order 2007/ 2010 but now 24 months Limited until recentlyrepair facilities took on rig & small ship building Plentiful supply of double hull motor tankers tanker market currently depressed Requirements are increasing (Brazil 70%) 8

9 Changes and Challenges for FPSOs 3 of 3 Changing Market Demand Conditions Impact on Material and Equipment Deliveries 16 months 2008/2009 for large rotating equipment Turbines went from 40 week delivery to 52+ weeks at peak Titanium Exchangers from 22 weeks to 40 weeks during peak Turrets: 18 months (bearings, swivels, valves, fabrication) On-Vessel spread-moored equipment: 14 months peak More Complex Topsides Equipment on FPSOs (= More Engineering & Equipment) Expanded production capacity Sulfate Removal for SW injection Strict and high volume produced water treatment H2S removal High CO2 Acid Gas Treatment LPG or condensate recovery Gas Compression for injection and / or export Turret Swivel materials and pressures Export booster pumps for spread moor-remote calm configuration Flow assurance for deep water ( diesel displacement, hot oil heating, Methanol) Application of prescriptive and offshore specifications to hull Shrinking sources of financing post 2008 / higher equity requirements by lenders 9

10 Functional vs. Prescriptive Marine vs. Offshore Specification With Functional Spec, FPSO Contractors are free to Offer Standardized In-House Design With Modifications Design Based on Industry Standards ASME /ANSI, API, IEC, IMO, NACE, NFPA, Class, etc Equipment suppliers with which FPSO Contractor has long term relationships and established specs, T s and C s Marine Specs for Hull based on Flag, Solas, Marpol, Class, IACS, & OCIMF : Minimum impact on shipbuilder Equipment, piping systems tailored to marine applications Class FPSO rules are well developed for hull structure Impact of Specs on Schedule months for a functional/marine spec compared to months best case with a Prescriptive & Offshore oriented hull spec (durations are contract to ready-for-first-oil) because: - Impact on engineering - Impact on equipment supply time - Impact on construction time - Change=Stress 10

11 Newbuild Hull Options 2010 Study Study initiated because: Conventional newbuild shipyards not interested in one-off custom hulls too busy with conventional ships. Newbuild Conversion Concept was to minimize impact changes to yard standard practice Utilize standard tanker hull design Minimize impact on shipyard engineering Minimize impact on shipyard supply chain Minimize impact on highly automated fabrication 11

12 Newbuild Option Hull Type Experienced Contractors Newbuild Hull Options-2010 Study Custom Design (2004) Custom design, double-side barge, single-bottom Few who can do both hull & topsides Tanker Newbuild Conversion (Intercept or New Contract) Shipyard standard, double-hull VLCC Many Japan, Korea, China Tanker only Accommodations (pob) 140 or more 30 Tanker/140 FPSO Propulsion None Yes, possibly reduced horsepower Hull Piping Standards Offshore/ANSI Marine standard (JIS/KIS) Hull Delivery after contract 24 months 24 months FPSO Delivery (Contract-to-Sail away from topsides integration yard) 36 months months FPSO Hull Cost Twice Standard VLCC + 20% (estimate) Newbuild Conversion Hull Cost estimated based on 2010 Market Price of standard VLCC plus 2010 bid conversion costs. 12
