April 2012www.sname.org/sname/mt VESSEL REPORT: AGBAMI FPSO VESSEL VESSEL REPORT The Agbami oileld, located in a water depth of 4,700 ft. (1,433 m), lies approximately 220 miles (352 km) southeast of Lagos and 70 miles (113 km) o shore Nigeria, in the central Niger Delta. e Agbami eld is a full subsea development consisting of an FPSO (oating production storage and ooading) vessel tied back to subsea wells via exible risers and static and dynamic umbilicals with gas injection and peripheral water injection. e FPSO vessel, when measured in terms of its total oil, gas, and water equipment capacity, is the largest FPSO in the world. e vessel weighs nearly 100,000 metric tons and has a processing capability of 250,000 barrels per day of oil and a storage capacity of 2.15 million barrels of oil. It is designed to handle 450 million standard cubic feet per day of natural gas and inject 450,000 barrels of water per day for reservoir pressure maintenance and improved oil recovery. e Agbami FPSO vessel is spread moored in place and does not have a propulsion system. e Agbami ooading system consists of a single- buoy mooring, located 1.2 miles (2 km) from the FPSO, and it is connected to the FPSO via two U-shaped steel ooading lines. e deepwater CALM buoy (23 m in diameter and weighing 1,050 tons) is installed alongside the Agbami FPSO. Oil ooading occurs approximately every four days in one million barrel parcels. e Agbami oileld came onstream in July 2008 and reached its peak production rate of 250,000 barrels per day in August 2009. e FPSO will be on location for more than 20 years. Star Deep Water Petroleum Limited, a Chevron Corporation affiliate, is the operator of the Agbami unit, which straddles oil mining leases 127 and 128. Other partners include Texaco Nigeria Outer Shelf Inc. (a Chevron aliate), Petroleo Brasileiro Nigeria Limited, Statoil Nigeria Limited, Famfa Oil Limited, and the Nigerian National Petroleum Corporation. e Agbami FPSO hull and topsides were fabricated by Daewoo Shipbuilding & Ma rine Engineering (DSME) in Okpo, South Korea. Key components of the FPSO vessel were also fabricated in Nigeria in the Nigerdock Nigeria PLC yard in Lagos and the Daewoo Nigeria Limited yard in Warri (Delta State). Nigerdock also fabricated the Agbami FPSO ooading buoy and suction piles. All the topside components fabricated in Nigeria were shipped to the DSME shipyard in South Korea, where they were integrated with the rest of the FPSO topsides. e Agbami FPSO vessel is classied by the American Bureau of Shipping (ABS).
