Project Profile
Value: US$1,080 million
Location: Deepwater of Nigeria
Water Depth: 1,700 m / 5,610 ft
Start-up Year: March 2009
Discovered in 2000, the Akpo field is located in ultra deepwater of Nigeria. Situated on OML 130 approximately 124 miles (200 kilometres) from Port Harcourt, Akpo\'s water depths range from 3,609 to 5,577 feet (1,100 to 1,700 metres). A gas and condensate field, Akpo is operated by Total, holding a 24% interest in the project. Other participants in the license include CNOOC with 45% interest, Petrobras with 16%, NNPC with 10% and Sapetro with 5%.
Beginning in 2005, the Akpo field development project includes 44 wells -- 22 production wells, 20 water injection wells and two gas injection -- of which 22 have already been drilled, tied-back to an FPSO. The subsea infrastructure consists of 110 kilometres of a complex array of high pressure-high temperature subsea flowlines connected by steel catenary risers to an FPSO.
In May 2005, Cameron was awarded the US$340 million contract for the subsea systems on the field, including 44 subsea wells, xmas trees and manifolds. Cameron then subcontracted Roxar to provide the multiphase flow metres for the development, as well as the subsea sand monitors and pig detectors.For a consideration of US$1.8 billion, a Technip/Hyundai Heavy Industries consortium was awarded the engineering, construction, procurement and installation of the Akpo FPSO. Technip managed the overall project and engineering for the vessel, and HHI executed the FPSO\'s hull and topsides construction and integration. Nexan was subcontracted to provide the 736 miles (1,185 kilometres) of offshore cables for power and instrumentation on the FPSO.In an US$850 million contract, Saipem was awarded the engineering, procurement, construction, installation and commissioning of the umbilicals, flowlines and risers, as well as the oil loading terminal, the FPSO mooring system and the gas export pipeline from the Akpo FPSO to the Amenam AMP2 platform. Offshore installation is being carried out by the Saibos FDS and the Saipem 3000 vessels.
Production Akpo achieved first production in March 2009, and peak production of 175,000 barrels of condensate a day and 320 MMcf/d of gas is expected in the summer of 2009. Nearly 80% of this output is in the form of condensate, which is exported via a buoy located just 1.2 miles (2 kilometres) from the FPSO. The gas is piped 90 miles (150 kilometres) to the Amenam Kpono gas production platform; from there, it is sent via pipeline to the Bonny liquefaction plant.
