This 90 m by 25 m floating production facility (FPF) is moored off Nigeria in 6 m of water, near the mouth of the Calabar River and will handle production from the Abana field, operated by Moni Pulo Ltd.
Expro Group, Aberdeen, holds a 5 year "supply and operate" contract for the FPF from Brass Exploration Ltd., a wholly owned subsidiary of Baker Exploration & Production.
According to Expro, the Agbani FPF, in Block OPL230, is designed to handle a production stream of 50,000 bo/d, and 42,000 bw/d, as well as provide the capabililty of injecting, at 1,000 psi, 52,500 bbl of seawater into the reservoir. Two 3.3 Mw gas turbines power the facility, which has accommodations for 40.
Oil is exported via a 45-km pipeline to the Knock Taggart floating, production, storage, offloading vessel (FPSO) moored in Block OPL98. Addax Petroleum Development (Nigeria Ltd.), a Swiss company, began production from Block OPL98 in February 1999 at a rate of 30,000 bo/d to the FPSO, which has a 60,000 bbl of fluid/day design capacity.
The Agbani FPF project commenced in March 1998 with the purchase of a newly built hull from China. Conversion began at Great Yarmouth, U.K., in August 1998, and the FPF was mobilized to Nigeria aboard a dry tow vessel, AMT Trasporer, in December 1998.
The mooring system for the shallow-water application was designed by Noble Denton Group, U.K., and built on the U.S. Gulf Coast. Expro describes the mooring as being an innovative system consisting of two fixed dolphin-type tripod structures with piles, driven to depths of up to 230 ft.
