BP Greater Plutonio


Angola Block 18 

Landmark: Subsea development with largest Angolan content

Greater Plutonio is one of the largest contracts executed by FMC Technologies. The project is executing some significant "firsts" in Angola. In addition to the production of six manifolds and 42 PGBs at local suppliers, 25 of the subsea trees are assembled locally at the FKIA Luanda Base. A comprehensive training program of Angolan nationals is completed. Management, fabrication, assembly and offshore service assistance are localized in Luanda. A 4,600 ft2 (1,400 m2) Pipe Work Fabrication Hall in Lobito is built for execution of the manifold contract. The Greater Plutonio project will initially develop five fields: Galio, Cromio, Paladio, Plutonio and Cobalto. A spread-moored FPSO, located southeast of Paladio, will process the fluids produced from the subsea production wells. A single flowline will accommodate production from the Northern system (Galio, Cromio and Paladio), and a looped flowline system will accommodate production from the Southern system (Cobalto and Plutonio). Manifolds will be offline from the flowlines and connected via tie-in spools to inline tree assemblies. Water injection will be used to provide reservoir pressure maintenance. Injection water will be transported by a single flowline for the Northern system, and by two flowlines for the Southern system. First oil was achieved on October 1st, 2007.
