Angola Block 17

Landmark: 2003 Offshore Technology Conference "Distinguished Award" winner

The Girassol development is located off the coast of Angola, West Africa, Block 17 at a water depth of 4,430 ft (1,350 m). Hydrocarbons are produced via the subsea production system to an FPSO. The subsea production system comprises wellheads, trees, manifolds, flowline connection systems and control and well intervention equipment, based upon FMC Technologies' modular guidelineless and remotely operated technologies. Girassol represents one of the most ambitious field developments with a high degree of technological innovation in a new geologic area with aggressive cost and schedule targets. The project represents the first step to the industrial prototype of a series of major developments on the Block 17 offshore Angola. Additional equipment was added in 2007: two production subsea trees (delivery 2008 and 2009) and one production flowbase (delivery 2009).

  • Forty-seven vertical 5"x2" 5,000 psi subsea trees
