The contract covers the pigging of production, water and gas injection flowlines; hydrostatic testing of the flowlines, riser and jumpers; followed by dewatering of the gas injection system. During installation and post installation Weatherford will also perform electrical and pressure monitoring and testing of the umbilicals from the floating production, storage, and offloading vessel (FPSO).
Weatherford will utilise the Weatherford patented Denizen subsea pipeline commissioning system on this project, which will be the first deployment of such technology in Ghana. The company will also mobilise a high pressure membrane generated nitrogen spread, which will be based on a support vessel and used to dewater the gas injection riser and flowlines.
The Jubilee Field Development comprises production wells, water injection wells, and gas injection wells, to be tied-in via manifolds and riser bases to an FPSO located 130 km west southwest of Takoradi in water depths from 900 m to 1,700 m.
