NORWICH, UK – Aquaterra Energy has won a contract to design, fabricate, and install a minimum facilities conductor supported platform (CSP) offshore West Africa for South Atlantic Petroleum Benin S. A. (SAPETRO).
Earlier Aquaterra Energy performed a detailed pre-engineering design study which led to development of a rig-installable solution. Installation of the Sea Swift CSP started at the end of March in 26 m (85 ft) of water.
The platform, currently under construction inAfrica, will be installed by a jackup rig. It will feature a two-deck topsides, a boat landing, and a subsea jacket structure. The platform will connect three planned wells to an onshore processing facility 15 km (9.3 mi) away.
Four 30-in. well conductors tied together by the subsea jacket structure will provide structural support to the topsides while also housing the well casings. Wellheads and christmas trees will be accommodated on the production deck. All equipment will be controlled from the onshore facility via a fiber-optic communication/power cable.
Riser guides, providing support and protection to the export riser and power cable will be located on two of the well conductors.
