The first new-build semi-submersible drilling rig incorporating Wood Group Mustang Norway’s (WGMN’s) GG5000 floating hull design has been delivered to COSL Drilling Europe (CDE).
The COSLProspector was designed to operate in water depths up to 1,500 metres (5,000 feet) and drill wells up to 7,600 metres (25,000 feet). The unit is planned for use on the Norwegian Continental Shelf (NCS).
WGMN was responsible for the basic design and participated in the detailed design of the semi-submersible hull and main marine systems. The 50,000 man-hour project was engineered to Norwegian Petroleum Directorate (NPD) standards.
