COSL Drilling Europe (CDE) has taken delivery of its first new-build semi-submersible drilling rig, which features Wood Group Mustang Norway’s (WGMN’s) GG5000 floating hull design.
The COSLProspector, which is planned to be deployed in the Norwegian Continental Shelf (NCS), can work in water depths of around 1,500m and drill wells to a depth of 7,600m.

WGMN was responsible for the basic design and participated in the detailed design of the semi-submersible hull and main marine systems.
WGMN president Otto Søberg said: "The delivery of the rig, as designed, is the result of a highly successful collaboration among WGMN, CDE and Yantai CIMC Raffles Shipyard.
"We worked closely with CDE to ensure the design of the rig would meet its needs and objectives and with the shipyard to deliver the rig as planned, thereby avoiding costly construction modifications common to the industry."
WGMN had earlier undertaken the modification design and engineering for three other CDE drilling rigs that include COSLPioneer, COSLInnovator and COSLPromoter.
