Statoil said Sunday it has canceled its contract for the COSL Innovator mobile rig, the same rig involved in a fatal accident in December.
“The conditions for terminating the contract signed with COSL Offshore Management AS have in our opinion been met, and we therefore choose to use our contractual right to terminate the contract,” Statoil’s senior vice president for drilling and well Geir Tungesvik said.
The COSL Innovator was working at the Troll field in the North Sea on December 30 when a breaking wave hit the rig, killing one worker and injuring two others.
The breaking wave also damaged the rig’s accommodation module.
Statoil added it has decided to stop drilling operations with the COSL Promoter when it is “safe to discontinue well operations.”
“This is done in order to enable COSL to implement the necessary actions in order to fulfill the requirements of the contract,” Statoil said.
China-based COSL has not commented on the matter yet.
Statoil said the contract termination may have “some short-term consequences” for planned drilling activities, but it does not expect any long-term production impacts at the Troll field.
Statoil added that its plans for gas and fluid production from the oil zone at Troll “remain firm.”
The Troll field lies in the northern part of the North Sea and contains about 40 percent of the total gas reserves on the Norwegian continental shelf.
