Keppel FELS has developed the sixth generation semisubmersibles capable of working in the harsh environments of the North Sea deepwater region.
The high-specification DSSTM 51HE and DSSTM 60HE semis are among the world's most advanced drilling semis. Equipped with DP 3 capabilities, they have winterized features such as derrick cladding and machinery space heating.
Based on Keppel Deepwater Technology Group and GustoMSC's proven DSS series of designs, the rigs are capable of operating in water depths of up to 7,500 feet and drill up to 40,000 feet.
