Designed for maximum uptime with reduced emissions and discharges, the DSS™ Series of semisubmersibles is among the world's most technically advanced deepwater drilling rigs. These rigs can operate at a water depth of 3,000 metres (10,000 feet) and are suited to drill deep and complicated wells of 10,000 metres (30,000 feet).
Rigs in the Series also have distinct ‘double-skin' columns, which protect the critical equipment within from damage by external impact. This greatly reduces rig downtime in the case of hurricanes or strong climatic pressures out at sea. The layout of the engine rooms has also been designed to minimise the potential of both being shut down at the same time in an emergency.
With their robust features, DSS™ rigs are well-suited to operate in the deepwater golden triangle comprising offshore Brazil, West Africa and Gulf of Mexico, and may be further customised to meet the unique challenges of each location.
These well-established DSS™ Series of semisubmersibles are jointly designed by Deepwater Technology Group (DTG) and GustoMSC.
Advancing Keppel's innovative suite of deepwater solutions, the DSSTM 38E is an enhancement of the DSSTM 38. It is rated to drill to depths of 10,000 metres below the rotary table in 3,000 metres water depth.
The DSSTM 38E has accommodation facilities to house a crew of up to 160 men. It has both vertical and horizontal riser storage. The vessel is also designed to keep position via eight azimuthing thrusters and the configuration complies with the American Bureau of Shipping's Dynamic Position System (DPS-3) requirements.
Designed to maximize uptime with reduced emissions and discharges, the DSSTM 38 rig is well-suited to handle the operational requirements in the deepwater "Golden Triangle" region, which comprises Brazil, Africa and the Gulf of Mexico.
