Sembcorp Marine, Jurong Shipyard gets US$ 568-million contract for semi-submersible deepwater rig for North Atlantic Drilling Ltd. The new rig will be constructed based on the Moss Maritime CS60 design – an enhancement of the Moss Maritime CS50E MKII harsh-environment ultra-deepwater semi-submersible rigs West Pegasus and West Leo which were delivered by Jurong Shipyard to Seadrill in March 2011 and January 2012 respectively. Delivery is scheduled no later than the first quarter of 2015. This new ultra-deepwater harsh-environment semi-submersible rig will be built for a water depth rating of 10,000 feet with a maximum drilling depth of 40,000 feet. It will be an N-Class compliant 6th generation rig capable of maintaining position dynamically in deepwater and with thruster assisted mooring in shallow water in the North Sea and the Barents Sea. The rig is also engineered and winterized to carry out year-round drilling operations in such areas. Don Lee, Jurong Shipyard’s Senior General Manager of Offshore Division, said: “With offshore drilling moving towards deeper waters and harsher environments, we are confident of leveraging on these emerging opportunities with our proven track record in the building of high-specification ultra-deepwater rigs."
