A Singapore-based firm will construct a semi-submersible rig for UK-based drilling services contractor Diamond Offshore, as part of a rig enhancement programme, both firms said in press releases this month.
A wholly-owned subsidiary of Sembcorp Marine, Jurong Shipyard has inked a USD 135m deal with Diamond Offshore Drilling, Inc. for the construction of a moored semisubmersible rig named the Ocean Apex. Jurong Shipyard offers ship repair, shipbuilding, ship conversion, rig building and offshore engineering services.
The new drilling rig will operate in water depths of up to approximately 1,800 meters and will use an existing hull from another Diamond Offshore cold stacked unit, both firms said.
In addition, the rig will include a variable deck load of 7,000 long tonnes; a maximum hook-load capacity of around 907 tonnes; a 15K five-ram blowout preventer; and the capacity for 140 personnel. The Ocean Apex will have one of the largest deck areas of any semisubmersible drilling rig, Diamond Offshore said.
“We are pleased to have entered into this agreement with Juron Shipyard to enhance our deep water rig fleet with this high profile project,” said Executive Vice President of Diamond Offshore John Vecchio.
The deal follows Diamond Offshore’s ongoing fleet renewal program. The firm has ordered four new ultra-deepwater drillships and two deepwater semi-submersible rigs, which includes the Ocean Apex. Diamond’s fleet currently consists of 30 semisubs, seven jack-ups and one drillship.
