Jurong polishes first Larsen semisub

Singapore’s Jurong Shipyard has wrapped up major construction work on Petrorig 1, the first of four ultra-deepwater semi-submersible drilling rigs the yard is building for Larsen Oil & Gas.

Jurong parent SembCorp Marine said turnkey work on the rig was wrapped on schedule and the rig was on track for delivery in March. Its maiden assignment is under a five-year charter with Petrobras in the Gulf of Mexico. The rig was named in a ceremony at the yard and will now move to an anchorage to allow thrusters to be installed. The Petrorig 1 is a sixth-generation rig built to the Friede & Goldman’s Ex-D Millennium design. The dynamically positioned rig will be capable of drilling in to depths of up to 37,500 feet in water up to 10,000 feet deep. The rig has an operational displacement of 46,750 tonnes and a deck-load capacity of up to 8000 tonnes. Petrorig 2 has landed a five-year charter with Petrobras off Brazil and Petrorig 3 has been handed a three-year gig with Pemex off Mexico.
