Petrorig I—the first unit of a series of four Larsen Oil & Gas ultradeepwater semisubmersible drilling rigs on order with Sembcorp Marine Ltd. subsidiary Jurong Shipyard—has completed its turnkey construction on schedule and is on track for assignment in the Gulf of Mexico. The rig is scheduled for delivery and sail-away in March for a 5-year charter with Petrobras America in the gulf.
Petrorig I was built using Jurong Shipyard’s proprietary breakthrough techniques for fast-track semisubmersible construction and is a sixth-generation Friede & Goldman’s Ex-D millennium class design semi capable of drilling up to 37,500 ft while operating in dynamic positioning mode in ultradeep waters of up to 10,000 ft.
The rig is equipped with an operational displacement of 43,400 tonnes at 17 m draft and 46,750 tonnes at 20 m draft, 18,000 sq ft of usable deck space, and is capable of a variable deck load capacity of up to 8,000 tonnes. Photo from Sembcorp.
