Bardex Corp. says it has received a new mooring system order for Chevron’s semisubmersible production unit in the Gulf of Mexico.
GOLETA, California – Bardex Corp. says it has received a new mooring system order for Chevron’s semisubmersible production unit, to be moored in approximately 7,000 ft (2,133 m) of water in the Walker Ridge area of the Gulf of Mexico. The system will be used to develop the adjacent Jack and St. Malo oil reservoirs.
Bardex will supply sixteen (16) Chain Jacks designed to pull-in the 165 mm (6.5 in.) R4S studless mooring chain up to a stall load of 8,000 kN and integral chain stoppers to support the full MBL of the chain of 25,500 kN. The Chain Jacks will be fully instrumented and can be operated either manually by pendent control or by a fully automated PLC-controlled system.
Sixteen turndown sheaves will handle the slack chain exiting each Chain Jack and redirect it to the chain lockers. The Chain Jacks will be powered by a Bardex designed Hydraulic Power Unit (HPU) comprising four (4) 350 hp electric motor/pump assembles and 1,000 gallon reservoir with an air-cooled heat exchanger.
