Offshore Vessel Upgrade For Rolls-Royce

Posted on February 5, 2010

Rolls-Royce has received an order worth over US$20 million to supply diesel generator sets and thrusters to Houston-based offshore engineering and construction company J. Ray McDermott.

The order, which includes six underwater mountable azimuth thrusters and four Bergen generator sets, is being supplied as part of a major upgrade to the customer’s specialist offshore vessel, Derrick Barge 50 (DB50). The heavy-lift derrick and pipe laying vessel is based in the Gulf of Mexico and is capable of lifting loads of up to 4400 tonnes and laying pipe up to 50.8 cm in diameter in more than 2743.2 m of water.

The six thrusters are each capable of providing 44 tonnes of thrust and have a variable frequency electric motor drive and a fixed pitch propeller. They will interface with the vessel’s dynamic positioning system to significantly increase the station-keeping capability of the vessel, allowing it to operate in more severe weather conditions. The new diesel-engine generator sets provide 19.2 MW and, with the new thrusters, provide increased propulsion and electrical power to DB50.

In March 2009, Rolls-Royce opened a new facility in Galveston, Texas, U.S.A. The new Rolls-Royce Marine service center in Galveston provides repair and overhaul services in support of the company’s entire portfolio of marine products to customers throughout the Gulf of Mexico region. In the past year Rolls-Royce has strengthened its global marine services network, opening six new service center facilities, in North America, South America, Europe and the Middle East.
