Rolls-Royce, the global power systems company, 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.
Jarle Hessen, Rolls-Royce Sales Manager E&P Propulsion said: “We have extensive experience in offshore vessel design and equipment systems and our thrusters and engines are well-proven in the offshore market. With our new marine service centre in Galveston, Texas, we have also strengthened our customer support capabilities in the Gulf of Mexico area. This latest contract demonstrates customer confidence in our technology and service.”
John Nesser, J. Ray McDermott Executive Vice President and Chief Operating Officer, said: “These improvements, along with other modifications to the ship’s systems over the three year upgrade programme, will add tremendous value to the vessel’s capabilities, which will ultimately prove beneficial to our customers’ deepwater projects.”
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 megawatts and, with the new thrusters, provide increased propulsion and electrical power to DB50.
DB50 is capable of lifting loads of up to 4,400 tonnes and laying pipe up to 20 inches in diameter in more than 9,000 feet of water.
In March 2009, Rolls-Royce opened a new facility in Galveston, Texas. Encompassing 40,000 square feet, the new Rolls-Royce Marine service centre at Galveston provides state-of-the-art repair and overhaul expertise 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 centre facilities, in North America, South America, Europe and the Middle East.
