specialist offshore vessel, Derrick Barge 50 (DB50). Te heavy-liſt 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. Tis latest contract demonstrates customer confidence in our technology and service.” John Nesser, J. Ray McDermott executive vice-president
and chief operating officer, said: “Tese 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.” Te six thrusters are each capable of providing 44tonnes
of thrust and have a variable-frequency electric motor drive and a fixed-pitch propeller. Tey 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. Te new diesel-engine generator sets provide 19.2MW and, with the new thrusters, provide increased propulsion
and electrical power to DB50. DB50 is capable of liſting loads of up to 4400tonnes
and laying pipe up to 20inches in diameter in more than 9000ſt of water. In March 2009, Rolls-Royce opened a new facility in Galveston, Texas. Encompassing 40,000ſt2
, 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.
