Rolls-Royce has won a £15m order to provide the design, integrated power and propulsion systems, and deck equipment for a pair of offshore service vessels to be built for Island Offshore.
The order also includes an option for an additional four vessels.
STX OSV will build the two vessels, which are scheduled for delivery in the latter half of 2013, at its Brevik shipyard in Norway.
Each of the vessels that has been ordered will have a length of 84.3m, beam of 17m and capacity of 3,800dwt.
Rolls-Royce general sales manager of offshore Per Kristian Furo said, "We have worked very closely with Island Offshore over the last decade to develop a wide range of advanced and highly efficient platform supply and subsea service vessels."
"This long-standing relationship has resulted in 40 vessels being delivered or under construction," Furo said.
The UT 717 CD platform supply vessels (PSVs) will feature an integrated power and propulsion system incorporating main engines, controllable pitch propellers, bow and stern thrusters, deck machinery and an automation and control system.
In addition to this latest order, Island Offshore has a further three UT vessels under construction to be delivered from the Norwegian yard, which includes two LNG-powered offshore vessels.
In August this year, Rolls-Royce received a £20m order to design and supply power and propulsion systems for two UT 776 CD supply vessels for Island Offshore.
The UT 776 CD vessels are designed to transport essential supplies to and from offshore oil and gas platforms.
The vessels will also feature a dynamic positioning system, which uses satellite technology to maintain the vessel’s position, a comprehensive range of deck machinery and a bulk handling system for the safe loading of cargo.
The order also included a fully integrated and efficient diesel-electric power and propulsion system featuring four Rolls-Royce Bergen engines powering two Azipull thrusters.
