Rolls-Royce has secured a £24m order from China’s Cosco Guangdong Shipyard to design and equip four offshore service vessels (OSV).

The vessels will be built on the UT 771 CDL design and will feature a fully integrated equipment system including diesel electric propulsion, deck machinery, bulk handling equipment and automation and control systems.

Rolls-Royce senior vice president of ship technology – offshore Jørn Heltne said, "These vessels are complex, highly efficient and designed to meet specific challenges faced by the offshore industry."

Scheduled to be delivered in early 2014, the four vessels will be equipped to transport pipes, equipment and cargo to and from pipe-laying barges, oil drilling and production platforms.

The company has not disclosed the ship owner who has ordered the vessels which also includes options to build an additional six vessels of the same design.

Cosco, earlier this week had won a $105m contract from an undisclosed American ship owner to build four new platform supply vessels (PSVs) and a $150m contract with a European ship owner to build offshore wind turbine installation vessel.

Cosco subsidiary Cosco Guangdong Shipyard will build the UT 771 CDL PSVs, which is scheduled to be delivered in early 2014.
