Rolls-Royce UT 771 CDL OSVs

Rolls-Royce has received an order worth £26m for the design, power and propulsion and equipment packages for four UT 771 CDL offshore supply vessels (OSVs).

The vessels will be the first UT-design OSVs with MTU engines, which will be built at Cosco (Zhoushan) Shipyard in China under an order from a Hong Kong-based ship owner.

Delivery of the four vessels is scheduled to take place in 2014; the order also includes an option for four additional vessels.

Rolls-Royce will also provide an integrated systems package including a propulsion system, a power electrical system, a bulk handling system, deck machinery, an automation and control system, and a dynamic positioning (DP) system.

The DP system uses satellite technology to automatically maintain a vessel’s position without anchoring.

Each UT 771 CDL OSV will be equipped with four MTU marine generator sets with 12V 4000 M23S Ironmen engines that will be delivered by Tognum.

Each generator set has a 1,380kW 12-cylinder high-speed diesel engine and will be mounted, with the alternators, on a common base frame.

Tognum said the generator sets are mainly designed for commercial marine applications like offshore supply vessels for wind parks or oil and gas platforms.

Another four UT-design vessels are currently being built by COSCO group at its Guangdong shipyard.
