Rolls-Royce has announced that Island Offshore will further expand its fleet of Rolls-Royce UT776 platform supply vessels (PSV) using LNG for fuel.
These vessels will be the first LNG-powered UT vessels designed and powered by Rolls-Royce. The latest order by Island Offshore is for two PSVs.
At present they have four of the UT 776 supply vessels in service and two more under construction.
The vessels will be built by STX Offshore Norway at its Brevik yard, which has previously built a number of vessels for the ship-owner.
Rolls-Royce has worked for several years developing designs and systems for offshore vessels using LNG as fuel.
Rolls-Royce has developed a gas-electric diesel-electric propulsion system for the new vessel. The effective capacity of the gas tanks is about 200 cubic-metres, corresponding to 10-20 day operation on gas alone depending on the exact operational profile. The gas engines are two of the new C26:33 series from Rolls-Royce.
The new UT776 CDG is 96 metres long with a beam of 20 metres, and will transport all normal offshore supplies. The ship will also be equipped for oil recovery.
