JUNE 21, 2012 — Island Offshore, in which the Chouest and Ulstein families are partners, took delivery of the platform supply vessel MV Island Crusader from STX OSV's Brevik, Norway, shipyard.
The platform supply vessel has been built to Rolls-Royce UT 776 CDG design, with G signifying gas operations. Island Offshore says it is "the first offshore supply vessel in the world to operate in DP II without using diesel." It is also the first gas powered Rolls-Royce design offshore service vessel.
Managing Director of Island Offshore, Håvard Ulstein, said: "A very important area for Island Offshore is reduction in fuel consumption. With the UT 776 CD, the favorable hull lines contribute to a very low consumption rate over a wide range of operating drafts. We believe that the most significant contribution to reducing emissions is to reduce fuel consumption for a given amount of work done. Going for LNG fuel is a logical step in reducing emissions even further."
Jørn Heltne, Rolls-Royce, Senior Vice President, Ship Technology – Offshore said: "As always it is a pleasure to see a new vessel delivered to satisfied owners. This innovative vessel is the first of its kind and is designed to reduce the impact on the environment while increasing fuel efficiency. We are very pleased that Island Offshore has again placed its trust in our technology and offshore design expertise."
This is the first offshore vessel to feature lean burn gas engines as main engines. As a result Nitrogen Oxide (NOx) emissions will be reduced by about 90 percent while Sulfur Oxide (SOx) emissions and particulates will be negligible. CO2 emissions will also be significantly reduced.
The vessel is also equipped with two diesel engines for periods when it needs to operate away from gas supply.
Island Crusader will operate in the North Sea undertaking transport, supply and service duties between onshore supply bases and offshore drilling sites. It is 96 m long and will also be equipped for oil recovery.
Including this latest delivery, Island Offshore has seven UT 776 CD platform supply vessels in service and three more under construction.
