LNG power for Island Offshore

Island Offshore has ordered a number of vessels from yards in the STX OSV group. More than 30 vessels have now been entrusted to the builder.

The latest delivery in a series of six vessels is, however, a significant milestone with a number of firsts being claimed. These include: the world’s first OSV to operate on pure LNG; the first LNG-powered UT vessel designed and powered by Rolls-Royce; and the first PSV in the world to operate in DP2 mode without using diesel.

The vessel with all these firsts, the UT776 CDG PSV Island Crusader, was delivered on 5 June this year by STX OSV. The hull was built by STX OSV Braila and towed to the Brevik facility for completion.

A total of six UT776 PSVs have been ordered by Island Offshore including the previously delivered Island Centurion and Island Captain. The next two in the series are to be LNG versions, Island Crusader being the first, and the second reportedly to be named Island Contender.

The vessel is diesel-electric. Rolls-Royce Bergen has supplied the four main generators: two diesel-driven C25:33L-6 models and two C26:33L-9 versions that run on LNG. The emergency generator diesel engine is a Scania D116. The extensive Rolls-Royce package of equipment for the ships also includes two AZP 120 CP main azimuthing thrusters, two tunnel thrusters forward, and a retractable azimuthing thruster, also forward.OSJ
