9 July 2014 – Norwegian shipbuilder Ulstein Verft delivered the state-of-the-art MV Island Performer to its owner Island Offshore today.
The flexible, Riserless Well Intervention Vessel/Inspection, Maintenance and Repair (RLWI/IMR) vessel will serve its first five years for FTO, a joint venture between FMC Technologies, Edison Chouest Offshore and Island Offshore in the U.S. Gulf of Mexico.
“The vessel is customized to suit the scope of work in the FTO contract, in which RLWI (Riser-less Light Well Intervention) and IMR (Inspection/Maintenance/Repair) are the main tasks. She is able to perform operations at depths down to 3,000 meters, and the contracted work start at year’s end,” says Managing Director Håvard Ulstein, Island Offshore. “However, the very first assignment will be for the RogFast connection in Norway, in which the scope of work will be to investigate the sea bottom.”
gCaptain got a sneak peak of the ship while we were visiting the Ulstein Verft yard last month, see Rob Almeida’s photos and report from the trip HERE.
‘Island Performer’ is a next generation subsea vessel designed and built by Ulstein, with large accommodation, storage and lifting capacities. She meets the highest standards for station keeping, redundancy and dynamic positioning (DNV GL class notation DYNPOS AUTRO, equivalent to DP3). Operability in DYNPOS AUTR (DP2) operational mode is maximized with help from the ‘Operation+’ feature, with a three-split configuration on main machinery allowing the vessel to retain system integrity and to continue operations even the case of a substantial single system failure.
A shelter deck stretching all the way past the main moon pool and aft to the main cranes increases the operational window for moon pool work and offers a shielded space for various equipment. On the shelter deck is a multi-skidding system for handling 100-tonne skidding pallets, a design also includes a heavy-load cargo deck for transporting equipment for various operations and construction work.
In addition to its design features, ‘Island Performer’ was also developed and built according to the latest international regulations for safety and comfort. The vessel is equipped with resiliently mounted tunnel thrusters, and carries the DNV GL class notation Comfort Class, COMF-V1, which ensures that noise and vibrations are kept at minimum. SCR (Selective Catalytic Reduction) catalysts are installed for all engines, as well as an ESD system (Emergency Shut Down system) in order to automatically close down systems in case of a hydrocarbon leakage. The vessel has a crew capacity of 130, and in case of evacuation, each of the lifeboats on the starboard and port sides can accommodate everyone on board.
As you can see the Island Provider also features patented ULSTEIN X-BOW® bow design.
“The three contracting companies combined have extensive competence in the advanced subsea segment,” says Gunvor Ulstein, CEO of Ulstein Group. Together, we have developed a solution which is particularly adapted to both RLWI and IMR work, and we strongly believe that the ‘Island Performer’ will prove her value in the years to come.”
