Island Offshore has taken delivery of a new subsea vessel from Ulstein, Island Performer, which is designed to operate in the Gulf of Mexico.
The SX121-design vessel has been built as part of a contract with FTO; a joint venture between FMC Technologies, Edison Chouest Offshore and Island Offshore.
The scope of the contract includes riser-less light well intervention and inspection, maintenance and repair tasks.
With the capability to operate at depths down to 3,000m, the Island Performer features a 250t active heave compensated offshore crane with a below-deck winch and two deep-sea work ROVs.
Island Offshore managing director Håvard Ulstein said: “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.”
Ulstein CEO Gunvor Ulstein said: “The three contracting companies combined have extensive competence in the advanced subsea segment.”
“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.”
Island Performer is claimed to comply with highest standards for station keeping, redundancy and dynamic positioning DNV-class notation DYNPOS AUTRO, which is equivalent to DP3.
The 130m vessel also has an Operation+ feature with a three-split configuration on main machinery, which helps maximise the operability in DYNPOS AUTR (DP2) operational mode, allowing it to retain system integrity and continue operations without interruption in case of a system failure.
Island Performer has a trial speed of 15.25k and can accommodate 130 people.
