Island Performer

Ship history

Delivered on 8 July 2014. The vessel was customised to suit the scope of work in a five-year contract for FTO in the Gulf of Mexico, in which Riserless Light Well Intervention (RLWI) and Inspection/Maintenance/Repair (IMR) are the main tasks. A large intervention tower is placed over the 8 by 8-metre main moon pool. She is equipped with a 250-tonne AHC offshore crane with a below-deck winch, and carries two ROVs, one to be launched through a dedicated moon pool and the other from the starboard side.
However, the first assignment was to investigate the sea bottom for the RogFast mainland connection in Norway.

“Island Offshore has previous experience with this design. The two SX121 designed vessels already in our fleet have proved to be very successful to us."
Håvard Ulstein, managing director at Island Offshore

The vessel has large accommodation, storage and lifting capacities. She meets the highest standards for station keeping, redundancy and dynamic positioning (DYNPOS AUTRO, equivalent to DP3). Also, operability in DYNPOS AUTR (DP2) operational mode is maximised due to the ‘Operation+’ feature with a three-split configuration. This set-up allows the vessel to retain system integrity and to continue operations uninterruptedly even after a substantial single system failure.

A shelter deck with a multi-skidding system is stretching all the way past the main moon pool and aft to the main crane. This increases the operational window for moon pool work and offers a shielded space for various equipment. The design also includes a heavy-load cargo deck for transporting equipment for a multitude of operations and construction work.

‘Island Performer’ has been developed and built according to the latest international regulations in which safety and comfort are two key issues. The vessel is equipped with resiliently mounted tunnel thrusters, and she carries the DNV 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. An ESD system (Emergency Shut Down system) is installed in order to automatically close down systems in case of a hydrocarbon leakage. ‘Island Performer’ 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. Carrying the innovative X-BOW^®, the vessel has reduced speed loss in head seas, resulting in reduced fuel consumption and emissions to air.
