Ship history

Delivered from Ulstein Verft on 11 July 2008, three days ahead of the contractual deadline. Named at the Ålesund Boat Festival on 12 July 2008.

The vessel was chartered by Oceaneering® and contracted to work for Shell on the Perdido development project in the US section of the Gulf of Mexico. The ship was to perform installation work in ultra-deep waters.

At the time, the Olympic Intervention IV was the largest Multi Service Vessel in the Oceaneering® deepwater fleet. Examples of subsea hardware installations included umbilicals, subsea trees, jumpers, flying leads, and manifolds. IMR projects ranged from pipeline inspections and repairs to choke changeouts. Well intervention services included well stimulation and plug and abandonment operations. The vessel features a satellite communications equipment system capable of transmitting streaming video for real-time work observation by shore personnel.

"The ship is built for Arctic waters, which makes her better suited for rough conditions," said T. Jay Collins, President and CEO of Oceaneering®.

Ulstein Verft had a deadline on this vessel that was seven weeks shorter than on her sister ship, the 'Olympic Triton', in addition to large delays on essential equipment. Nevertheless, the yard still managed to uphold a standard of quality and deliver with time to spare.
 

The ULSTEIN P101 has excellent seagoing properties with smooth motions, and provides a steady platform for most operations. 
 

End May 2019: Olympic Intervention IV was awarded a two-month contract with further options within the renewable market.
