    Siem Spearfish mobilized in Gulf of Mexico with well intervention spread

    Vessel & ROV News // July 1, 2014

    Harkand recently completed project management and engineering for the mobilization of Siem Spearfish in Port Fourchon, Louisiana after arriving just nine days earlier from Vard shipyard in Norway.

    The newbuild multipurpose service vessel (MPSV) was designed and built with input from Harkand, particularly around the deck layout, to increase the efficiency for mobilization and demobilization.

    The mobilization included installation of a high specification survey spread, two work-class ROVs, and a riserless well intervention spread.

    Siem Spearfish is now on hire and will be initially completing riserless well intervention works in water depths ranging from 6,700ft-8,100-ft in the Gulf of Mexico.

    The 120.8m vessel is equipped with a 250 tonne AHC offshore crane with 3,000m of wire and two Triton 4,000m XLS ROVs including active heave compensated umbilical winches built into the vessel. Siem Spearfish can accommodate 110 people. The main deck area is 1,350m2 with a strength of 10Te/m2, a 7.2 x 7.2m work moon pool and has removable aft bulwarks.
