    Toisa Patroklos nearing completion

    Vessel & ROV News // May 12, 2015

    Hyundai Heavy Industries is approaching completion of Toisa Patroklos, a multipurpose offshore construction vessel, a customized Ulstein Deepwater Enabler design, for Sealion Shipping/Toisa.

    The vessel is the largest built with the patented X-BOW hullform and the first to be built in Korea. The vessel was launched in March 2015 and is scheduled for completion in the summer of this year.

    The DP3 vessel is 150.5m in length with a breadth of 32m and is designed for worldwide operations in the oil and gas sector, ultra deepwater installation and construction, flexible lay, pipelay, cable lay and topside construction support.

    The design has been developed for maximum efficiency and cost effectiveness featuring heavy lift capabilities with active heave compensation (AHC), two ROV moonpools, up to 50 tonnes/m2 deck strength and 250 POB accommodation.

    The AHC offshore crane is rated at 900t SWL, which is capable of working to a depth of 3,500m. A second AHC knuckleboom crane is also fitted, of 200 tonnes SWL which is capable of working at 2,000m.

    The vessel can accommodate a 550 tonne flex lay tower over the main moonpool and two 2,500 tonnes capacity carousels below deck.

    From the enclosed hangar two large work-class ROVs can be deployed over-the-side to port and starboard or through dedicated offset moonpools.

    The vessel will be delivered with all necessary interfaces to service ROVs and a saturation dive system.
