    Sea of Solutions provides design for Global 1200 pipelay/heavy lift vessel

    Vessel & ROV News // August 31, 2007

    Sea of Solutions designed the new pipelay/heavy lift vessel Global 1200.

    US offshore major Global Industries has awarded Keppel Singmarine the construction contract for its new pipelay / heavy lift vessel Global 1200.

    This is the third new build vessel contracted in 2007 to be designed by Dutch design company Sea of Solutions (SoS), a partner in the Offshore Ship Designers Group.

    The previous two major vessels designed by SoS contracted this year were a 5,000 tonne heavy-lift vessel for Nordic Heavy Lift and a pipelay/heavy lift vessel for Larsen & Toubro.

    Sea of Solutions was responsible for both concept and basic design of all three vessels.

    Scheduled to enter service in April 2010, the dynamically-positioned Global 1200 is a combination derrick/pipelay vessel with 1,200 tonne lifting capacity, 60in pipe laying capacity, and 400 tonne deep water lowering system capacity.

    The Global 1200 is a customised version of the Sea of Solutions’ SOC 600 design and will be able to pass through the Panama and Suez canals.

    The design incorporates an AmClyde single post crane on the aft and a centre firing line on the freeboard deck, the latter being a distinctive feature of most Sea of Solutions pipelay designs. For this project Sea of Solutions teamed with Vuyk Engineering, one of its engineering partners.

    The vessel is propelled by two 4,500kW thrusters providing a trial speed of 15 knots. Combined with the five retractable thrusters of 2,400kW each and an 880kW tunnel thruster the vessel is classed DP 2, however diesel-generator and switchboard lay-out meet DP3 requirements to provide additional reduncancy.

    The newbuild will be 162.3m overall, with legnth (bp) of 153.4m, breadth (moulded) of 32.2m, depth (moulded) of 16.1m, and draft (operational) of 5.8m. The vessel's speed will be 15 knots, and total installed power will be 3 x 4,230kW and 3 x 3,760kW.
