    Heerema provides update on new crane ship

    Vessel & ROV News // May 8, 2007

    Heerema Marine Contractors (HMC), which is investing US$1 billion in a new deepwater construction vessel, has provided more information about the vessel and says it will feature "unrivalled speeds and state-of-the-art equipment."

    "It will enable HMC to operate in remote areas and ultra deepwater increasing the pace of field development worldwide," said the company in a statement at OTC 2007. "Once the vessel enters the market in 2010, it will secure construction capacity for at least another three decades."
    The conceptual design was prepared in-house by Heerema Marine Contractors and is based on a vessel that is 220m long, with a breadth of 88m.

    The newbuild will have a maximum speed of 20 knots - up to four times the speed of our current deepwater construction vessels.

    "The high speed capacity of the new vessel will dramatically cut travel time between projects and provide our clients with more productivity in a broader range of geographic areas," said HMC.

    There will be facilities for 550 people, upgradable to 750 people. The ship's payload is 25,000 tonnes and the power generation capacity will be of 75MW. The Dynamic Positioning Station keeping system will be of NMD Class III.
    The dual crane capacity of 15,000 tonnes will enable the vessel to install the largest and heaviest fixed and floating structures. "The new J-Lay tower and deepwater lowering construction means we can install pipelines and structures from 200-3,500m water depth with a maximum of 32in OD," said HMC. "The tension capacity will be 2,000 tonnes - this is double the capacity of the Balder." 
    Because of its design and speed, the new vessel will make offshore construction in the Arctic feasible. The placement of the cranes, the J-Lay tower and other installation equipment, as well as the structural quality of the hull and thrusters, are well suited for the Arctic.
    This summer long-lead components, such as the cranes and J-Lay tower, will be ordered.

    Options are currently being discussed with possible suppliers.
