    Master Marine in Norway, an offshore service company, specialising in the transportation and offshore installation of heavy structures for the oil and gas industry, which has two self-propelled 'Service Jack' self-propelled jack up vessels under construction at Drydocks World in Indonesia, has been awarded its first contract.

    The first Service Jack will be delivered in the first quarter of 2010 and the second vessel in the third quarter of 2010, and Master Marine has just announced that the first vessel - known as  Service Jack 1 - has recently been awarded a contract with ConocoPhillips Scandinavia for the Ekofisk Renewal Project.

    The vessel has been contracted as a jack up accommodation unit. By utilising the free deck area, the accommodation capacity has been increased from 260 beds to 447.

    In addition the vessel will be outfitted with recreation areas, offices and workshops.

    The two large revolving cranes in the Service Jack concept will be replaced by a smaller crane, making the vessel more suitable as an accommodation unit. These modifications will add a total of 65 million Euro to the investment costs, so that the total all inclusive cost for this vessel will be Euros 265 million.

    The contract award is for a fixed thre year charter, with the option for additional 2 x 12 months. The gross contract value for the fixed period is in excess of Euros 260 million and mobilisation will be in July 2010.

    The new accommodation unit will replace some of the existing accommodation vessels/platforms on the Ekofisk Complex.

    Said Master marine: "The Service Jack’s unique design offers increased stability and meets the 10,000 year North Sea wave criteria. In addition, the new unit will serve as a support vessel for the upcoming 'Greater Ekofisk Area' offshore campaigns."

    "In the contract it is stipulated that the unit can be utilised at the Ekofisk Complex, Greater Ekofisk Area and/or the North Sea Business Unit area, meaning any of the ConocoPhillips facilities in the Norwegian and UK sectors of the North Sea."

    "This contract illustrates the true versatility that the Service Jack represents and the flexibility it offers," the company said.

    The second vessel, Service Jack 2, is expected to be constructed as a construction vessel with the capacity of performing topside and jacket installations by tandem lift (up to 1,500 tonnes revolving crane capacity) or single lift topside installations by  skidding (up to 7,200 tonnes capacity).

    In order to reduce offshore hook-up time, the Service Jack can handle fully integrated and commissioned topsides from onshore fabrication site, including load out using its own gear, transportation to field using its own propulsion, positioning at field using its own propulsion/DP system, elevating the laden hull by using the Service Jack's jacking system, offshore load transfer of whole topside in one single operation by skidding and working as tender barge during the hook up phase.

    This reduces or eliminates the need for additional support/service vessels during the installation and hook-up and commissioning phase.

    In addition to the offshore oil and gas industry, Master Marine sees great potential in the renewable energy sector, in particular related to wind farm installations where the unit with it’s stability and extreme crane range will be very well suited, and notes that the Service Jack is also well-suited for subsea installation work and for platform decommissioning.

    Unit number two has been tendered for several opportunities, and the company is currently in contractual negotiations also for this unit.
