    Subsea 7 orders newbuild pipelay and construction vessel

    Vessel & ROV News // June 10, 2005
    The Board of Directors of Siem Offshore Inc has performed an assessment of the medium to long term market for rigid pipelay and subsea construction, and says it expects overall demand to grow and says development in the deeper waters will constitute a significant portion of such growth, particularly in West Africa and Brazil.

    Siem, through its subsidiary Subsea 7, has therefore signed a contract for a new-build rigid pipelay and construction vessel costing in the US$180-200 million range.

    The vessel, which is 157m long and has a 28.4m beam will have a top tension capability initially of 300 tonnes, upgradeable to around 400 tonnes, and will have a storage capacity of 3,500 tonnes of steel pipe on the main reel. The vessel will also have a400 tonne deepwater crane, a built-in deepwater ROV spread and a comprehensive survey system and will have the ability to install flexible flowlines and umbilicals. The completed ship is expected to be delivered in the second quarter of 2007.

    The vessel greatly enhances Subsea 7's pipelay capabilities, particularly in deepwater. She is a much larger vessel than Subsea 7's existing pipelay vessel, Skandi Navica, and will have almost 50 per cent more carrying capacity and double the top tensioncapability. The current charter on the Skandi Navica expires in December 2007, but can be extended through 2014 by seven one year extensions in Subsea 7īs option.
