    Ulstein Sea of Solutions develops new derrick pipelay vessel for NPCC

    Vessel & ROV News // April 15, 2009

    Abu Dhabi-based National Petroleum Construction Company Ltd (NPCC) has awarded Dutch design office Ulstein Sea of Solutions a basic design contract for a new large derrick pipelay vessel DLS-4200.

    The new vessel will be one of the biggest vessels of its kind, combining S-lay double joints pipelay operations with 4,200 tonnes lifting capacity.

    The design of the vessel is a modified version of the SOC 3000 design from Ulstein Sea of Solutions and will be equipped with an Amclyde Model 80 crane.

    The DLS-4200 is designed to operate worldwide, but will initially be equipped with a mooring system to operate in the Arabian Gulf and India. However, a future DP2 upgrade is envisaged and catered for in the design to minimise the technical impact in the future.
