    Catamaran workboat for Australia’s North West coast

    Vessel & ROV News // May 22, 2008

    Offshore Unlimited's new workboat will be built at Richardson Devine Marine.

    Incat Crowther has announced they have been selected to design a 24m catamaran workboat for Offshore Unlimited which is to be built at the new Richardson Devine Marine facility in Hobart, Tasmania.

    The design will be based on Incat Crowther’s recent successes in catamaran workboat design, utilising their high carrying capacity hullforms and capitalising on their experience to develop durable aluminium structures.

    The new vessel will be a 24.0m high speed catamaran workboat capable of carrying 50 tonnes of deadweight with a service speed of 26 knots. The main deck, which will have a carrying capacity of 24 tonnes, will be arranged for multiple uses and will include a moonpool for exploration services and the ability to carry a 20ft container. The deck will be serviced by a Heila deck crane capable of lifting 3.5 tonnes.

    The main accommodation block is located fwd and contains space for a crew of 10. The main deck cabin houses the galley and crew mess area, along with two crew cabins for the senior crew. Wash facilities are also located on this deck, one accommodating laundry facilities. Junior crew cabins are located in both the port and starboard hull with a large pantry located aft in the port hull.

    The wheelhouse is located on the upper deck and features all round visibility from the helm seat. Crew and passenger seating is provided around the perimeter of the cabin. Two wing control stations are fitted forward on either side with a tender/rescue boat located aft within easy reach of the deck crane.

    Powered by twin Caterpillar C32’s each producing 1,300hp the vessel will have a service speed of 26 knots at half load. The vessel will have an extended range of 1,875nm at 22 knots due to two large 12,500 litre fuel tanks.

    The vessel will be built by the Tasmanian shipyard, Richardson Devine Marine (RDM) and is expected to be completed by the end of this year.

    This will be the first catamaran work boat built by RDM.
