  • High Capacity Derrick Barge Required

    Manson Construction Company of Seattle initialized a project to build a new, high capacity derrick barge for marine construction service. Glosten designed the barge hull to suit Manson’s innovative operational needs.

    Conflict Resolution

    The barge needed to support a huge crane and extensive construction hardware, but also maintain the maximum clear deck area for construction services work. Shipyard constructability and schedule issues were also a concern.

    Creative Engineering Solutions

    Maximum clear deck area was achieved by installing the large mooring winches below deck, with mooring wires running through line galleries under the deck to overboarding sheaves mounted in recessed pockets at each corner of the hull. With the goal to design the hull that Manson needed, while considering shipyard constructability and schedule issues, Glosten engineering efforts were carried out in consultation with Gunderson Marine, of Portland, Oregon, the barge hull builder. Glosten designed the barge hull in detail and obtained ABS Class approval including stability approvals to allow unlimited, offshore derrick barge service.

    h4>Delivery Complete

    The barge hull was delivered to the Manson yard in Houma, Louisiana, where Manson completed the outfitting and commissioning. Glosten supported Manson on-site with technical guidance on mechanical systems and resolving regulatory questions. The derrick barge has an American MG509 crane with a 265′ boom, and a capacity of 1000 tons over the stern and 800 tons fully revolving.
