Great Lakes Dredge & Dock has ordered the first two Multi Cat vessels to be built in the US for wide range of workboat tasks
Damen Shipyards Group approved a licence agreement with US-based Conrad Industries for these vessel designs, allowing Conrad Shipyard to begin construction of two Damen Multi Cats 3013 for Great Lakes Dredge & Dock this month.
Fully compliant with the US Coast Guard and US Army Corps of Engineers stability criteria, the vessels will be used for dredging support operations, logistics, anchor handling, towage and handling submerged and floating pipelines. Equipped with large winches and deck cranes, the tank capacities on board will be sufficient to supply dredgers with the required replenishments.
“This is a milestone moment for the US shipping industry and our company,” said Great Lakes Dredge & Dock chief executive Lasse Patterson. “The Multi Cats will give us the ability to dredge with enhanced operating efficiencies needed to maintain our shorelines and waterways.”
Damen said the Multi Cat design brings efficiency to a project, eliminating the need for floating support equipment such as derrick barges, towboats and anchor barges.
Operations will be safer, with hose and pipe maintenance work able to take place securely on deck, reducing the risk of man overboard compared with standard industry methods of using floating pontoons.
Damen sales manager Daan Dijxhoorn explained the process of building these vessels under licence. “These Damen Technical Cooperation (DTC) licensing agreements are a means by which US-based operators are able to access Damen’s vessel design portfolio in a manner fully compliant with the Jones Act,” he said.
“Licence holders construct the vessel themselves in the country, drawing upon Damen’s experience in the engineering and production of the platform and on Damen’s support throughout the building process,” said Mr Dijxhoorn.
DTC will tailor its support to Conrad’s requirements. Assistance could be from providing initial drawings to supplying parts in packages, or onsite consultancy.
Damen already provides designs to be built under licence in the US for a wide range of vessels types, including those operating in the harbour towage, terminal operations, offshore and dredging sectors.
