C-Job Naval Architects has delivered the basic design package of the trailing suction hopper dredger to Great Lakes Dredge and Dock Company (GLDD).

C-Job created the initial and concept design which evolved into the current basic design package of the dredger, which will be used for beach nourishing and channel maintenance activities.

“From the start of this project, key members of the technical fleet managers were involved in the design process,” said Harry Kikkert, project manager at C-Job. “Their feedback and those of the crew of which they were in close contact with were paramount to shape the design as it stands now.”

The TSHD will have two suction pipes and has been specifically designed for a straightforward build. The hull shape has been kept relatively simple whilst incorporating hydrodynamic design, making the vessel easy to build while still being fuel efficient. In addition, the design is ballast free which will reduce investment and operational costs.

Built by Conrad Shipyard and scheduled to be fully operational by 2023, the vessel will be approximately 346 feet in length, 69 feet in breadth, 23 feet in depth and with a total installed horsepower of 16,500. The TSHD will have a hopper capacity of 6,500 cubic yards.
