Netherlands-based naval architect C-Job has delivered the basic design package of a new trailing suction hopper dredger (TSHD) to Great Lakes Dredge and Dock Company.

GLDD required C-Job to develop a TSHD for beach nourishing and channel maintenance activities. C-Job created an initial and concept design which evolved into the current basic design package from which the ship will be built by Conrad Shipyard.

The vessel will be about 346ft in length, 69ft breadth, 23ft depth and total installed power of 16,500 bhp. It will have a hopper capacity of 6,500 cu yd.

Harry Kikkert, Project Manager C-Job, said: “At C-Job Naval Architects we believe the best designs come about in close collaboration with the client. From the start of this project, key members of the technical fleet managers were involved in the design process. 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 boasts two suction pipes and has been specifically designed to be easy to build. The hull shape was kept relatively simple while incorporating hydrodynamic design optimisations. This will make the vessel easy to build while still being fuel efficient. In addition, the design is ballast free which will reduce investment and operational costs."

Lasse Petterson, CEO and President, GLDD said: “As the leader in the US Dredging industry, Great Lakes continues to strategically invest in its dredging fleet. This highly automated new build vessel will increase the capabilities of our hopper fleet in the coastal protection and maintenance markets as well addressing specific needs in the growing offshore wind market. We are proud to utilise American engineered and built engines, dredge pumps, technology and dredging installations to create a highly efficient and productive vessel to meet our nations’ maritime infrastructure needs. The construction of this Jones Act qualified vessel, at peak construction, will create 150 high paying shipyard jobs and upon delivery the ship will be crewed by US citizen mariners. This vessel reinforces our commitment to the US Army Corps of Engineers and faith in the future of the US dredging market.”

The vessel is scheduled to be fully operational by 2023.
