C-Job Naval Architects has delivered the basic design package of the trailing suction hopper dredger to Great Lakes Dredge and Dock Company.
GLDD called on C-Job, the global independent ship design and engineering company, to develop their TSHD for beach nourishing and channel maintenance activities. Working closely together with the American dredge industry leader, C-Job created the initial and concept design which evolved into the current basic design package of this fit for purpose dredger. This package is the information from which the ship will be built by Conrad Shipyard, as announced by GLDD on 9 June.
The vessel will be approximately 346 feet in length, 69 feet in breadth, 23 feet in depth and total installed horsepower of 16,500. The TSHD will have a hopper capacity of 6,500 cubic yards.
Harry Kikkert, Project Manager at C-Job, says: “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 optimizations. 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, Chief Executive Officer and President at GLDD says “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 utilize 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.
