C-Job Naval Architects delivers dredger design to GLDD

C-Job Naval Architects has delivered the basic design package of a trailing suction hopper dredger to Great Lakes Dredge and Dock Company. The ship is designed 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.

The vessel will be approximately 105.61 metres in length, 20.88 metres in breadth, 7 metres in depth and total installed horsepower of 16,500. The TSHD will have a hopper capacity of 6500 cubic yards. The vessel is scheduled to be fully operational by 2023.

‘At C-Job Naval Architects we believe the best designs come about in close collaboration with the client,’ says Harry Kikkert, Project Manager at C-Job. ‘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.

‘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,’ adds Lasse Petterson, Chief Executive Officer and President at GLDD.
