A new series of dredgers has self-propulsion as part of the new design.

Netherlands-based C-Job Naval Architects has launched a new series of Cutter Suction Dredgers (CSD), with a self-propelled concept design.

The 34-inch self-propelled cutter suction dredger features cutter power of 3500 HP and a total installed power of approx. 26000 HP. The CSD includes two 6300 HP dredge pumps on deck and one 3500 HP submerged dredge pump on the cutter ladder, enabling a maximum dredging depth of 95 feet (29m). The self-propelled CSD boasts a length of 296 feet 90m), which can be extended to provide an increased swing width.

The CSD series presents the solution for mid-range cutter suction dredgers featuring a dredge discharge diameter of 20 to 40 inches and total installed power from any size up to 30000 horsepower.

Thanks to the adaptive platform underpinning the CSD series, shipowners can completely tailor the design to their desired operational profile while benefiting from a full range of design solutions. Options include self-propelled or stationary service, anchor boom system, barge loading system, motion compensation in the spud carrier system, Christmas tree system, and spud tilting system.

Fuel options are standard systems or renewable marine fuel, such as methanol or a combination via dual-fuel propulsion.

“The new CSD series is a bold design that brings industry leading performance in a dynamic modular package. With advanced features like motion compensation and a wide range of options it demonstrates the start of what is possible with the C-Job CSD series,” says VP of Business Development Todd Allen. ”Our new CSD series builds on proven technology to provide our clients with a perfect starting point – allowing them to realize a fully customized design in a fraction of the time.”

C-Job believes the biggest changes in the maritime industry are going to be provoked by climate change concerns. t

“Climate change, circular economy, new energy sources will dramatically affect the naval business model and drive innovation in an inprecedented manner,” the company says.

”This creates enormous possibilities for designers, shipbuilders and -owners.”
