Netherlands-based C-Job Naval Architects has launched a new series of cutter suction dredgers (CSDs).

Each 360- by 82-foot (110- by 25-metre) dredger in the series will feature a cutter power of 3,500 hp (2,609 kW) and a total installed power of approximately 26,000 hp (19,388 kW). There will also be two 6,300hp (4,697kW) dredge pumps on deck and one 3,500hp (2,609kW) submerged dredge pump on the cutter ladder, enabling a maximum dredging depth of 95 feet (28.9 metres).

The self-propelled CSD boasts a length of 296 feet ( metres), which C-Job said can be extended to provide an increased swing width.

C-Job added that the CSD series presents a solution for mid-range dredgers featuring a dredge discharge diameter of 20 to 40 inches (0.5 to one metre) and a total installed power from any size up to 30,000 hp (22,370 kW). The design can also be completely tailored to owners’ desired operational profiles.

Options will include self-propelled or stationary service, an anchor boom system, a barge loading system, motion compensation in the spud carrier system, a Christmas tree system, and a spud tilting system to name a few.

In terms of fuel options, in addition to standard systems, designs can also include renewable marine fuel such as methanol or a combination via dual-fuel propulsion.

The CSDs will be US-flagged and classed by ABS.
