C-Job Launches Self-Propelled Cutter Suction Dredger Design

C-Job Naval Architects recently launched an innovative, new, and customizable Cutter Suction Dredger (CSD) series.

Headlining the series is a 34-inch self-propelled cutter suction dredger that features a 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. The self-propelled CSD boasts a length of 296 feet, which can be extended to provide an increased swing width.

Todd Allen, our VP Business Development at C-Job, says “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.” The CSD series were designed with operators in mind so they are maintenance friendly and safe. This not only protects the crew but it minimizes downtime and maximizes production.

Mid-range solution

The CSD series presents the solution for mid-range cutter suction dredgers featuring a dredge discharge diameter of 20 to 40 inch 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 benefitting 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 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.

Thanks to our experience, designs not only focus on the standard disciplines but can also include design of machinery and piping, dredging equipment, and the integration of sub-suppliers’ systems. This combined with our independence, means that our client are always able to completely tailor their vessel and are not limited to a single equipment vendor. When clients chose a C-Job design, they have the freedom to choose their own engine brand, fuel type, suppliers, and ship yard.

Todd Allen says “Thanks to our independent position and our knowledge of CSDs and dredge equipment engineering, we are able to create designs that increase our client’s competitive edge. Our new CSD series builds on proven technology to provide them with a perfect starting point– allowing them to realize a fully customized design in a fraction of the time.”

Dredge design experience

If you’re curious about projects we’ve worked on previously, check out our track record. For example, we have assisted on the design of the cutter ladder for the ‘General MacArthur’, owned by Callan Marine, as well as the full design scope of the ‘Lorraine Hooks’ on behalf of SPI/Mobile Pulley Works for US dredging company Mike Hooks.
