C-Job Naval Architects: Customizable TSHD series

C-Job Naval Architects is launching an in-house developed trailing suction hopper dredger (TSHD) series – aimed to filling the gap between standard designs and fully tailored vessels. 

The TSHD Fleet features maintenance, multifunctional, and capital dredgers each with varying hopper capacity. Each design in the C-Job series is modular. It can be used as is or adapted to even better suit the intended operations, the company said.

Commenting the latest news, Basjan Faber, C-Job Naval Architects CEO, said: “The C-Job TSHD Fleet offers the benefits of both a standard design combined with a fully tailored design and the opportunities it presents.”

“We’ve noticed a mismatch where off-the-shelf TSHD designs will not match specific project profiles, while fully tailored dredgers can be seen as limiting itself to the type of project it can perform. Plus, any small adaptions to standard designs usually require a hefty fee. In comes the customizable C-Job TSHD series.”

Modular options of the C-Job TSHD Fleet include modifying main parameters in addition to dredging operations and functionalities such as dredging depth, type of dredge pump, pump power, and discharge method.

Additionally, the TSHD series allows for easy up- or downscaling of the hopper capacity ensuring any m3 size is made possible. All dredgers within the C-Job series will feature a Green Passport and Clean Design notation.

Eco-friendly features

The first concept design released from the C-Job TSHD series is a 14,000 m3 multifunctional dredger.

The dredger is optimized for shallow water performance and features two (extendable) suction pipes, self-unloading systems, and eco-friendly features.

“The C-Job design philosophy has always been that a client should be closely involved in the entire ship design process, as it benefits the end product. We’re excited to take this philosophy to the next level and provide ship owners with our new and unique modular series. The C-Job TSHD fleet allows customization while reducing engineering time. A win-win situation for our clients,” added Faber.

The automation process supporting the C-Job TSHD series ensures any proposed changes can be quickly checked. The system will show how changes will alter the design and whether it is indeed feasible almost immediately.

The company’s research into hydrogen-based renewable fuels offers another possible customization element to C-Job TSHD series for its customers.

Basjan Faber also added that “in order to reduce greenhouse gas emissions in the maritime industry, we must consider hydrogen-based renewable fuels. With technology progressing at an ever-increasing rate, what isn’t possible now – may be possible in five years’ time. Especially as it becomes more readily available and affordable.”

“At C-Job we aim to show these possibilities in our TSHD series and share our vision of the future of dredging with our clients.
