LNG-fuelled dredger to set new benchmark

Dutch shipbuilder Royal IHC has successfully launched what it claims as the world’s largest cutter suction dredger (CSD) and the first of the type capable of running on LNG.

Built for Belgium’s DEME, the Spartacus is a self-propelled CSD designed by IHC and is the world’s largest CSD. The 164m long vessel will have a total installed power of 44,180 kW. It will feature four 9-cylinder Wärtsilä 46DF dual-fuel engines capable of running on LNG, HFO or MDO, two 8-cylinder Wärtsilä 20DF dual-fuel auxiliary engines and a Wärtsilä LNGPac fuel gas storage and supply system with a bilobe tank arrangement.


IHC and DEME acquired extensive knowledge during the build of LNG-powered trailing suction hopper dredgers Minerva and Scheldt River. This know-how was invaluable throughout the construction of the Spartacus.

As the first LNG-powered CSD in the world, Spartacus sets a new benchmark in the industry. It also features several additional innovations, such as a waste heat recovery system, a one-man operated dredge control and a heavy-duty cutter ladder that can reach a dredging depth of 45m.

“DEME’s drive to innovate and focus on sustainability is reflected in the company’s multiyear fleet investment programme,” said Director and CEO of DEME Alain Bernard. “The new additions to the fleet are part of our continuous efforts to further increase efficiency, both in terms of production and environmental performance. Spartacus stands out because of her unrivalled power and high-tech features on board. The CSD will drive new levels of performance and provide our customers with flexible solutions for dredging projects in even the most harsh and remote environments.”

IHC’s CEO Dave Vander Heyde is proud of achieving this important milestone in what has been a challenging project: “IHC is known for its willingness to push boundaries to develop and produce high added-value equipment and vessels for our customers. The combination of power, size and innovation makes the Spartacus a perfect example of such a project.

DEME was once the first dredging company to put a ‘jumbo’ dredger in the market which has led to a new generation of dredging vessels. As the Spartacus will soon be the world’s largest and most powerful LNG-powered CSD in operation, DEME will again have set a new standard in the market.”
