Wärtsilä Powers The World’s First Dual-Fuelled Dredger



‘Scheldt River’ a new generation ‘Antigoon’ class dredger, will be the world’s first dual fuelled dredger powered by Wartsila. Wartsila has patented the LNGPac technology.  This vessel is built by Royal IHC (IHC) in the Netherlands for the Belgium-based DEME Group.

The 104-metre long vessel will have a hopper volume capacity of approximately 8,000 cubic metres.  The scope of supply includes one 12-cylinder and one 9-cylinder Wärtsilä 34DF dual fuelled engines, two Wärtsilä controllable pitch propellers and two transverse thrusters as well as the company’s patented LNGPac gas supply and storage system.  Wärtsilä’s dual-fuel (DF) engines will power the machine by either liquefied natural gas (LNG) or conventional marine fuels.


“Wärtsilä’s unmatched experience and extensive reference list in dual-fuel engine applications, plus our complete solutions portfolio, were key considerations in the award of this contract.  We congratulate the shipyard and owners for taking the decision to have this new dredger become the first to be capable of using LNG or diesel fuel,” says Lars Anderson, Vice President, Engine Sales, Wärtsilä Marine Solutions.

“Environmental considerations are extremely important for every new vessel built today. Operating on LNG allows DEME to set new standards in minimising harmful emissions. “Scheldt River” will easily comply with all local and international environmental regulations.  Wärtsilä’s dual-fuel know-how and, in particular, the 34DF engine series made our concept feasible,” says Jan Gabriël, Head of New Building and Conversion Department at DEME.

Wartsila, the pioneer in LNG marine fuel:

Wartsila, the leader in propulsion solutions for gas-fuelled vessels is a leading supplier of complete lifecycle power solutions for the marine and energy markets.  The company, completely committed to the goal has created in-depth knowledge of the use of natural gas and LNG.  LNGPac, the brainchild of Wartsila, proves its expertise and knowledge of LNG applications, as well as its dedication in making LNG available for all ship operators and owners.

‘Scheldt River’ is the second notable order received by Wärtsilä in recent weeks for dredger related propulsion solutions.  In June, the company was contracted to supply a comprehensive, integrated solutions package for one of the world’s largest and most advanced self-propelled cutter dredgers currently under construction in China.
