Scheldt River

Wärtsilä has secured an order to deliver its dual-fuel (DF) engines to power a new generation Antigoon-class dredger being built by Royal IHC (IHC) in the Netherlands.

Scheldt River, being constructed on behalf of the Belgium-based DEME, is claimed to be the first dredger to operate on engines capable of using either liquefied natural gas (LNG) or conventional marine fuels.

DEME New Building and Conversion Department head Jan Gabriël said: "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 will deliver one 12-cylinder and one nine-cylinder Wärtsilä 34DF engines, two Wärtsilä controllable pitch propellers and two transverse thrusters.

In addition, the delivery for this new 104m-long vessel covers Wärtsilä’s patented LNGPac gas supply and storage system.

"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 Marine Solutions Engine Sales vice-president Lars Anderson said: "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."

In July, Wärtsilä signed a contract with Tianjin Dredging, part of the China Communication Construction Company (CCCC), to deliver engines and all essential ancillaries for a new, self-propelled cutter dredger.

Under this contract, Wärtsilä will deliver three 16-cylinder Wärtsilä 32 engines and the latest Wärtsilä condition-based maintenance (CBM) system.
