Wärtsilä has secured a contract to provide engines, propellers, and fuel supply systems for four new tanker vessels, which are set to be owned by Sweden's Erik Thun.

The company will deliver a 6-cylinder 34DF dual-fuel main engine, LNGPac fuel supply system, Gas Valve Unit (GVU), and a Controllable Pitch Propeller (CPP) with HP nozzle for installation on each of the tankers under the new deal.

Deliveries of the Wärtsilä equipment are expected to begin next year.

The ice-class 1A vessels are currently being built at Scheepswerf Ferus Smit yard in the Netherlands and will be deployed in the Baltic Sea.

Each of the 115m-long coastal tankers will feature a ‘next generation’ design focusing on high energy efficiency, low noise levels both above and below the water, and environmental sustainability.

Scheepswerf Ferus Smit yard previously built two cement carriers for Erik Thun in 2014, which also feature Wärtsilä dual-fuel propulsion and are currently being operated by JT Cement.

"The fuel efficiency of the Wärtsilä 34DF engine, whether in gas or diesel mode, was a prime consideration in its selection for these ‘next generation’ tankers."

Wärtsilä Marine Solutions Sales vice-president Aaron Bresnahan said: “The fuel efficiency of the Wärtsilä 34DF engine, whether in gas or diesel mode, was a prime consideration in its selection for these ‘next generation’ tankers.

“Similarly, the successful track record of both the CPP and LNGPac solutions, and the proven efficiencies that they have demonstrated, were convincing arguments in our favour.”

Wärtsilä was selected to provide controllable pitch propellers and Power Take Off / Power Take Home (PTO / PTH) shaft generator systems for two new RoRo vessels last month, which are currently being built at Uljanik shipyard in Croatia.

The vessels will be owned by Luxembourg-based operator CLdN Ro-Ro.
