Sweden’s Erik Thun Is Adding to Dual Fuel Tanker Fleet:
Four LNG-Diesel Ships Built by Netherland’s Ferus Smit
Powered by 34DF Engines with LNGPac Fuel Supply Units

Wärtsilä is providing engines, propellers, and fuel supply systems for four new liquefied natural gas-diesel dual fuel-powered vessels for Thun Tankers, a unit of Lidköping, Sweden-based based Erik Thun AB and member of the Gothia Tanker Alliance.

The 377-foot (115-meter) coastal tankers for Erik Thun will be powered by Wärtsilä 34DF natural gas-diesel dual fuel engines fed by Wärtsilä LNGPac fuel systems.

The 377-foot (115-meter) ice-class 1A vessels will run on both LNG and diesel, Wärtsilä says, “capable of handling the year round sailing conditions in the Baltic Sea.” They are being built at the Scheepswerf Ferus Smit yard in the Netherlands for Sweden based Erik Thun AB.

Wärtsilä is talking up a “next generation” design focused “on high energy efficiency, low noise levels both above and below the water, and environmental sustainability.”

34DF’s Fuel Efficiency ‘a Prime Consideration’

The scope of supply for each of the four ships includes a six-cylinder Wärtsilä 34DF dual-fuel main engine, a Wärtsilä LNGPac fuel supply system, a Wärtsilä GVU/gas valve unit, and a CPP/controllable pitch propeller.

“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 VP Aaron Bresnahan says in a release.

“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 favor.”


“We have worked closely with Wärtsilä on many projects for more than 45 years, and we recognize their technical expertise and the reliability of their products,” Erik Thun managing director Anders Källson says in the Wärtsilä announcement.

“Efficiency and sustainability are the key essentials,” he said.

The Wärtsilä equipment for the four new tankers will be delivered to the yard starting in 2018.

By No Means the First

Wärtsilä notes that in 2014, the Scheepswerf Ferus Smit yard built two cement carriers on behalf of Erik Thun AB. These are now operated by JT Cement; a joint venture company with Norway based KG Jebsen Cement (HHP Insight, June 15, 2016).

“Those ships also feature Wärtsilä dual-fuel propulsion,” the engine provider says, “and this latest order can be seen as an endorsement of both the owner and the shipyard’s satisfaction with the Wärtsilä technology.”

The contract for the four new tankers was signed during the first quarter of this year.
