Finland : Next generation tankers to be powered by Wartsila dual-fuel engines.

The technology group Wartsila has been contracted to supply the engines, propellers, and fuel supply systems for four new tanker vessels. The ships will run on both liquefied natural gas (LNG) and diesel, and are being built at the Scheepswerf Ferus Smit yard in the Netherlands for Sweden based Erik Thun AB. The order with Wartsila was booked in the first quarter of 2017.

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. Those ships also feature Wartsila dual-fuel propulsion, and this latest order can be seen as an endorsement of both the owner and the shipyards satisfaction with the Wartsila technology. The 115 metre long coastal tankers feature a next generation design focusing on high energy efficiency, low noise levels both above and below the water, and environmental sustainability. The Wartsila solutions were selected primarily because they meet all these criteria. The full scope of supply for each of the four vessels includes a 6-cylinder Wartsila 34DF dual-fuel main engine, a Wartsila LNGPac fuel supply system, a Wartsila Gas Valve Unit (GVU), and a Controllable Pitch Propeller (CPP) with HP nozzle. The equipment will be delivered to the yard commencing in 2018.

A notable feature of the Wartsila fuel system to be supplied is its open type Tank Connection Space (TCS) that allows natural ventilation. The benefits of this system are its reduced weight, a combined cargo heating medium that controls the temperature both inside the TCS as well as for evaporating the LNG, less installation work for the yard, and a reduced power supply requirement.

The fuel efficiency of the Wartsila 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, says, Aaron Bresnahan, Vice President, Sales, Wartsila Marine Solutions.

We have worked closely with Wartsila on many projects for more than 45 years, and we recognise their technical expertise and the reliability of their products. We are pleased, therefore, to have Wartsila as a partner for this project where efficiency and sustainability are the key essentials, says Anders Kllson, Managing Director, Erik Thun AB.

When delivered, the ice-class 1A vessels will be capable of handling the year round sailing conditions in the Baltic Sea.
