Wärtsilä Corporation has been contracted to supply propulsion and fuel supply solutions for four new tanker vessels for coastal tanker operator Thun Tankers, part of Erik Thun AB, of Sweden. Fitted with dual-fuel engines, the vessels will use Liquefied Natural Gas (LNG) and diesel to meet their energy requirements. Ordered in October 2016, the vessels are being build by Scheepswerf Ferus Smit yard in the Netherlands.
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 Wärtsilä 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 Wärtsilä 34DF dual-fuel main engine, a Wärtsilä LNGPac fuel supply system, a Wärtsilä Gas Valve Unit (GVU), and a Controllable Pitch Propeller (CPP) with HP nozzle. The equipment will be delivered to the yard commencing in 2018.
“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,” says, Aaron Bresnahan, Vice President, Sales, Wärtsilä Marine Solutions.
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 Wärtsilä dual-fuel propulsion, and this latest order can be seen as an endorsement of both the owner and the shipyard’s satisfaction with the Wärtsilä technology.
When delivered, the ice-class 1A vessels will be capable of handling the year round sailing conditions in the Baltic Sea.
