Wärtsilä, the Finnish engine manufactuer and ship design specialist has unveiled today a new series of LNG carrier ship designs to compliment its portfolio of LNG fuel solutions.

The series comprises four vessel designs, the WSD59 3K, WSD59 6.5K, WSD55 12K, and WSD50 20K, all developed in close cooperation with customers in order to produce vessels that are appropriate for the global LNG infrastructure and applicable for both ocean going and inland water operations.

“Wärtsilä Ship Design has an extensive reference list dating back to 2003 for vessel designs for LNG fueled ships. The experience and know-how that has been built up during these 15 years has been utilised to develop this latest series of world class designs for LNG Carriers. The entire concept of these designs is to enable the lowest possible fuel consumption, to allow owners to select the ship design that exactly meets their needs, and to provide shipyards with the most convenient and cost effective packages possible,” says Riku-Pekka Hägg, Vice President, Ship Design, Wärtsilä Ship Power.

According to Wärtsilä, the WSD59 3K design offers fuel consumption of 7.5 t/d at a service speed of 14 knots and a design draft is 4.75 meters. The fuel consumption for the WSD55 12K design vessels is 13.5 t/d at a service speed of 14.5 knots, making it the best in its class. The design draft is 6.2 meters. The fuel consumption for vessels based on the WSD50 20K design is also the best in its class at 18.1 t/d at a service speed of 15 knots, while the WSD59 6.5K design offers a fuel consumption of 11.0 t/d at a speed of 13 knots. The design draft is 5.8 meters.

More than 4000 vessels have far been built based on Wärtsilä designs, including some of the world’s most advanced LNG powered ships. According to Mr Hägg; “Our ship designs consistently raise the bar for merchant shipping in terms of efficiency and environmental sustainability.”

The new designs have been developed at the Wärtsilä Ship Design offices in China and Poland. Wärtsilä says the series of designs is an important part of the company’s strategic “Taking Merchant Shipping into the Gas Age” program.
