Wärtsilä Expands LNG Carrier Design Portfolio

 Wärtsilä has ushered in a new series of LNG Carrier ship designs as part of its strategic programme under the theme “Taking Merchant Shipping into the Gas Age”.

The series comprises four vessel designs, the WSD59 3K, WSD59 6.5K, WSD55 12K, and WSD50 20K, all of which have been developed in close cooperation with customers and are applicable for both ocean going and inland water operations. In each case, fuel economy, performance guarantees, optional versions to meet specific needs, and the flexibility to choose particular features and solutions have been emphasised,  Wärtsilä said.

“Wärtsilä Ship Design has an extensive reference list dating back to 2003 for vessel designs for LNG fuelled 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.

More than 4000 vessels have thus far been built based on Wärtsilä designs, including some of the world’s most advanced LNG powered ships.

Design characteristics:

  •  The WSD59 3K design offers fuel consumption of 7.5 t/d at a service speed of 14 knots. The design draft is 4.75 metres.
  • 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 metres.
  • 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.
  • 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 metres.
