Wärtsilä is expanding its offering with a new series of LNG carrier ship designs, part of the company's strategic programme of ‘Taking Merchant Shipping into the Gas Age’.

This latest 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 to produce vessels that are appropriate for the global LNG infrastructure and applicable for both ocean going and inland water operations.

“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," said Riku-Pekka Hägg, vice president, ship design, Wärtsilä Ship Power.

The WSD59 3K design, which has a design draft of 4.75m, is said to offer fuel consumption of 7.5 tonnes per day at a service speed of 14 knots. The fuel consumption for the WSD55 12K design vessels, with a design draft of 6.2m, is 13.5 tonnes per day at a service speed of 14.5 knots, making it the best in its class.

The fuel consumption for vessels based on the WSD50 20K design is also said to be the best in its class at 18.1 tonnes per day at a service speed of 15 knots, while the WSD59 6.5K design offers a fuel consumption of 11.0 tonnes per day at a speed of 13 knots and with a design draft of 5.8m.

Wärtsilä's new designs were developed at the its Ship Design offices in China and Poland
