Wärtsilä launches new series of LNG carrier designs

MARCH 23, 2015 — The latest addition to Wärtsilä's ship design portfolio is a new series of LNG Carrier designs that the company says is an important part of its strategic program of "Taking Merchant Shipping into the Gas Age."

The series consists of four vessel designs, the WSD59 3K, WSD59 6.5K, WSD55 12K, and WSD50 20K, all developed in cooperation with customers to produce vessels that are appropriate for the global LNG infrastructure and 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 emphasized.

"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 utilized to develop this latest series of world class designs for LNG Carriers," says Riku-Pekka Hägg, VP, Ship Design, Wärtsilä Ship Power. "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."

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 m. 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 m. 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 m.

The new designs have been developed at the Wärtsilä Ship Design offices in China and Poland. They will be featured at the CMA Shipping conference and exhibition being held this week in Stamford, CT.
