Wärtsilä has released a new series of LNG carrier ship design as part of its strategic programme to take merchant shipping into the gas age.
The series is made up of four vessel designs, the WSD59 3K, WSD59 6.5K, WSD55 12K, and WSD50 20K, which have been developed with customers to produce vessels that are appropriate for the international LNG infrastructure and applicable for ocean going and inland water operations.
Wärtsilä states that fuel economy, performance guarantees, optional versions to meet specific needs, and the flexibility to choose particular features and solutions have been focused on for each design.
“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 been constructed so fare based on Wärtsilä designs, including some of the most advanced LNG-powered ships in the world.
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. 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.
