Wärtsilä has launched a new series of LNG carrier ship designs, as part of a strategic programme titled Taking Merchant Shipping into the Gas Age.
The four new vessel designs are WSD59 3K, WSD59 6.5K, WSD55 12K, and WSD50 20K.
These designs have been developed to construct vessels that are appropriate for the global LNG infrastructure and applicable for both ocean-going and inland water operations, the company stated.
Wärtsilä ship power ship design vice-president Riku-Pekka Hägg said: "Wärtsilä ship design has an extensive reference list dating back to 2003 for vessel designs for LNG-fuelled ships.
"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 in this series has a draft of 4.75m and is said to offer fuel consumption of 7.5 tonnes a day (t/d) at a service speed of 14k. WSD55 12K vessels will be capable of cruising at a speed of 14.5k, with the fuel consumption at 13.5t/d.
The vessels based on the WSD50 20K design will have a fuel consumption of 18.1t/d at a service speed of 15k, while the WSD59 6.5K design offers a fuel consumption of 11t/d and a speed of 13k. The design draft of WSD59 6.5K is 5.8m.
The new plans were developed at the Wärtsilä Ship Design offices in China and Poland.
