Wouter Witzel, with sales offices in North and South America, will supply butterfly valves to two Liquefied natural gas (LNG) powered ferries. Ordered by a Swedish customer, the Chinese Shipyard CSSC Offshore & Marine Engineering Group Company Ltd. (Formerly known as Guangzhou Shipyard International Ltd.) will build 2 cooled LNG powered ferries.
The ferries will hold 1,650 passengers and connect the Swedish mainland with the island Visby. The ships will be of the ´Roll-on-roll-off’ or RoRo variety, a ship-type with 1 or more, open or coverable, horizontal decks, which makes it possible for the ferries to carry a variety of rolling cargo, like cars and trucks.
These LNG ships will be delivered in 2017. The shipping company and the shipyard have, during the design phase, focused efforts on creating an optimal hull with the best possible energy usage and to limit the environmental impact.
