Wärtsilä has received an order to supply a comprehensive solutions package for[ds_preview] a series of LNG carriers. The »Dragon 27500« vessels for the Danish operator Evergas are being built at the Sinopacific Offshore and Engineering (SOE) shipyard in China. In addition to LNG, the ships will be able to carry and re-liquefy Ethane and LPG with the cargo handling package supplied by Wärtsilä. Furthermore, Wärtsilä will supply the dual-fuel engines and propulsion equipment. Efficiency and fuel savings are also gained through the Energopac rudder, which lowers resistance and increases propulsion power because it streamlines the water flow from the propeller.
The vessels will operate primarily on LNG using dual-fuel engine technology. This technology also provides operational flexibility and redundancy, since it allows to utilize various conventional fuels in addition to LNG. The integrated LNG fuel system enables the vessel to operate on natural gas independently of the cargo carried. Engineering and delivery of the complete cargo plant in combination with the gas fuel supply system and propulsion plant enables Wärtsilä to optimize the vessel’s complete energy consumption. This is well demonstrated where the LNG supply system is integrated with the cargo handling system so that it may cool the cargo.
