Wärtsilä says it has launched its new SK 5054 MkII chemical and oil products tanker design at the current SMM conference and exhibition in Hamburg, Germany. The proven Wärtsilä SK 5054 ship design has been used for more than 60 vessels already built and in operation. The SK 5054 MkII version builds upon this strong foundation to offer a reliable and environmentally sound ship design that incorporates the latest Wärtsilä technology applied to its broad offering of solutions. In particular, the new design facilitates the use of gas as a marine fuel, thereby making it especially applicable to ships that will operate within emission control areas (ECAs). This new design offers a 12% increase in energy efficiency over the original SK 5054 design.
