Te development of new technologies to better protect the environment and meet the demands of new regulations is vitally important in this context and ClassNK is currently supporting a total of 19 projects being undertaken in a Japanese national initiative. Tese include the development of extremely low resistance hull coatings, non hub-vortex propellers, a propeller ttachment to improve thrust efficiency, high efficiency heat recovery systems for small size diesel engines, small-size dual uel diesel engines, hybrid turbochargers for Following the USA decision to accept hybrid power systems.

this LNG FPSO initiative, complemented by the other products, is to serve the industry with a solution to monetise energy resources that otherwise would be untapped and by doing so, to place the company as a pioneer in this market and to maintain a leading position in the long term, in the same way as it did in the crude oil FPSO lease and operate segment, where it is still a significant player today.
