ClassNK, in collaboration with Japanese companies Imabari Shipbuilding and Sayonas Shipbuilding, has started full-scale ship tests to develop a feedback scheme on design for ship performance.

The company, in collaboration with NAPA of Finland, has developed an energy-saving operation support system called ClassNK-Napa Green, which will be installed in vessels during the joint research project to verify its effectiveness.

After getting feedback from the gathered and analysed information, the input will be used to optimise fuel efficiency performance in actual sea conditions.

Shipyards usually use sea trials to confirm performance in calm seas, but performance in actual sea conditions is not usually determined until the ship enters service.

ClassNK said the information gathered during actual operations with the ClassNK-Napa Green system will help in determining the relationship between draught, trim, main engine output, vessel speed and weather data.

The information will be used to develop an upgraded ship design as well as improve performance in actual seas.

If the project is successful, it will help in reducing the ships’ environmental burden and strengthen international competitiveness, according to ClassNK.
