ClassNK has granted an Approval in Principle (AiP) based on its 'Guidelines for Wind-Assisted Propulsion Systems for Ships' and related regulations for the basic design of a hard sail system, which converts wind energy to propulsive force with a telescopic hard sail, and is a fundamental technology of the Wind Challenger Project spearheaded by Mitsui OSK Lines (MOL) and Oshima Shipbuilding.

Along with other participating organizations, MOL and Oshima Shipbuilding have played a central role in research and development on the Wind Challenger Project, which aims to reduce GHG emissions by using wind energy.

ClassNK released its Guidelines for Wind-Assisted Propulsion Systems for Ships in September 2019 in order to contribute to the safe integrity and design of this technology and the ships that are installed with it.

Upon receiving the application from MOL and Oshima Shipbuilding, ClassNK has reviewed the basic design of the hard sail system in line with relevant international conventions, ClassNK rules, and the above-mentioned guidelines. Following its successful completion, ClassNK granted an AIP for the basic design of the hard sail system, which marks the first AIP based on the guidelines.

ClassNK will continue to support the smooth implementation of new technologies through its role as a third-party certification body.
