In light of the situation, ClassNK has developed its Guidelines for Wind-Assisted Propulsion Systems for Ships in order to contribute to the safe integrity and design of this technology and the ships that are installed with it. In addition to verifying structural strength, outlining methods for proving structural integrity of strength members, and utilising calculation methods for load amounts, the guidelines provide class notations for ships whose equipment is designed and installed in line with the guidelines. The contents of the guidelines will be consistently revised in following the developmental progress of the related technology.

Speaking on the occasion, Hayato Suga, Corporate Officer and Director of Plan Approval and Technical Solution Division said “Once wind was the main source to propel ships and technology utilising wind is emerging again to energise ships’ environmental performance. There are a variety of concepts for wind-assisted propulsion systems, ClassNK has materialised its expertise to minimise potential risks by their installations to hull structure, crew, and surrounding environment. To promote the safety and soundness of designs applying wind-assisted propulsion system, we will keep on updating our guidelines in line with further technology progress as well as providing the certification on individual systems or concepts.”

The Guidelines for Wind-Assisted Propulsion Systems for Ships are available to download free of charge via ClassNK’s website.
