ClassNK issues Approval in Principle (AiP) for a Liquified CO\u2082 Carrier installing Wind-Assisted Propulsion System<\/p>\n
Shipping: Emission Possible<\/p>\n
ClassNK has issued an Approval in Principle (AiP) for a Liquified CO\u2082 carrier installing the \u2018Wind Challenger,\u2019 a hard sail wind propulsion system. The ship is jointly developed by Mitsui O.S.K. Lines, Ltd. (MOL) and Samsung Heavy Industries Co., Ltd. (SHI). The AiP confirms the feasibility of the ship\u2019s design from the perspective of applicable rules and safety requirements. A certificate handover ceremony was held at Sea Japan 2026.<\/p>\n

As a solution for responding to the environmental regulations and fuel cost reduction, the implementation of wind-assisted propulsion systems (WAPS) has been progressing. When such systems are installed on board ships, they are expected to be effective in reducing CO\u2082 emissions, etc., by taking advantage of wind power. To support the safe implementation of these technologies, ClassNK published the \u201cGuidelines for Wind-Assisted Propulsion Systems for Ships\u201d as a standard for wind-assisted propulsion systems and ships equipped with these systems.<\/p>\n

ClassNK carried out a review of the conceptual design of the ship based on its \u2018Rules and Guidance for the Survey and Construction of Steel Ships\u2019, \u2018Guidelines for Wind-Assisted Propulsion Systems for Ships (Edition 2.2)\u2019. In addition, ClassNK participated in the risk assessment through HAZID from a regulatory and technical perspective to examine the combined risks arising from the ship\u2019s unique design elements \u2014such as the fore accommodation, liquefied CO\u2082 cargo, and multiple units of the Wind Challenger\u2014 and validated the results of the assessment. Upon confirming the results and that the prescribed requirements had been met, ClassNK issued AiP.<\/p>\n
ClassNK will continually strive to contribute to advanced decarbonization initiatives through safety assessments and more.<\/p>\n
