Bureau Veritas, a classification society, has granted approval in principle to Hyundai Heavy Industries Co., Hyundai Global Service CO., TotalEnergies Gas & Power, and Mitsui O.S.K. Lines (MOL) for wind-assisted ship propulsion (WASP) on a VLCC and an LNG carrier, as reported by Offshore Energy.

Wind propulsion technology

At the Nor-Shipping conference in Oslo, Bureau Veritas awarded approval in principle to Hyundai Heavy Industries, Hyundai Global Service, TotalEnergies Gas & Power, and Mitsui O.S.K. Lines for wind-assisted ship propulsion (WASP) on a VLCC and an LNG carrier. The companies conducted a joint development project focusing on three wind propulsion technologies, including wing sails and a rotor sail system. The project confirmed the compatibility of these systems with existing classification rules and regulations for VLCCs and LNG carriers. This milestone allows for further detailed work to address specific risks and proceed with detailed design and arrangement. Bureau Veritas actively supports multiple WASP projects and released an updated rule note for Wind Propulsion Systems in March 2021.

Safe integration

Bureau Veritas has established dedicated rules that serve as a classification framework for wind-assisted propulsion. These rules ensure the safe integration of wind propulsion systems during the design review stage and provide guidelines for survey regimes and maintenance requirements throughout the vessel’s operational life. Additionally, Bureau Veritas granted Approval in Principle (AiP) to CRAIN Technologies for their suction wing SW270, an auxiliary wind propulsion device for cargo ships, demonstrating their support for innovative nautical applications.
