Wind propelled ship double awarded Bureau Veritas AiP

The AiP was presented to Hyundai Heavy Industries Co. Ltd, Hyundai Global Service Co. Ltd (HHI), TotalEnergies Gas & Power Limited and Mitsui O.S.K. Lines Ltd (MOL), at Nor-Shipping.

Validation

This JDP focused on three wind propulsion technologies, two of which were wing sails and one a rotor sail system.

The principal conclusion of the project and the subsequent issuance of the AiP demonstrate that all of these systems are compatible with existing classification rules and regulations for VLCCs and LNG carriers.

This paves the way for more detailed work to address specific risks that would enable detailed design and arrangement work to proceed.

BV is actively participating in multiple WASP projects, supporting the development of these innovative technologies.

In March 2021, BV released an update to its rule note for WIND PROPULSION SYSTEMS (WPS) – NR 206. Building on pre-existing BV rules released in 1987, the rule note provided classification requirements for modern wind-powered ships.

BV Rule Note NR206 provides load cases and coefficients for all types of wind propulsion technologies, including free standing rigs, wing sails, kite sails, suction sails and rotors, thereby serving as the key classification framework for wind assisted propulsion.
