Classification society Bureau Veritas (BV) has released new-generation classification rules for wind propulsion systems that are expected to help support and drive the development of zero-carbon propulsion options for modern ships.
As informed, the new Bureau Veritas rule notation for WIND PROPULSION SYSTEMS (WPS) – NR 206 , builds on pre-existing BV rules released in 1987.

Now two new notations have been issued to provide the classification requirements for modern wind-powered ships — WPS 1 for standing rigging and WPS 2 for standing and running rigging. Both provide load cases and coefficients for all types of wind propulsion technologies including free-standing rigs, wing sails, kite sails, and wind turbines.
The new rules are said to provide the key classification framework for wind-assisted propulsion. Firstly, at the design review stage, ensuring safety and interactions with other systems onboard are addressed, and, secondly, for in-service life, wherein the rules address survey regime and maintenance requirements.
General requirements that must be addressed include:
In addition, the rules require an operational manual including limitations of operation of wind propulsion systems in accordance with its design, such as wind speed limitations.
“We are pleased to see Bureau Veritas’ continuous involvement and support in innovation and in the decarbonization of shipping with the release of these new rules. These technical guidelines will help us in the development of our Oceanwings and their application on board cargo vessels,” Ludovic Gérard , CEO at AYRO commented.
“We know that the power of the wind, even if it is not always available, can make a significant contribution to GHG-free ship propulsion and ship design. Wind propulsion systems can play a significant auxiliary role in providing substantial propulsive energy and, in some cases, wind could be used for main propulsion requirement,” Laurent Leblanc, Senior Vice President Technical & Operations at Bureau Veritas, said.
“This is an incredibly exciting time for the industry as we revive an ancient, powerful and endlessly renewable source of energy – but with all the benefits of modern technology and materials. Bureau Veritas is currently involved in a wide range of wind propulsion projects and all stakeholders are increasing their understanding as we make progress.”
The classification society is addressing the challenges of sustainability and the energy transition by providing solutions to the safety, risk, and performance requirements for innovation in future fuels and propulsion systems. Forthcoming rules from Bureau Veritas in 2021 will address methanol, ammonia, and hydrogen as marine fuels, including fuel cell applications. Bureau Veritas recently issued ‘NH3 Ready’ approval to GTT related to the containment of ammonia in LNG as fuel membrane tanks.
