Bureau Veritas delivers AiP for ‘Solid Sail’ to help reduce large cruise ship emissions

Bureau Veritas (BV), a world leader in testing, inspection, and certification has delivered an Approval in Principle (AiP) to Chantiers de l'Atlantique for their innovative sailing propulsion system, Solid Sail, tailored for the large ships market. 

Solid Sail is a 1,200 m² rigid sail made of composite panels assembled together, which was developed specifically for large vessels. The system overcomes the usual size limitations of standard fabric sails. Moreover, the rigidity of the sail panels induces less flapping and therefore increases the estimated life compared to a soft sail.

BV has been involved from the early stage. We delivered the AiP in line with our Rule Note for WIND PROPULSION SYSTEMS (WPS) – NR 206. We conducted an assessment of the Solid Sail’s design and system. This AiP assures the industry that this new technology can be safely used and is ready for the next phase of its development and installation on-board.

Increasing the energy efficiency of cruise ships and lowering their impact on the environment are two of the main objectives of “Ecorizon®”, Chantiers de l’Atlantique’s R&D pioneering 14-year old program dedicated to ship energy and environmental efficiencies. This final validation step paves the way for the commercialisation of Solid Sail and its installation on large cruise ships.

Laurent Leblanc, Senior Vice President Technical & Opreations at Bureau Veritas Marine & Offshore, commented: “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. We are pleased to deliver this AiP to Chantiers de l’Atlantique bringing trust in wind propulsion systems and to support the GHG emission reduction of shipping more generally. That’s how we can help shape a better maritime world. We look forward to seeing the system in operation.”
