Bureau Veritas (BV) has awarded an Approval in Principle (AiP) to Chantiers de l’Atlantique for its sailing propulsion system, Solid Sail, tailored for the large ship market.
Solid Sail is a 1,200 sq m rigid sail made of composite panels assembled together. The system is claimed to overcome 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.
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, BV said.
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 14-year old programme 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.
Frédéric Grizaud, Chantiers de l’Atlantique Senior Vice President, said: “The concept of Solid Sail is the first of its kind, and is the most advanced and innovative solution of sailing propulsion of the large ships market.
“The integration on board a passenger ship of such an innovative solution is only possible thanks to the tremendous collaborative work done with Bureau Veritas on its new rules on Wind Assisted Propulsion,” he said.
Laurent Leblanc, BV Marine & Offshore’s Senior Vice President Technical & Operations, added: “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 supporting 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,” he concluded.
