Wind-assisted boxship project moves ahead

Zéphyr & Borée has received an approval in principle (AiP) from class society Bureau Veritas for an open-top 1,800 teu containership that demonstrates the feasibility of using wind-propelled wing-sails on this type of vessel.

The 185 m long container vessel is equipped with shaft generators and a heat-recovery system that minimise fuel consumption. Its propulsion system is augmented by eight thick, asymmetrical wing-sails, provided by CWS (Computed Wing Sail), that can be steered to catch port and starboard winds, and adjust themselves automatically depending on wind conditions. The system is compliant with IMO Tier III standards.

The AiP confirms the design’s compliance with the most recent Bureau Veritas notations, including NR 206 on wind-propulsion systems.

Laurent Leblanc, senior VP, technical & operations at Bureau Veritas Marine & Offshore, commented: “Wind, even if it is not always available, is a serious option to help decarbonise the shipping industry. Wind-propulsion systems can play a significant role by providing substantial propulsive energy. With this AiP, we are pleased to demonstrate the technology can be applied to containerships, which represent 17.5% of the global fleet in tonnage.”
