90% of the goods we consume are, at one time or another, transported by ship. Maritime transport really is at the heart of our economy and its decarbonisation has become of major importance. The International Maritime Organization is now calling on the sector to reduce greenhouse gas emissions by at least 50% by 2050.

3 questions for Gildas Quemeneur

Our simulations have demonstrated CO₂ reductions of up to 35% on one section of the transatlantic route.
Gildas Quemeneur, initiative leader de WISAMO

How can your innovation play a role in preserving the marine environment?

The WISAMO wing sail can give 20% fuel savings, and thereby lower CO₂ emissions by the same amount. This level can be increased further depending on the wind and the routes used. Our simulations have demonstrated CO₂ reductions of up to 35% on one section of the transatlantic route.

Where do you stand with regard to other players who are innovating in wind energy?

WISAMO stands out from other solutions due to the flexibility and robustness of the wing sail, which is fully retractable thanks to a control system developed by Michelin’s R&D teams. Its ease of use means no specific training is needed; crews are therefore not impacted in their day-to-day operations.
Furthermore, the profile of the WISAMO wing sail permits optimal upwind performance from 20 to 30 degrees*.


*The wing sail’s profiled shape means it is efficient when sailing almost directly into the wind.

The connection between tires and an inflatable sail is far from being obvious to begin with. Can you spell it out for us?

Developing the WISAMO wing sail called on the Group’s innovation and its proven track-record in high-tech materials expertise; in particular in the field of inflatable structures. This initiative also illustrates Michelin’s growth ambitions beyond tires, as heralded by the new ”Michelin in motion” strategic plan. Finally, maritime transport decarbonization is faithful to Michelin’s All Sustainable vision: by using sea freight to transport its tires, the Group aims to minimize the environmental impact of its supply chain.
