Description

bound4blue has successfully installed three 22-meter-high eSAILs® on the Ville de Bordeaux, a ro-ro vessel operated by Louis Dreyfus Armateurs (LDA). This milestone represents the first-ever deployment of fixed suction sails on a ro-ro ship owned by a leading European shipowner. Completed in under two days in Vigo, Spain, the installation aligns with Airbus' commitment to reducing CO2 emissions from maritime logistics by 50% by 2030. The eSAILs® enhance propeller efficiency by 20%, showcasing wind-assisted propulsion as a key solution for achieving net-zero emissions by 2050.
bound4blue is advancing this technology with additional agreements for installations on the MV Atlantic Orchard, Odfjell’s chemical tanker, and Eastern Pacific Shipping's Pacific Sentinel. These projects underscore the growing adoption of eSAILs® to cut fuel consumption and emissions across diverse vessel types.

Impact & Result

The Ville de Bordeaux installation is expected to deliver annual savings of 2,705 tons of CO2 and 845.3 tons of fuel—approximately 10%—equating to $591,710 in economic benefits. Results from onboard tests have been officially documented and are in the process of certification by Bureau Veritas, further validating the effectiveness of this innovative technology.

Solution Spotlight

The shipping industry transports 90% of the world’s cargo, resulting in enormous air pollution impacts. Designed as an engine assist technology, the rigid wingsail system is completely foldable to the ship's deck to avoid safety issues during harsh weather conditions or during loading/unloading operations. It is fully automated - no extra crew required - and will orient itself to maximize performances for any wind direction. As a result the wingsails thrust capacity is ten times higher than that of traditional sails and other existing novel designs. By generating effective thrust from wind power, Bound4blue’s rigid wingsails allow vessels to operate at their nominal service speed with reduced engine propulsion, thereby lowering fuel consumption and polluting less.
