Spanish company bound4blue has announced that its eSAIL sail technology has achieved average daily fuel savings of 1.7 t/day on the vessel Ville de Bordeaux, owned by Louis Dreyfus Armateurs (LDA). These data were confirmed after one year of operation by Bureau Veritas Solutions Marine & Offshore, an independent entity specialized in maritime efficiency.
According to the results of the analysis, savings peaked at up to 5.4 tons per day, without relying on weather routing strategies. The vessel, chartered by Airbus to transport aeronautical sub-assemblies between Europe and the United States, operates with three 22-meter units installed in 2024.
Compact, adaptable and efficient in varying conditions
[post_relacionado]eSAILs generate significantly more lift force per square meter compared to traditional rigid sails. This efficiency allows for lighter installations with lower deck space requirements, making them ideal for a wide range of vessels, from gas carriers to cruise ships.
Thanks to their ability to operate effectively in side and upwinds, the sails are adaptable to a variety of weather conditions, which broadens their applicability on international routes and high-speed vessels. high-speed vessels.
Environmental and regulatory benefits with short-term payback
The eSAIL eSAIL system enables operators to comply with regulations such as FuelEU Maritime and the EU Emissions Trading Scheme. These regulatory benefits have a direct impact on operational profitability.
With an estimated payback period of less than five years, the solution is positioned as a viable option for retrofit projects on existing vessels and new construction.
International collaboration strengthens energy transition
The Ville de Bordeaux is not the only example. Companies such as Maersk Tankers, Eastern Pacific Shipping and Klaveness have already commissioned the installation of these sails. installation of these sails on ships in on vessels in various segments. bound4blue’s technology is establishing itself as one of the key tools to accelerate the decarbonization of shipping.
Camille Blayo, BVS performance engineer, noted that the methodology employed included advanced energy modeling, real-time data and CFD analysis to ensure accurate results.
These results validate the transformative potential of wind propulsion on operational vessels, without the need for deep structural redesigns.
said David Ferrer, CTO of bound4blue.
Headquartered in Cantabria and with a presence in Barcelona and Singapore, bound4blue has installed its system on six vessels and has more than 50 units in its portfolio. The firm continues to move towards a global fleet that is more efficient, competitive and aligned with international climate targets.
