Bound4Blue selects gas carrier Helena Kosan for installation of innovative eSail system
Spanish technology company Bound4Blue, specialized in wind-assist propulsion systems, has signed a contract to install its aerodynamic eSail on the gas carrier Helena Kosan. This will be the company’s first project in the gas carrier segment, with installation expected to be completed by 2026.
About the vessel
-
Helena Kosan — Maltese-flagged gas carrier, built in 2007.
-
Owned by BW Epic Kosan.
-
Length: 115 m, beam: 18.6 m, gross tonnage: 7,465 GT.
-
The ship will be fitted with a 24-meter eSail.
Project phases
-
Preparatory work — to be carried out during drydock operations later this year.
-
eSail installation — a fully autonomous plug-and-play wind-assist sail to be mounted in 2026.
About the eSail technology
Bound4Blue’s eSail uses aerodynamic principles to generate additional thrust from wind power. Key features include:
-
full autonomy, requiring no crew input;
-
reduced fuel consumption and emissions;
-
already deployed on tankers, juice carriers, Ro-Ro vessels, ferries, and general cargo ships.
According to Bound4Blue, the Helena Kosan project represents an important milestone in expanding the eSail technology to new vessel types, including gas carriers.
