bound4blue, key player in the wind propulsion sector, has successfully installed two 17m-high eSAILs®on Dutch flagged EemsTraveller, a 2,850dwt general cargo vessel owned by Amasus, which set sail on her first voyage on 4 July 2023.
The eSAIL system, categorized as a suction sail, is based on the use of a thick aerodynamic profile andsmart suction to increase the propulsive efficiency, resulting in a system that produces seven times more lift than an airplane wing.
These sails represent a new and improved generation of the system installed on the La Naumon, delivering higher efficiency with the same size.
Standing at a height of 17m, they continue to hold the record as the largest suction sail ever built and installed on a ship. In fact, the installation of these two sails on EemsTraveller also marks the largest installation of fixed suction sails on a ship to date.
The installation was executed in two distinct phases. A year ago, during a scheduled regular dry-dock of the vessel, the foundations for the eSAILs® were manufactured and installed in The Netherlands.
The verticalization manoeuvre and connection to the reinforcement of the sails was completed in less than four hours at the Port of Bilbao last week.
In between these two phases bound4blue has been monitoring the ship to obtain its baseline performance, which will be used by a third party to assess the fuel and emission savings results in the next 12 months.
Scientifically validated results are obtained, which can be used to demonstrate the actual effects of the system in use on board of the vessel and form the basis for any future further development.
