The eConowind unit is based on a 40 ft sea container and can quickly be placed and removed. Giving a flexible solution for a variety of vessels such as general cargo vessels, tankers or other vessels with room for one or two 40 ft sea container(s).
The Ventifoil is a wing shaped element using modern innovations in aerodynamics creating high propelling force relative to its size. Smart suction is integrated in the wing, resulting in double the force of the Ventifoil while reefing when needed.
The Ventifoils can be rotated automatically to find the optimal angles relative to the apparent wind. The generated force will be transferred right into the deck and thus helping with propulsion of the vessel. To maintain the ships optimal speed, the engine power can be reduced.
In heavy and/or unfavourable wind conditions the Ventifoils can be easily stored in the container.
All equipment, like hydraulics, automation and ventilation are integrated in the containerised unit. The only support of the vessel to the unit is 400-460 V, 3 phase, 50-60 Hz power connection.
Currently a prototype is being tested on sea (picture), after an optimization step with the prototype, production can start mid 2019.
