eConowind offers wind propulsion units for sea-going ships. The goal of the units is to reduce costs and CO2 emissions by reduction of used motor power.
The basic technology is like an airplane wing placed vertical. We optimize the airflow by suction, which allow the wing to be really thick to create about 4x more Force than a normal sail.
2 VentiFoils as retrofit on MV Ankie
2 VentiFoils on a flatrack on MV Frisian Sea
We offer the systems inside a container for easy installation, on a flatrack to be handled by the hatchcrane of the ship or as a retrofit on fixed position.
On captains demand, the Ventifoils deploy. Further sailing is done automatically finding the optimal angles relative to the apparent wind. The generated force will be transferred right into the deck and thus helping with propulsion. To maintain the ships speed, the motor power can be reduced.
Depending on the size, the units reduce motor power up to 200, 450 or 750kW.
Flatrack Ventifoil® Unit
eConowind offers a third innovative foldable and autonomous unit for wind-assisted ship propulsion, helping to propel a variety of coastal vessels.
The eConowind Flatrack unit is based on ISO-fix corners and can quickly be placed and removed. Giving a flexible solution for a variety of vessels such as general cargo vessels or other vessels. The Flatrack system has the advantage to be moved with the hatch crane of the vessel, no additional harbour equipment is needed to move the flatrack system, which provides flexibility in use.
Flatrack Ventifoil® Unit
eConowind offers and provides in the placement of Ventifoils which are fixed to a vessel. in contrast to the eConowind-unit where the ventifoils are placed inside a 40ft container, the size of the foils are not limited to a container.
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.
Containerized eConowind Unit
eConowind offers an innovative foldable and autonomous unit for wind-assisted ship propulsion, helping to propel a variety of coastal vessels.
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).
