Oceanwings - A two-element wingsail installed on vessels which can reduce fuel consumption by up to 45%

Oceanwings is a beyond state-of-the-art rigid wing sail technology that solves the environmental and economic dilemma faced by shipowners: reducing their environmental footprint while remaining profitable. The Oceanwings enables up to 45% savings in vessels’ fuel consumption and a subsequent reduction in CO2 emissions. Shipowners will thereby both decrease their environmental impact so as to abide by the IMO legislation and improve their operating margins. The Oceanwings can achieve such results because of its two-element wingsail that provide unrivalled aerodynamic lift with limited drag and of its unique automated software, AIUTO, that automatically sets up the ideal wing sail angle of attack and camber to maximize its thrust.

Key features

  • Up to 45% savings in vessels’ fuel and a subsequent reduction in C02 emissions
  • Within 5 years, aiming to generate a reduction of more than 500,000 tons of CO2 emissions and the equivalent of 780 million MWh of fossil-free energy


  • Assuming a carbon tax of $60 per ton of CO2, a fuel cost of $600 per ton of fuel and that an Oceanwings saves 640 tons of fuel yearly, the shipowner will save at the end $507,000 per year

Maturity Stage

  • Medium and large scale commercialization
  • Small scale commercialization
  • Initial market commercialization
  • Prototype testing in the real world
  • Prototype testing 1:1 in the lab
