Engineering firm ABB and wind propulsion specialist Econowind have combined weather routing technology with wind-assisted propulsion systems to help vessel operators reduce bunker fuel consumption, according to Ship & Bunker.
According to Ship & Bunker, ABB confirmed on its website that its routing technology is now working alongside Econowind’s VentoFoil wind propulsion system to make better use of favourable wind conditions during voyages.
How the Technology Works
The VentoFoil system generates forward thrust from wind, according to Ship & Bunker, allowing ships to hold their speed while relying less on engine power. Depending on weather conditions, the outlet reports that the technology can cut bunker fuel consumption by 6-10%.
ABB’s routing software complements this by analysing weather forecasts and voyage data, helping crews select routes that make the most of wind propulsion benefits throughout a voyage, Ship & Bunker reports.
Scale of the Partnership
The collaboration between ABB and Econowind began in 2025 and has since expanded to cover roughly 150 VentoFoil units installed across about 50 vessels, according to Ship & Bunker. ABB also stated that its SPOS weather routing system is already in use on more than 4,500 ships globally.
Regulatory Angle
According to Ship & Bunker, the companies noted that pairing wind propulsion with route optimisation can support shipowners in meeting tightening environmental regulations. Reduced fuel consumption may help improve compliance with the IMO’s EEXI and CII requirements, while also lowering emissions-related costs under the EU Emissions Trading System and FuelEU Maritime rules.
Does This Matter to You?
For those tracking fuel efficiency technologies and emissions compliance strategies, this development illustrates how combining operational tools—such as weather routing—with hardware solutions like wind-assist systems can produce measurable reductions in bunker fuel demand. Lower fuel consumption on vessels equipped with such systems could translate into reduced bunker purchasing volumes and altered voyage planning considerations for operators managing EEXI, CII, EU ETS, and FuelEU Maritime obligations.
The source material does not specify vessel types, trade routes, or cost implications beyond the stated fuel savings range, so the broader commercial impact across different fleet segments remains unclear based on available reporting.
