Wind-assisted shipping fleet surpasses 100 vessels worldwide

The global wind-powered commercial fleet has crossed the 100-vessel mark, highlighting the growing role of wind propulsion technology in shipping’s decarbonization efforts. Data cited by The Maritime Telegraph from the International Windship Association (IWSA) shows that more than 100 cargo ships, representing over 5 million dwt, now operate with wind-assist systems.

The fleet includes over 230 wind propulsion units, ranging from rotor sails and wing sails to suction sails, traction kites, and traditional sail technologies. Together, these installations are expected to cut annual carbon emissions by more than 100,000 tonnes.

Growth has accelerated rapidly. In May 2022, only 21 large commercial vessels used wind-assist propulsion. Since then, the fleet has expanded nearly fivefold as shipowners increasingly turn to fuel-saving technologies that also support compliance with stricter environmental regulations.

Tankers currently account for the largest share of installations, with 37 vessels equipped with wind propulsion systems. Bulk carriers and ro-ro or ro-pax ships follow with 24 vessels each, while 19 general cargo ships have also adopted the technology.

According to the IWSA, years of operational testing and proven performance have strengthened industry confidence in wind-assisted propulsion. Market projections indicate the global fleet could reach approximately 200 large commercial vessels by mid-2027 if current growth trends continue.
