Chemship has returned to Econowind, a Dutch supplier of wind-assisted ship propulsion systems, to install VentoFoils on two additional vessels as it steps up efforts to cut fuel consumption and emissions.
The company said Chemical Contender and Chemical Fighter will each be fitted with four 16-metre ATEX-certified VentoFoils in the second half of 2026.
The repeat order follows the installation of the same system on Chemical Challenger in early 2024, which Chemship described as the first chemical tanker to operate with wind-assisted propulsion.
“We are pushing ahead on sustainability in every area of our business,” said Niels Grotz, CEO of Chemship. “I am a firm believer in net-zero shipping. The results of the VentoFoils on the Chemical Challenger speak for themselves. Combined with our fuel optimisation software, VentoFoils has reduced fuel use by up to 15%. The installation of VentoFoils on two more ships shows we are making meaningful progress towards a cleaner shipping future.”
Chiel de Leeuw, chief commercial officer at Econowind, said: “Chemship has shown leadership by being the first chemical tanker operator to embrace wind-assisted ship propulsion and demonstrate what is possible in sustainability. We are proud to support their vision and, of course, to see an existing customer return. This repeat order is a strong endorsement of our technology and inspires others to explore proven solutions that reduce fuel use and lower emissions.”
Chemship said the installations will support compliance with FuelEU Maritime and form part of a broader efficiency programme that also includes hull coatings, lubricants and propulsion upgrades.
