First LPG gas tankers with sails for wind-assisted propulsion

Anthony Veder, a leading gas carrier operator, has completed the first installation of wind-assisted propulsion on an LPG gas carrier, demonstrating the industry’s growing interest in wind-assisted propulsion. It is the first of two planned installations and part of a larger effort by the LNG, ethylene and LPG carrier operator to improve operations and move closer to its goal of being a net-zero emitter by 2035.

“While we focus on optimizing the design of newbuilds and running them on (bio)LNG, we are equally committed to increasing the efficiency of our existing fleet,” said Björn van de Weerdhof, Commercial and Sustainability Director at Anthony Veder. “Wind-assisted propulsion is an important step in this effort, and our collaboration with Econowind reflects the strength of our partnerships. In addition, we are looking at other solutions such as powertrain optimization and joint measures that we can take with our customers, such as lower speeds through just-in-time arrival and the use of shore power.”

Anthony Veder has partnered with Econowind to deploy its VentoFoils on its ships. Rens Groot, Chief Operations Officer at Econowind, reports that Anthony Veder conducted a thorough analysis before selecting the VentoFoils, including an advanced business case calculation that weighs benefits and realistic costs. He said it shows the potential for speed improvements on gas carriers, where VentoFoils would help compensate for limitations in engine performance.

The installation was a retrofit of the Coral patula (8,571 dwt), an ethylene tanker built in South Korea in 2009. The ship is 377 feet (115 meters) long and was equipped with two of the foils. The company also plans to retrofit the films Coral pearl (8,600 dwt) a sister ship, also built in South Korea in 2009. Both ships are registered in the Netherlands.

By retrofitting the two ethylene tankers in his fleet with Econowind VentoFoils, Anthony Veder will use wind energy to significantly reduce ships’ fuel consumption. The system is designed to work in parallel with existing engines, increasing propulsion using the power of the wind.

Based on the wind conditions, the companies estimate that with optimal wind conditions they expect fuel savings of around five percent and a potential of more than 10 percent. By reducing fuel consumption, the company not only reduces energy costs, but also greenhouse gas emissions.
