World’s first: Wind propulsion on a chemical tanker

In decarbonization efforts for its fleet, Norwegian shipping company Odfjell turned to RISE to investigate different wind propulsion systems. The result: the eSAIL® suction sail system will be installed on a chemical tanker, making it the first tanker vessel in the world to harness this type of technology.

- As a neutral, third party we help validate the fuel saving potential and CO2 emissions of wind propulsion, says Frederik Gerhardt, Lead Naval Architect, Aerodynamics and Wind-Powered Ships at RISE. It is exciting to see that the tanker industry seems to have woken up to this kind of technology.

- Each case and study is unique. Our extensive evaluation of different wind propulsion options for this specific Odfjell vessel and its routes served as decision support.

Wind propulsion has by now become a viable option to reduce fuel costs and CO2 emissions. The eSAIL® system, categorized as a suction sail, is based on the use of a thick aerodynamic profile and smart suction to increase the propulsive efficiency. This technology has significant potential to reduce emissions by harvesting the energy on the ship itself and transforming it directly into a forward thrust.

- We are excited to now take the next step by partnering with bound4blue to implement their pioneering eSAIL® system on one of our chemical tankers, says Jan Opedal, Manager Projects at Odfjell.
