Helping an industry to set sail

PRESS RELEASE Gothenburg 7th July 2022

In response to rapidly growing demand, SSPA expands its services in maritime wind propulsion and introduces the new business segment “Wind-Powered Ships”. A special team of consultants, experts, and naval architects will support the maritime industry with independent guidance and assessments of wind-powered ships.

Reducing fuel consumption High fuel prices and the International Maritime Organization’s policy framework on the reduction of GHG emissions continue to force ship owners and operators to reduce fuel consumption. Various saving measures, actions, and technologies are being investigated around the world. Among them one that has successfully been used for millennia: Wind.





First-hand knowledge

Modern wind propulsion technologies have little in common with the canvas sails of old and range from “Flettner-rotors” over kites and suction sails to rigid sails that resemble vertical aircraft wings. All of these systems are major investments and the decision to install them requires careful consideration of many complex questions. Based on first-hand knowledge and full-scale data, SSPA has developed the methods and tools required to support the industry.


 Above: The Brazilian company Vale recently had rotor sails installed on Sea Zhoushan, one of the largest ships in the world. SSPA was involved from the very start. 


“SSPA was a key player in investigating different wind propulsion systems; their advantages, disadvantages and expected savings leading up to our decision to invest.

̶ Rodrigo Bermelho (Shipping Technical Manager at Vale) ̶
