Ships can save time by using a tunnel thruster for lateral maneuvers instead of sharp turns. However, the presence of tunnel openings in the thruster increases the vessel’s resistance by 8%, leading to higher energy consumption and CO2 emissions.

To address this challenge, Team-Wärtsilä has developed a solution where the tunnel openings will only be opened when necessary. By keeping the tunnel partially closed while the ship is moving forward, the extra energy required can be saved. This development is a significant step towards achieving the shipping industry’s target of reducing CO2 emissions by 40% by 2030 and 70% by 2050, as required by shipping regulations.
