The Estonian ferry company has installed a new type of propeller blade, manufactured by Kongsberg Maritime Sweden, on Baltic Queen, leading to energy savings and even lower underwater noise.

According to initial results, the new equipment saves no less than 14% fuel (Baltic Queen operates on the Stockholm-Tallinn crossing, offering room for 2,800 passengers and 1,130 lane metres for vehicles and wheeled cargo).

At the same time, the acoustic pressure radiated into the water at low frequencies is now at least three times, and at all frequencies combined, at least twice as low vs the old propeller blades.

If further testing corroborates the results, Tallink intends to equip its other vessels with the new propeller blades.

"Every new solution, which helps us as a company to reduce the negative impact on the natural environment around us, is most positive indeed and achieving good results inspires us to find more and more such solutions. Solutions that have a positive effect in multiple ways, such as Baltic Queen's new propeller blades, are particularly pleasing as they reduce fuel consumption, emissions and underwater noise at the same time," said Chef Captain Tarvi-Carlos Tuulik, Head of Ship Management at Tallink Grupp.
