Sunday, June 30, 2024 Nordic shipping giant Tallink Grupp recently analyzed the initial results of the latest technical upgrade to its Tallinn-Stockholm route vessel, Baltic Queen. The upgrade has resulted in a significant 13% increase in energy efficiency, meaning the amount of fuel needed to travel one nautical mile has reduced by 13%, along with a corresponding reduction in emissions over the past nine months. The technical upgrade, performed during the ship’s regular docking in Naantali, Finland last September, involved replacing the vessel’s propeller blades with new, innovative ones designed and manufactured by Kongsberg Maritime Sweden AB, a subsidiary of global maritime technology experts Kongsberg Maritime.
These blades were specifically designed for this type of ship, considering the speed ranges required for its operation, thereby enhancing the efficiency of the ship’s propulsion system according to its operational needs. Additionally, underwater analyses conducted in autumn 2023 showed a reduction in underwater noise generated by the ship. The results of this upgrade, combined with other technical and operational measures to reduce Baltic Queen’s environmental impact, have elevated the ship’s Environmental Ship Index (ESI) to a level comparable with the company’s newest and most environmentally friendly dual-fuel shuttle vessels, Megastar and MyStar.
With Baltic Queen’s ESI now exceeding 94 points out of a maximum of 100, this achievement has also le.
