Baltic Queen Ferry Undergoes Innovative Environmental Upgrades in Finland

Baltic Queen Sets Sail into Eco-Friendly Waters with Technological Advancements and Noise Reduction Initiatives


The passenger ferry Baltic Queen, operated by Tallink Grupp on the Tallinn-Stockholm route, recently underwent scheduled technical maintenance in Naantali, Finland. In addition to various hull and interior works, the vessel underwent significant technological upgrades and environmentally friendly renovations. One of the key improvements involved the replacement of the propeller blades with innovative designs aimed at enhancing efficiency and reducing underwater noise.

In collaboration with Tallinn University of Technology (TalTech), a comparison of underwater noise levels before and after the modification was conducted. The results revealed a remarkable reduction in underwater acoustic pressure, with low-frequency pressure at least three times lower and an overall decrease of at least half across all frequencies.

Tarvi-Carlos Tuulik, Chief Ship Management and Chief Captain at Tallink Grupp, expressed satisfaction with the outcomes. “Every new solution that helps our company reduce its negative impact on the natural environment is highly positive, and achieving good results inspires us to explore more solutions of this kind. Formats that have a positive impact in multiple ways, such as Baltic Queen’s new propeller blades, are particularly gratifying as they simultaneously decrease fuel consumption, emissions, and underwater noise,” Tuulik stated.

The newly designed blades were custom-made by Kongsberg Maritime Sweden specifically for this type of vessel. Anticipated fuel and emission savings are expected to be at least 14%. If proven successful, Tallink Grupp plans to extend the use of these innovative propellers to other ships in their fleet.

The environmentally conscious upgrades align with Tallink Grupp’s commitment to sustainability and environmental responsibility. As maritime industries continue to seek eco-friendly solutions, the successful implementation of these innovations on the Baltic Queen sets a promising precedent for the broader adoption of such technologies within the maritime sector.
