High-security hydrographic surveys

Summary

The tender concerns a framework agreement for high-security hydrographic surveys in the Gulf of Finland, the Archipelago Sea and the Åland Islands. The work includes collecting depth data using multibeam echo sounders and possibly Bathy-LiDAR, followed by processing the collected data. The results must comply with Traficom quality requirements based on the international IHO S-44 standard. Survey areas include archipelagos and open sea at depths ranging from 2.5 m to approximately 200 m. The estimated value is EUR 20,000,000, but annual orders depend on available funding and some years may have no orders. Applications must be submitted by 30 September 2026 at 09:00 UTC.
