The proposed project includes the implementation of innovative technologies /high-frequency radar systems/ to ensure continuous real-time monitoring of the main hydrometeorological parameters ensuring the safety of ships in ports, roadways and approaches to ports, which will allow easier tracking of pollution sources of the sea water area in the approaches to the ports of Varna and Burgas. The implementation of a Bulgarian high-frequency (HF) radar surveillance network is in line with WMO GEO recommendations and will support the protection of the marine environment and coasts, provide protection of coastal infrastructure, as well as improve knowledge and understanding of marine and coastal processes, will it will support the management of operations at sea in an efficient and safe manner and will complete the functionalities of the marine warning system in the event of an oil spill. The radar system collects and provides data for continuous real-time monitoring of key hydrometeorological parameters ensuring the safety of ships in ports, roadways and approaches to ports. The measurement of surface sea currents and turbulence, combined with AIS, meteorological and video data, integrated to radar stations provide information on the movement of vessels at any time of the day and in all weather conditions, 24/7. It is planned that HF systems will be delivered and installed on sites built on territory owned by DPPI, and the project includes the following activities: Activity 1: Supply and installation of high-frequency radar systems for monitoring the sea surface Activity 2: Construction supervision Activity 3: Information and communication activities Activity 4: Technical assistance and project management 13.03.2025 was accepted as the starting date of the project - the preliminary date of the publication of the public order for the selection of a contractor with the subject "Supply and installation of high-frequency radar systems for the needs of BPI Co".
