The Hydrographic Institute of the Republic of Croatia (HHI) participated online in the 33rd meeting of the PRIMAR Advisory Committee (PAC33), held from 3 to 5 November 2026 in Tirana, Albania. Representatives of 12 PRIMAR member countries attended the meeting, both in person and online.

The meeting reviewed PRIMAR's business performance, strategic and financial priorities for 2027, and activities related to the implementation of the S-100 framework, which forms the foundation for the next generation of official digital navigational products and services.

Particular attention was given to the development of distribution infrastructure, interoperability of S-100 products, and strengthening the capacities of national Hydrographic Offices for their production and implementation. The introduction of S-100 will enable the use of more detailed, up-to-date and interconnected official maritime data, contributing to navigational safety, more efficient maritime traffic management and marine environmental protection.

At HHI's initiative, the distribution of official digital nautical publications was included among PRIMAR's further development activities, with the Croatian publication Sailing Directions Adriatic Pilot – Croatian Coast serving as a pilot case.

The meeting also confirmed that HHI will host the next PRIMAR Advisory Committee meeting (PAC34), scheduled to take place in Dubrovnik in November 2027.

Through its participation in PRIMAR, HHI continues to actively contribute to international cooperation in hydrography, the development and implementation of the S-100 framework, and ensuring the availability of official hydrographic data and navigational products. These activities are of particular importance for the further development of Croatia's national hydrographic services and the enhancement of navigational safety in Croatian waters.
