Transition to IALA Standard

In the period 2019 to 2025, the Norwegian Coastal Administration will be reorganizing the sectors of around 1900 sector lights in compliance with the standard defined by IALA (International Association of Lighthouse Authorities).

The Oslofjord fairway project that was completed in 2017, is an example of how sectors will be organized in accordance with the new standard.
