Updating Norwegian Sector Lights to Fit IALA Standards

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).

IALA has made a recommendation on how the sectors of a sector light should be organized in order to be intuitive and predictable (IALA Guideline 1041: Sector Lights, 3rd ed.). The Norwegian Coastal Administration has decided to apply to this recommendation and will begin changing the sectors in Norwegian waters during 2019. Work has already begun, but the scope of the activity will increase. The work is expected to be finished by the end of 2025.

The principle for the IALA recommendation is that when mariners approach a sector light in a white sector, the sector to starboard shall be green, and the sector to port shall be red. This principle applies whatever direction the mariner is approaching from.

The usefulness of this measure has been thoroughly analysed. Cost-benefit analyses have shown that the measure is necessary.

The work will be incorporated into the planned changes and maintenance work that is already necessary, and will, therefore, be carried out periodically. This means that the changes will take place in accordance with our plans for inspection and maintenance.
During the transition to IALA standards, some navigational aids will be relocated, removed, or modernized to improve maritime safety.

Mariners will require less time to study nautical charts while sailing at night. It will, however, remain important that mariners plan their voyages well and that they use updated nautical charts when doing so.
