Here you will find commonly asked questions and answers to the ongoing work on sector lights. If you have other questions, please see "Contact information".
The International Association of Lighthouse Authorities (IALA) is an intergovernmental organization founded in 1957 to collect and provide nautical expertise between members. IALA facilitates the member states to work together to achieve the most harmonized maritime system worldwide. Norway, represented by the Norwegian Coastal Administration, is an important member who contributes actively to this cooperation.
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. 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 illustration below shows how the sector classification will be changed by the transition to the IALA standard. The map on the left-hand side shows before, while the map on the right-hand side shows sectors after the transition. Drag the vertical bar back and forth to see the changes.
The Norwegian Coastal Administration has chosen to adhere to IALA’s recommendations. The decision was made by the NCA itself.
Yes, the usefulness of this measure has been thoroughly analyzed. Cost-benefit analyses have shown that the measure is necessary.
The work has already begun, but the scope of the activity will increase. The work is planned to be completed by the end of 2025.
he change will improve predictability for mariners, as we will follow the same principles that have been recommended by IALA.
Mariners will require less time to study navigation charts during night-time voyages. Please note, however, that it will remain important to plan your voyage well and of course to use updated nautical charts when doing so.

The work in changing the sector lights will be carried out during all hours of the day throughout the year, but the sector lights will only be visible when it is dark.
Some navigational aids will be replaced and upgraded. These will differ from the current design.

No, the sector lights will be the same regardless of location or what types or sizes of vessels will be using them. However, in some locations, the Norwegian Coastal Administration has established fairways especially for recreational crafts.
No, but some navigational aids will be moved, removed or modernized to make the service more straightforward and intuitive for mariners. This will facilitate the safety of navigation. However, remember to have up-to-date maps!
The rules will not change, but implementing the IALA standard on sector lights, will provide better predictability when using the sector lights at nighttime.
No, this is a part of the Norwegian Coastal Administration’s tasks and responsibilities. Updating your own nautical charts may however incur an expense.
No, but textbooks and education will include the principle of IALA standards for sector light navigation.
A basis for maritime travel is that everyone ensures that they update their nautical charts. The Coastal Administration also has a service that shows upcoming changes and changes that are about to be made to nautical charts.

The Norwegian Coastal Administration will disseminate information about this transition, both to various Norwegian boating magazines and local newspapers and at fairs. Over time, textbooks and classes will include the principle underlying the IALA standard for sector lights.
No, the work will only result in changes to sector lights.
No, but mariners must ensure to update charts on board.
No, you don't risk stricter penalties. Each individual must, however, be diligent in updating their nautical charts and planning their voyage thoroughly. The Norwegian Coastal Administration will not be liable to pay damages in the event of misinterpretation.
Information about the NCA’s transition to the IALA standard for sector lights can primarily be found on these pages. In addition, boating magazines, newspapers, and other media will write about the ongoing transition.
The NCA also has a nautical chart service that shows changes that are upcoming as well as changes that are about to be made to nautical charts. You can find this service here (Norwegian text only).

The EFS information service (Etterretning for sjøfarende, or “Information for Seafarers”) will publish our changes on an ongoing basis, as these changes are carried out.
