The Norwegian Coastal Administration administers a system of navigation guidance devices in Norway. This system comprises devices run by the Norwegian Coastal Administration, devices run by municipal ports and private devices run by others. Navigation guidance devices provide visual and electronic signals that are designed to assist with the navigation process for cautious seafarers. However, the purpose is not to make it possible for seafarers to identify every underwater rock or shallows or obstacles for shipping in Norwegian waters that can otherwise be navigated by ships. On the other hand, the Norwegian Coastal Administration must ensure that the waters are marked reasonably, to the extent permitted by resources.
