The reference routes for Navigation are recommendations from the Norwegian Coastal Administration (NCA) to support voyage planning based on our best practice. The routes are not binding and they shall not replace any required navigational aids or navigation duties, including the rules at sea (COLREG) and standards regarding voyage planning and watchkeeping. The routes shall not cause any change in responsibilities for the captain or officer in charge for safe navigation and maneuvrering of his vessel. The main category of reference routes are developed for a maximum ship dimension of 150m LOA and 9m draught or less. Some routes included are for ships of even smaller maximum dimensions due to local limitations. Other cateogries of routes can be included. When using reference routes for route planning please confer relevant regulations and navigational charts for actual maximum vessel dimensions of the specific route. The NCA will keep routes updated regularly. See more about use of the reference routes for navigation in NCA’s service ‘www.Routeinfo.no’.

The dataset shows state speed limits at sea for recreational vessels valid from 01.01.2022. A recreational craft is defined as a vessels that have a maximum length of up to 24 meters, and that are not used in commercial activities. The limitations are given by the Regulations on state speed limits at sea according to the Ports and Waters Act §7.

This map service is part of the maritime traffic regulations. The service shows the traffic separation systems and service areas for the Norwegian Coastal Administration's traffic centers (VTS / Vessel Traffic Services). In addition, entry corridors and business areas specified in the regulations are shown. TSS is also made available through the Norwegian Coastal Administration's WMS / WFS.

Lay-up areas are represented as flats and indicate areas appropriate for longer periods of anchoring/storage for offshore installations.

Fairways are indicated through the Regulation on fairways. The entire coast of Norway is currently covered by a standardised reference system of various fairway categories. The fairway structure includes the network of maritime transport arteries and is a national geographical reference system for measures within administration, planning, development and operational activities in the coastal zone. More about the fairway structure: http://www.kystverket.no/Maritim-infrastruktur/Farleder/Farledsstrukturen/ The dataset shows the extent of the main and secondary fairway in terms of area.

The service includes a description of the Norwegian Coastal Administration's pre-evaluated emergency port locations included in the Norwegian Coastal Administration's emergency response plans. These locations are deemed to be the most relevant locations in which to place ships in distress in order to avoid or limit acute contamination. The data constitutes part of the Norwegian Coastal Administration's decision support tool for use in situations where there is a risk of acute contamination or such contamination has already occurred. In individual situations, any location is a possible emergency port. Emergency port categories: The emergency port locations are divided into three categories. Category 1: Emergency ports that are particularly well-suited to the biggest ships (tankers and large bulk carriers). Category 1 emergency ports will primarily be needed in connection with outer fairways used by tankers, as well as fairways into oil terminals and other ports used by tankers and product tankers. Can also be used by other traffic in the area. Design sizes (metres); Length: 330, Width: 60, Draught: 18 Category 2: Emergency ports for the anticipated traffic in the area. Primarily ships over 5000 BT. Design sizes (metres); Length: 200, Width: 25, Draught: 10.5 Category 3: A third category has been introduced in some Norwegian Coastal Administration regions, with a maximum ship length of 120 metres and a maximum width of 15 metres. The maximum depth is then assessed in each individual case, depending on local conditions, to see whether the ship can approach safely. Design sizes (metres); Length: 120, Width: 15

Fairways are indicated through the Regulation dated 30 November 2009, no. 1477 (Regulation on fairways). The entire coast of Norway is currently covered by a standardised reference system of various fairway categories. The fairway structure includes the network of maritime transport arteries and is a national geographical reference system for measures within administration, planning, development and operational activities in the coastal zone.

Historisk AIS (HAIS) offers downloads of historical ship positions from the Norwegian AIS network, including both base stations and the Norwegian Coastal Administration's low polar orbit satellites. The geographical coverage is limited to the Norwegian economic zone, as well as the fishing zones around Jan Mayen and Spitsbergen. On a ship level, fishing vessels under 15m and recreational vessels under 45m are exempt from public disclosure. The service allows you to select a geographical area for data extraction, a time period, search for individual ships, or filter by ship types. Upon ordering, you will receive a download link for the dataset in (Geo)Parquet format.

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.
