Offshore infrastructure across the North Sea and Norwegian Sea
A map of the whole basin rather than one country: the fields, pipelines, platforms, wells and licence blocks of the Norwegian, British, Dutch and Danish continental shelves, drawn together over seabed relief, with the offshore wind farms and the subsea power and telecom cables that cross between them.
Why this map carries fewer layers than the Norwegian one
Every layer here exists for every country on it. Norway publishes things its neighbours do not, including per-field emissions to air, a harmonised stratigraphy, wellbore deviation surveys and a live AIS feed. Those layers stay on the Norwegian map, because a layer that lights up over one country and leaves three blank teaches a reader something false about the other three. A blank area on this map means nothing is there, not that the data is missing.
Where the data comes from
Norwegian data is from the Norwegian Offshore Directorate, British data from the North Sea Transition Authority under the Open Government Licence, Dutch data from NLOG, run by TNO, and Danish data from the Danish Energy Agency. Wind farms and cables come from EMODnet Human Activities and OpenStreetMap. Seabed relief is derived from global elevation tiles. Basemap tiles are © OpenStreetMap contributors and © CARTO.
What is estimated rather than measured
Production is annual totals converted to barrels of oil equivalent using standard factors, so a figure here will differ slightly from one quoted in tonnes or cubic metres. Some cable routes are schematic, drawn between their landing points rather than surveyed. Nothing on this map is for navigation or operational use.
