The network

From owner to market. Links without their own label have their source in the column heading; curated, derived and possible links are labelled at the link.

  • The colour shows the content:
  • Gas
  • Oil
  • Condensate
  • CO₂
  • Oil and condensate
  • The line shows the source:
  • pipeline in Sodir data
  • curated from Sodir's field description
  • possible onward route, not measured flow
  • planned or not in service

The links show direction, not volume.

Notes

Fleet

Rigs drilling, offshore vessels at the facilities in the AIS picture 7 Oct 2026, 14:34 UTC and the supply vessels from the base in the last 30 days.

Supply vessels from the base, last 30 days

Reported departures by offshore vessels (register type in SafeSeaNet). Supply base: Norwegian Offshore Directorate (the field's main supply base); the port's position from the World Port Index, Wikidata or OpenStreetMap (NLOD 2.0 / offentlig eiendom / ODbL), 28 Sep 2026 · Norwegian Coastal Administration, Kystdatahuset: reported voyages and register type (SafeSeaNet) (NLOD 1.0), 6 Oct 2026

Who charters a rig or vessel, and at what rate, is not in open data. A vessel is linked to a field only when AIS shows it within 2 km of one of the field's own facilities or its host facility, at under 1 knot – that says the vessel was there, not who it works for. Facilities on the export route do not count. Tankers loading oil from production ships (FPSOs) and loading buoys are not included. Supply vessels per base are based on reported departures (SafeSeaNet). The destination is usually just the sea area (“Offshoreinst. Nordsjøen”, “… Barentshavet”), so the field the vessel supplies is not stated. Peterhead is British and has no departures in Kystdatahuset. Ship data: Norwegian Coastal Administration. Not for navigation.

Events

Ownership changes, exploration wells and discoveries, rigs that move, production start-up and contracts, with a link to the source.

No events in the last 12 months in the data.

Last 12 months (7 Oct 2025–7 Oct 2026). Sources: Norwegian Offshore Directorate (Sodir, NLOD 2.0): licence transfers (retrieved 7 Oct 2026), exploration wells and discoveries (7 Oct 2026), wellbores with drilling rig and the company responsible for the rig (7 Oct 2026) and field status (7 Oct 2026).

Sources

All figures and links on the page come from these sources. Curated links are entered by hand by OESA from the source text, and the quote is checked against the source at every build.

Not in the data: Flow in each pipeline, which field's gas ends up in which country, and the buyers of oil and gas. Gas is mixed in the network, so a “possible route” is a pipeline connection, not measured flow.
