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.

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.

Offshore vessels at the facilities

Within 2 km of a facility and under 1 knot. AIS from Kystverket (Norwegian Coastal Administration, Kystdatahuset real-time picture) (NLOD 1.0), 7 Oct 2026, 14:34 UTC · Norwegian Coastal Administration, Kystdatahuset: reported voyages and register type (SafeSeaNet) (NLOD 1.0), 6 Oct 2026

Visits, latest day with data: 1 Oct

Rigs and offshore vessels that lay within 2 km of a facility at under 1 knot for at least 30 minutes, according to the AIS positions for 1 Oct 2026 from the Norwegian Coastal Administration. Kystdatahuset publishes the history about a week late. A visit shows that the vessel was there, not who it worked for. AIS from Kystverket (Norwegian Coastal Administration, Kystdatahuset historical positions) (NLOD 1.0), latest day 1 Oct 2026 · Norwegian Coastal Administration, Kystdatahuset: register type (SafeSeaNet) (NLOD 1.0), 1 Oct 2026 · Norwegian Offshore Directorate, facilities with position (NLOD 2.0), 7 Oct 2026 · OESA, rig key Sodir ↔ MMSI ↔ IMO (curated) (NLOD 1.0 / NLOD 2.0), 7 Oct 2026

No rigs or offshore vessels lay at the facilities in the period.

Method: A visit is a continuous stay within 2 km of a facility at under 1 knot for at least 30 minutes, computed from the AIS positions. Gaps in the data of up to 60 minutes, or 3 hours when the vessel is in the same place before and after, do not count as interruptions. Hours are the sum of the visits. Only rigs and vessels with an offshore register type or registered with the Norwegian Offshore Directorate are included.

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. AIS coverage offshore varies. A vessel without positions for a period may have been there without being recorded. 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.

Last 12 months (7 Oct 2025–7 Oct 2026). Wells: exploration wells (wildcat and appraisal). Development wells appear under Rigs when a rig moves there. 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.
