Where the rigs and vessels have been, 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

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. 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.

• Sodir has no position, client or contract for the vessels. The list only shows that the vessel is registered at Sodir with the company as responsible party.
