What happened

Beginning around 28 September 2022, Norway's Petroleum Safety Authority (PSA) said operators including Equinor had reported a spike in observations of unidentified drones near offshore installations, starting with sightings reported near the Johan Sverdrup and Heidrun platforms; the PSA urged operators and vessel owners to show increased vigilance and report observations, while explicitly declining to speculate about causes. Sightings subsequently spread to numerous other platforms including Sleipner, roughly 250 km from shore, and to onshore gas facilities including the Kårstø gas-processing terminal and the Nyhamna gas plant that processes Ormen Lange field gas feeding UK supply, according to Norwegian media and Reuters-sourced reporting; more than 70 offshore workers were reported to have described drone sightings to industry safety representatives. Norway's government responded by deploying warships, coastguard vessels and fighter jets to patrol offshore facilities, stationing soldiers at onshore refineries and gas plants, and briefly closing Bergen's Flesland airport due to a drone sighting; the Police Security Service (PST) took over the investigation from local police on 19 October, and Prime Minister Jonas Gahr Støre said allied navies from France, Germany and the UK had been invited to assist with surveillance. Norwegian police detained at least seven Russian nationals in October in connection with carrying or illegally flying drones, including 50-year-old Vitaly Rustanov, arrested at the Storskog border crossing with two drones and an encrypted 4-terabyte data cache; Rustanov denied wrongdoing and said he had flown drones as a tourist for personal reasons. None of the reviewed reporting establishes that any detained individual's activity was linked to a specific platform sighting or that the wider wave constituted a coordinated state operation; the PST's investigation had not published a conclusive attribution in the material reviewed. Russia's embassy in Oslo rejected suggestions of Russian government involvement. No source reviewed reported production shutdowns, physical damage or a confirmed security breach at any installation resulting from the sightings; the response is documented here as a large, officially confirmed security episode with disputed attribution, not as a confirmed sabotage or espionage operation. The marker is placed at a representative North Sea location (near the Johan Sverdrup field) and does not represent any single platform or an exact sighting position.
