A “well control” incident on the West Hercules rig is being investigated by Norway’s offshore safety watchdog.
The incident took place while the Seadrill-owned rig was drilling an exploration well for Equinor in the Barents Sea.
The lower marine riser package on the blowout preventer was unintentionally disconnected and the work therefore had to be halted, according to Petroleum Safety Authority Norway (PSA).
No personal injuries or leaks were reported as a result of the incident.
The cause is still unknown.
The police were informed.
