The Petroleum Safety Authority Norway (PSA) said it is investigating a well control incident which occurred last week on Seadrill’s semi-submersible rig West Hercules.
The rig is currently operating for Equinor in the Barents Sea, and on January 16 during drilling operations the lower marine riser package on the blowout preventer was unintentionally disconnected. Work had to be halted as a result, although no injuries of environmental discharges were reported as a result of the incident.
The cause of the incident is unknown, however PSA has informed police and will support them with technical support if needed.
PSA will also conduct its own investigations, which will published once concluded.
