Investigation launched after another safety incident on Hibernia platform
An investigation has been launched following a near-miss incident on the Hibernia platform located offshore Canada. This is the fourth such incident on the platform this year.
In an incident bulletin on Friday, Canada’s offshore regulator, Canada-Newfoundland and Labrador Offshore Petroleum Board (C-NLOPB), said the incident happened last Wednesday 5 October 2022.
Hibernia Management and Development Company (HMDC) reported that personnel were in the process of completing a pressure test of the high pressure manifold on the Hibernia platform. Personnel had closed the upper diverter valve when the valve handle and gear box cap (which weighs approximately 27 kg) separated and travelled a distance of 3.9 meters.
No personnel were injured and no equipment was damaged. The location where the incident occurred was barricaded and deemed a restricted area. Five authorized personnel were in the work area at the time of the incident.
HMDC immediately ceased operations in the area and has initiated an investigation to determine the potential classification and root cause of the incident, which the C-NLOPB is monitoring. The Certifying Authority has imposed limitations on related equipment until repairs have been completed and the operator has demonstrated that related systems are fit for use.
C-NLOPB said its Safety Officers were already scheduled to travel to the Hibernia platform in the coming days and will follow up with HMDC to review this incident.

It began producing oil in November 1997, making it Newfoundland and Labrador’s first offshore production platform.
