ST. JOHN’S, Newfoundland and Labrador – Various industry reports indicate that Hibernia Management and Development Co. Ltd. (HMDC), the operator of the Hibernia platform in the Atlantic Ocean off Canada, reported that a near-miss incident occurred on the platform on October 5.
According to HMDC, as reported to safety regulator CNLOPB, rig personnel were completing a pressure test of the high pressure manifold on the Hibernia rig.
Staff had closed the upper bypass valve when the valve handle and gearbox cap (which weighs approximately 27 kg) separated and traveled a distance of 3.9 m.
No personnel were injured and no equipment was damaged. The place where the incident took place has been barricaded and considered a restricted area. At the time of the incident, five authorized persons were in the work area.
HMDC immediately ceased operations in the area and launched an investigation to determine the potential classification and root cause of the incident, which CTLPO is monitoring.
The certification authority has imposed limitations on associated equipment until repairs are completed and the operator has demonstrated that the associated systems are fit for purpose. CNSOPB security officers were already scheduled to visit the Hibernia platform in the coming days and will follow up with HMDC to review this incident.
HMDC shareholders are ExxonMobil Canada (33.125%), Chevron Canada Resources (26.875%), Suncor (20%), Canada Hibernia Holding Corporation (8.5%), Murphy Oil (6.5%) and Equinor Canada Ltd. (5%).
In 2021, HMDC opened an investigation following a crane incident in May on the Hibernia platform complex off Newfoundland and Labrador. According to the Agency, two staff members were attempting to connect a 10ft x 8ft container lifting bridle to a 10m (33ft) flag line at the east pedestal crane’s main hook.
