Summary
HSE alerts operators to a spring-return pipeline emergency shutdown valve that failed open, disabling platform isolation. Initial indications linked retaining-rod failure to corrosion; released springs and an end plate presented stored-energy hazards. It calls for prompt inspection, conditional temporary restraints, actuator performance testing, coating and seal maintenance, and review of corrosion-resistant designs.
