- Uncontrolled release of a flammable gas or liquid
Specific Incident Equipment
Flow wing actuator
Investigation confirmed that the seal failure was down to fair wear and tear. These actuators are tested annually by Well Services and during the last test no leak was identified. The tell tale operated as per design and prevented overpressure of the actuator canister.
The Well was immediately isolated.
Actuator was replaced.
