Summary
Investigation of a gas release on the MC 280 A platform following an apparent pressure safety valve malfunction and braided steel hose rupture. Venting persisted after shutdown and isolation. Personnel mustered, and subsequent closure of the well production casing valve stopped the release. No injuries were reported.
