Summary
Investigation of a platform fire during wireline solvent treatment and chemical flowback into an open-top tank. A consultant suffered burns and personnel evacuated. Findings examine uncontrolled well flow, inadequate grounding, unavailable safety valves and deficient work planning; a forensic assessment attributed ignition to static discharge near the gas buster or tank.
