Summary
Investigation of an arc-flash fire in Perdido’s silicon controlled rectifier cabinet during wireline logging and hydrate-mitigation pumping. Findings identify buss-insulator failure as the probable cause and equipment age as a contributor. The report examines ineffective fire detection and the limitations of external thermal imaging despite up-to-date maintenance.
