Summary
Investigation of a cracker-naphtha leak at Mongstad attributes the release to internal corrosion in a pump protection line. It examines deposition, flow regulation and risk-based inspection shortcomings, alongside inadequately assessed operating changes, inconsistent procedures and deficient clear-up work permits. The report also considers chemical exposure and evacuation-alarm performance.
