Summary
Investigation of a hydrocarbon leak on Ula P attributes valve bolt fracture to chloride stress corrosion following exposure to produced water. It examines inconsistent material certification, assessment of earlier seepage, shutdown failures, ignition isolation and fire protection. Emergency planning and clean-up assessments also showed deficiencies; no people were injured.
