Summary
Explains how operational trade-offs can gradually erode safety margins, using a well abandonment campaign involving offshore hydrocarbon gas venting. Examines deficient hazard assessment, equipment assurance and modification controls through systems theory, distinguishing possible explanations from verified findings. Introduces guided adaptability to support anticipation, coordinated responses and proactive learning.
