Barrier Change Analysis Method
“Change is the mother of twins — progress and trouble” . In some areas of operation, change is the very mechanism for survival. In the exploitation of non-renewable resources, like oil and gas, the operations and maintenance costs will at some point exceed the revenues. In order to maximize the overall exploitation of the reservoir, the cost side has to be reduced and the key word is“change” — technical, operational, and organizational changes. In particular remote operation and de-manning are relevant measures to extend the tail production phase. Another topical issue is major replacements of old equipment, e. g., the safety and automation system, due to lack of spare parts and problems in maintaining sufficient competence on yesterday’s systems. The central issue then, from a safety perspective, is how to analyze such complex changes with respect to their effect on the risk of accidents (the“trouble” part of change).
