Managing actual or perceived risk in today’s environment is the concern of every industry and government. For oil and gas pipelines, prevention of mechanical interference by excavation equipment is one of the most effective ways to reduce incidents and to manage operating risk. A common technique used to manage reliability, risk and safety is the fault tree method. In general terms, a fault tree model identifies important events and combinations of events, with respect to system reliability, to estimate the likelihood of system failures. When applied to damage prevention, the fault tree forms a logical representation of the manner in which the combined fault effects associated with individual prevention measures could lead to a hypothesized failure of an operator’s damage prevention program. The model presented in this paper considers performance factors such as signage, patrols, one-call practices, excavation techniques, public awareness programs and new damage prevention technologies.
