It might be said that much current practice in the design of pipe systems to cope with inevitable fluid transients is characterised by its perceived inadequacies, eg: Fluid transient effects are often considered too late in the design process for the best surge alleviation/protection strategies to be adopted. Fluid transient analysts and consultants appear to be risk averse and could be accused of over-specifying surge protection equipment without regard to cost. Unexpected incidents due to fluid transients occur even in pipe systems which appear to have been carefully designed. It is suggested that a risk management approach at the early design stage focussed specifically on the impacts of unsteady flow operations on pipe systems can help to resolve these issues. Normal approaches to surge analysis and protection can easily be fitted into the standard stages of risk identification, analysis, mitigation and monitoring, with particular emphasis being placed on the identification of hazards and the risk levels at which they might be accepted for cost-effective design. Using a risk mitigation framework also helps to suggest appropriate strategies for surge protection. To support the suggested approach, judgements are presented on the contexts in which fluid transient-related risks may be high, possible critical hazard events, issues in modelling fluid transients (and model sensitivity to data), and the categorisation and prioritisation of surge alleviation approaches. © BHR Group 2008.
