Abstract

Risk-informed categorisation is based on utilising PSA information in a consistent way to select most cost-effective methods to control risk associated with systems, structures and components. In the presented method, an item's risk significance is broken in two parts: probability of failure and the consequence of failure. Higher value in either will possibly mean a higher risk category, depending on the limit values for each category. Risk categorisation aims at identification of items for improved reliability or added redundancy, versus the mostly reliability enhancing measures in safety classification.
