1   Scope This Technical Report aims to close the gap between the state-of-the-art and the application of probabilistic calculations for the safety systems of the petroleum, petrochemical and natural gas industries. It provides guidelines for reliability and safety system analysts and the oil and gas industries to:

• understand the correct meaning of the definitions used in the reliability field;

• identify

— the safety systems which may be concerned,

— the difficulties encountered when dealing with reliability modelling and calculation of safety systems ,

— the relevant probabilistic parameters to be considered;

• be informed of effective solutions overcoming the encountered difficulties and allowing to undertake the calculations of relevant probabilistic parameters;
