The LOPA method is a half quantitative methods that can meet this requirement. Choice and proper application of the LOPA method to determine the SIL (Safety Inetgrity Level) required, based on the enormous challenges of process safety. The key process is bound to the proper consideration of the probabilities of occurrence of the identified scenarios and risk reduction factors associated with security functions provided by the protective layers. In this work, we evaluate them by the fault tree (AdD). The principle of the LOPA method is to first identify the major scenarios of an installation and to assess the consequences of these scenarios. Depending on the severity of the consequences, the next step is to identify the different protection layers provided to deal with these scenarios to assess the safety barriers performance and specifically the SIS by the SIL calculation.
