The LOPA (layer of protection analysis) of IEC 61511 was applied to determination of the safety integrity level of the safety systems for a cryogenic pump test facility as a large-scale mechanical system. The whole system was divided into seven segments, and the severity of each accident was evaluated considering the potential hazards suggested by API RP 14C. The LOPA was applied to the accidents with the severity level of C, D, E and F. An accident had multiple hazards, and its frequency was compared to the acceptable frequency with the failure frequency of the independent protection layers taken into account. Accidents required safety systems with SIL 1 or stricter necessitated safety-instrumented systems. If the required safety integrity level was SIL 3 or stricter, detailed and quantitative risk analysis was requested to justify the assigned safety integrity level.
