This article addresses selected technical and organization aspects of risk mitigation in the oil port installations with regard to functional safety requirements specified in standards IEC 61508 and IEC 61511. The procedure for functional safety management includes the hazard identification, risk analysis and assessment, specification of overall safety requirements and definition of safety functions. Based on risk assessment results the safety integrity level (SIL) is determined for consecutive safety functions. These functions are implemented within industrial control system (ICS) that consists of the basic process control system (BPCS) and/or safety instrumented system (SIS). Determination of required SIL related to required risk mitigation is based on semi-quantitative evaluation method. Verification of SIL for considered architectures of BPCS and/or SIS is supported by probabilistic models with appropriate data and model parameters including security-related aspects. The approach proposed is illustrated on example of oil port installations. In final part of the article the insurance aspects are discussed in managing risks, as some risks are to be transferred to an insurance company.
