The approach addresses selected technical and organization aspects of risk mitigation in the oil port installations with regard to functional safety and security requirements specified in standards IEC 61508, IEC 61511 and IEC 62443. 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 the risk evaluation results the safety integrity level (SIL) and security assurance level (SAL) will be determined for consecutive safety functions. The proposed approach will be composed of the following items: process and procedure based safety and security management, example of procedure based safety management including insurance, integrated safety and security assessment of industrial control system (ICS) of the oil port pipelines, tanks and critical infrastructure.
