Opis:: 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.

Opis:: The aim of this article is to identify and discuss some issues of the safety systems’ design for nuclear power plants equipped with the light water reactors using a defence in depth (D-in-D) conception. Because the functional safety solutions play nowadays an important role for the risk control, the basic requirements for the instrumentation and control systems are specified with regard to relevant international standards. For the design purposes the safety functions are categorized into three categories. The I&C systems implementing these functions are assigned to one of three classes that conform to defined design, manufacturing and qualification requirements. These systems are designed to implement functions of relevant categories. Additional design requirements are discussed, including hardware and software aspects, to achieve and maintain the required reliability commensurate with the importance of the safety functions to be performed to reduce risk.

Opis:: In the article the ProSIL software for computer aided functional safety management is presented. The software consists of three modules for the determination of the required SIL level (ProSILen) and verification of the SIL level (ProSILver). In the ProSIL the calibrated knowledge-based risk graph method for determining the required safety integrity level (SIL) of the safety functions identified in hazard analysis is implemented. The SILs are then verified for safety-related control and protection systems implementing relevant functions with regard to random failures and potential systematic failures. The assessment methods are compatible with international standards IEC 61508 and IEC 61511. Some current challenges and methodological issues concerning knowledge-based functional safety management in life cycle are also discussed.

Opis:: The aim of this article is to identify and discuss some problems that have been encountered in designing and operating the functional safety solutions of higher safety integrity levels (SIL 3 and SIL 4) in the light of analyses outlined in a new version of the international standard IEC 61508:2010. Examples of such solutions are the electric / electronic / programmable electronic systems (E/E/PESs) and the safety instrumented systems (SISs) being designed and operated respectively according to IEC 61508 and IEC 61511 in the system safety life cycle. The role of functional safety solutions is effective reducing and controlling the individual and/or societal risk with regard to tolerable levels defined. Some aspects of potential influence of danger failures of the E/E/PESs or SISs on the plant safety are considered. The influence of common cause failures (CCFs) and dependent failures in the context of the layer of protection analysis is also discussed.

Opis:: The aim of this article is to identify and discuss some issues related to functional safety and security management in hazardous industrial plants. The safety functions are to be realised using the electric / electronic / programmable electronic systems (E/E/PESs) or the safety instrumented systems (SISs) that are designed and operated respectively according to IEC 61508 and IEC 61511 requirements in life cycle. Although the role of functional safety solutions in effective reducing and controlling the individual and/or societal risks has been widely recognised, the substantial problems emerge when E/E/PEs or SISs operate in industrial distributed computer networks. Thus, the security-related problems appear that can introduce some additional risks. An integrated systemic functional safety and security concept is proposed, which includes general requirements as well as appropriate using specified methods and international standards.

Opis:: A security level of distributed control and protection system may have a significant impact on the results of functional safety analysis. However, the issue of integrating the safety and security aspects is difficult and usually is neglected during the functional safety analysis. This article presents a method of functional safety analysis which takes into consideration a concept of integrating these two aspects. It is based on proposed classification of communication channels used in the computer system / network and the scope of such system distribution. The functional safety analysis is to be performed at every stage of system lifecycle, but one of the most important parts is defining required safety functions and determining the safety integrity level for them. The integration concept might be taken into account at this stage. The basis of a method proposed is the assumption that the security level is considered as a risk parameter in graphs of functional safety analyses.

Opis:: This report addresses selected methodological aspects of proactive reliability, functional safety and cyber security management in life cycle of industrial automation and control systems (IACS) in hazardous plants and oil port critical installations based on the analysis of relevant hazards / threats and evaluation of related risks. In addition the insurance company point of view has been also considered, because nowadays the insurer, interested in decreasing risks to be insured, offers the expertise how to limit effectively risks in life cycle from the design conceptual stage of hazardous plant, through its reliable and safe operation, until decommissioning. Therefore, the risk evaluation model for insurance related decision making for the period considered, e.g. one year, should be plant specific with some predictive properties due to changing environment and business conditions, and usually considerable uncertainty involved. The objective is to evaluate and mitigate risks, and control them proactively, through undertaking appropriate activities within a process based management system according to elaborated policy and strategy that includes organisational and technical aspects, including preventive maintenance activities of sensitive equipment and updating in time the training programmes. Careful evaluating and controlling risks is also crucial for the insurance company. Basic activities of the risk engineers and underwriters in the insurance process are outlined in the context of identified hazards/threats and defined factors that significantly influence risks to be considered in evaluating the insurance premium in the context of terms and conditions specified.
