Current Federal safety code “General Explosion Protection Rules for Explosive and Fire Hazardous Chemical, Petrochemical Plants and Oil Refineries” differentiates between emergency shut-down (ESD) systems design for oil and gas sector and for chemical, petrochemical plants and refineries. When preparing design documentation for booster pump stations, water pre-separators, oil or gas treatment plants and tank farms, hazard and operability analysis, and safety integrity assessment are performed using semi-quantitative risk analysis. When designing ESD system for oil and gas production facilities safety loops are verified, and requirements for system components are specified. For verification of safety loops, Giprovostokneft JSC provides simulation and calculation of instrumental protection loop reliability using Arbitr program for structural and logical modeling. To select optimal ESD system for hazardous industrial facility, and to provide the required reliability, several safety loop options shall be designed that will use different Manufacturer’s equipment (e.g. gauges, programmed logic controllers having documented reliability indicators). Application of risk analysis methods can validate sufficiency of instrumental protection loops for prompt detection, warning and prevention of hazardous events, and reduce CAPEX, if Russian equivalents of ESD equipment are used in the framework of import substantiation.
