Design Risk Based Inspection software, prioritized inspection schedule of Gas City Gate Station

چکیده مقاله

In today’s world, optimization of energy, resources and cost are concerned in industry. Operational costs, maintenance and repairs, risks and consequences caused by devices destruction impose huge costs to companies. Development of management theory, which is based on risk components in gas and oil industries, has provided required platform to promote and develop new strategies for equipments inspection and maintenance. RBI is the new risk-based approach for industrial equipments prioritization, which leads to risk management, increased safety, production continuity and inspection costs reduction. In this approach, risk is classified based on two independent factor of occurrence probability and occurrence consequence. Risk-based inspection can be implemented in qualitative, quantitative and semi-quantitative methods. In an operational unit, a high percentage of risk is related to small number of devices, thus resources can be focused on equipments with higher risk using a proper planning. In this regard, a software was designed based on API581 standard and risk matrix of gas pressure reduction station was obtained based on qualitative risk-based inspection for inspection intervals prioritization.
