ظروف تحت‌فشار ، مخازن ذخيره ، سيستم‌هاي لوله‌كشي و ساير تجهيزات صنايع علي‌الخصوص صنايع نفت، گاز و پتروشيمي باگذشت زمان در معرض انواع گوناگوني از تخريب‌ها قرارگرفته و مستهلك مي‌شوند. به‌منظور جلوگيري از وقوع حوادث ناگوار و به حداقل رسانيدن خطرات غيرمنتظره، بازرسي تجهيزات ازلحاظ وجود يكپارچگي مكانيكي و سرويس‌دهي ايمن و مداوم تأسيسات امري حساس هست. باگذشت زمان و با افزايش عمر يك واحد؛ الزامات نگهداري اهميت مي‌يابد. به‌منظور بهبود ايمني و دستيابي به سازگاري بهينه، سرمايه‌گذاري در نگهداري الزامي است. فنّاوري بازرسي بر مبناي ريسك به شركت ها اين توانايي را مي‌دهد تا محدوده اي از فاكتورهاي كليدي نظير: در نظر گرفتن سطح قابليت اعتماد به تجهيزات ايمني، محيط زيست، مسائل مالي را در فرآيندهاي تصميم گيري خود مد نظر داشته باشند. هدف اصلي از طبقه بندي تجهيزات براساس ريسك آن‌ها، ايجاد پايه اي براي بازرسي اين تجهيزات با توجه به ريسك آن‌ها هست كه در آن منابع مورد نياز زمان و هزينه براي برنامه بازرسي بهينه سازي شده باشد.

Identification and Prioritization of Risks Related to Risk Basic Inspection Using Fuzzy Topsis Method in Gas Refinery for the Thesis for a master's degree in engineering management

Pressure vessels, storage tanks, piping systems and other industrial equipment, especially the oil, gas and petrochemical industries, are exposed to various types of degradation and wear over time. In order to prevent accidents and minimize unexpected hazards, equipment inspection is critical for mechanical integrity and safe and continuous service of facilities. Over time, as the life of a unit increases; Maintenance requirements are important. In order to improve safety and achieve optimal compatibility, investment in maintenance is required. Extreme levels of inspection are evident. An unfavorable inspection process is the implementation of the least possible inspection along with the replacement of equipment in the event of an equipment leak or failure. During such inspections, due to the risks to life, environment and financial costs that follow. Has it; It is clear that this method is unacceptable. On the other hand, with the process of repeated inspections and the number of frequent visits, inspection costs increase significantly. The first and, in fact, the most natural method of maintenance has been corrective repairs. This method is based on the principle "Whenever it breaks, repair it". This old method of maintenance, which is still used for insensitive and critical components, only pays attention to when a part is broken or damaged. This method, especially for sensitive devices and components, was replaced by the concept of scheduled maintenance, in which it was assumed that all issues related to the design and maintenance of sensitive components such as pressurized components or aircraft engine components could be predicted. By removing them, the desired level of safety was achieved.
