Abstract:
Risk
based inspection is one of the new techniques for inspection planning in oil
and gas industry, it is considered as one of the methods for implementing asset
integrity management, RBI is based on generic data of several accidents and
incidents, which I facilitated the integration of risk management techniques
with the inspection planning and decision making regarding different types and
components of assets in the oil and gas industry. Inspection planning was
depending only on experience and personnel decisions, which used to plan
inspection for equipment only on the basis of shut down for maintenance, or
severe conditions expected based on simple analysis based on their experience.
The contribution of risk management techniques in this field facilitated the
organization of the several factors which could affect inspection planning, and
made several procedures, so inspection planning lead at the end to
cost-effective and safe operation of the equipment. This thesis aimed at
studying the inspection planning for pressure vessels in process plants based
on risk management using the RBI technique, the RBI API standard procedure is
used for the estimation of the final inspection plan of pressure vessels in
process plants. The work was done mainly based on the identification of the
stages required for inspection plan based on the API procedures including data
gathering, inspection readings analysis, corrosion damage mechanisms
identification, probability of failure estimation, consequence of failure
assessment, risk analysis, and finally building the inspection plan for
pressure vessel by implementing the appropriate intervals for safe and
cost-effective operation with the appropriate inspection techniques for the
expected damage mechanisms.
