The cornerstone of plant integrity is ensuring that facilities are correctly designed, and operated and maintained within the equipment design envelopes. The profitability of the facilities is significantly impacted by the cost-effectiveness of inspection and maintenance strategies and programs in place. Plant equipment is subjected to deterioration mechanisms and potential damage throughout their service life. To know with confidence the current condition of plant equipment, we need to inspect the equipment. Moreover, to determine the next inspection date, we need to understand the deterioration mechanisms to which the equipment will be exposed and their effects. This entails identifying the deterioration mechanisms; determining their rates; acceptability criteria; and the extent, frequency, and methods for inspecting this equipment.
Traditionally, prescriptive inspection practices were developed based on experience and in some cases in response to significant failure cases. In general, they did not take full account of failure risks nor of the degradation mechanisms that the equipment is exposed to in operation. As a result, some companies would not do enough inspection and precipitate avoidable failures, while others would unnecessarily overspend, resulting in significant waste of resource.
Risk Based methodologies enable the assessment of the likelihood and potential consequences of equipment failures. RBI & RCM provide companies the opportunity to prioritize their equipment for inspection; optimize inspection methods, frequencies and resources and develop specific equipment inspection plans. This results in improved safety, lower failure risk, fewer forced shutdowns, and reduced operational costs.
The risk-based approach requires a systematic, and integrated use of expertise from the different disciplines that impact plant integrity. These include design, materials selection, operating parameters and scenarios, and understanding of the current and future degradation mechanisms and of the risks involved.
