RBI is an optimum inspection strategy that is commonly used to identify high risk equipment such as pressure vessels, tanks, heat exchangers, piping and associated equipment. The high-risk equipment items are likely to be exposed to different types of degradation such as corrosion, fatigue and mechanical damage and could lead to catastrophic failures in the plant.

Why use Risk Based Inspection?
For asset intensive industries, such as oil & gas as well as energy sectors, risk-based inspection (RBI) is an increasingly recognized approach adopted by various plant owners to prioritize the resources based on the associated risks calculation. Based on the RBI results, the plant owners will be more aware of the risk level of their assets and are able to allocate their resources effectively.

A corrosion review is a qualitative risk assessment process that can be used per API-RP 580, “Risk-based Inspection”, to set appropriate risk-based inspection intervals.

It is used primarily in three ways:

1. To prepare the proposed worklist for an optimized inspection plan or to review execution of an upcoming turnaround using sound engineering risk assessment. For this use, the corrosion review focuses on establishing the likelihood of failure and a proposed mitigation strategy. The turnaround process is used to establish a consequence, which is then used to complete the risk assessment and relative risk ranking.
2. To do the full qualitative risk assessment by establishing the consequence of failure, and the associated risk level. This approach is used primarily for work completed outside of turnarounds and setting optimised inspection plans.
3. To use a risk-based approach for setting inspection intervals for equipment types not covered by an existing RBI methodology (Asset specific or API 580 RBI Methodology).

RBI review services from Anti Corrosion Technology provides that optimizes inspection efforts based on risk. Risk, in this context, is determined by the likelihood of a failure or breach of containment due to damage mechanisms and the consequences of it impacting on safety, environment and economics.

Inspection strategies can then be developed based on the results of RBI, with more focus on high-risk equipment. Plant availability and safety has significantly improved using this approach, whilst achieving greatly reduced unplanned shutdowns and costs as a favourable by product.

Our experienced RBI team brings you the perfect compromise to balance inspection costs and risk reduction with a personalised approach based on a proven method. Our experts have vast knowledge of materials and damage mechanisms, industry specific operational background to assess the risks of the assets in an accurate and reliable manner.

• Study the probability and consequence of failure for RBI assessment
• Comply with all applicable regulations and guidelines
• Identify risks associated with equipment degradation and corrosion rates using industry standards, such as API-580, API-579, and API-581
• Validate mechanical integrity and reliability of your equipment
• Optimize the work of your inspection and maintenance teams by focusing on the equipment and systems with the highest risks
• Extending the service life of statutory equipment and assets

The reviews are about performing the right amount of inspection work and the right amount of maintenance work at the right time to obtain the appropriate amount of risk level acceptable to the site and meet corporate HS&E requirements.

Anti Corrosion Technology team consists of professionals with more than 100 years combined expertise in providing trusted risk-based inspection assessment for your facility. Facility equipment using asset specific RBI methodology is not focused solely at cutting pressure equipment workscope or inspection execution.
