Inspect ALL your equipment with semi-quantitative, fully quantitative and
qualitative methodology to create ONE UNIFIED inspection plan
Using Risk Matrix for ranking the equipment
|
RBI is an integrated methodology that uses risk as a basis for prioritising and managing an in-service equipment inspection program by combining both the likelihood of failure and the consequence of failure.
Utilising the output of the PiMSlider RBI Extension, the user can design an inspection program that manages or maintains the risk of equipment failures.
The PiMSlider RBI Expert module can manage 1000s of units of equipment and any kind or type of equipment can be presented on the PiMSlider® map. Choose from any mapping source, such as Google, Street Maps, Bing and many others.
The following are three major goals of the ATP RBI Expert module:
| Provide the capability to define and quantify the risk of process equipment failure, creating an effective tool for managing many of the important elements of a process plant |
| Allow management to review safety, environmental, and business-interruption risks in an integrated, cost effective manner |
| Systematically reduce the likelihood and consequence of failure by allocating inspection resources to high risk equipment |
|
ATP's PiMSlider 2011 RBI Expert module offer three difference approaches to RBI: |
Qualitative approach | Quantitative approach | Bow-Tie approach |
based on descriptive data using engineering judgment and experience |
based on probabilistic or statistical models |
based on descriptive data using engineering judgment and experience and is effectively a qualitative measure |
By comparison, a qualitative approach requires data input based on descriptive information, using engineering judgment and experience as the basis for the analysis of probability and consequences of failure.
Inputs are typically given in data ranges instead of discrete values. Results are typically given in qualitative terms such as high, medium or low. The value of this type of analysis is that it enables completion of a risk assessment in the absence of detailed quantitative data. It also produces results more quickly.
The accuracy of results from a qualitative analysis is dependent on the background and expertise of the analysts. |
This approach requires a relatively large demand for data and personnel to complete the RBI assessments.
Quantitative systems are generally even more demanding in terms of volume and detail of data required. RBI Quantitative Module is based on the standard developed by American Petroleum Institute (API) for the Quantitative Risk Based Inspections, API RBI 581. All calculation procedures and generic/historic data, along with reference tables and all the formulas are taken from the standard.
The results of the analysis are based on both the likelihood and the area/cost consequences of the equipment failure
|
The BowTie methodology is used for risk assessment, risk management and risk communication. This method is designed to give a better overview of the situation in which certain risks are present.
This structured method is used to assess risk where a quantitative approach is not possible or desirable. Risk in this methodology is elaborated by the relationship between Hazard, Top Events, Threats and Consequences. It combines the cause (fault tree) and the consequence (event tree).
It is simple and easy for the non- specialist to understand
|
RBI Expert is completely integrated into the PiMSlider 2011 suite of software modules. You can use it alongside any other PiMSlider 2011 module.
|
In most plants, a large percent of the total unit risk will be concentrated in a relatively small percent of the equipment items. These potential high risk components may require greater attention, perhaps through a revised inspection plan. |  |
A unique feature of ATP PiMSlider RBI Expert is the possibility to apply all known RBI approaches to date for different (or same) types of equipment in the same application: semi quantitative (configurable), fully quantitative (like API-581), qualitative (like BOWTIE). |
ATP PiMSlider RBI Expert allows the user to describe the Risk Factors and Calculation Models for Semi-Quantitative RBI, determine Degradation Mechanisms and Consequences for fully Quantitative RBI, describe Events, Threats, Barriers and Escalation Factors for BOWTIE. |

A function 'What If' has been realized for all the approaches, it allows simulating different behavior situations of models and input parameters, which provides the choice of the most cost-effective strategy for repairs and inspections.
With ATP PiMSlider RBI Expert, using only the configuration options, without changing the program code, standards such as API-580, API-581, DNV-RP-G101, DNV-RP-F116, DNV -RP-F206, BOWTIE, etc. have already been implemented, or can be implemented in no time.
