Risk Based Inspection analysis (RBI analysis)

For the components that need the detailed quantitative analysis, RBI includes all of the equipment and components listed in the American Petroleum Institute's RP 581 document for risk-based inspection technology. This includes compressors, heat exchangers, pipes, tubes, tanks, HEXTUBEs and pressure relief devices. When adding a component, the software provides a wizard that guides you through the steps of defining the general properties and selecting the applicable damage factors. You can then enter the relevant damage factor properties and consequence properties and finally generate the results.

  • Quick qualitative risk assessment
  • Select and describe the damage factors
  • Describe the consequences of failure
  • Generate the RBI results

Quick qualitative risk assessment

You can configure the risk discovery ratings feature to provide a quick qualitative RBI analysis that can save time and effort by estimating an asset's importance in terms of risk. By doing this quick assessment, you can focus your limited resources (both time and money) on those assets that pose the greatest risk, both physically and financially.

Reuse existing analysis data or phrases

The software provides an array of tools to help you find and reuse descriptions from any existing analysis and to select phrases from predefined templates or phrase libraries. You also can use fully customizable Excel® templates to quickly import system configurations and/or analysis data from external data sources.

For the specific components that are eligible for RBI analysis (compressors, heat exchangers, pipes, pressure vessels, pumps, tanks and pressure relief devices), the software guides you to select the specific equipment and component type that will determine which analysis inputs are required. For other types of equipment that might receive only RCMFMEA or a related analysis, it is easy to add the items one at a time. To save time and ensure consistency, you also have the option to automatically import system configuration data from an external Bill of Materials file or from XFRACAS (web-based FRACAS).

Data management systems score for the plant

Because the procedures and personnel in a specified plant will affect the risk, the RBI analysis method includes an adjustment factor that accounts for the influence of the plant's supervisors and management on the mechanical integrity of the plant equipment.

It is easy to set and adjust this factor for any given analysis project with three options:

  • The software can guide you through the detailed assessment recommended by the API standard and calculate the score for you.
  • If you have already performed the assessment for a prior analysis, you can quickly enter the score without having to repeat the full questionnaire again.
  • You can start with an average score until you have the time and knowledge to complete the full assessment.

Full-featured RCM analysis

RBI provides full-featured support for Reliability Centered Maintenance (RCM) analysis, which can be used independently or in conjunction with your RBI analyses.

Equipment selection
In order to focus resources where they can provide the greatest benefit, the Risk Discovery Analysis feature provides a choice of two configurable methods to determine which equipment will be analyzed with RCM techniques.

Functional failure analysis
The Analysis panel makes it easy to switch back and forth between three complementary views of the functional failure analysis information so you can choose the display that is best suited for your current activity.

  • FMEA Hierarchy displays a lot of information in a compact space. You can also choose to display and enter causes before effects, if desired.
  • Worksheet View allows you to type directly in the worksheet cells and tab through the analysis as you would in a spreadsheet application such as Microsoft Excel.
  • Filtered View allows you to generate sortable lists of records of a particular type.

Failure effect categorization and maintenance task selection
The software supports the failure effect categorization (FEC) and maintenance task selection logic charts in the major industry RCM standards. You also have the option to customize the questions, categories and task types to fit your own specific analysis procedures.

Task Packaging
The Task Packaging feature makes it easy to group individual tasks into packages based on factors such as time, task type and areas in the system where tasks are performed. You can manually assign a task to the appropriate maintenance package or allow the software to automatically group tasks based on the criteria that you have specified for each package. This tool makes it easy to experiment with different intervals and provides a graphical chart to help you visualize the packages that are under consideration.

FMEAs and related analyses

RBI provides a complete set of features for FMEA and related analyses, which can be used independently or integrated with any RCM or RBI analysis.

Risk priority numbers and criticality analysis
Risk Priority Numbers (RPNs) are calculated automatically based on your selections from fully configurable rating scales. The software supports related metrics, including SxO (Severity x Occurrence), SOD (Severity, Occurrence, Detection) and SD (Severity, Detection).

The Priority Highlights feature allows you to highlight issues in the interface and report/query output based on specified criteria. The software facilitates both quantitative and qualitative Criticality Analysis.

Tracking the completion of recommended actions
One of the most expensive mistakes among FMEA practitioners is the failure to properly follow up and track the completion of recommended actions. The software provides multiple features to make sure that your organization implements necessary improvements to reduce the risk in the product/process design. This includes targeted reports, charts and the ability to send automated notifications via e-mail.

Change log and electronic approval tracking
When an authorized user activates the change log for a particular FMEA or DVP&R analysis, the software will record a history of the specific changes made in each tracked revision. In addition to the date/time and details of the change, the software can be configured to prompt users to record an explanation for each modification. If desired, this utility also can store an electronic record of the users who have reviewed and approved each tracked version of the analysis.

Support for related analyses
The software provides configurable utilities for:

  • New Test Plans feature (generated automatically from relevant actions in the FMEA)
  • Design Verification Plans and Reports (DVP&Rs)
  • Process Flow Diagrams (PFDs)
  • Process Control Plans (PCPs)
  • Design Reviews Based on Failure Mode (DRBFMs)

Queries, reports, charts and diagrams

RBI provides a complete range of options for presenting your analysis data in ways that will effectively communicate results and facilitate decision-making.

  • Configurable queries and print-ready reports to manage predefined and customized templates that can be made available to all database users, applied to any data set and incorporated into any print-ready report document.
  • The Query Utility window is a powerful analysis tool that makes it easy to find and open specific sections of the analysis. It is also a flexible custom reporting tool that allows you to create and manage saved queries that meet your presentation requirements.
  • The Reports window makes it easy to build report documents that include the predefined report forms, custom report forms and/or custom queries that will be most effective to present your analysis results. Since you can generate these documents directly in Microsoft Word or Excel, it is easy to customize and distribute reports without a specialized report editor or viewer.
  • In addition, if your organization chooses to implement a SEP web portal for an enterprise database, you can also publish these reports to the portal (in Word, Excel, PDF or MHTML format), where they can be accessed from any web-enabled device.
  • Graphical charts and relationship diagrams with flexible options to create attractive bar charts, pie charts and matrix charts based on the analysis data. The software also generates Cause and Effect Diagrams and Failure Relationship Diagrams to help you visualize the relationships between issues in your analyses.
  • FMEA/FMRA dashboards to create customized dashboards to present data from FMEA and FMRA analyses in XFMEA/RCM++/RBI. In addition, if your organization chooses to implement a SEP web-based portal for an enterprise database, you can share selected dashboards to be accessed from any web-enabled device.
