Answers. Options. Choose Safety.

Knowing when, where, and how to inspect assets will improve the overall safety and reliability of your facility. You can remove uncertainty by evaluating your equipment and refocusing inspection efforts to the highest-risk items.

With API RBI software, the industry’s only fully compliant API 581 calculator, you will plan maintenance strategies efficiently and accurately, and systematically factor risk into your decision-making process. Optimize your inspection plan with API RBI.

API RBI software supports successful quantitative risk-based inspection (RBI) studies by providing guidance for each component to account for applicable damage mechanisms and recommending an inspection plan, based on risk. 

Quantitative Approach (API 581) Qualitative Approach
API RP 581 uses a quantitative approach to implementing RBI, accounting for the probability of failure (POF) and the consequence of failure (COF) for each piece of equipment in a process unit. API RP 580 is a risk-based inspection (RBI) document that identifies the basic elements for developing, implementing, and maintaining an RBI program.
Key Considerations:
  • Results produce the POF, COF, and risk numbers based on data collection and sound technology
  • API 581 details the recommended procedures, tables, and calculation methods required to perform a successful quantitative RBI analysis
  • Data driven results are repeatable and maintainable, independent of the RBI team
  • Data changes are fully auditable to support an evergreen RBI program
Key Considerations:
  • Successful RBI analyses depend largely on the team and their expertise
  • Results are often too generic to correctly define an auditable inspection or maintenance plan
  • Difficult to achieve accuracy and consistency between multiple qualitative RBI studies, due to varying skillsets over time
  • Results are not easily repeatable or maintainable
Choose API RBI software, the industry’s only API-branded RBI tool, as the foundation for all your quantitative RBI projects. API RBI is current to API 581 Edition 3 Addendum 2 and is also available in Spanish.

Summary Report Sheets

Quickly and easily develop custom inspection reports to share information with other members of your team.

  • Create or update reports to include custom content using Microsoft® Excel® templates
  • Dynamically update and configure all the existing summaries in MS Excel
  • Include custom content with the PlantManagerTM keywords report sheets
  • Configure all labels, design, and formatting in MS Excel and utilize all the formatting options and macros

RiskBI — Data Visualization

Gain greater insight into your operations and performance and quickly identify trends and problem areas. RiskBI, using Microsoft® PowerBI, dynamically updates to help unit inspectors and corporate executives visualize inspections to support faster and more informed decision-making.

  • Compare RBI assessments across several units in a facility to understand the differences and similarities between each unit
  • Compare facilities’ corrosion rates and how they fall on the risk matrix,
  • Identify when multiple equipment is due for inspection, which components are overdue, when equipment will hit minimum thickness, and how to reduce risk with inspections

Damage Mechanism Screening

Estimate your equipment’s susceptibility to the most common damage mechanisms in the refinery industry using the damage mechanism screening tool. This feature uses the damage solver, which is based on API 571, to:

  • Filter potential damage mechanisms based on process unit, material of construction, temperature, damage source, and morphology
  • Implement a damage screening assessment without relying on in-house materials and corrosion experts
  • Assign corrosion rates and cracking susceptibilities based on the judgement of industry experts

Inspection Planning

The inspection intervals methodology identifies the high- and low-risk equipment at a facility, allowing you to focus future inspections on the highest risk equipment to reduce costs and overall risk.

  • Set a maximum interval and recommends re-evaluation of the RBI study at a minimum of every 10 years
  • Calculations are not limited by or based on half-life calculations or prescriptive interval approaches
  • Choose from multiple options for inspection effectiveness, including how much each option will reduce risk and effect on future target dates 
  • Select inspection target dates for each damage mechanism rather than the superposition method to calculate target dates

You will learn how to use API RBI software, including developing skills in navigation and application. The course helps you understand API RP 581 technology and how to interpret its calculated results to help develop an effective RBI program. This training course can be offered virtually or in-person and may be customized to meet your corporate objectives.
