api rbi software


The only official API software – documented in the public domain in API 581

Developed as a Joint Industry Project by members from the major refining and petrochemical companies, API RBI software technology was vetted and standardized through the API consensus balloting process, ensuring approval and acceptance by industry experts worldwide. API RBI is fast becoming the de facto international standard.

The core API RBI technology has been updated and improved to produce more accurate risk calculations. Its use has been broadened to other industries, materials and process applications beyond pressure vessels and piping. Integrated standalone modules include fixed equipment, heat exchangers, atmospheric storage tanks, and pressure relief devices.

  • Integrates quantitative & qualitative risk analysis
  • Most extensive materials properties electronic library available
  • Full fluid & consequence modeling capabilities
  • Numerous technical modules including fixed equipment, HE bundles, ASTs and PRDs
  • Developed by ANSI-approved consensus
  • Defendable to regulatory authorities

Software analysis capabilities

  • Planning module based on probability of failure, safety and financial risk providing a recommended inspection date and plan
  • A wide range of damage mechanisms covering refining and petrochemical applications
  • ASME Code tmin calculations for vessel components and piping, structural tmin specification, and/or input of user-defined tmin
  • ASME Code material specification database covering allowable stresses and engineering properties of base and overlay/clad materials
  • Time stamping of risk calculations to facilitate use of data from existing plant integrity database systems
  • New state-of-the-art fluid property modeler that uses algorithms that are more robust and accurate to calculate the properties of two-phase fluid mixtures over a wider range of operating conditions
  • User-defined process streams created from a fluid property database of over 1,800 fluids compiled from such sources as the industry-standard DIPPR database, which is regularly tested and updated for accuracy
  • Data import/export and synchronization capability for reporting and initiating new studies, including inspection planning
  • Finger-tip diagnostic reports showing full derivation of all risk analysis
  • Translation tool for upgrades from older software versions
