RBI- Risk Based Inspection

The iRiS System RBI software suite consists of the following software modules:

1. API 581 qualitative analysis (unit-based) system for unit-based approach (screening)
2. API 581 qualitative (component-based) Level 1, semi-quantitative – Level 2 and quantitative – Level 3 analysis modules
3. Management System Evaluation Module (MSEQ)
4. Risk-based decision making tools
5. Damage mechanism identification and analysis
6. EN Risk Based Inspection Framework / RIMAP-based assessment (option to be agreed with the end-user in each particular case)

API 581 qualitative analysis system for unit-based approach (screening) – QLTA:

R-Tech’s QLTA is based on the Workbook for Qualitative Risk Analysis given in Appendix A of the API581 Base Resource Document

QLTA is used to determine the Likelihood and Consequence Category for a given unit. Depending on the nature of the chemicals in a unit, the Consequence Category can be determined based on the flammable or toxic hazards for the unit. Flammable consequences are represented by the Damage Consequence Category due to the primary impact of a flammable event (fire or explosion) is to damage equipment. Toxic consequences fall under the Health Consequence Category due to their impact is usually limited to adverse health effects.

API 581 qualitative (component-based) – level 1, semi-quantitative – level 2 and quantitative – level 3 analysis modules

iRiS-Petro performs all the tasks necessary to determine the risk rank of the equipment and optimize the inspection plan, according to API581, based on the qualitative approach (level 1), semi-quantitative approach (level 2) or quantitative approach (level 3).
