API 580 Course — Risk-Based Inspection (RBI) Training per API RP 580/581

Risk-based inspection according to API 580 / API 581 (American Petroleum Institute API) is a process of controlling main technological equipment with proper understanding by technical supervision inspectors of modern knowledge and skills in risk-based inspection, as well as detailed understanding of calculations performed according to API 581 data for pressure equipment.

Implementation of risk-based inspection in the oil refining industry provides advantages in ensuring safety and economic feasibility.
