Steam systems, once regarded as secondary components in industrial plants, are now formally recognized as critical assets within Risk-Based Inspection (RBI) programs. The latest edition of API 581 broadens its scope to include essential steam-related equipment such as steam traps, heat exchangers, turbines, tracing systems, and steam-assisted flares. This updated methodology provides a structured framework for assessing the probability and consequences of failure in these components, enabling more precise and data-driven inspection planning. By focusing on high-risk areas, it enhances system reliability, improves energy efficiency, and reduces operational costs. The inclusion of steam systems in RBI marks a significant advancement in comprehensive asset integrity management.

This presentation will showcase risk assessments for steam systems across a range of industrial applications, aligned with the API 581 methodology. Real-world case studies from sectors such as petroleum refining and petrochemical manufacturing will illustrate practical implementations. Examples will include potential failure events due to water hammer in steam distribution lines and heat exchangers, as well as unexpected operational disruptions in steam turbines and critical tracing lines.

Attendees, such as plant inspectors and utility engineers, will gain a deeper understanding of the key factors that influence risk estimates for steam system assets. Additionally, recommended mitigation actions and their impact on recalculated, mitigated risk levels will be discussed from the perspective of a steam system specialist.
