Risk-Based Inspection and Maintenance Strategies

Introduction:

In an organization, Risk-Based Inspection (RBI) and Risk-Based Maintenance (RBM) approaches are structured methods for evaluating the probability and impact of equipment and infrastructure failures. These strategies allow for prioritizing and optimizing inspection and maintenance activities, enhancing safety, reducing equipment malfunctions, minimizing unplanned shutdowns, and lowering operational costs. Understanding these risk-based strategies is essential for developing effective maintenance and inspection procedures.

The Risk-Based Inspection and Maintenance Strategy course is designed to provide participants with a thorough understanding of RBI and RBM concepts, risk assessment methods, and practical applications. The course covers how to determine optimal inspection and maintenance actions based on risk profiles, aiming to develop proactive maintenance plans that improve safety, reliability, and cost-effectiveness.
