Risk Based Maintenance (RBM) is a maintenance strategy that uses risk assessment to determine the best maintenance plan for a particular asset. It is a proactive approach to maintenance that takes into account the potential risks of a system or equipment failure and then develops a plan to mitigate those risks. The goal of RBM is to optimize the use of resources while ensuring the highest level of safety and reliability. The risk assessment is based on the criticality of the asset, the likelihood of failure, and the consequences of failure. This approach helps to identify the most cost-effective maintenance plan and reduce the likelihood of unexpected downtime. RBM is an important tool for any organization that wants to maximize the life of their assets and ensure their safety and reliability.
