Condition Monitoring Locations (CMLs) are specified areas on piping and pressure vessels where thickness measurement examinations are performed to observe the presence and rate of damage and corrosion. These areas are also referred to as Thickness Monitoring Locations (TMLs).CML selection can be an arduous task; a systematic approach is needed to ensure effective inspections. Sometimes, inspectors or engineers do not consider expected damage mechanisms when selecting CMLs. Instead, they may decide to examine multiple locations, in the hopes of capturing degradation. This approach can lead to two issues: 1) excessive CMLs where damage is not likely to occur, or 2) not enough coverage where damage is likely to occur.

PinnacleART’s CML Optimization incorporates inspection history, corrosion expertise, and a statistical analysis to identify all susceptible damage mechanisms and where they are likely to occur. PinnacleART is also able to define the optimal extent, location, and technique needed to locate the damage, enabling effective inspections. We can also generate reports recommending the addition and deletion of specific monitoring locations. In addition, PinnacleART can gather all Condition Monitoring Locations (CML) data to be analyzed, use statistical analysis to evaluate the accuracy of the information, and make recommendations for cleanup.
Overall, CML optimization makes inspection efforts more efficient by focusing on those areas where degradation is likely to occur, and by eliminating unnecessary CMLs that will not provide value.
