CBM Services

Condition based Maintenance ( CBM) techniques provide the reasoning and confidence to allow components to be 'changed on condition' rather than periodically and can underpin significant cost savings. In support of its plant and equipment reliability improvement initiatives, PCMS has developed a specific approach based on its expertise with a range of specialist technologies in the field of CBM, such as stress-wave analysis, ultrasonics, thermographic surveys and vibration monitoring. Many projects utilising these tools and techniques have been successfully undertaken including pinpointing component failures within underground tunnelling machines, ship's gearboxes and traction motors on railway rolling stock.

Our methodology is highly collaborative and projects usually start with a preliminary audit and CBM survey undertaken in conjunction with client engineering and operational personnel. Reports and recommendations, identifying the likely causes of low reliability, the key assets to be monitored and the most appropriate technique(s) to be employed, are submitted and discussed with management. After agreement, implementation is usually undertaken in two phases. The first phase focuses on the reduction in number of in-service failures and the second phase orientated to longer term actions to reduce (ppm) maintenance interventions and extend orrebalance maintenance and overhaul periodicities.
