Modern, online diagnostic and monitoring systems are great things to have for safe and reliable machinery operation. Condition based maintenance, increase of uptime, efficient repairs and short MTTR with maximum MTBM – all these concepts and goals can be realized with state-of-the-art technologies and services.

Bridging the Gap

In the process industry, it is still common that users strictly separate machine protection equipment from condition monitoring. Machine operators frequently face a time-consuming troubleshooting based on minimum diagnostic data e.g. from the DCS system. For many years, flight data recorders have been a common standard in the aviation industry to perform post-incident analyses of aircraft accidents. Such transient data recorders are also available for machinery protection systems. Captured data can be used to improve the traditional snapshot monitoring program and support cost-efficient condition monitoring purposes without waiting for an analyst to come.

Purpose and terminology of condition monitoring systems for recips

The only way to ensure safe, reliable, efficient and economical operation of reciprocating compressors is to monitor them continuously and to take appropriate action based on the information the monitoring systems provide. That simple objective, however, is difficult to put into practice. The variety of instruments, systems and methodologies for machine monitoring and diagnostics can be perplexing. Descriptions and claims are sometimes similar, often conflicting and almost always confusing. This plain-language guide to system selection is to help provide clarity for the decision process. It lists the essential capabilities a system should have and explains why those capabilities are needed.

Early, Automatic, Online Failure Detection

In December 2007, the online monitoring system avoided a major and cost-intensive damage at one compressor. The permanent piston rod position monitoring detected a cracked respectively a virtually broken piston rod at the 1st stage. Prior to a complete rod failure, the machine had been automatically stopped and costly consequential damages have been avoided.
