The PROGNOST®-NT Monitoring system features an automatic protection shutdown when a pre-defined number and level of critical signal levels has been reached within a compressor, in this case a hyper compressor.
The goal is to guarantee a cost-efficient operation by protecting the investment in the equipment and preventing downtimes of the system. The PROGNOST system delivers extensive data, allowing the reliability team to draw their own conclusions on the reasons for the shutdown and take appropriate action. This case study by PROGNOST Systems demonstrates a case where – after a safety shutdown – the reliability team was not consulted to do a thorough data analysis. As a result, the hyper compressor was re-started after it tripped which led to severe damage within the compressor.
