Conditions for Long-term Monitoring of Safety in Operation of Pipelines

Abstract

The safety of the high-pressure pipeline systems can negatively affect occurrence of non-standard operational states. This can primarily occur in operation of turbo-compressors at the compressor stations, where we can expect an unwanted vibrating due to existence of the dynamic loading. Let us have another case, the line parts of such pipelines, where the walls could sometimes be weakened by the unwanted corrosion defects. In both cases, the safety of operation can be exposed by additional bending loading of the pipeline e.g. due to decreasing of sub-soil. In this contribution will be introduced monitoring systems which can monitor such negative events in a real time. More closely will be explained selection of suitable sensors and their deployment along the critical place as well as evaluation of measured data and conditions for valuation of the operational safety. Furthermore, there will be presented results obtained from measurements of existing real monitoring systems of safety for given pipeline systems.
