PipePatrol Stress Monitoring

Pipelines are constantly working under mechanical stress during normal operations and load cycles. External influences, such as temperature extremes, mechanical shock or vibrations, can increase the local line pressure. Any design pressure violation can have a major effect on the pipeline lifetime. Modern regulations often now require operators to document and evaluate these effects.

This PipePatrol solution performs stress monitoring of the pipeline without human interaction and hence provides the base data for an assessment of the remaining pipeline service life. The software monitors the pressure measurements at sensor points along the pipeline and compares them with the pressure levels according to DIN 45667 and in line with regulation TRFL 2017. These results contribute predictive maintenance planning, to ensure the necessary integrity check is done before critical conditions occur.

Highlights

• Provides the base data for the assessment of pipeline ageing to calculate the remaining service life
• Monitors design pressure violations and load cycles at each measurement point
• Records pressure cycles to plan for the next integrity check
• Pressure cycles are counted according to industry standard DIN 45667

Typical applications

• Crude oil pipelines from oil fields to refineries
• Multiproduct pipelines from refineries to tank farms
• Subsea pipelines from FPSO units and platforms
• Non-continuously operated transport pipelines (e.g. for jet fuel)
• Water pipelines from desalination plants to cities
• Natural gas pipelines
