MEA has extensive knowledge and experience with geotechnical related analysis of the performance of buried and exposed pipelines. Various expert risk analyses and mitigation designs have been performed by MEA including computational investigations of buried, high-pressure natural gas and petroleum pipelines affected by ground movement. Investigation and risk analysis services provided by MEA are as follows:
Investigation of the effect of mine subsidence on pipe stresses and deformations
Evaluation of landslide or slope instability hazards to pipelines
Mitigation design of buried pipelines to reduce the hazard of failure due to ground movement
Stress monitoring of pipelines using telemetric strain-gauge instrumentation from ground movement
Investigation of soil-pipe interaction
Pipeline investigation in seismic conditions
Numerical analyses of pipelines for special investigations using state-of-the-art engineering programs including SAP2000 and FLAC3D
