Oil Pipeline Geotechnical Risk Monitoring Using FBG Sensors

ecopetrol_pipeline

A challenge that buried oil and gas pipelines often face is their susceptibility to accumulated strain, bending and possible rupture effects from soil movements and other geohazards. One example of a pipeline network currently combatting this issue is Ecopetrol in Columbia. In the spring of 2013, a system composed of Micron Optics fiber Bragg grating (FBG) strain sensors and several sm125 Optical Sensing Interrogators was installed by Salazar Ferro Ingenieros in order to provide early warning to Ecopetrol pipeline operators about possible pipeline mechanical bending or ruptured oil pipelines.

During the installation, over 300 Micron Optics os3155 temperature-compensated FBG strain sensorswere installed throughout 71 different critical geohazard sectors along Ecopetrol’s oil transportation pipeline network. The sm125 Optical Sensing Interrogators are used to monitor the sensors. For this project, Micron Optics FBG sensors were chosen because of their valuable advantages to the customer including their fast and easy installation, high accuracy, EMI immunity and resistance to mechanical fatigue. Since completion of the installation, two serious pipeline failures have been averted and multiple locations with accumulated strains have been identified and appropriate stress-relieving pipeline activities have been carried out, which has ultimately saved the customer millions of dollars in prevented pipeline ruptures and associated environmental remediation costs.
