Carrying out of systematic control of oil and gas pipeline condition is important for provision of normal operability of hydrocarbon transporting system. Implementation of monitoring of pipelines condition using traditional methods requires a lot of material and labour resources. The most important alternative is utilization of unmanned aerial vehicles equipped by lidar. The accident at the pipeline may occur due to such causes as leak, rupture, denture, other causes and unknown ones. The potential accuracy of suggested method for lidar-thermal remote control of route of underground pipeline lay out is analyzed. The possibility for increasing of accuracy of identification of underground pipelines by way of decrease error of identification on two signatures is considered. The chosen signatures are geometrical coordinate at the horizontal plane defined by thermal sensing and vertical coordinate determined by laser measurements. It is determined that by cause of hydromechanical processes occurred in soil within imits of route the shift of pipeline and increase of soil layer level over the pipeline take place. These effects form the total uncertainty of determination of accurate coordinates of pipeline from the board of carrier of laser and thermal sensor. It is shown that performed optimization allows to increase the geometrical accuracy of route determination using suggested method of laser-thermal sensing. |
