Slurry Slurry pipeline is a vital equipment for medium transportation. Although the current pipeline transportation technology has been improved, the leakage accidents still occur frequently, which can easily cause great environmental pollution and economic losses. Although there are many technologies to accurately calculate the leakage position, they are only suitable for stable transportation conditions of homogeneous slurry. In view of the large fluctuation of the slurry pipeline transportation pressure, flow rate and concentration, The existing prediction methods of the leakage position is only suitable for stable conveying conditions of homogeneous slurry and gas. To achieve accurate real-time warning for leakage, a pipeline transportation resistance monitoring system (TRMS) is developed. Based on the monitoring pressures along the pipeline, a real-time prediction algorithm of leakage point based on the transportation resistance of the whole pipeline section is established. Based on the new method, an experimental facility is deployed in a dredging project and field experiments are carried out. The application results prove that the leakage phenomenon is effectively forewarned, and the real-time & high-precision leakage point prediction is realized, which reduces the environmental risk and economic loss caused by the leakage. Finally, the methods are verified and applied to the pipeline leakage. The methods realize real-time and accurate judgment of pipeline leakage phenomenon and its location. The error of the prediction is about 2%, and the delay of prediction response can be ignored.
