Abstract

There are situations when there is a breakthrough of a pipeline with oil products under water. As a result, oil spills on the surface, polluting the environment. Underwater currents and wind can carry an oil stain away from the point of leakage. Therefore, it is not always possible to visually determine the location of a pipeline break by a spot of oil on the surface.To solve such problems, it is proposed to install strain sensors along the pipeline, which take the values of the displacement derivative ∂u(x,t)/∂x (deformations) at different instants of time, and use the simplest model of a pipeline based on the equations of longitudinal oscillations of a homogeneous rod. Formulas for determining the moment and location of the pipeline rupture were obtained from the strain sensors data and a scheme of interaction with GLONASS was proposed that allows instantly detecting leaks and damages of pipelines laid under water and timely eliminating the consequences of the accident. The application of the proposed scheme minimizes the consequences of the accident for the environment and financial costs.
