Some aspects of integral grahage method application for description of features of deep-water draining of oil products in case of marine pipelines damage

The author uses a mathematical model describing the propagation of a multiphase flooded jet caused by the damage to the oil-producing structure or the marine pipeline used for the transportation of hydrocarbons. The flow features of multiphase and single-phase (gas) jets are studied. The author also studied the effect of hydrate formation on the jet parameters. The integral Lagrange method is used to calculate the thermophysical parameters. As a result of these calculations, the author obtained the dependences of temperature and velocity on the vertical coordinate. Data analysis of dependencies allows predicting jet behavior and study the possibilities of application of devices for leak detection
