The fields of speeds are received, distributions of pressure on walls of the pipeline and the character of failure of whirlwinds in a surface of a pipe is simulated. On the basis of the received results the value of hydrodynamical forces for the pipeline were designed. The values of hydrodynamical coefficients developed on the model, well enough coincide with values of laboratory physical experiments. The received results can serve for a rating of values of hydro-dynamical forces on the pipeline, diffusion of products of transport and characteristics of ero-sion of a ground under a pipe. Four series of physical experiments in wave tank are carried out. Are received and processed the results of influence of wave currents on two models of the pipeline. The com-parative analysis of the forces on the pipeline with the results of mathematical modeling is exe-cuted and the enough good conformity of these characteristics is shown.
