Modeling of Internal Wave Impact on Hypothetical Pillars of Hydraulic Engineering Constructions in the Conditions of the Sakhalin Island Shelf
Authors: Ekaterina Rouvinskaya, Oxana Kurkina, Andrey Kurkin, Andrey Zaytsev
Abstract: The velocity field induced by nonlinear internal waves generated by multicomponent barotropic tidal flow over topography for the conditions of the Sea of Okhotsk (South-East shelf of Sakhalin Island) is used to estimate dynamical loads on underwater vertical cylindrical parts of marine engineering structures. The intensity of lateral surface pressure and the rate inertia moment are expressed according to Morison’s formula for a cylidrical pile of 2.5 m diameter and 100 m height and computed as functions of time. They can reach values of 1.9·105 N and 10 MN∙m, respectively, during the flood phase of the tide.
