| Joint gravity surface waves and current effect on circular cylindrical obstacles of large transverse dimensions problem has been considered. Its solution is found by averaging of the initial 3D problem of diffraction of waves, transformed by a co-current or counter-flow, over the depth. The presence of the flow is shown to lead to a shift of the maximum loads and their significant increase for the counter-flow and decrease for co-current flow. Also it is shown that for a submerged cylinder or a monopod for the counter flow and sufficiently short waves it is possible the situation when the load direction doesn't coincide with the direction of wave propagation. |
