We have studied the effect of strongly stratified flow forces generating internal waves on
elements of different structures in marine environment using both analytical and numeri-
cal approaches. We obtained integral representations for wave resistance and lifting
force affecting elements of the structures both in upper and bottom layers of stratified
flow. We carried out numerical calculations for real sea flows. We revealed conditions
for hydrodynamic reactions to elements of structures to achieve extreme values.
Keywords : stratified flow, wave resistance, lifting force, internal waves, underwater
obstacle.
