Abstract: An evaluation of wave-induced pore pressures and effective stresses has been recognized by marine geotechnical engineers as an important factor in the design of offshore pipelines. Most previous investigations for the wave-seabed-pipe interaction problem have not considered the material of the pipeline. Thus, the internal stresses and deformation of the pipeline have not been investigated in the wave-seabed-pipe interaction problem. This paper considers the pipeline itself as an elastic material and links the analysis of the pipeline with the wave-seabed interaction problem. Based on the numerical results presented, the effective stresses in the angular direction σθθ and shear stress τ within the pipe are much larger than the wave-induced pore pressure.
