| Abstract: | For the response of an undisturbed seabed to water waves there exists a number of solutions. Based on the concept of linear consolidation theory they all lead to the result that the pore pressure satisfies the Laplace equation, at least when incompressibility of the pore fluid is assumed. This suggests that the flow around an embedded object, e.g. a submarine pipeline, is also governed by the Laplace equation, either exactly or approximately. In this paper a number of such problems is solved using complex function theory and the technique of conformal mapping. The hydrodynamical force is calculated from the solution for the pore pressure. A good agreement is obtained with existing solutions. A comparison is also made with a numerical solution based on the finite-element method. It is concluded that the hydrodynamical force acting upon a submarine pipeline is about ten to thirty percent of the buoyancy of the pipe depending on the maximum wave load and the burial depth. |
