SIMULATION OF PIPELINE VIBRATION AND SCOUR
A vertical two-dimensional numerical model has been established to study the flow and scour around offshore pipelines. The Reynolds-averaged Navier-Stokes equations, pressure Poisson equations and turbulence equations are solved using a second-order accurate finite difference scheme formulated on a curvilinear coordinate system. In the hydrodynamic computations, forced vibrations are specified to an isolated pipe either in still water or under steady current, hence the flow around and forces acting on the pipeline are predicted. By incorporating the sediment transport and bed deformation models into the flow solver, the scour and self-burial around a fixed pipeline have been simulated. The computed results agree well with the experimental data, showing that the model is useful in studying the interactions between the pipeline, the surrounding water and the seabed soils.
