WAVE-CURRENT EFFECTS ON LARGE OFFSHORE STRUCTURES

The various effects that influence loads acting on a large offshore structure due to the combination of waves and currents are reviewed. These may be broadly associated with potential flow effects and viscous effects. The potential flow effects are nonlinear and may generally be investigated by perturbation or time-stepping methods. Viscous effects include the onset of flow separation, which affects the validity of the assumed potential flow, as well as steady and oscillatory forces. The fluid mechanics of the complete wave-current-structure interaction problem are not yet well understood and areas in need of additional research are identified.
