| Résumé | The oil and gas platform in the nearshore and offshore region are sometimes vulnerable due to the extremely high waves approaching the structure. The bathymetry of such a region plays a vibrant role in modifying the incoming wave fields. Depending on the changes of bathymetry, the deepwater wave can change into a shallow water wave and could cause wave shoaling, modification in wavelength, and in many cases leads to wave breaking. After breaking the leftover wave energy is reformed and keeps propagating. A 3D dispersive numerical model is developed and utilized for the prediction of the wave reflection, diffraction, breaking, and propagation in the presence of varying water depth and an offshore oil rig. A finite difference method has been employed for the numerical computation that uses ADI (Alternating Direction Implicit) algorithm. In this work, a sea bottom of varying bathymetry is utilized extended from a deeper region to a shallower region may be treated as a natural or an artificial submerged obstacle or sea bottom. A square shaft of an oil and gas platform is located in the shallower region. In the simulation, a set of relevant regular and irregular waves are studied. Limited field data of irregular waves are used for model validation. |
