The uneven and complex seabed bathymetry is the greatest feature of the marine environment close to the reefs. In this paper, the three-dimensional (3D) hydroelasticity analysis with varying shallow water depth is used to calculate the wave-induced motions and loads of a floating barge, considering the non-uniformity of the seabed. The influence of the complex seabed topography is investigated by comparison to uniform seabed representation. Through modal summation the 3D hydroelasticity analysis provides predictions of wave-induced loads, such as bending moments and stresses, in regular waves, as well as design waves. These predicted wave loads show that modelling the non-uniform seabed has a significant effect on the floating structures' service near islands, depending on water depth and seabed variability. Use of parallel computing which is very suitable in dealing with the large number of calculations involved in the hydrodynamic modelling of the complex fluid-structure interaction system, has significantly reduced CPU times.

Abstract

The uneven and complex seabed bathymetry is the greatest feature of the marine environment close to the reefs. In this paper, the three-dimensional (3D) hydroelasticity analysis with varying shallow water depth is used to calculate the wave-induced motions and loads of a floating barge, considering the non-uniformity of the seabed. The influence of the complex seabed topography is investigated by comparison to uniform seabed representation. Through modal summation the 3D hydroelasticity analysis provides predictions of wave-induced loads, such as bending moments and stresses, in regular waves, as well as design waves. These predicted wave loads show that modelling the non-uniform seabed has a significant effect on the floating structures' service near islands, depending on water depth and seabed variability. Use of parallel computing which is very suitable in dealing with the large number of calculations involved in the hydrodynamic modelling of the complex fluid-structure interaction system, has significantly reduced CPU times.
