Non-hydrostatic modelling of wave-induced loads on a restrained ship
Start a new DMP in Loading
The objective of this study is to develop a numerical model to simulate the wave-induced loads on a ship that is moored in a harbour or coastal region. The starting point of this study is an existing non-hydrostatic wave-flow model (SWASH). To study the wave-induced loads on a moored ship, we extended SWASH to include a restrained (i.e., nonmoving) ship. Preliminary results indicated that the extended model is capable of simulating the wave transformation in the vicinity of a restrained ship. Next, we wish to validate if this numerical model is capable of accurately predicting the wave-induced forces and moments on a restrained ship. For this purpose, we wish to compare model results with measurements from a laboratory experiment. The laboratory experiment was conducted in a wave basin of approximately 40m x 40m. In prototype scale, this is equivalent to a domain of 4km x 4km. At these scales, full three-dimensional simulations on a single processor range from hours to days, which clearly shows the need for parallel computing.
