Please note that (i) the stiffness and hydrodynamic coef cients for the mooring chain have not been experimentally determined but are taken as standard values (DNV, 2010), and (ii) the fore and aft mooring lines were not of equal length in the experiments because of the constraints...

... that the assembly of mooring lines and oater has different structural properties in the simulations and in the experiment. Regarding the other two degrees of freedom, the amplitude of the heaving motion in the CFD results damps out faster than the experimental one. In fact, the amplitude of the motion remains...

... is presented in Fig. 12 in comparison with the experimental data. The time instant of the wave attack of SPH is ahead of the experiment, but the moment of the second peak matches the experiment generally well. In terms of the predicted pressure values, the peak pressure values at FP3 are overestimated compared...

...). Therefore, it is presumed that the impact is not signi cant when in contact with adjacent caissons; however, the extent of this in uence should be veri ed through model experiments or on-site investigations, which is desirable. EXPERIMENTAL CONDITIONS Breakwater Model In the model experiment, a rectangular...

..., such that the required modelling coef cients (e.g., elastic moduli, Poisson s ratio, and coef cient of permeability) can be adjusted and basic model assumptions can be veri ed. To that end, small-scale experiments in an experimental wave ume at the Institute of HydroEngineering of Polish Academy of Sciences have been...

...-to-Sequence models are proposed and used to compare the PFN model, Long Short-Term Memory model, and Convolutional Neural Network. Three different groups of model experiment data are used for comparison. Results show that PFN has advantages in real-time prediction of parametric roll motion due to its time...

... the full-scale case study (Fig. 4) is slightly different. At a location close to the seawall (i.e., Dw/d = 1 9512) (Fig. 4a), the experimental result shows a similar wave pattern as what has been observed in the scaled experiment; however, the corresponding numerical results do not show a clear double...
