TL;DR: In this paper, the authors considered some aspects of water impact and green water loading by numerically investigating a dambreak problem and water entry problems, based on the Navier-Stokes equations that describe the flow of a viscous fluid.

TL;DR: In this article, a simulation model for the active control of U-tube anti-roll tanks is introduced and the fully nonlinear time-domain coupling of the ship motion and the tank water motion is established.
Abstract: Results of computer simulations of the water motion in ship anti-roll tanks are compared with experimental data. The numerical computations are done with a Volume of Fluid (VOF) based Navier-Stokes solver. Both free-surface anti-roll tanks and U-tube anti-roll tanks are considered. Calculated and measured results for the local wave heights, the sway force and roll moment are presented for both regular and irregular tank motions. A simple but effective simulation model for the active control of U-tube anti-roll tanks is introduced. Finally, the fully nonlinear time-domain coupling of the ship motion and the tank water motion is established.

TL;DR: In this article, a study of simulation of wave loading on a SPAR platform is described, which is based on the Navier-Stokes equations, discretised using a finite volume method.
Abstract: This paper describes a study of simulation of wave loading on a SPAR platform. The method used for the simulations is based on the Navier-Stokes equations, discretised using a finite volume method. The free-surface displacement is described by the VOF-method combined with a local height function. The regular head waves are generated using 5th order Stokes wave theory. To prevent reflections from the walls into the computational domain, a dissipation zone has been used where damping occurs by adding a pressure at the free surface. The results of the validation of regular wave loading on a SPAR platform are found to be very promising.
