Force and water jet impact reduction on adjacent structures by means of free surface breakwaters

In head waves, water jet impacts due to run up can occur as a result of the structural configuration of some floating structures, reducing workability. Wave attenuation near the floater may reduce the risk of water jet impacts. This paper presents a numerical study of the performance and attenuation mechanisms of various plate type fixed free...

Investigation of crown wall stability on top of rubble mound structures with OpenFOAM®

In the present study the stability of crown wall elements on top of a rubble mound breakwaters is investigated. The first step was conducting a literature review, in order to identify knowledge gaps. It was found that current design methods do not take the freeboard of the crown wall into account when calculating the vertical force acting on it....

Numerical simulation of extreme wave impact on offshore platforms and coastal constructions

The simulation tool ComFLOW, developed for accurate predictions of hydrodynamic wave loading, is based on the Navier-Stokes equations. The free-surface dynamics is described through VOF, with local height-function approach to enhance accuracy. Numerical reflections are prevented by specially designed absorbing boundary conditions. Gravity...
