Resumen:
Containment enclosure bonds are typically designed to contain only 110% of the maximumstored tank capacity inside the bond. Moreover, the mechanical design of bonds normally considersonly the hydrostatic pressure efforts. However, after several accidents and experimental tests it was wellestablished that under some tank failure cases the stored liquid can easily overtops the bond containmentbecause of the energy of the released wave. This paper is concerned with computational fluid dynamicssimulations (CFD) conducted to investigate the efficiency of different bond designs and breakwatersunder several tank failure modes. Simulations were carried out using Volume of Fluid (VOF) to resolvescale laboratory models, for which there are some experimental data to assess the solver. The use ofbreakwaters showed to be a suitable way to reduce overtopping, avoiding the use of high bond walls orto move the bond away from the tank. Moreover, the incorporation of breakwaters induced significantextra mechanical efforts over the containment.
