Abstract: For subsea structures in the coastal and offshore engineering, complex configurations are always equipped with horizontal and vertical beams inside, for example the subsea production system. It is believed that the structure porosity would be one of the key factors that largely affects the flow structures and the sediment transport. However, the previous studies always applied solid structures as a simplification. Little is known for the effect of structure porosity on the local scour. Hence the local scour around the finite high permeable structures, simplified as cubic porous caissons are shown in Fig. 1, was studied experimentally in this study.
