Marine structures developed for marine industry and resource manifests different fluid characteristics. As such, the changes in the location, shape and size of these structures affect the fluid flow. Specifically, this wake flow caused by the structures result in environmental damage and topographical change. but on the other hand, protects harbor facility and environment. This study was conducted by changing the position of vertical plate in horizontal and vertical direction and experimented the variation of wake flow by PIV. This experiment confirmed the wake flow reduction by the changes of gab in horizontal and vertical direction. Particularly, the experiment showed that changes of gab in horizontal and vertical direction resulted in an increased u-velocity fields in the back of structure for larger horizontal gab.
