Hampering motion floating structure

Abstract

A floating structure includes a water pollution preventing membrane having a float part extending so as to define a water area, and a curtain part suspended at a lower end of the float part to define the water area in water. A float net having floatable ropes anchored to the float part and knitted into a lattice with a predetermined mesh size is disposed in an outer water area defined by the water pollution preventing membrane. Of the ropes constituting the float net, the rope which is disposed in parallel to the float part has a light reflection rope and a support rope for supporting a trap net suspended into water. The propeller of a watervehicle moved into the float net is caught by part of the ropes or the trap net to prevent the watervehicle from approaching the water pollution preventing membrane or an inner water area.
