A floating barrier system has a plurality of connected floating barrier units. Capture net segments are positioned on the floating barrier units by support post members, forming a barrier to vessel passage. Lanyards attach the ends of the capture net segments to the floating barrier units. Upon a vessel striking the capture net segments with sufficient force, the capture nets detach from the support post members and/or pull the support post members over, and the forces from the vessel are transferred via the lanyards to the floating barrier unit. The vessel is prevented from fully passing over the floating barrier unit, thus itself forming a barrier to passage by other vessels.

A storage structure is configured to be buoyant or retained above a water line. The storage structure includes a frame having a back beam, a left beam attached to the back beam, a right beam attached to the back beam and a front beam attached to the left beam and the right beam to form a substantially rectangular configuration, wherein prior to a last of the beams being secured together an interior space accessible through an opening. The storage structure includes a bladder configured to be positioned through the interior space though the opening wherein the bladder is sized to be retained within the interior space whether the storage structure is above the water line or buoyant, the bladder including a vent, a fill port and a drain wherein an amount of water within the bladder is manipulated to provide ballast or buoyancy to the storage structure. The storage structure includes at least one floor panel secured to the frame over the bladder, side walls extending from a perimeter of the floor panel, wherein one side wall includes a door for ingress and egress to the storage structure. The storage structure includes a roof attached to the side walls.

The present invention relates to a detachable harbor edge protector, and a detachable harbor edge protector according to an embodiment of the present invention includes a bottom plate of which a cross section is formed in a curved shape and which is fixed to a stepped ground surface, one or more fixing parts which fix the bottom plate to the ground surface, an upper cover detachably coupled to an upper portion of the bottom plate, and a side cover coupled to a side surface of the bottom plate. Accordingly, since the bottom plate and the upper cover are detachably formed, maintenance can be easily performed when damage occurs.
