A modular interlocking flotation assembly for selective creation of a raft includes a plurality of shells. Each of a plurality of couplers is coupled to a respective shell so that the shells of the plurality of shells are selectively interconnectable in a substantially planar configuration. The plurality of shells thus interconnected is configured to function selectively a raft and a portable dock.

A quay wall absorption block includes a back wall, a cap, and a half columnar wall extending between the back wall and cap. The half columnar wall defines a plurality of chamber surfaces and mating surfaces on opposite sides thereof such that the chamber surfaces define portions of a plurality of closed-end flow chambers on opposite sides of the half columnar wall when the mating surfaces are in contact with corresponding mating surfaces of other quay wall absorption blocks. The half columnar wall also defines a plurality of flow paths that extends therethrough to fluidly connect the plurality of closed-end flow chambers on opposite sides of the half columnar wall.

A floating dam or island is provided by pre-fabricating modular hollow bodies. A first group of modular bodies is laid floating on a water surface, positioning the modular bodies in mutual side-to-side arrangement so as to delimit therebetween intermediate gaps within which the reinforcing rods are protruding. A first concrete casting is performed into the gaps and over the modular bodies so as to render them mutually joined. A second group of modular bodies is then laid over the first group and a second concrete casting is performed in order to join the first and second group together. Additional groups of modular bodies are laid and further concrete castings are performed up to obtaining a monolithic block having a desired floating dam or island configuration.

A water area may be sheltered by installing, at an active boundary of the water area, a plurality of shields mounted on posts, each shield having a lower edge immersed in the water. Each shield may dissipate at least a portion of wave energy approaching the active boundary of the water area. One or more piers may be positioned within the sheltered water area or basin.

A water wave breaker includes an attachment portion and a curved concave portion. The curved concave portion is connected with the attachment portion. When the attachment portion is attached to a substantially vertically extending surface a first end of the curved concave portion, which is disposed laterally farther away from the attachment portion than a second end of the curved concave portion, is disposed above the second end of the curved concave portion with the curved concave portion oriented in a downward direction away from the substantially vertically extending surface.

A combination float and bracket assembly for a floating structure that includes a float body made of foam with a plurality of transversely aligned L-shaped brackets that extend upward from the float body's top surface. Each bracket includes a horizontal flange and a vertical flange and the foam body is made of closed-cell foam. During manufacturing, a plurality of bracket cutouts is formed in the top surface of the float body. A brackets is then inserted into each bracket cutout. The bracket's vertical flanges extends upward above the top surface. Connectors are used to attach the vertical flanges to a frame member. In one embodiment, a transversely aligned frame member void area is formed in the float body adjacent to the vertical flange. The void area receives the frame member that extends over the top surface of the float body and attaches to the vertical flange. Also disclosed is a floating structure that includes a frame attached to a plurality of float and bracket assemblies.

A convertible capping system and methods of use thereof for capping a top portion of a sheet piling wall or other structure. A top panel of the capping system includes a widthwise spaced array of longitudinally extending parallel connection ribs, and defines an initial width at least equal to or greater than an intended final width, whereby a user can cut the top panel down to a desired final width corresponding to the thickness of the wall. A pair of side flanges have engagement features configured to attach to the connection ribs of the top panel after adjusting the width of the top panel, to assemble the capping system. A wave diverter and/or structural reinforcement system can optionally be provided with the convertible capping system or sheet piling wall.
