A composite floor structure and method of making the same are disclosed. The composite floor structure may include a platform and a plurality of transverse beams. The composite floor structure may also include at least one longitudinal beam and a plurality of insert beams to accommodate the longitudinal beam. The composite floor structure may also include an underlayment between the plurality of transverse beams and the at least one longitudinal beam. Some or all of these components may be integrally molded together to form a fiber-reinforced polymer structure. The composite floor structure may be used for cargo vehicles and other applications.

Seawalls and methods for making seawalls are disclosed. A seawall may include a concrete footing, with a first plurality of anchorages disposed in the concrete footing. A plurality of precast concrete tee beams may include single-tee beams and/or double-tee beams. Flanges of the tee beams may be positioned to form seaward and landward faces of the wall, and stems of the tee beams may be coupled to the footing between the seaward and landward faces. A second plurality of anchorages may be disposed at tops of the stems. Elongate steel components extend through the stems, and are tensioned between the first plurality of anchorages and the second plurality of anchorages. Interior fill may be disposed between the seaward and landward faces. One or more wave deflectors may be disposed above the tee beams.

Disclosed are a cement coating for inducing the settlement of marine sessile organisms and an application technology therefor, and, in particular, a construction method for an ecological riprap breakwater, an induced cement-based coating, and a preparation method thereof. The cement coating for inducing the settlement of marine sessile organisms is coated on surfaces of rocks, and a reasonable spatial layout is applied, such that each rock pile (block) can effectively break waves and ensure smooth exchange between water bodies on two sides. After oysters attached to each rock pile (block) breed a large amount, the water bodies can be purified, and the ecological environment in the surrounding sea area can be improved.

A floating dock hinging latch releasably interconnects a pair of floating dock sections in an adjoined spaced relation for relative hinging motion. The floating dock hinging latch includes a pair of female latch portions secured to the side of one floating dock section and a pair of male latch portions secured to the side of the other floating dock section. The female latch portions and male latch portions are releasably engaged with one another to hingedly connect the floating dock sections by moving the floating dock sections toward one another across the surface of the water.

An installation for the in-port storage of liquid fuel, which is formed near a dock, is formed of at least an upper surface substantially parallel to the free surface of the sea and a frontal surface adjacent to the upper surface and partially immersed. The installation includes at least one module having a floating caisson containing a fluidtight tank that may contain liquid fuel and having a closed contour formed of an upper face, a lower face, and several lateral faces. The module is fixed to the dock by anchoring means connecting one of the lateral faces of the caisson to the frontal surface of the dock, the lower face and the lateral faces of the caisson therefore being at least partially immersed.

The disclosed systems, methods, and apparatuses may combat coastal erosion using a shell module shaped to enable retention of sand on a beach and shore face. The shell module may be shaped to minimizing interference with recreational use of the beach and providing a beneficial environment for desirable sea life. The modular shell can be conveniently transported and emplaced in shell reefs. These shell reefs may comprise multiple, optionally interlocking shell modules. These shell reefs can prevent fill, such as sand, de-watered sand, or sand slurry from being scoured and sluiced out to sea. The disclosed systems and methods harness the energy of incoming and returning waves, including tidal and surf action, to assist in spreading the fill, recreating a natural beach, complete with layers of sand capable of resisting the scouring force of ocean waves and currents.

The present invention relates to a removable artificial reef and barrier system capable of mitigating detrimental wave and current energy and erosion problems, enhancing biological growth and marine aquaculture, increasing carbon sequestration, providing power generation, and enhancing favorable surf conditions for recreational use.
