Definitions

• This invention relates to natural deep-water ports located offshore and methods for their construction and more particularly to modular construction of deep-water ports that contain a breakwater as an integral component of the port.
• a second obstacle is the lack of sufficiently deep water near the coast and the massive expense that additional dredging and construction of retaining walls entails. For example, between 2000 and 2005, the Kill van KuIl channel (New York/New Jersey) was deepened from 35 feet to 45 feet at a cost of $360 million, and the project currently underway to dredge the channel to the 50 foot depth required for 7000 - 8000 TEU capacity ships will add more than $900 million to the overall cost.
• U.S. Pat. No. 6,234,714 discloses a pier with a nominally integrated breakwater.
• the breakwater and pier are in fact independent structures, in which the breakwater comprises a mound of sand, gravel, rocks, and/or rubble piled up against the seaward side of the pier, upon which a plurality of caisson-like structures are placed.
• this design also suffers from the problems that the breakwater cannot be constructed without extensive dredging operations and that the breakwater and the pier are not a single modular structure.
• the present invention provides a solution to the problems described above and an answer to the need for a new way of thinking about port design. It is one object of the present invention to provide an offshore deepwater port in which the pier deck and breakwater are integrated into a single structure, with the former forming an upper deck and the latter a constructive truss beneath, in which the port structure is built in deep water as an independent unit.

• the six planar surfaces left from the faces of the original cube e.g. surface 14, remaining from side EFGH) are base planes by which the perforated modular marine structure contacts other modules. These surfaces must be large enough to ensure stable positioning of the module on a substantially horizontal foundation during the assembly process.
• the perforated modular marine structures are formed with reinforcing diagonal beams (RDBs) 30 extending along the six diagonals on the planar surfaces remaining from the faces of the original cube.
• the RDBs may comprise reinforcing elements, for example, steel rods 32, and material embedding the reinforcing elements, e.g. concrete.
• Recesses 42 are formed on the cube's surface at the corners of the module. When two to eight modular marine structure units 10 are arranged about a common corner, these recesses form cavities that serve as a mold for casting concrete or injecting grout to create corner joints. Similar recesses 52 may be formed along the diagonals, as shown in FIG. 1.

• an integrated deepwater offshore port 100 which comprises an upper pier deck 1 and an under-deck 2.
• the upper pier deck is constructed of materials appropriate for use in salt water. It is designed for mooring of mega-ships, as a base for heavy cranes and other equipment used for on-loading and off-loading of cargo to and from the ships, and as a temporary location for cargo to be loaded onto the container ships or to be transferred to the container terminal.
• the embodiment shown in FIGS. 6 and 7 shows the upper deck as having a rectangular profile, but due to the modular nature of the port's construction, the exact dimensions and shape of the upper deck will necessarily vary from embodiment to embodiment according to the specific needs of the port itself. Similarly, the exact dimensions and shape of the under-deck will be chosen in order to provide support for the upper deck, and will thus vary depending on the needs of the specific port being constructed.
• the under-deck 2 is constructed from a plurality of perforated modular marine structure units 10.
• the perforated modular marine structure units are prefabricated and designed such that they are capable of interconnection, and are constructed from material that is compatible with long-term immersion in salt water.
• FIG. 1 One embodiment of said perforated modular marine structure unit is presented in FIG. 1.
• This embodiment illustrates the essential qualities of the unit, in particular, its modularity (i.e. construction of the under-deck 2 is done by interconnecting a plurality of identical elements as illustrated in FIG. 5), its interconnectability, and its ability to allow water to pass through it. In this particular embodiment, water flows through cut out portions of the structure.
• the unit may contain passages or be itself constructed from smaller sub-units in order to allow passage of water.
• the embodiment shown in FIG. 2 is provided to illustrate the construction of the integrated dock, and is not intended to limit its construction to use of the specific embodiment shown in the figure.
• the under-deck sits directly on the natural sea floor and is constructed from prefabricated modular marine units 10 which are constructed on-shore, and the upper deck sits atop the mega- structure.
• the elements are interconnected (cf. FIG. 5) in dry dock. After the modular marine units are interconnected, a platform of at least one level is built. It is possible to build further structures atop the platform, with the platform itself serving as a foundation for the structures. After the work is completed in dry dock, the dry dock is filled with water to float the platform and everything on top of it. The platform is then towed (afloat) to its ultimate location in deep water, at which point water is allowed to enter the cavities within the modular marine units, causing them to sink to the sea floor, thus creating the breakwater port.
• the elements may be interconnected in wet dock and the port then towed to its ultimate location.
• the under-deck is constructed from perforated units, it acts naturally as an efficient breakwater, providing still water on its landward side, and thus enabling the upper deck to act as a pier or wharf for cargo ships without the need for construction of a separate dedicated breakwater.
• the perforated units additionally can serve as a habitat for underwater flora and fauna, and hence, the under-deck as constructed can also serve as the basis of a man-made reef.
