Detailed Description
The present invention relates to a modular structure for a floating infrastructure. In particular, the present invention relates to modular structures that allow expanding floating infrastructures to increase habitable space on earth to address sea level rises due to climate change.
It is envisaged that the sea level of this century may rise by 0.63m and that the global ocean surface temperature may increase by 1 to 4 ℃ due to climate change and global warming, causing damage to coastal cities and coastal ocean biodiversity. Thus, according to embodiments of the present disclosure, the modular structure for building floating infrastructure of the present invention provides an alternative flexible and sustainable land resource built with low/zero carbon sustainable materials. The modular structure used to construct the floating infrastructure can be used to house intelligent and energy efficient buildings, generating electricity from renewable energy sources. Furthermore, because the modular structure is modular in nature, the floating infrastructure has enhanced scalability and adaptability, which enables it to be deployed globally. Taking up marine space for the floating infrastructure may interfere with existing vessel airlines and anchor locations, and the modularity of the floating infrastructure ensures that the marine space reserved for the floating infrastructure is fully utilized.
Unlike designs for offshore floating structures, such as semi-submersible where the primary function is to camp on the sea for oil well drilling operations, designs of floating infrastructure for residential, work, recreational purposes require more intensive investigation of human comfort.
Floating infrastructure is an alternative sustainable approach that can cope with the effects of sea level rises and create new habitats and living spaces both above and below water.
Furthermore, even if the environmental conditions are different compared to land-based fixed facilities, the comfort of the floating platform occupants should not be compromised.
The floating infrastructure also includes the following green features to facilitate sustainability:
Green concrete such as carbon cured concrete, concrete with Recycled Concrete Aggregate (RCA) or even concrete with cement replacement techniques. These techniques help reduce carbon output by utilizing the emitted carbon dioxide to cure the cement or convert it into fuel and other beneficial products. Cement replacement technology enables concrete to be produced without the need for portland cement, but instead alternatives (such as steel slag, i.e., waste material from a steel mill) can be used to bond the concrete.
-Mounting solar panels on a roof of a superstructure
-Collecting rainwater and treatment facilities on the roof of the superstructure

Fig. 1 shows a floating infrastructure 100 according to an embodiment of the invention. Fig. 2 shows a top view of floating infrastructure 100 according to an embodiment of the invention. As shown in fig. 2 and 3, modular structure 200 is used to build floating infrastructure 100. Additional details regarding modular structure 200 will be described below.
Fig. 3 shows a cross-sectional view of a first embodiment 110 of a floating infrastructure according to an embodiment of the present disclosure. Thus, the first embodiment is a 2-layer single-shell modular structure 300, wherein dolphins are used to anchor the modular structure 300 to the seabed. The space within the housing may be used for ballast tanks, basement living components, infrastructure systems, planting rooms, water tanks, and the like. Those skilled in the art will recognize that the number of layers within the housing depends on the depth of the housing and is left to those skilled in the art as a design choice.
Fig. 4 shows a cross-sectional view of a second embodiment 120 of a floating infrastructure according to an embodiment of the present disclosure. In a second embodiment, multiple floors of modular structure 400 are built with the bottom floor disposed on the seabed. Similar to the 2-tier single-shell modular structure 300, the space within the shell of the multi-floor modular structure 400 may be used for ballast tanks, basement living components, infrastructure systems, planting rooms, water tanks, and the like. Those skilled in the art will recognize that the number of layers within the housing depends on the depth of the housing and is left to those skilled in the art as a design choice.
Based on fig. 3 and 4, one of ordinary skill in the art will recognize that each modular structure 200 includes at least one floor. Fig. 5 illustrates a partial cross-sectional view of a modular structure 200 according to an embodiment of the present disclosure. Modular structure 200 includes a bottom housing 210 and a top housing 220. Although top shell 220 shows one layer similar to 2-layer single-shell modular structure 300, top shell 220 may be split to form multiple layers similar to multi-floor modular structure 400. In short, those skilled in the art will recognize that the number of layers within the housing depends on the depth of the housing and is left to those skilled in the art as a matter of design choice.
Fig. 6 shows an exploded view of modular structure 200. Modular structure 200 includes foundation slab 710, foundation cell form 720, basement slab 730, outer bulkhead 740, column 750, honeycomb double wall 760, and platform deck 770. The bottom housing 210 is defined between the foundation plate 710 and the basement plate 730, while the top housing 220 is defined between the basement plate 730 and the platform deck 770.
The base unit form 720 is disposed between the base plate 710 and the basement plate 730, thereby forming the bottom case 210. The base unit form 720 is configured with a honeycomb configuration to provide rigidity and redundancy.
An outer bulkhead 740 extends from the perimeter of the base plate 710 to the platform deck 770. The outer bulkhead 740 is a side wall of the modular structure 200 and defines the height of the modular structure 200. The outer bulkhead 740, basement plate 730 and platform deck 770 define an interior space that forms the top shell 220. The interior space may be a single floor, as shown by the 2-tier single-housing modular structure 300 in fig. 3, or may be further divided into a plurality of basement floors, as shown by the multi-floor modular structure 400 in fig. 4. Those skilled in the art will recognize that the number of floors within the top housing depends on the depth of the housing and is left to those skilled in the art as a design choice.
A honeycomb double wall 760 is provided along the inner surface of the outer bulkhead 740. The honeycomb double wall 760 acts as a ballast system. Fig. 7 shows a ballast system 780 comprising a ballast water pump control system 1, a ballast water pipe 2 and a ballast tank 3 housed in a honeycomb double wall 760. Ballast water pump control system 1 may reside within top housing 220 to rapidly distribute water to associated ballast tanks 3 via ballast water lines 2 to distribute weight to maintain inclination and comfort.
Columns 750 are provided and extend from the foundation plate 710 to the platform deck 770.
As shown in fig. 6, the columns 750 in the bottom housing 210 and the top housing 220 are evenly distributed within the perimeter of the modular structure 200. However, in another embodiment as shown in fig. 5, the pillars 750 in the top housing 220 may be unevenly distributed. Specifically, as a means of economical design, the columns 750 in the bottom housing 210 are evenly spaced to evenly distribute building loads to the columns 750 and base unit forms 720 in the bottom housing 220. In this case, the bottom housing 210 allows adjacent cells in the base cell form 720 to share and disperse uneven loads transferred from the columns in the top housing 220 supporting the building. This means that there is some room to displace the posts 750 in the top shell 220 so that the posts 750 in the top shell 220 do not need to be evenly spaced, which allows flexibility in the space planning of basement floors and upper floors.
The honeycomb double wall 760 includes ballast tanks 3 for controlling the buoyancy of the modular structure 200. An active compensation ballast system 780 may be installed to constantly monitor the draft and inclination of the modular structure 200 and perform sufficient ballasting to hold the modular structure 200 to a specified draft and stand upright. In some embodiments, if the live load (moving load from a person, vehicle, etc.) is relatively small compared to the overall module, an active ballasting system may not be needed, as the movement will not cause too much change in the draft/tilt of the modular structure 200. In this embodiment, a ballast system 780 would be provided to allow for transportation of the modular device 200 and future repositioning possibilities. The size of the bottom hull depends on the amount of ballast tanks needed to control the buoyancy of the modular structure 200 and to carry the load of the top hull and the structure above the top hull, and this leaves one of skill in the art as a design choice.
As shown in fig. 6, the modular structure 200 is hexagonal in shape. Each modular structure 200 may be adjacently coupled together by flexible coupling arms to form a cluster. As shown in fig. 1 and 2, three modular structures 200 are coupled together to form a cluster. Modular structure 200 may be connected together via rigid or flexible connectors. The rigid connectors essentially connect the 2 modular structures 200 together to form a cluster. The flexible connector allows the modular structure 200 to retain a certain individuality and allows the draft to vary without interfering with each other. Flexible linkage arms are examples of flexible connectors. The flexible linkage arms can be easily installed and removed, keep the modular structures fixed at safe distances from each other, and also couple the motion of each floating platform in the cluster. When more modular structures 200 are coupled together to form a large cluster of floating infrastructures, the total mass of the floating infrastructures will increase, inevitably increasing the stability of the floating infrastructures, making the floating infrastructures less susceptible to wave and tidal changes.
To reduce greenhouse gas emissions, the modular structure 200 is manufactured using advanced concrete techniques that absorb carbon dioxide for curing or replace cement with alternative materials such as slag, silica binders, and concrete with Recycled Concrete Aggregate (RCA).
Each modular structure 200 is hexagonal in shape with an area of about 5,000 square meters (sqm) that can be joined and connected together to form clusters of 3, 6, and 9 or more to form floating cities. The engagement of the modular structure can be easily accomplished with a hexagonal shape. The modular units require shorter lead times and this allows the floating city requirements to be met more efficiently. A single platform has an area of 5,000sqm, which can accommodate approximately 2000 occupants, and 3 modular structures 200 can accommodate up to 6000 occupants when connected together. These numbers may vary depending on how the superstructure is designed, whether they are used more for apartments, offices, or other entertainment purposes.
Modular floating infrastructures can be extended and redeployed to locations with different environmental conditions around the world to address climate change issues. The design of the modular structure is hexagonal in shape. The hexagonal shaped modular structure is symmetrical from all sides and will result in providing optimal stability and ease of construction. This is the best shape in terms of modularity and stability, but various combinations are possible.
The above is a description of an exemplary embodiment of a modular floating infrastructure according to the present invention. It is anticipated that one skilled in the art can and will design alternative infrastructures, devices, systems and methods that do not violate the present invention, based on the present disclosure, as set forth in the appended claims.
