Description

Technical Field

[0001] The invention relates to the field of marine floating bodies, and in particular to a giant closed floating ship. Background Art

[0002] With the acceleration of global economic integration and the continuous deepening of marine development, human demand for marine activity space has shown explosive growth, so the development and utilization of marine space and the construction of marine cities have become the focus of attention of countries around the world. At present, offshore buildings mainly include traditional cargo ships, offshore platforms, large cruise ships and floating buildings. Among them, although traditional ships are constantly developing in tonnage and scale, their functions are still relatively single; although offshore platforms have good stability, they have poor maneuverability and extremely high construction and maintenance costs; although large cruise ships have certain living and entertainment functions, they are limited by the hull structure and cannot realize real urban functions; floating buildings are mostly near-shore fixed structures with small scale and limited application scenarios.

[0003] In the current marine engineering field, traditional floating structures face serious technical bottlenecks in the process of large-scale development. The primary problem is the contradiction between structural strength and weight. Traditional steel structure construction not only consumes a large amount of steel, resulting in high costs, but also has low material utilization, making it difficult to achieve lightweight design. The second is the safety issue. Existing offshore buildings mostly use an integral hull structure with limited wind and wave resistance, and once damaged, it is easy to cause the entire structure to sink. At the same time, energy supply relies on fossil fuels, which not only has poor environmental performance, but also lacks sustainable clean energy solutions. In addition, the low efficiency, high labor costs and limited modularity of traditional shipbuilding technology also seriously restrict the construction of ultra-large offshore buildings.

[0004] Although there are some innovative large-scale floating platform design solutions, these solutions generally have problems such as high construction costs, complex structural systems, difficult construction, and high energy consumption. Especially in the design of floating structures, traditional solid steel structures are neither economical nor environmentally friendly, and existing lightweight solutions are often insufficient in strength or too expensive. At the same time, the single functional layout cannot meet the future offshore city's demand for multifunctional composite use such as residence, commerce, and logistics. In terms of maintenance and operation, high maintenance costs, difficulties in equipment renewal and transformation, and complex operation management have also become important factors restricting development.

[0005] In the face of these technical challenges, a breakthrough solution is urgently needed that can ensure structural strength and safety while achieving lightweight and economic efficiency; it must have the characteristics of modularization and standardization while meeting the needs of multifunctional composite use; and it must also make breakthroughs in energy conservation and environmental protection to achieve sustainable development. The construction of this new type of mobile sea city will provide new possibilities for human development and utilization of ocean space. Summary of the invention

[0006] The technical problem to be solved by the present invention is: to provide a lightweight, highly safe, multifunctional integrated enclosed floating giant ship in view of the technical problems of existing offshore buildings such as heavy structural weight, poor safety, single function, high energy consumption and low construction efficiency.

[0016] Preferably, the truss support structure is composed of columns, diagonal braces and upper beams, and the columns and diagonal braces are connected through rib plates and support seats.

[0017] Preferably, the multiple closed floating bodies are connected by concealed bolts.

[0018] The beneficial effects that can be achieved by the present invention are:

[0019] 1. The hull structure is composed of multiple closed buoys, which makes the hull have excellent anti-sinking performance. Even if some closed buoys are damaged, the other buoys can still remain intact, avoiding the safety hazard of the traditional integral hull that is easy to sink as a whole. Concealed bolts are used to connect the multiple closed buoys, which not only ensures the integrity of the structure, but also facilitates maintenance and replacement.

[0020] 2. The present invention adopts a truss support structure in conjunction with a closed floating body design. Through the reasonable arrangement of columns, diagonal braces and upper beams, while ensuring the overall strength, the structural weight is greatly reduced, the material utilization efficiency is improved, and the construction cost is reduced.

[0021] 3. By towing multiple wind turbines at the stern of the ship and installing wind turbines on the truss support structure, a multi-level clean energy supply system is formed, which significantly reduces dependence on traditional fossil energy and improves environmental protection performance.

[0022] 4. The modular cabin design is adopted, and through the reasonable arrangement of multiple functional areas, it meets the diverse needs of residence, commerce, logistics, etc. The living building and supporting public facilities system set up in the cabin provide residents with complete living facilities and realize the real function of a sea city.

[0023] 5. The cabin frame structure assembly method is adopted, including the standardized design of the side cabin frame, standard cabin frame, middle cabin frame and cabin beam, which significantly improves the construction efficiency, reduces the construction difficulty, and provides convenient conditions for later expansion and renovation.

[0024] 6. Through the scientific arrangement of multiple closed floating bodies and the rigidity reinforcement of the truss support structure, the overall structure has good wind and wave resistance, which improves the stability of sea navigation. Through standardized connection methods and modular design, the giant ship has good scalability and can flexibly increase or decrease functional modules according to actual needs to adapt to changes in demand in different usage scenarios.

[0056] The present invention is further described below in conjunction with the accompanying drawings and examples, but these specific implementation schemes do not limit the protection scope of the present invention in any way.

[0057] Example 1

[0058] like Figure 1-16 As shown, the present invention discloses a giant closed floating ship, including a hull 1 composed of a plurality of box-type closed floating bodies, a truss support structure 2 and a functional cabin 3 arranged on the hull 1. The mobile city at sea adopts a modular design, and the total length of the box-type closed floating body is 3162m and the cross-sectional width is 192m. The giant ship is mainly composed of about 1500 closed floating bodies to form a basic load-bearing structure, a truss support structure 2 is arranged on the floating body to form a support system, and an aircraft runway 4 and a helipad 5 are arranged on the truss support structure 2.

[0059] In the present invention, about 1500 closed floating bodies are used to form the basic load-bearing structure, which can realize standardized production, greatly reduce manufacturing costs, facilitate segmented construction and assembly, improve construction efficiency and shorten construction period, facilitate repair and replacement, reduce maintenance costs, and the partition design improves safety. Even if part of it is damaged, it will not cause the entire body to sink, truly realizing an "unsinkable" carrier.

[0060] In this embodiment, the box-type closed floating body is composed of a core plate, which includes a panel, a sandwich layer, and a panel. The sandwich layer is preferably designed as a core tube array, that is, it includes a number of core tubes arranged at intervals, and the upper and lower ends of the core tubes are flanged and brazed to the panels. The "panel-sandwich layer-panel" sandwich structure is adopted, and the sandwich layer adopts a core tube array design, which significantly improves the structural strength, reduces the weight, improves the material utilization rate, saves materials, and has good compression resistance and fatigue resistance, which can make the overall structure of the floating body stable and evenly stressed.

[0061] It is further explained that the arrangement of the core tubes can be an equilateral triangle, a square, a trapezoid or a polygon. The core tubes can be closely arranged or spaced, and small holes are provided on the upper and lower parts of the core tubes. The purpose of setting these small holes is to enable the core tubes to be filled with thermal insulation materials, especially foaming materials. The small holes are arranged in the upper and lower parts because the filling of thermal insulation materials is carried out after the core materials are connected and formed, and the small holes on the core tubes in the middle part will be blocked by the surrounding core tubes. In this embodiment, the flanging design of the core tube increases the connection strength and improves the structural reliability. The flexible arrangement method can also be optimized according to different force requirements. The filling of thermal insulation materials improves the thermal insulation performance of the float, optimizes the construction process, and solves the problem of filling the middle core tube. Finally, the core tube and core plate in this embodiment are made of corrosion-resistant materials, such as titanium steel, stainless steel, fiberglass, carbon fiber or pure titanium, which can improve the corrosion resistance and service life of the overall structure.

[0062] In this embodiment, there are multiple groups of truss support structures 2, each group of truss support structures 2 is composed of main columns 201, diagonal braces 202 and upper beams 203, and the total weight of the truss support structure 2 is 42,500 tons. Among them, the main columns 201 adopt the specifications of Φ2020×22, and the distance between the columns of two adjacent groups of trusses is 72m; the diagonal braces 202 adopt the specifications of Φ1020×12, and there are four diagonal braces 202 connected to both sides of the columns in the truss support structure 2. The four diagonal braces 202 and the columns form cross supports, providing better lateral stability; the upper beam 203 adopts the specifications of Φ3400×43, and the upper beam 203 is a circular steel pipe structure, and a connecting beam 204 connected to the upper beam 203 of another group of truss support structures 2 is extended on one horizontal side, and the connecting beam 204 adopts the specifications of Φ1020×12. The truss support structure 2 is connected by standardized nodes, and the main column 201, the diagonal brace 202 and the upper beam 203 are reliably connected by M30 high-strength bolts. The main column 201 and the diagonal brace 202 on both sides are fixedly connected in an * shape at the intersection. More specifically, the main column 201 adopts a circular steel pipe of φ2020×22, and the diagonal brace 202 adopts a circular steel pipe of φ1020×12. The column and the diagonal brace 202 are connected by rib plates 205 on both sides. The thickness of the rib plate 205 is 12mm, and the maximum distance between the internal bending point of the rib plate 205 and the diagonal brace 202 is 300mm. The design of the rib plate 205 avoids stress concentration, improves the bearing capacity of the node, prolongs the service life of the component, and also improves the fatigue resistance of the structure. In addition, inner ring ribs 206 are provided at the connection nodes, and the rib plates 205 are welded to the inner ring ribs 206. The specifications of the inner ring ribs 206 are φ1976×1376×16. The inner ring ribs 206 are designed to enhance local strength and improve the overall stability of the structure.

[0063] The truss support structure 2 of the present invention is a multi-group combined structure composed of main columns 201, diagonal braces 202 and upper beams 203. The combined structure forms a stable spatial force system with a reasonable structural weight (42,500 tons). While achieving lightweight design, it provides good bearing capacity and structural stability. In addition, the modular design facilitates construction and maintenance.

[0064] In this embodiment, a runway 4 with a length of 3217m and a width of 72m is set on the top of the truss. The height from the reference plane of the runway 4 to the bottom of the hull 1 (box-type closed floating body) is 103.5m in total. Guardrails 401 with a height of about 1270mm are also set on both sides of the runway. Specifically, the runway 4 is set above the upper beam 203. The surface of the runway 4 adopts H8-level runway plate with a thickness of 266mm, which can meet the take-off and landing requirements of heavy passenger aircraft and has excellent bearing capacity. According to actual tests, the runway can accommodate a 747-type flying passenger aircraft to pass through completely. In addition, guardrails 401 with a height of 1.27m are also set on both sides of the runway. The guardrails 401 adopt a special anti-collision design to prevent the aircraft from deviating from the runway, reduce the risk of accidents, and enhance the protection capability in emergency situations. The runway surface is also equipped with a complete drainage system to ensure that the aircraft can take off and land safely on rainy days, prevent water accumulation from affecting the friction coefficient of the runway, and improve the all-weather operation capability. The runway lighting system includes runway edge lights, runway end lights and approach lighting systems, which improve the safety of nighttime takeoff and landing, provide clear visual guidance, and meet the needs of all-weather operation. The total length of the entire runway 4 is 3217m, and one side of the runway 4 exceeds the total length of 3162m by a total of 56m.

[0065] In this embodiment, a circular apron 501 and a rectangular apron 502 are respectively arranged at both ends of the runway. The circular apron 501 has a diameter of 180m and can accommodate at least 4 747 aircraft. Two main beams 7 are arranged in the center of the circular apron 501. The distance between the two main beams 7 is 36m. The distance between the first circular apron beam A8 and the main beam 7 is 31m, and the distance between the second circular apron beam B9 and the first circular apron beam A8 is 27m. The distance between the first circular apron beam C10 and the second circular apron beam C10, and the distance between the second circular apron beam C10 and the third circular apron beam C10, which are arranged vertically to the main beam 7, is 48m. In addition, a plurality of H8 runway beams 6 are arranged at the bottom of the apron 5. Each runway is 2000mm high and 266mm wide. The distance between the runway beams 6 is 4000mm. The circular apron 501 adopts an innovative beam arrangement to form a scientific and reasonable force system, which can provide better structural stability, optimize the bearing capacity distribution, reduce structural deformation, improve overall stiffness, and extend the overall service life of the circular apron 501.

[0066] The rectangular apron 502 is 180m wide and 200m long, and can accommodate at least 7 747 aircraft. An apron upper beam 11 is provided in the middle of the rectangular apron 502. A plurality of parallel square apron beams A12 and a plurality of vertical square apron beams B13 are provided on both sides of the apron upper beam 11. The spacing between the square apron beams A12 is 36m; the spacing between the square apron beams B13 provided in the vertical direction to the apron upper beam 11 is 48m; the plurality of square apron beams A12 and square apron beams B13 form a grid support structure, which optimizes the load transfer path, reduces structural deformation, and improves the torsion resistance of the rectangular apron 502. The apron upper beam 11 adopts a Φ3400×43 round tube structure, and a plurality of beam upper web members 14 are provided between the two apron upper beams 11. The beam upper web members 14 adopt a Φ820×12 round tube, which improves the torsion resistance of the structure and increases the fatigue life of the structure. In addition, a plurality of H8 runway beams 6 are provided at the bottom of the apron 5. Each runway beam is 2000mm high and 266mm wide. The distance between the runway beams 6 is 4000mm, which is used to strengthen the integrity of the structure and provide sufficient bearing capacity. The entire runway 4 and apron has a total area of ​​267,000 m2 and a total weight of 62,800 tons.

[0067] In this embodiment, the tail of the hull 1 also tows two sets of wind turbines 15, which are arranged on the left and right sides of one end of the hull 1. From a high-altitude bird's-eye view, the wind turbines 15 at the tail of the hull 1 are arranged in a double-wing symmetrical manner, so that the overall structure has good directional stability. Each set of wind turbines 15 includes 8 wind turbines, each wind turbine is 8MW, and the total is 128MWh. In addition, the 16 wind turbines are also connected to a 400MW battery (not shown in the figure) through cables. The wind turbines and batteries jointly supply the overall facility power of the giant ship, including the power of 6 8MW electric propellers (2 are arranged at the front end of the hull 1). The ship's rated speed can reach 10 knots and the maximum speed can reach 12 knots.

[0068] In this embodiment, the cabin system is arranged above the box buoy, and adopts a layered design with two layers. The bottom cabin is used as a cargo storage area 17, and a standardized cargo passage is set. A hatch for transporting cargo is set on one side of the inside of the bottom cabin. A crane 18 for conveying materials is also installed in the cabin. A crane track 19 is set on the upper part of the cabin, and the crane 18 is installed on the crane track 19 for movement. The bottom cabin is about 12m high. Specifically, the crane system of the cabin includes a fixed crane and a mobile crane. The fixed crane is installed at a specific location for loading and unloading large cargo; the mobile crane 18 is installed on the crane track 19, and the control system of the crane 18 adopts an intelligent design to realize automatic operation. The upper layer is the equipment control layer, and various pipeline systems are set, including power supply, communication, water supply and drainage pipelines, etc., to facilitate maintenance and replacement.

[0069] The upper part of the cabin system is for commercial and residential use. In this embodiment, multiple living buildings 20 are arranged above the floating body and in the middle of the cabin. Specifically, there are 76 living buildings 20 with 30 floors, of which 8 floors are arranged in the middle of the cabin, with a total area of ​​1.29 million m 3 There are 22 floors above the floating deck, with a total area of ​​950,000 m 3 , which can accommodate 13,300 households. Each living building is equipped with complete water supply, drainage and power supply systems to facilitate the daily life needs of residents.

[0070] When working, the mobile city at sea provides basic buoyancy through about 1,500 independent closed floats, and maintains overall balance through a distributed buoyancy control system. Each system works together: cargo is loaded and unloaded through an automated crane 18 system; personnel are managed through an intelligent channel system; equipment is maintained using a modular replacement mechanism; and the security monitoring system operates 24 hours a day to ensure overall safety.

[0071] The cabin system design disclosed in the present invention adopts a two-layer structure. Through the reasonable layout of the bottom cargo storage area 17 and the upper equipment control layer, the limitations of traditional offshore buildings in terms of space utilization and functional zoning are solved. An intelligent crane system combining fixed and mobile types is innovatively designed, equipped with an intelligent control device, which effectively solves the problems of low efficiency and high labor cost of marine cargo transportation. By setting up integrated power supply, communication, water supply and drainage pipeline systems on the upper layer, the technical problems of difficult maintenance and inconvenient replacement of offshore construction equipment are solved. The organic combination of the cabin system and the upper 76 active buildings 20, combined with the distributed buoyancy control provided by 1,500 independent closed floats, successfully solves the problems of poor stability and insufficient carrying capacity of offshore buildings. At the same time, the modular design concept and intelligent management system are adopted to realize the automation and intelligence of cargo loading and unloading, personnel management, and equipment maintenance, effectively improving the overall operational efficiency and safety performance of the mobile city at sea, and providing reliable technical support for the sustainable development of the offshore city.

[0072] On the other hand, the present invention solves the technical problems of traditional offshore buildings such as heavy weight, poor safety, single function and high energy consumption through innovative structural design. By using flanged core material to make a closed pontoon 25, the structural weight is significantly reduced while ensuring strength, and 70% of steel can be saved compared to traditional steel structures. The partition design composed of about 1,500 independent floats can ensure that the hull 1 will not sink as a whole even in the event of an accident. The use of modular design and automated production technology can save 95% of labor costs. Through reasonable layout, multifunctional comprehensive utilization such as cargo transportation, population residence, tourism, and commercial trade is realized, and it can accommodate 70,000 people to work and live.

[0073] In this embodiment, the cabin is assembled from multiple sets of cabin frame structures (refer to Fig. 22 ), the cabin frame structure includes a side cabin frame 21, a standard cabin frame 22, a middle cabin frame 23 and a cabin beam 24, wherein the side cabin frame 21 is arranged at the outer edge as the peripheral support of the overall structure; the standard cabin frame 22 and the middle cabin frame 23 are arranged in parallel along the length direction of the box-type closed floating body, and the standard cabin frame 22 is located between the side cabin frame 21 and the middle cabin frame 23. The cabin beam 24 is vertically connected between adjacent cabin frames to form a lateral support. Structural columns are arranged at the intersections of the side cabin frame 21, the standard cabin frame 22, the middle cabin frame 23 and the cabin beam 24 to further enhance the node connection strength.

[0074] For further information, see Figure 13-14 , the connection of each closed pontoon 25 adopts a standardized interface design. Specifically, the outer edge of the pontoon 25 is designed with a reinforcing rib plate 205, and the two pontoons 25 are connected by connecting M30 bolts 2603 and the belly holes (35.5×30.5) on the reinforcing rib plate 205. The inner side of the pontoon 25 is connected by an inclined concealed bolt 26, which specifically includes an inclined waist sleeve 2601, a Φ63x5 M30 blind hole internal threaded round sleeve 2602 and an M30 bolt 2603 to ensure the structural strength of the connection. Sealing strips are set at the joints between the pontoons 25 to prevent seawater from seeping in.

[0075] The giant ship of this embodiment has a rated displacement of up to 2.1 million tons, a maximum displacement of up to 2.93 million tons, a rated commercial load of up to 1 million tons, a rated draft of 3.63m, and a maximum draft of 6.6m. Through modular and intelligent design concepts, the comfort and safety of the marine living environment are unified, providing personnel with a good working and living space, lightweight and high-strength composite materials reduce the overall weight, triple redundant intelligent control systems improve operational reliability, and modular environmental control achieves the unity of comfort and safety.

[0076] Example 2

[0077] like Figure 17-21As shown, the difference between this embodiment and embodiment 1 is that, in this embodiment, the tail of the hull 1 does not tow the wind turbine generator set 15, but four 4MW wind turbines are arranged in the middle of the truss support structure 2, a total of 16MW wind turbines, and the 16MW wind turbines are connected to a 72MWh battery pack through a transmission cable. The wind turbine includes a wind turbine 1501 and a tower 1502. The outer diameter of the wind rotor of each wind turbine 1501 is 112m, the distance between two adjacent wind turbines is 115m, the distance from the wind turbine 1501 of the wind turbine to the top surface of the box-type closed floating body is 78.041m, when the wind turbine is laid down, the distance from the top of the wind turbine 1501 to the top surface of the box-type closed floating body is 44.932m, and the thickness of the box-type closed floating body is 4532mm. The tower body 1502 includes an upper tower body and a lower tower body. The upper tower body and the lower tower body include tower columns, connecting columns connecting the tower columns, and struts obliquely arranged between the tower columns and the connecting columns. The size of the tower columns is Φ720X25, the size of the connecting columns is Φ273X12, the size of the struts is Φ159X10, and the distance between the two tower columns at the lowest end of the lower tower body 1502 is 7992mm. The upper tower body and the lower tower body are detachable, and further, the two are rotatably connected by a rotating shaft. Since the upper tower body can rotate around the lower tower body, the upper tower body can be laid down in stormy weather or when the wind turbine needs to be disassembled and repaired or when entering an inland river. In order to better support the laid-down upper tower body, four corresponding stiffening mechanisms 16 are provided on the top of the cabin. The stiffening mechanism 16 is a triangular steel frame structure, the bottom of which is fixed to the top of the cabin by bolts or welding, and the top is used to carry the laid-down wind turbine 1501.

[0078] In addition, in order to strengthen the stability of the wind turbine 1501, a handrail 30 for fixing and auxiliary supporting the lower tower body is installed around the lower tower body on the cabin top.

[0079] The enclosed floating giant ship of this embodiment has an overall length, width and height of 366mX51.25mX24m (including the wind turbine, the overall height can reach 139m, and if the wind turbine is laid down, it can reach 45m). The front end of the hull 1 is a triangular structure and the rear end is a rectangular structure. A ship building 27 is erected on the front end of the hull 1. The triangular structure is 78m long and 51.25m wide. The entire hull 1 weighs 10,000 tons.

[0080] The truss support structure 2 in this embodiment is also different from the truss support structure 2 in Example 1. The truss support structure 2 in this embodiment is composed of multiple web members and upper beams 203 arranged on the web members to form multiple continuous triangular structures or multiple sawtooth structures. The size of the upper beam 203 at the top is Φ820X43, the web members are Φ377X12, each web member is about 12190mm long, and a 612 seat bar rib 29 is arranged between the angles of the two web members. In addition, single supports 28 are arranged on both sides of the web members, and each single support 28 has a size of Φ456X12.

[0081] In this embodiment, the living building 20 adopts standardized design units. Each unit includes three parts: main structure, interior decoration and equipment system. The main structure adopts lightweight and high-strength materials, the interior decoration adopts environmentally friendly materials, and the equipment system includes independent air conditioning, fresh air and smart home systems. The units of the living building 20 are connected by standardized interfaces, which not only ensures the structural strength, but also facilitates later transformation and replacement. Specifically, the multifunctional living building 20 is built with lightweight and high-strength composite materials, with an overall height of 40 meters and divided into 10 floors. The top floor is the driving cab, which adopts a 360-degree panoramic design and is equipped with a radar system, a meteorological monitoring system, an automatic ship identification system (AIS) and an emergency control center; the second to ninth floors are living areas, with a standard cabin size of 6m×4m×3m, a sound insulation performance of not less than 45dB, and a fresh air volume of 100m 3 / h·person ventilation system, and an air-conditioning system with independent temperature control and a temperature range of 16-30℃; the first floor is a public area, with a conference room that can accommodate 100 people, a restaurant that can accommodate 300 people at the same time, and a leisure area equipped with a gym and a library.

[0082] The intelligent control system includes a central control system, a security monitoring system and an environmental control system. The central control system can monitor the operating status of each system in real time, automatically adjust energy distribution, and has the function of automatic fault diagnosis and processing; the security monitoring system integrates functions such as automatic fire alarm, video monitoring coverage, personnel location tracking and emergency escape guidance; the environmental control system is responsible for air quality monitoring, automatic temperature and humidity adjustment, real-time noise monitoring and intelligent lighting control to ensure the comfort of the living environment.

[0083] In normal operation mode, the system automatically monitors environmental parameters in each area, adjusts ventilation and air conditioning according to the distribution of personnel, adjusts lighting and supplementary lighting according to the intensity of sunlight, and records energy consumption data in real time. When an emergency occurs, the system automatically switches to emergency handling mode, quickly identifies the type of emergency, activates the corresponding emergency plan, controls the evacuation route of personnel, and links the fire rescue system to ensure the safety of personnel. Through this intelligent design concept, this embodiment achieves the unity of comfort and safety of the offshore living environment, providing personnel with a good working and living space.

[0092] Example 4

[0093] like Figure 26-30 As shown, the difference between this embodiment and embodiment 3 is that, in this embodiment, 8 8MW wind turbines are arranged on both sides of the truss support structure 2, 4 on each side, a total of 64MW, and the 8 8MW wind turbines are all arranged in the rear half of the hull 1, and the 64MW wind turbines are connected to a 200MWh battery through a transmission cable. Different from other embodiments, the outer diameter of the wind rotor of each wind turbine 1501 is Φ160m.

[0094] The truss support structure 2 in this embodiment is also different from the truss support structure 2 in embodiments 1-3. The truss support structure 2 in this embodiment is composed of multiple webs and upper beams 203 arranged on the webs to form multiple continuous triangular structures or multiple sawtooth structures. The size of the top upper beam 203 is Φ3400X49, the total length of the upper beam 203 is 1877m, the web is Φ2020X22, and a seat bar rib 29 with a size of δ12 is provided between the two webs.

[0097] In this embodiment, there is also a living building 20, and the specifications of the living building 20 refer to the living building 20 in this embodiment 2.

[0098] The enclosed floating giant ship of this embodiment has an overall length, width and height of 2013mX144mX69m, a deadweight of 20t (including wind turbines, batteries, fresh water and consumables, etc.) of the hull 1, a rated displacement of 995,000t (maximum of 2.34 milliont), a rated commercial load of 795,000t, a rated draft of 3.63m (maximum of 8.53m), a rated speed of 10 knots (maximum of 12 knots), and a propulsion device of 4 8MW electric propellers (2 at the front end of the hull 1 and the other 2 at the rear end of the hull 1).

[0099] The technical effects that can be achieved by the enclosed floating giant ship in the above four embodiments include the following:

[0100] 1. The present invention adopts innovative flanged core material to make a closed pontoon, and utilizes the sandwich structure of "panel-sandwich layer-panel" and flexible core tube array design, which not only significantly improves the compression resistance, fatigue resistance and overall stability, but also greatly reduces the weight of the structure. Compared with traditional steel structures, this design can save about 70% of steel, thereby reducing material costs and construction difficulties.

[0101] 2. The hull foundation, which consists of about 1,500 independent enclosed buoys, adopts a modular partition design. Even in the event of local damage or extreme accidents (such as accidents or war), the buoyancy of the entire hull can be balanced to avoid the risk of overall sinking. The multi-buoy distributed buoyancy control system and redundant design provide "triple insurance" for the mobile city at sea, greatly improving safety.

[0102] 3. With standardized interfaces and modular design concepts, the enclosed buoy, truss support structure, cabin system and cargo handling equipment are all prefabricated, built in sections and quickly assembled. The integration of the automated crane system and the intelligent control system not only improves the efficiency of cargo handling and personnel management, but also reduces labor costs by about 95%, while facilitating later maintenance, replacement and functional upgrades.

[0103] 4. The entire giant ship can not only provide multiple functions such as residence, commerce, tourism and trade as a mobile city at sea, but also achieves dual optimization of functional zoning and carrying capacity through reasonable space stratification and cabin design (such as cargo storage area, equipment control layer and commercial living space). The hull design can accommodate 70,000 people to work and live, with a rated displacement of up to 2.1 million tons, a commercial load of 1 million tons, and flexible applicability in various scenarios.

[0104] 5. The truss support structure is composed of key components such as main columns, diagonal braces and upper beams connected by standardized nodes. The inner ring ribs, rib plates and cross-bracing components used in the design ensure the stability of the overall structure and uniform force distribution. In addition, the hull has achieved an improvement in overall structural stiffness and enhanced fatigue resistance under the reasonable arrangement of wind turbines and other ancillary facilities.

[0105] 6. The wind turbine installed at the stern of the hull or on the truss can stably supply more than 400MW of electricity through the symmetrical arrangement of the double wings and the coordinated work with the battery system, meeting the energy needs of various facilities on board (including electric propellers, lighting, control systems, etc.), greatly reducing the environmental impact during operation and improving energy utilization efficiency.

[0106] 7. The innovative layout design of the runway, circular and rectangular aprons enables large passenger aircraft (such as the 747) to take off, land and dock safely. The beam system, guardrail, drainage and lighting system in the runway and apron not only meet the requirements of heavy-load take-off and landing, but also provide reliable safety protection in emergency situations, ensuring stable operation around the clock.

[0107] 8. There are multiple high-rise buildings and comprehensive commercial facilities on the upper floors, which are equipped with integrated pipeline systems (power supply, communication, water supply and drainage, etc.) to provide residents with a comfortable and safe living and working environment. At the same time, the intelligent monitoring and management system monitors all operational indicators of the entire ship in real time 24 hours a day, further improving the overall safety and service level.

[0108] In general, this embodiment achieves a number of technological breakthroughs, such as lightweight structure, high safety, diverse functions, efficient construction and maintenance, environmental protection and energy saving, by adopting advanced composite materials and structural optimization technology, modular partition design, intelligent automation system and green energy solutions. It provides practical technical support for building a mobile maritime city that can accommodate 70,000 people, has high carrying capacity and multiple guarantees.
