Description

TECHNICAL FIELD

[0001] The present application relates to a green power comprehensive hub for a sea cruise ship. BACKGROUND

[0002] A modern passenger ship refers to a ship specially used for transporting passengers and their luggage, with more than 12 passengers on board. It generally has a superstructure with multiple decks for arranging passenger cabins and more complete dining and recreational facilities; and has good safety. A cruise ship refers to a passenger ship with a fixed route and regular sailing on the sea with a tourism nature. It is like a mobile hotel on the sea, equipped with complete accommodation and entertainment facilities, providing passengers with a comfortable and comfortable ocean tourism experience.

[0003] China's cruise industry is showing signs of recovery, and tourists are enthusiastic about taking cruises. However, in the South China Sea and similar sea areas, although the island and reef tourism resources are rich, and there is great potential for cooperation with Southeast Asian destination ports, there is still the following pain point:

[0004] China has a vast territory with a very long coastline. Among them, the mainland coastline is 18,400 km long, and the island coastline is 14,247 km long. The current domestic main cruise ports are located in Dalian, Tianjin, Shanghai and other North and East China regions. Therefore, if a cruise ship from the north departs from the home port and wants to develop a South China Sea route, it is inevitable to produce daytime sailing (i.e. sailing on the sea during the day, not stopping at tourist destinations. Tourists can only play on the ship).

[0005] South China Sea tourism is mostly islands and reefs, which do not have the possibility of building large-scale cruise terminals, and existing cruise ships cannot connect passengers to the island through their own facilities. North tourists cannot directly take a cruise to play in the South China Sea islands and reefs, making it difficult to fully develop South China Sea tourism resources.

[0006] The current domestic cruise brands mostly operate second-hand ships, and their theme entertainment is single compared to foreign large cruise ships. The public area on the ship is backward and cannot hold large-scale entertainment activities, limiting the development of independent cruise tourism products. At the same time, the passenger ships operating in the South China Sea area are relatively small in size, with relatively simple entertainment configurations and single play methods, and the price is high, with a small target audience.

[0007] The current international shipping industry regards green carbon reduction as the main trend for future development, and relevant energy-saving and emission-reduction acts and incentive and punishment mechanisms have also been introduced. The current domestic cruise ships are all powered by traditional fossil fuels, resulting in high carbon emissions during the entire voyage. First, it does not meet the development needs of the future shipping industry and may incur additional punitive costs in the future; second, the South China Sea ecosystem is relatively fragile, and the use of fossil fuels is not conducive to the protection of the South China Sea environment.

[0008] If you want to quickly solve the above background problems, it is urgent to launch an innovative mode and new concept product without making major changes to the operation of cruise ships: on the one hand, reduce the total carbon emissions of existing cruise routes, and change the boring daytime cruise into a more attractive "trendy" project.

[0009] Therefore, the offshore cruise ship green power comprehensive hub is proposed for the above problems. SUMMARY

[0010] The offshore cruise ship green power comprehensive hub provided by the present application overcomes the existing defects and provides power for marine tourism cruise ships.

[0011] The technical solution to achieve the above-mentioned purpose is: an offshore cruise ship green power comprehensive hub, comprising a relay mother ship hull and a green energy comprehensive body; the relay mother ship hull is long-term stationed at a designated route, and the green energy comprehensive body is arranged at a starting point of the route of the relay mother ship hull and used for refueling the relay mother ship hull.

[0012] Ten groups of connecting components are arranged on both sides of the relay mother ship hull for connecting cruise ships on both sides; one personnel flow corridor bridge is connected to each side of the relay mother ship hull for connecting the cruise ships on both sides to the relay mother ship hull.

[0013] Preferably, the connecting component comprises a structure reinforcement, a connecting arm support, a connecting arm device and a hull connecting piece; the structure reinforcement is arranged on the side wall of the relay mother ship hull, the connecting arm support is connected to the structure reinforcement, the structure reinforcement movably connects the connecting arm device, and the other end of the connecting arm device is connected to the hull connecting piece.

[0014] Preferably, the green energy comprehensive body comprises a renewable energy production cluster and a green energy production and filling platform; the renewable energy production cluster comprises an offshore wind power plant, a solar power plant, a wave power plant, a temperature difference power plant and a comprehensive power plant combining the above-mentioned power plants.

[0015] Preferably, the middle area of the relay mother ship hull is a central entertainment functional area, and an openable glass roof is arranged above the central entertainment functional area.

[0016] Preferably, three lateral thrusters are arranged at the front and rear of the relay mother ship hull; eight horizontal rotary thrusters are further arranged at the lower part of the relay mother ship hull.

[0017] Preferably, one driving cabin is arranged at the upper part of the front and rear of the relay mother ship hull; one glass dome garden is arranged below each of the two driving cabins.

[0018] Preferably, the hull connecting piece is an electromagnetic suction cup.

[0019] Preferably, the ship body connecting piece is a vacuum chuck.

[0020] Preferably, the relay mother ship body is provided with a shore power interface for supplying power to the two cruise ships.

[0021] The beneficial effects of the present application are: the offshore cruise ship green power comprehensive hub uses green fuel produced by the green energy complex as the main energy source, and long-term fixed-point and fixed-time cruises along the designated route: at the starting point, it meets two cruise ships starting from different domestic ports, connects with the two cruise ships through the connecting assembly, and uses the connecting corridor bridge of the mother ship to enable personnel on the three ships to transfer freely. At the same time, the mother ship uses the shore power equipment to connect with the power grid of the two cruise ships to provide power output for the cruise ships. The three ships jointly start the power device and sail towards the target sea area, during which passengers can freely walk and play on the three cruise ships. After arriving at the destination, the two cruise ships are disconnected from the mother ship and continue their respective voyages. The super-large three-body ship, the large special-shaped structure entertainment place, and the embedded underwater sightseeing boat overturn the cruise ship tourism mode and realize the "night sailing and day playing island" mode, which changes the daytime cruise into a unique and constantly changing "net red project", making the daytime cruise in short-term voyage no longer a problem, making it easier to plan and more popular to travel from northern ports to more distant South China Sea routes. At the same time, the green energy complex uses renewable energy (wind energy, solar energy, tidal energy, etc.) on the sea, uses carbon dioxide, nitrogen gas captured from exhaust gas or atmosphere, and hydrogen gas obtained by electrolysis to synthesize green methanol, green liquid ammonia, or green liquid hydrogen, etc. Green fuel to provide power source for the relay mother ship, realizing energy saving and low-carbon operation.

In addition, the terms "first", "second", "third" are only for the purpose of description, and cannot be understood as indicating or implying the importance of the opposite.

[0034] The application will be further described in combination with the drawings.

[0035] As Figures 1-10 shown, the offshore cruise ship green power comprehensive hub includes a relay mother ship hull 1 and a green energy comprehensive body; the relay mother ship hull 1 is long-term stationed at a designated route, and the green energy comprehensive body is arranged at the starting point position of the route of the relay mother ship hull 1 and is used for supplementing fuel for the relay mother ship hull 1; ten groups of connecting assemblies are arranged on both sides of the relay mother ship hull 1, which are used for connecting cruise ships 16 on both sides; one personnel flow corridor bridge 17 is connected to each side of the relay mother ship hull 1, which is used for connecting the cruise ships 16 on both sides to the relay mother ship hull 1.

[0036] Specifically, in the target sea area, a green energy complex is set up at a suitable location, and the green energy complex uses renewable electricity to synthesize green fuel. The relay mother ship uses green fuel produced by the green energy complex as the main energy source, and long-term fixed-point and fixed-time cruising is carried out along the established route: at the starting point, it is connected with two cruise ships starting from different domestic ports, and the connection assembly is used to connect with the two cruise ships 16, and the personnel flow corridor bridge 17 of the relay mother ship is used to enable personnel of the three ships to transfer freely. At the same time, the relay mother ship uses shore power equipment to dock with the power grid of the two cruise ships to provide direct power output for the cruise ships 16. The three ships start the power device together and sail towards the target sea area, during which passengers can walk and play on the three cruise ships. After arriving at the destination, the two cruise ships are disconnected from the mother ship and continue their respective voyages. The mother ship returns to the starting point, replenishes green fuel at the "green energy complex", and continues the next voyage cycle.

[0037] Specifically, the green energy complex includes a renewable energy production cluster and a green energy production and refueling platform; the renewable energy production cluster includes an offshore wind power plant, a solar power plant, a wave power plant, a temperature difference power plant, and a comprehensive power plant combining the above multiple power generation facilities.

[0038] Specifically, according to the calculation, in order to meet the sufficient green fuel production, a single renewable energy production cluster has at least 1000MW output power. Taking a 16MW wind turbine as an example, at least 63 offshore wind turbines are theoretically required.

[0039] Specifically, the green energy production and refueling platform is not fixed in form, and can be a semi-submersible platform or a floating production storage and offloading (FPSO) platform. However, regardless of the form, it has the following functions: 1. It can be connected with the renewable energy production cluster through a cable to obtain clean electricity; 2. It can use clean electricity to complete electrolytic hydrogen production; 3. It can use clean electricity to complete carbon dioxide air capture or nitrogen air capture; 4. It can use clean electricity to complete green methanol production (using carbon dioxide and hydrogen) or green liquid ammonia production (using nitrogen and hydrogen); 5. It has a large-capacity hydrogen storage tank under the sea for storing hydrogen; 6. It has a methanol storage cabin or a liquid ammonia storage cabin; 7. It has a refueling function, which can collect carbon dioxide from other ships with carbon dioxide capture devices, and can refuel the "relay mother ship" with green methanol, green ammonia, green hydrogen, etc.

[0040] Specifically, the whole hull 1 of the relay mother ship is designed as a basic symmetry from bow to stern, and the side view of the bow and stern is a bullet-shaped streamline shape; the middle part is a cylindrical structure. The full length is 570 meters, the maximum height is 110 meters, the ship width at the waterline is 72 meters, and the maximum ship width is 120 meters (the top deck expansion area). The main size is designed for docking 150,000-ton cruise ships, which can be adjusted according to actual docking needs, and the basic shape and structure remain unchanged.

[0041] As shown in Figure 1 , 2 , 3, the upper front and rear ends of the hull 1 of the relay mother ship are each provided with a driver's cabin 5; the upper front and rear ends of the hull 1 of the relay mother ship are each provided with a glass dome garden 4 below the two driver's cabins 5.

[0042] Specifically, the top ends of the bow and stern of the water part are the driver's cabin 5, and the two driver's cabins 5 have the same function and can switch the driving right according to the heading of the mother ship. The driver's cabin is directly below the fixed glass truss structure sheltering the multi-layer deck garden; below the garden, the area above the machinery space is the indoor public area and the crew accommodation area of the relay mother ship.

[0043] As shown in Figure 1 , 2 , 3, the bow and stern of the hull 1 of the relay mother ship are each provided with three lateral thrusters 7; the lower part of the hull 1 of the relay mother ship is also provided with eight horizontal rotation thrusters 8.

[0044] Specifically, the underwater part of the hull 1 of the relay mother ship is a trimaran type (the underwater part is composed of three pieces), which can offset the influence of the wide body on the hydrodynamic performance to the greatest extent and improve the stability of the whole ship. The bow and stern of the underwater middle hull are each provided with three lateral thrusters 7 to improve the maneuverability of the relay mother ship; the relay mother ship is equipped with a total of eight horizontal rotation thrusters 8, which can help the relay mother ship to complete the switching of forward and reverse movements without turning around.

[0045] As shown in Figure 8 , the middle area of the hull 1 of the relay mother ship is a central atrium entertainment functional area 10, and the central atrium entertainment functional area 10 is provided with an openable glass roof 6 above.

[0046] Specifically, the middle part of the hull 1 of the relay mother ship is a large multi-layer deck public area, the central atrium entertainment functional area 10, which has an internal single-layer deck area of up to 20,000 square meters and can accommodate 10,000 people and hold large-scale entertainment activities such as sports events and concerts. The top of the central atrium is sheltered by a horizontally openable openable glass roof 6, which can be closed on rainy days; the structure inside the two sides of the ship is empty for docking and connecting cruise ships.

[0047] Specifically, the relay mother ship body 1 itself has power, and the underwater part is mainly a mechanical place. Eight 21000kW methanol / ammonia fuel main engines are built in to provide power for the whole ship and the connected cruise ships. The total installed power can not only meet the energy consumption demand of the self operation and maintenance, but also meet the energy consumption of the two cruise ships at the same time. The mother ship uses methanol or hydrogen fuel cell as the energy source of the mother ship and the two cruise ships. The methanol fuel is obtained from the offshore "green methanol" or "green hydrogen" platform after electrolytic hydrogen production by offshore wind power.

[0048] As shown in Figure 6 , 7 , the connecting assembly includes a structural reinforcement 14, a connecting arm support 13, a connecting arm device 12 and a ship body connecting piece 11; the structural reinforcement 14 is arranged on the side wall of the relay mother ship body 1, the connecting arm support 13 is connected to the structural reinforcement 14, the connecting arm device 12 is movably connected to the structural reinforcement 14, and the other end of the connecting arm device 12 is connected to the ship body connecting piece 11. The ship body connecting piece 11 is an electromagnetic suction cup or a vacuum suction cup.

[0049] Specifically, the entertainment function area 10 below is the core area of the relay mother ship: the cruise ship connection and docking area. Ten sets of connecting devices are arranged on both sides of the area, and the system is composed of a ship body connecting piece 11, a connecting arm device 12, a connecting arm support 13 and a structural reinforcement 14. The ship body connecting piece 11 can be adsorbed on the cruise ship 16 through electric control, so that the relay mother ship body 1 and the cruise ship 16 are connected, and the ship body connecting piece 11 itself has a certain multi-degree-of-freedom compensation at the hinge to prevent hard connection from causing damage to the connecting structure. The connecting arm device 12 is a three-section folding hydraulic arm, which can keep the cruise ship 16 within a certain distance range from the relay mother ship body 1, and will not be too close or far away from the mother ship; the whole connecting arm device is electrically controlled and has a stress sensor built in, so that the parallel posture control of the two berthing cruise ships can be realized through the system, and the posture synchronization with the berthing cruise ship can be realized. At the same time, it can be automatically disconnected from the cruise ship in extreme sea conditions to ensure the safety of the mother ship and the cruise ship.

[0050] Specifically, the relay mother ship body 1 is provided with a shore power interface for supplying power to the two cruise ships 16 on both sides.

[0051] Specifically, the left and right sides of the relay mother ship body 1 can simultaneously dock two different cruise ships coming from different originating ports. After docking, the two cruise ships are connected to the mother ship power interface, and all power users are provided by the mother ship, and the "three-ship parallel" mode is started. In addition, the relay mother ship connection area is also provided with a shore power interface and a supply facility. It carries fuel, food and other supplies to supply passing ships.

[0052] The green power comprehensive hub of the sea cruise ship can be applied to a larger sea area. At present, the development of sea tourism routes in China is only the tip of the iceberg. In particular, it is difficult to reasonably plan the voyage from the northern port to the South China Sea, and it is inevitable to produce boring daytime cruises. Two cruise ships with similar scales are sent from different ports and meet on the relay power relay mother ship, allowing passengers to visit another cruise ship with one ticket and enjoy large-scale entertainment events held on the mother ship in a paid state. The green power comprehensive hub of the sea cruise ship overturns the traditional cruise operation mode and greatly realizes the low-carbon operation of the cruise ship at sea, mainly reflected in:

[0053] 1. Without modification, the carbon emissions of the operating cruise ship during the entire voyage can be greatly reduced;

[0054] The operating cruise ship 16 moored on the mother ship hull 1 accesses the power supply system on the mother ship through the shore power interface. If its own propulsion system is a traditional shaft propeller, it can be disabled, and if it is an all-electric propulsion, it can continue to be turned on. All life support and entertainment power in the cruise ship is supplied by the mother ship, and the fossil fuel main engine of the cruise ship does not work during the "three-body parallel" period. The cruise ship moored on it realizes 0 carbon emissions during parallel voyage.

[0055] 2. More choices are provided for the planning of existing cruise routes;

[0056] Chinese people have short holidays. For young passengers with more consumption capacity and more advanced consumption concepts, it is inevitable to have daytime cruises when taking a cruise ship from a northern port to the South China Sea. As Chinese people become more familiar with cruise tourism, the current single theme on the cruise ship has been difficult to alleviate the boredom of daytime cruising, and the optimal "night cruising, daytime island playing" mode is difficult to achieve. The appearance of the green power comprehensive hub of the sea cruise ship changes the daytime cruise into a very characteristic and constantly changing "trendy project", making the daytime cruise in the short voyage no longer a problem. The route from the northern port to the more distant South China Sea destination will therefore be easier to plan and more popular.

[0057] 3. Larger public activities can be held in the super-large public area on the mother ship;

[0058] The relay mother ship hull 1 provides green energy to the moored cruise ship 16, and the super-large public space provided on it can provide public performance space that a single cruise ship cannot provide. Through the holding of concerts, show courts and other activities, passengers on two cruise ships can be attracted to purchase tickets at the same time. The mother ship only provides green energy and large public areas, and has no other living quarters except a small number of staff, becoming a new type of cruise tourism service complex.

[0059] 4. Customized sea green energy island, efficient production and sales of green energy;

[0060] Customized offshore wind farm and its green energy production platform system will realize "production and sale simultaneously" after energy conversion. The platform can digest carbon sources provided by third-party carbon capture and use the electricity provided by surrounding wind power piles to electrolyze water to produce hydrogen, simultaneously synthesize green methanol and green ammonia. After completing the task voyage, the relay mother ship will go to the green energy production platform for fast refueling of green methanol and green ammonia to realize green energy "fast charging".

[0061] 5. Open up a new growth point of cruise ship industry service outside the traditional cruise ship profit model;

[0062] The competition of traditional cruise companies is to provide services for passengers, with on-board and onshore entertainment and sightseeing as the core selling points. The offshore cruise green power comprehensive hub provides green energy to cruise ships and enhances passengers' experience by docking two different theme cruise ships with similar tonnage. With one ticket, passengers can experience the entertainment programs of two different cruise ships. These "visiting" experiences are all chargeable. In terms of offshore cruise entertainment, a win-win "Taobao platform" has been formed among different cruise ships and cruise companies. Passengers may want to experience the latest cruise ship but back down due to high ticket prices. However, because of the encounter at sea, even if they board a low-end cruise ship with low ticket prices, they can still choose to enjoy a dinner at the high-end cruise ship restaurant or enjoy a large-scale concert on the mother ship. Cruise companies and passengers have more choices, which is a new growth point of cruise industry service.
