Description

Technical Field

[0001] The present invention relates to the technical field of ship replenishment, and in particular to an offshore replenishment platform, a self-service replenishment system and a method. Background Art

[0002] With the continuous development of the ocean, the role of the ocean in the development of the national economy has become increasingly important. Various types of ships, such as fishing boats, marine surveillance ships, coast guard ships, and engineering ships, have played a variety of roles in the development of the marine economy and played a very important role. In addition, the "International Shipping Carbon Intensity Code" issued by the International Maritime Organization has put forward requirements for ship carbon emissions from two levels: the energy efficiency index (EEDI and EEXI) at the ship hardware level and the CII carbon intensity rating of operating ships at the ship operation level, which further promoted the development of new energy ships and pure electric ships.

[0003] For all kinds of ships such as fishing boats, marine surveillance ships, coast guard ships and engineering ships, stable and continuous work at sea is the cornerstone of the development of the marine economy. However, due to the small number of fixed supply bases during the ocean voyage, the uncertainty of subsequent supply increases and some ships use electric propulsion or pure electric propulsion. When such ships are sailing at sea, fuel, food, fresh water and electricity will be continuously consumed. For ships performing ocean voyage missions, the consumption of these materials will have a great impact on their endurance. When ships are performing tasks, they will be affected by waterways, ports, the environment they are in and other more complex factors, and may not be able to dock in real time for replenishment. At the same time, due to the long transportation distance, long replenishment time and many turnover links, island and reef transportation and supply have always been the main problems faced by island and reef logistics support. If a ship is to work normally, its consumed resources need to be replenished in a timely manner, so the status of the supply ship in the navigation of the ship cannot be underestimated. The power and fresh water resources provided by the offshore supply station can improve the endurance of these ships, thereby increasing the duration of their maritime operations or law enforcement. The traditional, most widely used lateral replenishment is only suitable between ships with special equipment. During replenishment, the two ships are relatively close and their relative positions cannot change significantly, so the commander is required to have a high level of control. Once an operational error or mechanical failure occurs, serious accidents can easily occur.

[0004] In summary, the existing temporary replenishment of ships at sea has technical problems such as strict conditions, high manpower consumption, and difficulty in replenishment. Summary of the invention

[0021] The purpose of this application is to overcome the above-mentioned technical deficiencies, propose an offshore supply platform, a self-service supply system and method, and solve the technical problems of strict conditions, high manpower consumption and great difficulty in supply in the existing technology.

[0022] In order to achieve the above technical objectives, this application adopts the following technical solutions: In the first aspect, the present application provides an offshore supply platform, such as Figure 1 and Figure 2 As shown, Figure 1 It is a structural schematic diagram of an offshore supply platform provided in an embodiment of the present application; Figure 2It is a structural schematic diagram of a supply boom module 5 provided in an embodiment of the present application.

[0023] An offshore supply platform includes an energy module, a fresh water module, a supply boom module 5 and a control module: An energy module, wherein the energy module comprises a power generation device, a battery pack 1 and a transmission line 2, wherein the battery pack 1 is connected to the power generation device and the transmission line 2 respectively; A fresh water module, the fresh water module comprising a fresh water tank 3 and a fresh water delivery pipeline 4, the fresh water tank 3 being in communication with the fresh water delivery pipeline 4; A supply boom module 5, the supply boom module 5 comprising a lifting arm 51, a telescopic mechanism 52, a slewing mechanism 53 and two pulleys 54, the telescopic mechanism 52 and the slewing mechanism 53 are both located at the bottom end of the lifting arm 51, the two pulleys 54 are both located at the top end of the lifting arm 51 and carry the power transmission line 2 and the fresh water delivery pipeline 4 respectively; and A control module, wherein the control module is connected to the supply boom module 5.

[0024] The embodiment of the present application performs the replenishment operation by modifying the replenishment boom module 5 on the offshore replenishment platform, and the replenishment boom module 5 is used to efficiently transfer fresh water and electric energy between ships. Compared with the traditional manual replenishment method, this method reduces the personnel consumption and cost on the supply platform, has obvious advantages in flexibility and convenience of operation, and allows each ship to carry out safe and efficient material transfer under certain distance and angle fluctuations. The offshore supply platform can also provide reliable and continuous replenishment measures through energy modules and fresh water modules to alleviate the resource shortage problems that offshore ships may face during navigation, such as insufficient fresh water or electric energy. By alleviating these problems, the survival and operation capabilities of ships at sea are improved, especially for ships with more frequent replenishment needs, such as fishing boats and pure electric propulsion ships. The replenishment boom module 5 makes the operation of the supplied ship during the replenishment operation more simple and reliable, reduces the workload of the operator, and reduces the risk of errors and accidents during the replenishment process. The navigation safety and endurance of the ship are further guaranteed, and the system not only improves the replenishment efficiency, but also improves the overall operational safety and reliability.

[0025] In some embodiments of the present application, the power generation device includes a solar generator 6 , a wind generator 7 and a charging line 8 , and the solar generator 6 and the wind generator 7 are both connected to the battery pack 1 via the charging line 8 .

[0026] In this embodiment, the solar generator 6 and the wind generator 7 store the generated electric energy in the battery pack 1 through the charging line 8. The use of these two renewable energy sources ensures that the platform can generate electric energy continuously and environmentally friendly. The electric energy stored in the battery pack 1 can be distributed and used through the ship power station 12. As a key part of energy management, the ship power station 12 ensures the effective use and stable supply of electric energy.

[0027] In some embodiments of the present application, the fresh water module includes a fresh water generator 9, a seawater pump 10 and a seawater pipeline 11. The fresh water generator 9 is connected to the fresh water tank 3 and the seawater pump 10 respectively, and the seawater pump 10 is connected to external seawater through the seawater pipeline 11.

[0028] In this embodiment, the seawater pump 10 extracts seawater from the outside of the platform through the seawater pipeline 11. The extracted seawater is sent to the fresh water generator 9 and converted into fresh water through desalination or other treatment methods. The produced fresh water is stored in the fresh water tank 3 through the fresh water delivery pipeline 4, waiting for use in the replenishment stage. When replenishment is needed, the stored fresh water and electric energy are delivered to the ship to be replenished through the replenishment boom module 5 or other replenishment methods.

[0029] In some embodiments of the present application, the energy module further includes a ship power station 12, and the ship power station 12 is electrically connected to the battery pack 1 and the fresh water generator 9 respectively.

[0030] In this embodiment, during the desalination and electric energy storage phase: when the system is working, the electric energy generated by wind power and sunlight power generation is stored in the battery pack 1 through the charging line 8, and the electric energy in the battery pack 1 drives the fresh water generator 9 and the seawater pump 10 through the transmission line 2 and the ship power station 12. The seawater pumped by the seawater pump 10 is converted into fresh water through the fresh water generator 9, and the fresh water is stored in the fresh water tank 3 through the fresh water delivery pipeline 4. The stored fresh water and electric energy will be delivered to the ship to be supplied during the replenishment phase.

[0031] Using solar energy and wind energy as energy sources reduces dependence on fossil fuels, which complies with the latest EEDI specifications for ships and the requirements for sustainable development of the national energy strategy. By extracting fresh water from seawater through the fresh water generator 9, the platform can achieve self-sufficiency in fresh water in sea areas far from land. The integrated ship power station 12 and battery group 1 improve the management efficiency and utilization efficiency of electric energy.

[0032] In some embodiments of the present application, the control module includes a control console 13, a wind speed sensor 14, an inclination sensor 15 and an electromagnetic odometer 16, and the control console 13 is signal-connected to the wind speed sensor 14, the inclination sensor 15, the electromagnetic odometer 16 and the supply boom module 5 respectively.

[0033] In this embodiment, the tilt sensor 15 (IS1A10P20), the electromagnetic speed meter 16 (CDJ), and the wind speed sensor 14 (ZXYD-AM706) respectively collect the tilt angle, speed, and wind speed data of the ship. The collected data are transmitted to the bridge 13 through the signal line 18. The bridge 13 sends the received data to the ship to be supplied through the ship-borne automatic identification system (Automatic Identification System, AIS) so that it can evaluate the supply conditions.

[0034] In some embodiments of the present application, the fresh water module includes a liquid level sensor 17, which is located in the fresh water tank 3 and is signal-connected to the console 13; the energy module includes a battery management module, which is electrically connected to the battery pack 1 and signal-connected to the console 13.

[0035] In this embodiment, the inclination sensor 15 and the original electromagnetic odometer 16, wind speed sensor 14 and the detected signals are fed back to the bridge 13 via the signal line 18, and the above data are sent to the ship to be supplied through the ship-borne AIS to determine whether it can be supplied.

[0036] If replenishment is possible, the liquid level sensor 17 in the water storage tank and the battery management system (BMS) of the battery pack 1 will send the amount of fresh water and power of the replenishment ship to the bridge 13 through the signal line 18, and the shipboard AIS will send the above data to the ship to be replenished.

[0037] The liquid level sensor 17 (float type 1043-P) is located in the fresh water tank 3, monitors the fresh water storage in real time, and sends the data to the bridge 13 through the signal line 18. The battery management module (Saft Battery Management System) monitors the status of the battery pack 1 and sends the relevant information to the bridge 13 through the signal line 18.

[0038] The ship to be replenished determines whether it can be resupplied safely based on the received inclination, speed, wind speed data as well as its own maneuverability and the driver's skill level.

[0039] The ship to be replenished determines whether the replenishment ship in the replenishment platform can meet its replenishment needs based on the received fresh water storage and power data. If it can, it will prepare to dock for replenishment; if not, it will consider other replenishment ships in the same supply platform.

[0040] In some embodiments of the present application, the supply boom module 5 further includes a visual recognition component, which is located at the top of the boom 51 and is signal-connected to the driving console 13 .

[0041] In this embodiment, the ship to be supplied is equipped with a dedicated remote controller. After docking at the supply platform, the user can use the remote controller to control the boom 51 to turn to the ship to be supplied. The user determines whether the position of the boom 51 reaches the appropriate position based on the signal transmitted by the visual recognition module carried by the boom and the on-site conditions. If the position is not appropriate, the telescopic mechanism 52 can be controlled to telescope the boom 51, or the slewing mechanism 53 can be controlled to rotate the boom 51; if the position is appropriate, the user controls the winch 55 on the boom 51 to rotate, release the joint of one end of the fresh water delivery pipeline 4 and the power transmission line 2 to the deck of the ship to be supplied, and connect the joint of one end of the fresh water delivery pipeline 4 on the boom 51 and the power transmission line 2 to the relevant pipelines and lines on the ship to be supplied. After the connection is completed, the user inputs the supply amount of fresh water and electric energy through the remote controller, and the supply platform supplies the ship to be supplied. After the supply is completed, the user needs to operate the remote controller to control the boom to return to the bracket to complete the supply.

[0042] The visual recognition component is located at the top of the crane arm 51, connected to the driving console 13 through a signal line, and transmits visual data in real time.

[0043] The user on the ship to be supplied uses a remote control to manipulate the steering, extension and rotation of the boom according to the image signal transmitted by the visual recognition component to accurately align with the position of the ship to be supplied.

[0044] When the boom is in a suitable position, the user controls the winch 55 to rotate and release the joints of the pipes and lines to the deck of the vessel to be supplied.

[0045] The user connects the water pipe and cable connectors on the boom to the corresponding connectors on the vessel to be supplied.

[0046] After the connection is completed, the user enters the required amount of fresh water and electricity supply through the remote control.

[0047] The supply platform begins to supply fresh water and electricity to the ships to be supplied based on the data entered by the user.

[0048] After the replenishment is completed, the user uses the remote control again to control the boom to return to the initial position to complete the replenishment operation.

[0049] The use of visual recognition components greatly improves the accuracy of the boom to align with the vessel to be supplied, reducing operational errors. The use of remote control makes the supply operation easier, and users can remotely control the boom without manual climbing or complex operations. By directly entering the supply amount through the remote control, the supply process can be quickly started, improving the efficiency of supply. The design of the boom module enables the supply platform to adapt to ships of different sizes and types, improving the flexibility of supply. Automation and remote control operation reduce the required human resources and reduce operating costs.

[0050] In some embodiments of the present application, a plurality of supply ships are included, and the plurality of supply ships are connected end to end, and each of the supply ships includes the battery pack 1 and the fresh water tank 3 .
