Description

Technical Field

[0001] This application relates to the field of ship safety protection technology, and more specifically, to a device for preventing damage to equipment on a supply ship during replenishment, a ship replenishment system using the same, and a ship. Background Technology

[0002] Currently, when ships require refueling during long-distance voyages, a cable connection is typically established between the supply ship and the receiving ship. This cable is used to pull a refueling pipeline between the two vessels. The receiving ship is equipped with a dedicated refueling tank and corresponding refueling pipelines. After all refueling-related valves on the receiving ship are opened, the receiving ship instructs the supply ship to activate its fuel supply pumps, and the supply ship begins refueling the receiving ship. Once refueling is complete, the receiving ship instructs the supply ship to deactivate its fuel supply pumps. After the supply ship's fuel supply pumps are deactivated, the receiving ship closes all relevant refueling valves.

[0003] However, this resupply method has significant safety risks. In order to meet the needs of long-distance resupply, the fuel supply pumps on the resupply ship are usually under high pressure. When the resupply valve on the resupply pipeline on the receiving ship is damaged and the resupply pipeline is blocked, the pressure on the resupply pipeline will be too high, which will damage the fuel supply pumps and other equipment on the resupply ship.

[0004] Some technologies can be used for automatic quantitative replenishment of ship fuel, reducing manual operation and increasing automation, but they still do not address the safety of the replenishment process. Utility Model Content

[0005] The purpose of this application is to provide a ship replenishment safety protection device, a ship replenishment system, and a ship, which aims to solve the problem of excessive pressure in the replenishment pipeline caused by the failure of valves related to replenishment of oil tankers during the ship replenishment process in the prior art.

[0006] Furthermore, this invention can prevent damage to equipment on replenishment ships, such as fuel replenishment pumps.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] A ship replenishment safety protection device, characterized in that it includes a main replenishment pipeline and a replenishment bypass pipeline installed between the replenishment ship and the oil receiving ship;

[0009] A main supply pipeline is formed between the supply port of the receiving vessel and the receiving tank of the receiving vessel. A first on / off valve is installed on the main supply pipeline to control the opening and closing of the main supply pipeline.

[0010] The second open-close valve is arranged on the supply bypass pipeline and is used for controlling the opening and closing of the supply bypass pipeline.

[0011] In the technical scheme, one end of the supply bypass pipeline is connected to the supply main pipeline after the supply port of the receiving ship and before the inlet of the first open-close valve, and the other end is connected to the oil inlet of the receiving cabin.

[0012] In the technical scheme, the oil outlet of the supply ship and the supply port of the receiving ship are connected through the supply pipeline pulled by the cable, and the supply main pipeline is connected through the pipeline of the supply pipeline.

[0013] In the technical scheme, the supply bypass pipeline and the supply main pipeline are made of high-pressure-resistant materials.

[0014] In the technical scheme, the second open-close valve is a hand-operated stop valve and can be kept in an open state during the supply.

[0015] In the technical scheme, at least one pressure monitoring device for monitoring the pressure of the supply main pipeline is further included, and the pressure monitoring device is configured to automatically open the second open-close valve when the pressure of the supply main pipeline exceeds a preset value.

[0016] In the technical scheme, the supply ship cuts off the supply connection with the receiving ship by opening or closing the fuel supply pump.

[0017] A ship supply system, characterized in that it comprises the ship supply safety protection device according to any one of the preceding technical schemes.

[0018] A ship, characterized in that it comprises the ship supply safety protection device according to any one of the preceding technical schemes and is used for ensuring the safety of the ship during the oil supply.

[0019] A ship supply method using the ship supply safety protection device, characterized in that it comprises the following steps:

[0020] The oil outlet of the supply ship and the supply port of the receiving ship are connected through the supply pipeline pulled by the cable, and the supply main pipeline is connected through the pipeline of the supply pipeline.

[0021] The first open-close valve and the second open-close valve are simultaneously opened, or the first open-close valve is first opened, and then the second open-close valve is opened after the pressure rises to a set value, and the pressure set value is comprehensively judged and set in combination with the take-off pressure of the safety valve of the fuel supply pump of the supply ship and the pressure of the supply pipeline.

[0022] In essence, opening both valves simultaneously is sufficient to meet safety standards. This ensures that both the pipeline and the receiving ship can withstand the high pressure (typically 0.5 MPa-1 MPa) at the outlet of the fuel supply pump 2.

[0023] After the receiving ship notifies the supply ship to start the supply, the supply ship starts to supply fuel to the receiving ship.

[0024] After the supply is completed, the supply ship stops the supply, and the receiving ship closes the first on-off valve to cut off the supply main pipeline.

[0025] In the above technical solution, the supply ship cuts off the supply communication with the receiving ship by opening or closing the fuel supply pump.

[0026] A method for constructing a ship supply safety protection device, characterized by the steps of constructing a supply bypass pipeline and a supply bypass on-off valve, and installing them between the supply main pipeline and the receiving tank.

[0027] In summary, the present application relates to a ship supply safety protection device, which aims to solve the problem of excessive pressure in the supply pipeline caused by the failure of the receiving ship's supply-related valves during the ship supply process. The device includes a supply bypass pipeline and a supply bypass on-off valve. The supply bypass pipeline is connected to the receiving tank inlet after the receiving ship's oil inlet and the supply main pipeline. The supply bypass on-off valve is installed on the supply bypass pipeline and is used to maintain an open state during the supply process to prevent the supply pipeline pressure from being too high.

[0028] The ship supply safety protection device of the present application has the following advantages in addition to the basic functions of preventing excessive pressure and protecting equipment:

[0029] Improving supply efficiency: By designing a bypass pipeline, even in the case of receiving ship valve failure, fuel flow can be maintained, reducing interruptions caused by failures.

[0030] Reducing maintenance costs: Reducing equipment damage caused by excessive pressure, thereby reducing maintenance costs and downtime.

[0031] Enhancing operational flexibility: The supply bypass on-off valve can be manually controlled, providing operators with more control options to handle different supply situations.

[0032] Improving safety: Reducing the risk of leaks and explosions caused by excessive pressure, protecting crew safety.

[0033] Environmentally friendly: Reducing fuel leaks caused by operator errors or equipment failures, reducing pollution of the marine environment.

[0034] The beneficial effects of the utility model include improving supply efficiency, reducing maintenance cost, enhancing operation flexibility, improving safety and environmental friendliness. BRIEF DESCRIPTION OF DRAWINGS

[0045] Example 1

[0046] exist Figure 1 In the middle, one end of the supply bypass pipeline 8 is connected to the oil receiving vessel ( Figure 1 (Not shown in the image) The supply port 4 is connected to the main supply pipe 5. It is installed before the supply valve or the first on / off valve 6 of the main supply pipe 5, and one end is connected to the oil inlet of the receiving tank 9.

[0047] exist Figure 1 In this process, a replenishment bypass switch valve or a second on / off valve 7 is installed on the replenishment bypass pipeline 8. When the replenishment bypass switch valve 7 is opened, a passage is formed between the replenishment main pipeline 5 and the receiving tank 9. Specifically, it is set between the replenishment port of the receiving vessel and the oil inlet of the receiving tank.

[0048] In this embodiment, the replenishment bypass pipeline 8 establishes a connection between the replenishment manifold 5 and the receiving tank 9 of the receiving ship, and the replenishment bypass switch valve 7 installed on the replenishment bypass pipeline 8 can open / close the replenishment bypass pipeline 8. The fuel supplied by the fuel replenishment pump 2 on the replenishment ship 1 can flow into the receiving tank 9 of the receiving ship (not shown in the figure) through the replenishment bypass pipeline 8. Figure 1

[0049] In Figure 1 , the replenishment ship 1 is a liquid fuel carrying replenishment ship, and the fuel replenishment pump 2 is a power device specially used for fuel replenishment on the replenishment ship 1, which is usually damaged due to excessive pipeline pressure,

[0050] In use, after the replenishment ship 1 is connected to the replenishment port 4 of the receiving ship (not shown in the figure) through the cable-drawn replenishment oil pipe 3, the replenishment related valve 6 on the replenishment manifold of the receiving ship (not shown in the figure) and the replenishment bypass switch valve 7 on the replenishment bypass pipeline 8 are opened, the receiving ship (not shown in the figure) notifies the replenishment ship 1 to open the fuel replenishment pump 2, and the replenishment ship 1 starts to supply fuel to the receiving ship (not shown in the figure). After the replenishment is completed, the receiving ship (not shown in the figure) notifies the replenishment ship 1 to close the fuel replenishment pump 2, and after the fuel replenishment pump 2 of the replenishment ship 1 is closed, the receiving ship (not shown in the figure) closes the replenishment related valve 6. Figure 1 Figure 1 Figure 1 Figure 1 Figure 1 Figure 1

[0051] According to the construction method of the ship replenishment safety protection device, the steps of constructing the replenishment bypass pipeline and the replenishment bypass switch valve are included, and they are installed between the replenishment manifold and the receiving tank. Specifically, it is arranged between the receiving port of the receiving ship and the oil inlet of the receiving tank.

[0052] In order to prevent high pressure of large ships, the replenishment bypass pipeline and the replenishment manifold are made of high-pressure resistant materials, so as to ensure the pressure resistance.

[0053] The first and second on-off valves are used to control the on-off of each replenishment pipeline, and the stop on-off valve is preferred.

[0054] Further, since the replenishment high-pressure oil condition changes very quickly and the on-site situation is urgent, the replenishment bypass switch valve or the second on-off valve is a manual stop valve, which can maintain a normal open state during replenishment.

[0055] ​​​​​​​Of course, the second open-close valve is set on the bypass, preferably with overflow effect of the stop valve, to further balance the pressure, avoid the damage of the supply valve or the first open-close valve on the supply pipeline of the receiving ship, which will cause the pressure of the supply pipeline to be too large, thereby causing the damage of the fuel supply pump and other equipment on the supply ship.

[0056] Embodiment 2

[0057] On the basis of Embodiment 1, a pressure monitoring device is set, the first open-close valve is first opened, and then the second open-close valve is opened after the pressure rises to the set value. The pressure set value is set in combination with the take-off pressure of the safety valve of the fuel supply pump on the supply ship and the pressure of the supply pipeline.

[0058] In essence, opening the two valves at the same time is already enough to reach the safety standard. Thus, both the pipeline and the receiving ship can withstand the high pressure (generally 0.5 MPa-1 MPa) of the outlet of the fuel supply pump 2.

[0059] The above-described embodiments are part of the embodiments of the present application, rather than all the embodiments. The detailed description of the embodiments of the present application is not intended to limit the scope of the claimed application, but only represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present application.
