Description

Technical Field

[0001] This invention belongs to the field of marine technology, specifically relating to a method for adding water to a semi-submersible barge. Background Technology

[0002] The ship was launched and moved to a semi-submersible barge. According to the requirements for floating state: the heel should be controlled within 0.5 degrees; the trim should be controlled within 1% LBP. More than 2,000 tons of water need to be added to some ballast tanks to adjust the floating state of the ship. At present, the water filling method of the semi-submersible barge is to use a water hose and water pump to directly pump water from the ship launching area outside the semi-submersible barge to the corresponding ship ballast tanks. Since the semi-submersible barge has its own ballast adjustment function, when ballast water is loaded into the ship's ballast tanks, the semi-submersible barge will submerge with the ship. However, this water filling method has the following drawbacks: (1) The water filling path is single, time-consuming and labor-intensive. The water hose is prone to leakage and flow loss during the water filling process, resulting in reduced water filling efficiency and long water filling cycle, which cannot meet the production plan requirements. (2) When adding water, the height from the water surface to the vent pipe of the ship's ballast tank is about 28 meters, and the total length of the water adding pipeline is more than 40 meters. The head of the water adding pump, the water adding pressure and the flow rate are limited in the conventional water adding method. (3) The bow and stern orientation of the ship is not fixed. According to the requirements of the ship's floating state after launching, water is usually added to the bow ballast tank and the forepeak tank. A single water adding pipeline cannot meet the water adding requirements of the bow ballast tank and the forepeak tank. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a method for water filling a semi-submersible barge, so as to overcome the defects mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0005] A method for watering a semi-submersible barge includes a semi-submersible barge, which has a loading deck and four towers located at the top corners of the loading deck: a port bow tower, a starboard bow tower, a port stern tower, and a starboard stern tower. The bottom of the semi-submersible barge is equipped with multiple ballast tanks and multiple pump rooms, each pump room containing a seawater tank. The method includes the following steps:

[0006] S1: Construct a first seawater steel pipe and a second seawater steel pipe. The first seawater steel pipe is fixed to the outside of the left bow tower by a first bracket, and the second seawater steel pipe is fixed to the outside of the right stern tower by a second bracket; or, the first seawater steel pipe is fixed to the outside of the left stern tower by a first bracket, and the second seawater steel pipe is fixed to the outside of the right bow tower by a second bracket.

[0007] S2: When the vessel is not loaded with ballast water, it is towed to the loading deck by a ship transfer vehicle. The bottom of the vessel is equipped with multiple ballast tanks.

[0008] S3: Connect the bottom end of the first seawater steel pipe to the seawater tank through the first pump body, and open multiple first filling ports on the first seawater steel pipe. The first filling ports are connected to the corresponding ship ballast tanks through the first water filling hoses.

[0009] S4: Without following the order of step S3, the bottom end of the second seawater steel pipe is connected to the seawater tank through the second pump body, and multiple second filling ports are opened on the second seawater steel pipe. The second filling ports are connected to the corresponding ship ballast tanks through the second water filling hoses.

[0010] S5: Ballast water is loaded into the corresponding ballast tanks of the ship through the first pump body and the second pump body respectively.

[0011] As a preferred embodiment of the present invention, in step S2, a plurality of first filling ports are formed above the top deck of the port bow tower or above the top deck of the port stern tower.

[0012] As a preferred embodiment of the present invention, in step S3, a plurality of second filling ports are formed above the top deck of the right bow tower or above the top deck of the right stern tower.

[0013] As a preferred embodiment of the present invention, the first filling port is provided with a first flange-type hydraulic connector for connecting the first water filling hose; the second filling port is provided with a second flange-type hydraulic connector for connecting the second water filling hose.

[0014] As a preferred embodiment of the present invention, it further includes a first flange blind plate for sealing the first filling port and a second flange blind plate for sealing the second filling port; the first flange blind plate can be connected to the first flange-type hydraulic joint, and the second flange blind plate can be connected to the second flange-type hydraulic joint.

[0015] As a preferred embodiment of the present invention, both the first water inlet hose and the second water inlet hose are suction hoses wrapped with wear-resistant rubber and steel wire.

[0016] As a preferred embodiment of the present invention, the inlet end of the first pump body is provided with a first filter, and the outlet end of the first pump body is provided with a first manual butterfly valve; the inlet end of the second pump body is provided with a second filter, and the outlet end of the second pump body is provided with a second manual butterfly valve.

[0017] The water-filling method for a semi-submersible barge provided by this invention has the following advantages compared with the prior art:

[0018] (1) The present invention utilizes the original tower structure of the semi-submersible barge to arrange steel pipelines (i.e., the first seawater steel pipe and the second seawater steel pipe). At the same time, since the first seawater steel pipe and the second seawater steel pipe are equipped with multiple filling ports, the filling ports are quickly connected to the ship's ballast tanks through water filling hoses, and ballast water is loaded from the seawater tank of the semi-submersible barge to the corresponding ship's ballast tanks through the pump body. Compared with the existing technology of using a water hose with a single water filling path for water filling, by optimizing the pipeline layout, losses can be reduced and water filling efficiency can be improved, so that the water filling cycle is shortened and the production plan requirements are met.

[0019] (2) In this invention, the first seawater steel pipe and the second seawater steel pipe are respectively set on the bow tower and the stern tower and arranged diagonally, so that the ship can be launched from either bow or stern and will not affect the normal operation of the semi-submersible barge, and can be conveniently managed in a fixed position.

Therefore, they should not be construed as limitations on the invention. It should be understood that the terms "first," "second," etc., are used in this invention to describe various information, but this information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this invention, "first" information can also be referred to as "second" information, and similarly, "second" information can also be referred to as "first" information.

[0029] Please see Figures 1 to 4 A preferred embodiment of the present invention provides a method for adding water to a semi-submersible barge 1, which includes a semi-submersible barge 1, such as... Figure 1 As shown, the semi-submersible barge 1 includes a loading deck 11 and four towers located at the top corners of the loading deck 11: a port bow tower 12, a starboard bow tower 13, a port stern tower 14, and a starboard stern tower 15. The bottom of the semi-submersible barge 1 is equipped with multiple semi-submersible barge ballast tanks 16 and multiple pump rooms 17, with seawater tanks 18 opened within each pump room 17. The process includes the following steps:

[0030] S1: Construct a first seawater steel pipe 3 and a second seawater steel pipe 4. The first seawater steel pipe 3 is fixed to the outside of the left bow tower 12 by a first bracket, and the second seawater steel pipe 4 is fixed to the outside of the right stern tower 15 by a second bracket; or, the first seawater steel pipe 3 is fixed to the outside of the left stern tower 14 by a first bracket, and the second seawater steel pipe 4 is fixed to the outside of the right bow tower 13 by a second bracket.

[0031] S2: When the vessel 2 is not loaded with ballast water, the vessel 2 is towed to the loading deck 11 by a ship transfer vehicle. The bottom of the vessel 2 is provided with multiple ship ballast tanks 21.

[0032] S3: As Figure 4 As shown, the bottom end of the first seawater steel pipe 3 is connected to the seawater tank 18 through the first pump body 5, and multiple first filling ports 31 are opened on the first seawater steel pipe 3. The first filling ports 31 are connected to the corresponding ship ballast tanks 21 through the first water filling hoses 7.

[0033] S4: This step is not sequential with step S3, such as... Figure 2 and Figure 4As shown, the bottom end of the second seawater steel pipe 4 is connected to the seawater tank 18 through the second pump body 6, and multiple second filling ports 41 are opened on the second seawater steel pipe 4. The second filling ports 41 are connected to the corresponding ship ballast tanks 21 through the second water filling hoses 8.

[0034] S5: Ballast water is loaded into the corresponding ship ballast tanks 21 through the first pump body 5 and the second pump body 6 respectively.

[0035] Among them, such as Figure 4 As shown, in step S3, a plurality of first filling ports 31 are formed above the top deck 121 of the port bow tower 12 or above the top deck of the port stern tower 14; in step S4, a plurality of second filling ports 41 are formed above the top deck of the starboard bow tower 13 or above the top deck 151 of the starboard stern tower 15.

[0036] According to the water-filling method of the semi-submersible barge 1 of the present invention, the steel pipelines (i.e., the first seawater steel pipe 3 and the second seawater steel pipe 4) are arranged using the original tower structure of the semi-submersible barge 1. Since both the first seawater steel pipe 3 and the second seawater steel pipe 4 are equipped with multiple filling ports, these ports are quickly connected to the ship's ballast tanks 21 via water-filling hoses. Ballast water is then pumped from the seawater tank 18 of the semi-submersible barge 1 into the corresponding ship's ballast tanks 21 (it should be noted that, as...). Figure 2 As shown, the vessel 2 is equipped with a ballast water inlet 22 for the second water supply hose 8. Compared to the existing technology that uses a single water supply path for water supply, this optimized pipeline layout reduces losses and improves water supply efficiency, shortening the water supply cycle and meeting production plan requirements. Furthermore, as... Figure 4 As shown, since the first seawater steel pipe 3 and the second seawater steel pipe 4 are respectively installed on the bow tower and the stern tower and are arranged diagonally, it is convenient for the ship 2 to be launched from either bow or stern without affecting the normal operation of the semi-submersible barge 1, and it is convenient for fixed-position management.

[0037] It should be noted that, in this embodiment, as Figure 4 As shown, the number of the first filling port 31 and the number of the second filling port 41 are both preferably 5; the first water filling hose 7 and the second water filling hose 8 are both suction hoses wound with wear-resistant rubber and steel wire, which can effectively reduce bending and wear, reduce leakage points, meet the normal design flow requirements, and reduce replacement and extend service life.

[0038] For example, to facilitate the connection and disconnection of pipes, the first filling port 31 is provided with a first flange-type hydraulic connector for connecting the first water filling hose 7; the second filling port 41 is provided with a second flange-type hydraulic connector for connecting the second water filling hose 8. Further, this embodiment also includes a first flange blind plate for covering the first filling port 31 and a second flange blind plate for covering the second filling port 41; when water is not needed, the first flange blind plate can be connected to the first flange-type hydraulic connector, and the second flange blind plate can be connected to the second flange-type hydraulic connector.

[0039] For example, the first pump body 5 has a first filter at its inlet and a first manual butterfly valve at its outlet; the second pump body 6 has a second filter at its inlet and a second manual butterfly valve at its outlet. Thus, the first and second filters prevent impurities from entering the equipment of the vessel 2 during water filling, thereby preventing malfunction and damage to the equipment; the first and second manual butterfly valves facilitate the control of seawater inflow and outflow.

[0040] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0041] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
