Description

Technical Field

[0001] This application relates to the field of shipbuilding technology, and in particular to a method for simultaneously commissioning multiple roll-on / roll-off equipment. Background Technology

[0002] The roll-on / roll-off (Ro-Ro) equipment on car carriers typically uses a hydraulic system as its driving force. The hydraulic pump station transmits hydraulic energy to actuators such as cylinders and winches through hydraulic pipelines and operating valve blocks, enabling the Ro-Ro equipment, such as ramps and movable decks, to complete the corresponding actions.

[0003] In shipbuilding and construction, a common commissioning method involves using temporary hatch opening pumps and hose fittings to test individual ramps. After commissioning one ramp, the pump and fittings are moved to other ramps for further testing. For car carriers with multiple ramps and movable decks, this method requires repeated transfers of the pumps and disconnection / reconnection of the hose fittings, resulting in a long commissioning cycle, significant fuel consumption, and substantial labor costs. Furthermore, continuous use of the pumps for extended periods can lead to overheating and shutdown, and frequent hose disconnections / reconnections increase the risk of dust and particles entering the hydraulic system. If multiple pumps are installed on board for commissioning, each pump requires refueling, further increasing fuel consumption and the safety risks associated with storing fuel and equipment on board.

[0004] Another existing commissioning method is to wait for the marine hydraulic system, hydraulic pump station, hydraulic pipelines, and operating valve blocks to be installed before using the marine hydraulic unit to commission the roll-on / roll-off equipment. However, the installation, testing, and oil connection of the entire ship's hydraulic system takes a long time, and the installation and commissioning of the roll-on / roll-off equipment may not be able to keep up with the shipbuilding schedule; moreover, when a large number of roll-on / roll-off equipment are commissioned at the same time, a large amount of labor needs to be invested simultaneously. Summary of the Invention

[0005] Therefore, it is necessary to provide a method for simultaneously commissioning multiple roll-on / roll-off (Ro-Ro) devices, which can solve the problem that a single temporary opening pump cannot simultaneously control and commission multiple Ro-Ro devices.

[0006] To solve the above-mentioned technical problems, this application provides the following technical solution: A method for simultaneously commissioning multiple roll-on / roll-off equipment includes the following steps: S1: Identify two or more roll-on / roll-off devices to be debugged and the corresponding operating valve blocks for each roll-on / roll-off device; S2: Connect the temporary hatch opening pump to the oil drum tooling, and install a water tank for heat dissipation at the temporary hatch opening pump; S3: According to the arrangement of the hatch opening pump, the oil drum fixture is connected to each of the operating valve blocks through multiple hose fixtures; S4: Start the temporary hatch opening pump to deliver hydraulic oil through the oil drum fixture and the hose fixture to each of the operating valve blocks; and S5: Operate each of the aforementioned operating valve blocks to drive the cylinder or winch of the corresponding roll-on / roll-off equipment to be debugged, thereby debugging the multiple roll-on / roll-off equipment to be debugged.

[0007] Understandably, by setting up a hydraulic drum fixture as a hub for hydraulic oil transfer and distribution, and using multiple hose fixtures to connect to the operating valve blocks of each roll-on / roll-off equipment to be commissioned, a centralized temporary hydraulic oil supply network of "one pump to multiple devices" is constructed. This allows the same temporary hatch opening pump to simultaneously provide hydraulic energy to multiple ramps and / or movable decks distributed in different locations on the ship. Commissioning personnel only need to operate each operating valve block sequentially to complete the commissioning of multiple devices, eliminating the need to repeatedly move the hatch opening pump and disconnect and reconnect hoses after each device is commissioned. This significantly reduces auxiliary operation time and greatly improves commissioning efficiency.

[0008] In one embodiment, the water tank is configured to cool the temporary hatch opening pump and the hydraulic oil it outputs, thereby extending the continuous operating time of the temporary hatch opening pump.

[0009] In one embodiment, the oil drum fixture is used to receive hydraulic oil supplied to the temporary hatch opening pump and is connected to the suction side of the temporary hatch opening pump.

[0010] In one embodiment, one end of each hose fixture is connected to the oil supply side of the oil drum fixture, and the other end is connected to one of the operating valve blocks to form a temporary hydraulic oil supply branch corresponding to the roll-on / roll-off equipment to be tested.

[0011] In one embodiment, the temporary hydraulic supply branch is configured to remain connected during the commissioning of the roll-on / roll-off equipment to be commissioned until the commissioning of the corresponding roll-on / roll-off equipment is completed.

[0012] In one embodiment, the hatch opening pump arrangement includes: arranging the temporary hatch opening pump, the oil drum fixture, and the hose fixture according to the positions of the multiple roll-on / roll-off devices to be commissioned on the ship, so that the hose fixture can be connected to the corresponding operating valve block.

[0013] In one embodiment, the operation of each of the operating valve blocks includes: for each roll-on / roll-off equipment to be tested, controlling the corresponding operating valve block to deliver hydraulic energy to the cylinder or winch of the roll-on / roll-off equipment to be tested, so that the roll-on / roll-off equipment to be tested performs a predetermined action.

[0014] In one embodiment, during the commissioning of multiple roll-on / roll-off devices to be commissioned, the water tank is used to continuously dissipate heat from the temporary hatch opening pump, so as to reduce the impact of temperature rise caused by continuous operation on the continuity of commissioning.

[0015] In one embodiment, the roll-on / roll-off equipment to be commissioned includes a ramp and / or a movable deck.

[0016] In one embodiment, the method is used to install and commission multiple roll-on / roll-off devices during the construction of a car carrier, prior to the completion of installation, testing, and oil transfer of the marine hydraulic system.

[0017] Compared to existing technologies, a method for simultaneously commissioning multiple roll-on / roll-off (Ro-Ro) devices utilizes a hydraulic drum fixture as a hydraulic oil transfer and distribution hub, and employs multiple hose fixtures connected to the operating valve blocks of each Ro-Ro device to be commissioned, constructing a centralized temporary hydraulic oil supply network of "one pump to multiple devices." This allows the same temporary hatch opening pump to simultaneously provide hydraulic energy to multiple ramps and / or movable decks distributed in different locations on the ship. Commissioning personnel only need to operate each operating valve block sequentially to complete the commissioning of multiple devices, eliminating the need to repeatedly transfer the hatch opening pump and disconnect and reconnect hoses after each device is commissioned, thereby significantly reducing auxiliary operation time and greatly improving commissioning efficiency.

[0026] The roll-on / roll-off (Ro-Ro) equipment on car carriers typically uses a hydraulic system as its driving force. The hydraulic pump station transmits hydraulic energy to actuators such as cylinders and winches through hydraulic pipelines and operating valve blocks, enabling the Ro-Ro equipment, such as ramps and movable decks, to complete the corresponding actions.

[0027] In shipbuilding and construction, a common commissioning method involves using temporary hatch opening pumps and hose fittings to test individual ramps. After commissioning one ramp, the pump and fittings are moved to other ramps for further testing. For car carriers with multiple ramps and movable decks, this method requires repeated transfers of the pumps and disconnection / reconnection of the hose fittings, resulting in a long commissioning cycle, significant fuel consumption, and substantial labor costs. Furthermore, continuous use of the pumps for extended periods can lead to overheating and shutdown, and frequent hose disconnections / reconnections increase the risk of dust and particles entering the hydraulic system. If multiple pumps are installed on board for commissioning, each pump requires refueling, further increasing fuel consumption and the safety risks associated with storing fuel and equipment on board.

[0028] Another existing commissioning method is to wait for the marine hydraulic system, hydraulic pump station, hydraulic pipelines, and operating valve blocks to be installed before using the marine hydraulic unit to commission the roll-on / roll-off equipment. However, the installation, testing, and oil connection of the entire ship's hydraulic system takes a long time, and the installation and commissioning of the roll-on / roll-off equipment may not be able to keep up with the shipbuilding schedule; moreover, when a large number of roll-on / roll-off equipment are commissioned at the same time, a large amount of labor needs to be invested simultaneously.

[0029] Therefore, it is necessary to provide a method for simultaneously commissioning multiple roll-on / roll-off (Ro-Ro) devices, which can solve the problem that a single temporary opening pump cannot simultaneously control and commission multiple Ro-Ro devices.

[0030] Please see Figure 1 This application provides a method for simultaneously commissioning multiple roll-on / roll-off (Ro-Ro) devices. When the marine hydraulic system has not yet completed all installation work, passed the tightness test, or undergone system oil cross-contamination cleaning, on-site construction conditions often do not allow for the direct driving of the actuators of each Ro-Ro device using the marine hydraulic unit. In this situation, to ensure that the commissioning of the Ro-Ro devices can proceed in coordination with the overall shipbuilding schedule and to avoid delays due to waiting for the hydraulic system to be completed, temporary hydraulic power equipment is needed to perform post-installation operational commissioning of multiple Ro-Ro devices.

[0031] Based on the above application scenario, this implementation method first selects two or more roll-on / roll-off (Ro-Ro) devices that need to be installed and debugged from the multiple Ro-Ro devices that have been mechanically installed and positioned throughout the ship, according to the ship's construction plan and actual on-site working conditions, and identifies them as Ro-Ro devices to be debugged.

[0032] In the specific implementation process, the number and specific type of roll-on / roll-off (Ro-Ro) equipment to be tested can be flexibly determined according to the ship's design drawings, deck layout, and construction progress. In this embodiment, the Ro-Ro equipment to be tested may include one or more of ramps and movable decks. Ramps, as key passageways for vehicles to travel between different decks of the ship, typically include bow ramps, stern ramps, and internal connecting ramps, etc., and their operation is generally driven by hydraulic cylinders to achieve ramp extension, retraction, and locking. Movable decks, as movable platforms for adjusting the loading height of each deck, are typically driven by hydraulic winches or hydraulic cylinders for lifting and locking. The Ro-Ro equipment to be tested is not limited to ramps and movable decks; in other embodiments, other Ro-Ro equipment driven by hydraulic actuators may be included in the testing scope according to the specific ship type requirements.

[0033] Each roll-on / roll-off (Ro-Ro) equipment to be tested is equipped with an operating valve block 4. This operating valve block 4 is installed on the hydraulic pipeline near the Ro-Ro equipment or is centrally located within a valve block 4 box on the ship. As the core component for hydraulic energy distribution and control, the operating valve block 4 controls the direction, speed, and start / stop of the hydraulic actuator of the corresponding Ro-Ro equipment. Depending on the equipment type and drive method, the hydraulic actuator of each Ro-Ro equipment to be tested can be a hydraulic cylinder or a hydraulic winch.

[0034] In some embodiments, the ramp's extension and retraction are typically performed by one or more hydraulic cylinders located at the ramp's pivot point. The expansion and contraction of the cylinder piston rods enable the ramp to unfold and retract. The raising, lowering, and locking of the movable deck may be achieved by a hydraulic winch in conjunction with wire ropes or chains, or by direct actuation by vertically arranged hydraulic cylinders. Under normal operating conditions, these hydraulic actuators require hydraulic oil with a certain pressure and flow rate supplied by a hydraulic pump station through a pipeline system, and are controlled by corresponding operating valve blocks 4 to achieve predetermined actions.

[0035] After determining the roll-on / roll-off (Ro-Ro) equipment to be tested and its corresponding operating valve block 4, the first step is to formulate a layout plan for the hatch opening pump 1 based on the actual distribution of the multiple Ro-Ro equipment to be tested on the ship. As mentioned earlier, the Ro-Ro equipment on the ship is distributed in different areas on different decks. For example, the bow ramp is usually located at the bow of the ship, the stern ramp at the stern, and the movable decks are distributed in different longitudinal and transverse positions on each cargo hold deck. The formulation of the hatch opening pump 1 layout plan needs to comprehensively consider the feasibility of placing the temporary hatch opening pump 1, the placement space of the oil drum fixture 3, the direction and length limitations of each hose fixture 2, as well as on-site construction access and operational safety factors. Specifically, the hatch opening pump 1 layout plan includes: rationally selecting the placement positions of the temporary hatch opening pump 1 and the oil drum fixture 3 based on the location of the multiple Ro-Ro equipment to be tested on the ship, and planning the laying paths of each hose fixture 2 so that each hose fixture 2 can extend from the oil outlet end of the oil drum fixture 3 to the operating valve block 4 of the corresponding Ro-Ro equipment to be tested.

[0036] In a specific embodiment, to shorten the laying length of the hose fixture 2 and reduce pressure loss along the way, the temporary hatch opening pump 1 and the hydraulic drum fixture 3 are arranged near the geometric center of multiple roll-on / roll-off equipment to be commissioned or close to areas with dense equipment distribution. When multiple roll-on / roll-off equipment to be commissioned are concentrated in adjacent several active deck areas, the temporary hatch opening pump 1 and the hydraulic drum fixture 3 can be temporarily placed in an open area on the deck near that area, with necessary fixing and protection measures taken. The hydraulic drum fixture 3 is connected to the temporary hatch opening pump 1 via a pipeline. The hydraulic drum fixture 3 is used to contain the hydraulic oil supplied to the temporary hatch opening pump 1. The suction side of the temporary hatch opening pump 1 is connected to the supply side of the hydraulic drum fixture 3 to form a stable oil supply relationship, ensuring that the temporary hatch opening pump 1 can continuously obtain a sufficient amount of clean hydraulic oil during operation.

[0037] After the temporary hatch opening pump 1 and the oil drum fixture 3 are arranged and positioned, the connection work of the hose fixture 2 is carried out. After passing through the oil drum fixture 3, the oil supply side of the temporary hatch opening pump 1 forms multiple independent temporary hydraulic oil supply branches through multiple hose fixtures 2.

[0038] Specifically, one end of each hose fixture 2 is connected to the oil supply side of the oil drum fixture 3, and the other end is connected to the oil inlet of the operating valve block 4 of a roll-on / roll-off equipment to be tested. Each hose fixture 2 independently forms a temporary hydraulic oil supply branch corresponding to the roll-on / roll-off equipment to be tested. Through the above connection method, the hydraulic oil output by the temporary hatch opening pump 1 is diverted through the oil drum fixture 3 to each hose fixture 2, and then delivered to each operating valve block 4, so that the operating valve block 4 of each roll-on / roll-off equipment to be tested receives hydraulic energy from the same temporary hatch opening pump 1. In this way, each roll-on / roll-off equipment to be tested has an independent temporary oil supply path at its corresponding operating valve block 4. The commissioning personnel can operate the operating valve blocks 4 of different roll-on / roll-off equipment to be tested according to the commissioning sequence while the same temporary hatch opening pump 1 is running continuously, so as to drive the corresponding oil cylinder or winch to move, without having to immediately disassemble the hose and move the hatch opening pump 1 to the next equipment after each piece of equipment is commissioned, thus providing a hydraulic connection basis for subsequent centralized commissioning operations.

[0039] After completing the arrangement and connection of the temporary hatch opening pump 1, the oil drum fixture 3, and the multiple hose fixtures 2, a water tank is added to the temporary hatch opening pump 1. The water tank is specifically installed in a position adjacent to the temporary hatch opening pump 1 and connected to the cooling water chamber of the temporary hatch opening pump 1 through a water pipeline. In some embodiments, the circulating water of the water tank can also be led to the vicinity of the oil outlet pipeline of the temporary hatch opening pump 1 to dissipate heat from the pump body and the hydraulic oil output by utilizing the principle of heat exchange.

[0040] During the operation of the temporary hatch opening pump 1, hydraulic oil is drawn into the pump 1 through the oil drum fixture 3 and then pressurized and output by the pump 1. During the hydraulic energy transfer process, some mechanical energy is converted into heat energy, causing the hydraulic oil temperature to gradually rise. At the same time, the motor and pump body of the hatch opening pump 1 also generate heat during operation. If the heat cannot be dissipated in time, the continuous rise in hydraulic oil temperature will lead to a decrease in oil viscosity, reduced lubrication performance, and accelerated aging of seals. In severe cases, it may even cause accelerated wear of internal components of the hatch opening pump 1 or even malfunction and shutdown, thus interrupting the commissioning operation. The water tank is designed to solve the above problems.

[0041] The water tank provides continuous cooling for the temporary hatch opening pump 1 and the circulating hydraulic oil. Specifically, the water tank stores cooling water, and the casing of the temporary hatch opening pump 1 is equipped with a cooling jacket or cooling coil. Driven by the pump, the cooling water flows through the cooling jacket or coil, carrying away the heat generated by the operation of the temporary hatch opening pump 1 and cooling the pump body. At the same time, when the hydraulic oil flows through the oil cooler connected to the water tank after being output from the temporary hatch opening pump 1, some of the heat in the oil is transferred to the cooling water through oil-water heat exchange, thereby reducing the temperature of the hydraulic oil. Through the above heat dissipation mechanism, the possibility of the temporary hatch opening pump 1 affecting the continuity of commissioning due to temperature rise caused by continuous operation can be effectively reduced, and commissioning interruptions and repeated restarts caused by high-temperature protection shutdowns can be avoided.

[0042] For tasks requiring continuous commissioning of multiple roll-on / roll-off (Ro-Ro) equipment, the temporary hatch opening pump 1 often needs to run continuously for extended periods throughout the commissioning process. This is especially true when there are many Ro-Ro equipment units to be commissioned and the commissioning procedures for each unit are time-consuming; the continuous operation time of the hatch opening pump 1 can reach several hours or even longer. In such continuous multi-equipment commissioning tasks, the cooling function of the water tank can be kept active throughout the commissioning process, ensuring continuous circulation of cooling water to remove heat from the hatch opening pump 1 and hydraulic oil. Compared to the conventional temporary hatch opening pump 1 commissioning method without a water tank, the addition of a water tank significantly extends the continuous operating time of the hatch opening pump 1. Commissioning personnel no longer need to frequently interrupt commissioning to wait for the equipment to cool down due to high temperature shutdowns of the hatch opening pump 1, thus effectively improving the commissioning efficiency per unit time.

[0043] After completing all the above connections and heat dissipation configurations, start the temporary hatch opening pump 1. After the temporary hatch opening pump 1 starts, its suction side draws clean hydraulic oil from the oil drum fixture 3. After being pressurized by the hatch opening pump 1, the hydraulic oil is output from the supply side and first enters the supply side chamber of the oil drum fixture 3. Since the supply side of the oil drum fixture 3 is simultaneously connected to multiple hose fixtures 2, the hydraulic oil is distributed to each hose fixture 2 under the action of the diverter block inside the oil drum fixture 3 or at the outlet of the oil drum fixture 3. Then, it is delivered to the oil inlet of the corresponding operating valve block 4 of each roll-on / roll-off equipment to be debugged through each hose fixture 2, thereby establishing a complete hydraulic oil supply path from the temporary hatch opening pump 1 to each operating valve block 4.

[0044] At this point, hydraulic oil with predetermined pressure and flow rate has been supplied to the inlet of each operating valve block 4. The commissioning personnel can then operate the corresponding operating valve block 4 for each roll-on / roll-off equipment to be commissioned. The operating valve block 4 typically includes a manual directional valve or a solenoid directional valve. The commissioning personnel switch the internal oil circuit of the valve block 4 by moving the valve stem or triggering the solenoid, allowing hydraulic oil to enter the hydraulic actuator of the roll-on / roll-off equipment to be commissioned through the corresponding working port of the valve block 4.

[0045] For ramps, hydraulic oil enters the rodless or rod chamber of the cylinder that drives the ramp's extension and retraction, pushing the piston rod to extend or retract, thus enabling the ramp to unfold or retract. For movable decks, hydraulic oil enters the winch hydraulic motor or lifting cylinder that drives the deck's raising and lowering, causing the movable deck to rise or fall to a predetermined position. Through the above operations, the cylinders or winches of each roll-on / roll-off equipment to be tested can be driven sequentially or alternately as needed for on-site commissioning, completing the testing of various commissioning items such as the operational flexibility, stroke range, locking function, and sealing performance of each roll-on / roll-off equipment.

[0046] Since multiple operating valve blocks 4 are all connected to a temporary hydraulic oil supply path consisting of the same temporary hatch opening pump 1 and oil drum fixture 3 via corresponding hose fixtures 2, a centralized hydraulic oil supply network of "one hatch opening pump 1, one oil drum fixture 3, multiple hose fixtures 2, and multiple operating valve blocks 4" is formed at the commissioning site. Under this network architecture, commissioning personnel do not need to immediately perform complicated operations such as transferring the hatch opening pump 1, disassembling the hose fixtures 2, and reconnecting them to the next piece of equipment after each piece of equipment is commissioned. Instead, they can sequentially commission multiple roll-on / roll-off equipment to be commissioned simply by switching the working states of different operating valve blocks 4, while maintaining the existing connections between each hose fixture 2 and the corresponding operating valve block 4.

[0047] Once all commissioning items for a particular roll-on / roll-off (Ro-Ro) equipment have been completed, its corresponding hose fixture 2 can remain connected without immediate removal until all commissioning work for all Ro-Ro equipment is completed, at which point the pipelines will be uniformly dismantled, cleaned, and recycled. This significantly reduces the frequency of repeated hose disconnections and reconnections on-site, lowering the risk of joint wear, seal failure, and external dust particles entering the hydraulic system due to frequent disconnections and reconnections. Furthermore, it significantly shortens the auxiliary operation time during equipment switchover, allowing the temporary hatch opening pump 1 to dedicate more of its effective working time to performing actual Ro-Ro equipment operation commissioning, thereby improving overall commissioning efficiency and resource utilization.

[0048] After completing the connection and arrangement of the temporary hatch opening pump 1, oil drum fixture 3, water tank and multiple hose fixtures 2 according to the aforementioned steps, the commissioning personnel first connected the operating valve blocks 4 corresponding to the multiple roll-on / roll-off equipment to be commissioned to their respective temporary hydraulic oil supply branches.

[0049] Specifically, for the selected ramps to be commissioned, the commissioning personnel connected and tightened the oil inlet of the corresponding operating valve block 4 of each ramp to the end connector of a hose fixture 2. Similarly, for the selected movable decks to be commissioned, their corresponding operating valve blocks 4 were connected to the oil supply side of the oil drum fixture 3 via their respective hose fixtures 2. During the connection process, the commissioning personnel needed to check the reliability and sealing of each connector to ensure that the connection between each hose fixture 2 and the operating valve block 4 was secure and leak-free. After all the operating valve blocks 4 corresponding to the roll-on / roll-off equipment to be commissioned were connected, the temporary hydraulic oil supply branch network was completed.

[0050] Subsequently, the commissioning personnel operated each operating valve block 4 in sequence according to the on-site commissioning arrangements. In some embodiments, the commissioning personnel first operated the operating valve block 4 corresponding to the first roll-on / roll-off equipment to be commissioned. By switching the working position of the valve block 4, the hydraulic oil entered the bow ramp drive cylinder through the operating valve block 4, driving the cylinder piston rod to perform the extension or retraction action, thereby driving the bow ramp to complete the deployment and retraction actions.

[0051] During operation, the commissioning personnel observe whether the ramp moves smoothly, whether there is any jamming or abnormal noise, check whether the ramp can be reliably locked at its limit position, and record the relevant operating parameters. After completing all the scheduled commissioning items for the ramp, the commissioning personnel return the operating valve block 4 to the neutral position, putting the oil supply branch into standby mode.

[0052] At this time, since the hose tool 2 corresponding to the bow ramp remains connected to the operating valve block 4 throughout the entire commissioning process, the commissioning personnel do not need to perform any pipe disassembly or pump relocation operations. They can directly move to the operating valve block 4 corresponding to the next roll-on / roll-off equipment to be commissioned and commission the lifting and lowering action of the movable deck.

[0053] Similarly, the commissioning personnel can operate the operating valve block 4 of each roll-on / roll-off equipment to be commissioned one by one under the stable commissioning conditions of continuous operation of the same temporary hatch opening pump 1, continuous oil supply of the same oil drum tool 3, and continuous heat dissipation of the same water tank, so that the oil cylinder or winch of the corresponding roll-on / roll-off equipment can execute their respective predetermined action sequences in sequence.

[0054] After all the commissioning items of a roll-on / roll-off equipment to be commissioned are completed, the corresponding hose fixture 2 is not immediately removed, but continues to be connected to the oil drum fixture 3 and the operating valve block 4 until all the commissioning work of the roll-on / roll-off equipment to be commissioned is completed.

[0055] The reason for adopting this operational strategy of "not immediately disconnecting the hose after commissioning and maintaining the connection until all is completed" is that in scenarios where multiple roll-on / roll-off devices are being commissioned simultaneously, even if the hydraulic power supply to the corresponding oil supply branch is temporarily no longer needed after the commissioning of a certain device, keeping the hose fixture 2 connected will not have any negative impact on the commissioning of other devices. Simply placing the corresponding operating valve block 4 in the neutral position or closing the shut-off valve of that branch will cut off the hydraulic oil flow in that branch without affecting the normal oil supply to other oil supply branches. Under these conditions, keeping the hose fixture 2 connected not only avoids the manpower consumption and joint wear caused by repeated on-site disassembly and reassembly, but more importantly, it reduces the chance of introducing dust, particles, and other contaminants due to repeated disassembly and reassembly operations, thus maintaining the cleanliness of the hydraulic system.

[0056] Once all the roll-on / roll-off (Ro-Ro) equipment to be commissioned has been completed, the commissioning personnel can then uniformly disconnect the connections between each hose fixture 2 and the operating valve block 4, and retrieve the temporary hatch opening pump 1, hydraulic drum fixture 3, water tank, and each hose fixture 2 to the designated storage location. Throughout the entire commissioning process, the remaining Ro-Ro equipment that has not yet been commissioned or is currently being commissioned operates under the same set of commissioning conditions, namely, hydraulic power is provided by the same temporary hatch opening pump 1, hydraulic oil is stored and supplied by the same hydraulic drum fixture 3, and the same water tank continuously cools the hatch opening pump 1 and the hydraulic oil. This centralized and unified hydraulic energy supply method ensures the consistency and repeatability of hydraulic parameters during the commissioning of each piece of equipment, which is beneficial for horizontal comparison of commissioning results and troubleshooting.

[0057] In the above embodiment, the temporary hatch opening pump 1, the oil drum fixture 3, the multiple hose fixture 2, and the water tank together constitute a temporary hydraulic commissioning configuration for centralized commissioning of multiple devices. The core advantage of this configuration is that it exists completely independently of the ship's fixed marine hydraulic system. In the traditional shipbuilding process, the hydraulic commissioning of roll-on / roll-off (Ro-Ro) equipment usually requires waiting for the installation of all pipelines in the ship's hydraulic system, the passing of the tightness test, the completion of the oil flushing, and the completion of the overall system integration before the marine hydraulic unit can be used to commission the Ro-Ro equipment. However, the ship's hydraulic system covers a wide range, involves many components, and has complex pipeline layout. Its installation, tightness test, and oil flushing cycle often last for several weeks or even months. If the commissioning of Ro-Ro equipment depends entirely on the completion progress of the marine hydraulic system, it will inevitably delay the commissioning window after the installation of Ro-Ro equipment, thereby affecting the smooth progress of subsequent processes such as cabin insulation, interior decoration installation, and deck covering, ultimately restricting the overall construction cycle of the ship.

[0058] The temporary hydraulic commissioning configuration provided in this embodiment does not require waiting for the overall completion of the marine hydraulic system. It can independently and simultaneously provide the necessary clean hydraulic energy for commissioning multiple roll-on / roll-off (Ro-Ro) devices distributed across different deck areas, even before the marine hydraulic system has completed installation, testing, and oil transfer during the construction phase. This not only allows the installation and commissioning of Ro-Ro devices to proceed in parallel with hull construction and system installation, effectively shortening the operation time on the critical path, but also provides greater flexibility and buffer space for overall control of the shipbuilding schedule. Furthermore, because this configuration uses a centralized commissioning mode where one set of equipment serves multiple Ro-Ro devices, compared to configuring a temporary hatch opening pump 1 for each Ro-Ro device individually or transferring and commissioning them one by one, it significantly optimizes the number of equipment deployed, total fuel consumption, and on-site space occupation. It is a Ro-Ro device commissioning solution that combines high efficiency, economy, and safety.

[0059] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0060] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application.
