Description

Technical Field

[0001] This invention relates to the technical field of ship replenishment at sea, and more particularly to an electric-driven dry liquid cargo replenishment and delivery system. Background Technology At-sea replenishment is crucial for maintaining the continuous navigation of ships, with the lateral transfer of heavy dry and liquid cargo being the core and challenging aspect of replenishment operations. To ensure the transfer capacity and efficiency of replenishment operations, it is necessary to design an integrated dry and liquid cargo transfer system that can meet the requirements of both dry and liquid cargo transfer while reducing the footprint required for the replenishment transfer system.

[0002] To facilitate replenishment for both dry and liquid cargo shipments, the most widely used solution currently is to use two independent, parallel sling replenishment systems: one for dry cargo and one for liquid cargo. This solution, due to the requirements of two independent systems, their respective drive units, and storage areas, occupies a significant amount of deck space. Furthermore, this approach cannot achieve rapid switching between dry and liquid cargo, has a lengthy replenishment process, and incurs high maintenance costs.

[0003] Another approach being explored is the hydraulic stabilizing gantry system. However, this system has poor operating range and maneuverability, is highly sensitive to changes in the distance between the two vessels, and has a slow response time. Furthermore, to achieve end-effector compensation, this system requires sophisticated hydraulic servo mechanisms and complex real-time control algorithms, resulting in extremely high manufacturing and maintenance costs.

[0004] Among existing related patent technologies, such as patent document (CN107554704A), a marine integrated replenishment system is disclosed. One of its objectives is to solve the problem of marine integrated replenishment systems occupying a large amount of deck space. However, its solution still has space occupation issues: although the system integrates dry cargo and liquid cargo replenishment systems onto a single gantry, multiple winch devices (dry cargo overhead cable winch, liquid cargo overhead cable winch, lifting winch, external traction cable winch, internal traction cable winch, traction winch, etc.) still need to be installed on the deck. These winches are scattered in different locations on the deck, occupying a large amount of deck operating space. The two column structures and their bottom installation area also require a large amount of deck space; and it cannot achieve… Rapid switching between dry and liquid cargo: When switching from dry cargo replenishment to liquid cargo replenishment, the end of the dry cargo overhead cable connected to the receiving ship needs to be retracted to the lifting pulley device. The cargo transfer trolley then stops at the lifting pulley device, and the lifting pulley device descends along the length of the column. When switching from liquid cargo replenishment to dry cargo replenishment, the end of the liquid cargo overhead cable connected to the receiving ship needs to be retracted to the liquid cargo overhead cable pulley via a liquid cargo overhead cable winch. The pipeline trolley then stops at the liquid cargo overhead cable pulley. This series of operations is time-consuming in the complex maritime environment and cannot meet emergency replenishment needs. Each switch requires readjusting the equipment status, reducing replenishment efficiency. Moreover, the replenishment process is too long and maintenance costs are high. Therefore, although this patent solves the problem of traditional systems occupying deck space to a certain extent, it still has significant shortcomings in terms of rapid switching between dry and liquid cargo, replenishment efficiency, and maintenance costs, making it difficult to meet the demand for high-efficiency, multi-functional maritime replenishment.

[0005] In response to the problems existing in the current technology, there is an urgent need to equip the system with a heavy-duty dry and liquid cargo delivery system that can be widely promoted and applied. This system should be able to meet the needs of heavy-load dry cargo replenishment operations and liquid cargo replenishment operations, improve reliability and maintainability, be feasible to design and manufacture, and enhance safety performance.

[0011] Furthermore, a multi-hook spreader is installed at the bottom of the conveyor trolley assembly for suspending replenishment goods.

[0012] Furthermore, each hook on the multi-hook spreader is equipped with an anti-slip tongue to ensure that the grappling cable will not slip out during the transfer process.

[0013] Furthermore, the center of gravity of the entire conveyor trolley assembly and multi-hook lifting device is located at the lower part of the overhead cable, allowing the crane to move smoothly even when unloaded.

[0014] Furthermore, the heavy-duty liquid cargo delivery system consists of a dual-probe refueling device, a saddle assembly, a tethering assembly, and a piping assembly. The heavy-duty liquid cargo delivery system is suspended on the cross cable via the saddle assembly, and the various hose assemblies are connected through the saddle assembly. The saddle assembly is suspended on the cross cable via a pulley. The saddle assembly is connected to the saddle cable via a shackle. The outer saddle assembly is connected to the outer saddle cable, the middle saddle assembly is connected to the middle saddle cable, and the inner saddle assembly is connected to the inner saddle cable. The saddle cable winch controls the movement of the saddle cable along the cross cable via the saddle cable, thereby controlling the movement of the liquid cargo delivery system along the cross cable.

[0015] Furthermore, the fixed saddle assembly of the heavy-duty liquid cargo delivery system is connected to the fixed pulley via a shackle; the fixed saddle assembly is fixed on the gantry, and the heavy-duty liquid cargo delivery system is hooked onto the gantry via the fixed pulley of the fixed saddle assembly.

[0016] Furthermore, the oil pipeline terminal in the piping system assembly is a probe refueling device, used for docking and matching with the dual oil receiving head receiving device of the receiving vessel, or using the upper probe to dock and match with the single oil receiving head receiving device of the receiving vessel; the water pipeline terminal in the piping system assembly is a hose connector, used for connecting the hose connector of the receiving vessel.

[0017] Compared with the prior art, the present invention has the following significant advantages: 1.

[0024] Furthermore, a multi-hook spreader 26 is installed at the bottom of the conveyor trolley assembly 23 for suspending replenishment goods. Each hook on the multi-hook spreader 26 is equipped with an anti-slip tongue to ensure that the grappling cable will not slip out during the conveying process. The center of gravity of the entire conveyor trolley assembly 23 and the multi-hook spreader 26 is located at the lower part of the overhead cable, allowing the crane to move smoothly even when unloaded.

[0027] Furthermore, the terminal of the oil pipeline system is a probe refueling device 311, which can be connected and matched with the dual oil receiving head receiving device of the receiving vessel, or it can be connected and matched with the single oil receiving head receiving device of the receiving vessel using only the upper probe; the terminal of the water pipeline system is a hose connector 312, which can be connected to the hose connector of the receiving vessel.
