[0042] Undoubtedly, in cross-sea island landing operations, fuel supply is an important part of the logistics support for cross-sea island capture operations. In wartime, the enemy will certainly implement port closure and port destruction operations, and our army is very likely to face an unfavorable situation where there are no ports or docks available. Under the condition that there are no ports or docks on the enemy shore, organizing the transfer of fuel from the shore to the sea without docks is an essential means for the logistics oil and gas forces of the campaign to implement shore and beach fuel supply.

[0043] Civilian oil tankers are very abundant, and they can make up for the lack of standard oil tankers. Therefore, it is necessary to modify them appropriately to meet the requirements of oil unloading in high sea conditions without available port terminals.

[0044] In this application, the applicant believes that it can be modified to build a high sea condition oil unloading system. In this way, the unloading system can fill the gap of insufficient standard equipment, greatly improve the oil support capability for large-scale landing operations, and greatly reduce the manufacturing cost and maintenance cost of oil unloading equipment, thus having extremely high economic and military value.

[0045] Therefore, it is of great significance to use civilian ships to build a sea-to-shore oil unloading channel that can adapt to high sea conditions, has good maneuverability and large transportation flow, so as to provide uninterrupted oil replenishment for the logistics and oil forces of the cross-sea island-capturing combat cluster.

[0046] There are some attempts in the prior art, such as rapid construction of a modular oil delivery system using a barge carrier.

[0047] The system is mainly composed of a self-propelled deck barge and a product oil tanker. However, the mooring method of the product oil tanker is four-point mooring. Therefore, it is difficult to apply it to civilian oil tankers. Because civilian oil tankers themselves do not have the mooring equipment required for four-point mooring. Moreover, even if the civilian oil tankers are modified with mooring equipment, due to their own poor operating performance, it will take a long time to throw the four-point mooring.

[0048] In addition, the four-point mooring has limited adaptability to sea conditions. If you want to moor an oil tanker in high sea conditions, you need to increase the size of the anchor chain, cable and anchor in the mooring system, which is not conducive to wartime operations.

[0049] In addition, another problem with the above solutions is that the oil unloading technology from sea to shore all adopts a floating pipeline system. That is, the oil pipeline floats on the sea surface, so the oil pipeline is greatly affected by wave currents. In addition, the working pressure and tensile strength of the oil hose are limited, so the ability of the entire system to adapt to sea conditions and oil transportation distance is very limited.

[0050] In order to overcome the above defects and make full use of civilian ships to transport oil from sea to shore under high sea conditions, in this embodiment, the applicant uses civilian ships to construct a high sea condition oil unloading system.

[0051] The system mainly uses a barge and a multi-purpose workboat.

[0052] The barge has been modified to install sea-to-shore oil unloading equipment to build a submarine oil unloading channel that can adapt to high sea conditions.

[0053] The multi-purpose workboat does not need to be modified. It can be used as a tugboat for the integrated anchor base of the oil tanker single-point mooring system. When the oil unloading system is deployed in high sea conditions, it can assist in the deployment of the integrated anchor base to complete the single-point mooring of the oil tanker.

[0054] The details are described below.

[0055] In the embodiment, the high sea condition oil unloading system constructed by using civilian ships includes a self-propelled barge 1 and a multi-purpose work boat.

[0056] The equipment modified on the barge 1 includes a submarine pipeline (submarine oil hose), a retractable guide device assembly 3, an auxiliary operation boat assembly 4, an amphibious operation vehicle assembly 5, a shore mooring device assembly 6 and a power distribution and accessory container 7.

[0057] Among the above components, the submarine pipeline, the retracting and guiding device 3, the auxiliary operation boat assembly 4, the amphibious operation vehicle assembly 5, and the shore mooring device assembly 6 are all fixed on the pallet 9, and the power distribution and accessory container 7 is fixed on the barge deck by welding.

[0058] The retractable guide device assembly 3 is composed of a reel device, a wall frame device, a drive device, a pipe arrangement device, a conduit device, a brake device, a hydraulic system, an electrical control system, etc. It is mainly used for the reeling and retracting of submarine oil hoses.

[0059] The electrical system controls the hydraulic pump station to provide power source, driving the hydraulic motors of the drum device and the pipe laying device to rotate simultaneously. The hydraulic motor of the drum device is decelerated by the reducer and then meshes with the large and small gears to drive the drum to rotate together. At the same time, the hydraulic motor of the pipe laying device drives the bidirectional screw to rotate through the reducer, so that the bell mouth reciprocates back and forth on the guide rod, and the rubber hose is wound neatly and orderly during the unfolding and retracting process.

[0060] The auxiliary work boat assembly 4 consists of a work boat and its deployment and recovery device. The deployment and recovery device is used for deploying and retrieving the work boat on the barge. The work boat is used to assist the multi-purpose work boat in offshore operations and ensure patrols.

[0061] The amphibious operation vehicle assembly 5 consists of an amphibious operation vehicle and its deployment and recovery device. The deployment and recovery device is used for the deployment and recovery of the amphibious operation vehicle on the barge. The amphibious operation vehicle is used to transport shore mooring anchors, shore operation equipment and shore operation personnel ashore.

[0062] The shore mooring device assembly 6 consists of an operating boom, a large holding anchor, a wire rope, a shore mooring joint and a shore operating device, etc. It is used to fix the submarine oil hose after it is brought ashore, forming a complete oil transfer channel from sea to shore to avoid being dragged out to sea by ocean currents.

[0063] The power distribution and accessory container 7 consists of a 20-foot standard container, a power distribution box and an accessory box. The power distribution box is used for distributing electricity to the submarine pipeline retracting and guiding device, the operating boat deploying and recovering device, the amphibious operating vehicle deploying and recovering device and the operating boom, and the accessory box is used for storing spare accessories.

[0064] Multi-purpose workboat 2 is responsible for towing and laying the integrated anchoring base.

[0065] The integrated anchor base is a large steel box-type barge; it consists of a box, outfitting accessories, ballast system, and floating system. It can also further integrate underwater hoses, jumper hoses, swivel joints, mooring buoys, mooring chains and other equipment, so as to meet the needs of single-point mooring system operations for oil tankers in high sea conditions.

[0066] The following will explain the oil unloading system in conjunction with its working process.

[0067] Barge 1 sails to the designated sea area by itself, and deploys its own mooring device to complete stable mooring.

[0068] The auxiliary operation boat 4 is hoisted and launched by the deployment and recovery device to assist the multi-purpose work boat 2 in deploying the single-point mooring system for the oil tanker, while patrolling and keeping watch.

[0069] The amphibious work vehicle 5 is hoisted into the water by the deployment and recovery device, and transports the shore workers and the equipment of the shore mooring device assembly 6 to the shore work point; the shore workers mark the shore terminal deployment point and complete the fixation of the free end of the shore mooring on the shore.

[0070] After the multi-purpose work boat 2 reaches the marked position, the ballasting operation of the integrated anchor base plate 8 is completed and the single-point mooring system of the oil tanker is deployed.

[0071] With the cooperation of the auxiliary operation boat 4 and the amphibious operation vehicle 5, the barge 1 lays the submarine oil pipeline from the terminal position on the shore to the integrated anchor base position of the single-point mooring system, and completes the connection between the submarine hose and the jumper hose after arriving at the designated position.

[0072] After the barge 1 and the multipurpose work boat 2 complete the laying of the submarine oil pipeline and the single-point mooring system for the oil tanker, the oil tanker arrives at the operating location, and the multipurpose work boat 2 assists in completing the single-point mooring of the oil tanker, and connects the floating hose integrated in the integrated anchor base to the oil outlet of the oil tanker, forming an oil pipeline channel from sea to shore.

[0073] After checking that there are no leaks, oil transfer operations can be carried out.
