Description

Technical Field

[0001] The invention belongs to the technical field of offshore floating bodies, and more specifically, relates to an offshore floating body top-to-bottom alignment device. The invention also relates to a centering method for the offshore floating body top-to-bottom alignment device. Background Art

[0002] Large transport ships such as deck transport ships and ro-ro passenger ships generally have to unload equipment or materials at the dock, but the number of domestic deep-water docks is limited, which affects the timely unloading of equipment and materials of large transport ships, and cannot meet the needs of temporary mobile unloading operations of large transport ships under special circumstances. Under the condition of no dock, the unloading of equipment and materials of transport ships is generally achieved by transferring between transport ships and transfer platforms or building temporary transfer docks. Transport ships usually adopt "side leaning" or "top leaning" to connect with transfer platforms. Because they are far away from the coast and are greatly affected by sea waves, side leaning or top leaning between ships is difficult, inefficient, and the connection stability and reliability are poor. At present, the technology of connecting and unloading equipment and materials by side leaning and top leaning between ships in open sea areas is still immature. The defects of the existing technology are: at present, the berthing connection between ships generally adopts the direct top leaning method. After the top leaning positioning, the relative displacement between the two ships is large, the shaking is serious when the gangway is overlapped, and the safety hazard is large. The collision between the two ships causes great damage to the ship structure; the foreign articulated joint connection technology is adopted, which is inconvenient to operate and has low operating efficiency.

[0003] In the prior art, there is a technology named "Offshore Floating Body Position Self-positioning Device" and the publication (announcement) number is "CN213125871U". This technology relates to the field of floating body technology and discloses an offshore floating body position self-positioning device, including a shell, a first groove is provided inside the shell, a second groove is provided inside the shell and is located on the left side of the first groove, a shock absorbing spring is fixedly connected to the top wall of the inner cavity of the first groove, and four shock absorbing pads are fixedly connected to the bottom wall of the inner cavity of the first groove, and the tops of the four shock absorbing pads are fixedly connected to the equipment box. The offshore floating body position self-positioning device is provided with a charging box inside the shell, and the shell floats on the sea. Under the action of waves, the charging box, the limit seat, the support rod, the fixed ear and the piezoelectric ceramic sheet will shake continuously with the shell. Under the action of inertia, the relative positions of the movable block and the pressure block with the piezoelectric ceramic sheet change, and the pressure block will squeeze the piezoelectric ceramic sheet. The piezoelectric ceramic sheet will generate electrical energy after being deformed by external force, thereby having the effect of power generation. However, this technology does not involve the technical problems and technical solutions of the present application. Summary of the invention

[0014] The first floating body is a transport floating body, and the second floating body is a docking floating body. The transport floating body is mainly a transport ship, and the second floating body is mainly a pier ferry or a deck barge.

[0015] The present invention also relates to a method for centering an offshore floating body against positioning device, which has a simple structure, fast operation, and reliable connection, and can be used for operations under complex, changeable, and severe sea conditions.

A centering groove is arranged on the front side of the leaning structure body, and the centering arm includes a top plate, a seat plate, a panel, and a side plate. The top plate, the seat plate, the panel, and the side plates form a protruding structure for clamping with the centering groove. When the second buoy is berthed, the second buoy (which can be a transfer platform) is aligned with the buoy structure of the first buoy (which can be a transport ship) through the centering arm. After alignment, the mooring cables are retracted to center and approach the first buoy and the second buoy. The cables are tightened and fastened. Then, a channel gangway is overlapped between the two buoys, and the channel gangway is limited and fixed. The equipment and materials are unloaded or transferred between the two buoys through the channel gangway. The principle of the buoy structure of the present invention is mainly based on mechanical buffering and energy absorption.

[0041] The present invention also relates to a method for centering an offshore floating body against positioning device, which has simple steps, fast operation, reliable connection, can be used for operations under complex and changeable and severe sea conditions, can be reliably used for stable abutment between two floating bodies at sea, can meet the need for ships to overcome the influence of wind and waves and perform rapid and reliable abutment when far away from the coast, and can effectively prevent the floating bodies from colliding with each other, protect the floating body structure from damage, and realize the function of large transport ships to quickly and maneuverably unload equipment and materials. The centering steps of the method for centering an offshore floating body against positioning device are as follows:

[0042] S1: When the transport buoy delivers materials and equipment to a certain area and there is no dedicated dock to unload and transfer the materials, the transport buoy is anchored and positioned in a certain sea area and then docked;

[0043] S2: When the docking buoy sails to the anchoring position close to the transport buoy, the docking buoy adjusts its course to be perpendicular to the transport ship buoy. When the two buoys are close to each other, the mooring is done by dropping the cable;

[0044] S3: Relying on the power of the docking buoy and the mooring force of the cable to adjust the position, the centering arm of the docking buoy is inserted into the centering groove of the transport buoy, and the cable is tightened to fix the relative position of the two buoys;

[0045] S4: A gangplank is set up between the transport buoy and the docking buoy to form a roll-on / roll-off channel, so that the docking buoy can sail back and forth and reach the beach to transport equipment and materials.

Centering arm: It is welded from steel plates and profiles. The overall structure is designed in the shape of an airfoil, which reduces its own structural stress and reduces the impact of rigid collision when the ships are aligned. The main components include the top plate, seat plate, seat plate ribs, top plate ribs, panels, side plates, etc. Top plate: The arc-shaped design reduces stress and collision effects and is in direct contact with the top structure of the docked ship. Seat plate, panel, and side plates: They jointly support the top plate and transfer the berthing impact force to the top structure. Seat plate ribs and top plate ribs: The structure is strengthened to improve the overall strength and rigidity of the centering arm. The centering arm is welded and installed on the berthing ship, forming a pair of connectable bodies (top device) with the top structure of the docked ship. When the two ships are positioned, the top device is aligned in a slot-type manner. The floating bodies are initially positioned through the top device, and then the positions of the two floating bodies are fixed with the cable fastening. The present invention proposes a method for aligning a leaning device for stably leaning two floating bodies at sea. Two berthed ships are connected by the leaning device. After the leaning device is installed on the two ships, the mutual impact force of the two ships is mitigated and absorbed. At the same time, the wing-shaped centering arm and the corresponding groove are used for centering, so that the two ships can be stably leaned against each other, thereby realizing the function of unloading or transferring equipment and materials between transport ships.

[0047] In the structure of the present invention, as shown in the attached Figure 6 As shown, Example 1: The docking buoy is a pier ferry, and the buoy width is 7 to 10 meters. For this type of ship, a pair of centering arms are added to the docking buoy and a pair of supporting structures are added to the transport buoy to realize the roll-on and roll-off of equipment. In summary, the beneficial effects of the present invention are: 1. Under the condition of no dock in open sea areas, the unloading and transshipment requirements of equipment and materials between buoys are realized. 2. The operation is quick and the connection is reliable when the buoys are aligned with each other, which greatly shortens the time for the supporting operation and the setting up of the unloading channel. 3. Compared with the conventional articulated joint connection form, the device of the present invention is less affected by external forces and has higher safety. 4. The supporting device of the present invention has a simple structure and is suitable for installation on various types of transport ships, which is conducive to the promotion and application of the device.
