Description

Technical Field

[0001] The present invention relates to the technical field of compensating boarding devices, and in particular to a compensating boarding device for a floating platform. Background Art

[0002] Floating offshore platforms are mostly floating offshore oil platforms or floating offshore wind power platforms. There are currently few of them and most of them operate independently.

[0003] Most of the current wave position compensation boarding devices are located on ships, but the adaptability of ships to floating platforms varies. In addition, due to the limitations of ship type and boarding method, the wave position compensation boarding devices located on ships are not friendly to floating offshore platforms, resulting in many operation and maintenance ships being unable to or having difficulty boarding floating offshore platforms. Summary of the Invention

[0004] In view of this, the present invention provides a floating platform compensating boarding device to solve the problem that existing operation and maintenance vessels have difficulty boarding floating offshore platforms.

[0005] In a first aspect, the present invention provides a floating platform compensating landing device, comprising:

[0006] Wave and position compensation device for fixed installation on the deck of a floating platform;

[0007] a retractable manned boarding device connected to the wave and position compensation device via a fixing and angle adjustment device;

[0008] The retractable manned boarding device comprises:

[0009] Retractable manned platform for docking with operating vessels;

[0010] A manned platform fixing unit is provided at the end of the retractable manned platform and is used to absorb or grasp the ship;

[0011] The protective device is arranged along the retractable manned platform.

[0012] When the floating platform compensation and docking device is in operation, the wave and position compensation device is fixedly installed on the floating platform deck. After activation, it can offset the impact of waves to maintain the stability of the device. The retractable manned boarding device is connected to the compensation device through a fixing and angle adjustment device. It can adjust the angle according to the position of the operating vessel. The retractable manned platform then extends outward to connect with the vessel. The manned platform fixing unit at its end firmly fixes the manned platform to the vessel through adsorption or gripping. At the same time, the protective devices arranged along the platform are synchronously deployed to form a safety protection structure to prevent workers from falling. This working method allows the device to adapt to the docking needs of different ships. Through the stabilizing effect of the compensation device, the flexible connection of the retractable platform, the reliable connection of the fixing unit, and the safety protection of the protective device, it effectively solves the problem of incompatibility between existing operation and maintenance ships and floating platforms, ensuring that workers can travel smoothly and safely between the floating platform and the ship, and improving the convenience and safety of marine operations.

[0013] In an optional embodiment, the wave and position compensation device includes a hydraulic cylinder or a multi-degree-of-freedom motion platform for offsetting the platform displacement caused by waves.

[0014] The wave and position compensation device includes a hydraulic cylinder or a multi-degree-of-freedom motion platform. When waves act on the floating platform, the hydraulic cylinder can sense and offset the platform displacement caused by the waves in real time through the telescopic action of the hydraulic system or the multi-degree-of-freedom motion platform with its multi-directional movement capabilities, and continuously adjust the position and posture of the retractable manned boarding device to keep it stable, ensuring that the retractable manned platform is not affected by wave fluctuations when docking with the operating vessel, providing a smooth boarding path for the operating personnel, effectively solving the problem of unstable boarding caused by waves, and ensuring the safety and reliability of the boarding process.

[0015] In an optional embodiment, the retractable manned platform includes a multi-stage nested telescopic arm.

[0016] In an optional embodiment, the manned platform fixing unit is a vacuum suction cup or a hydraulic mechanical clamp.

[0017] The manned platform's securing unit uses a vacuum suction cup. Its working principle is to draw air from the cup to create negative pressure, allowing it to adhere tightly to flat surfaces such as the deck and bulkhead of the operating vessel. Specifically, the vacuum cup, typically made of rubber or an elastic material, comes into contact with the vessel's surface. A vacuum generator (such as a vacuum pump) activates, rapidly expelling the air from the cup. This creates a pressure differential between the inside and outside of the cup, generating a suction force that secures the manned platform to the vessel.

[0018] Alternatively, the manned platform's securing unit utilizes a hydraulic mechanical clamp, whose core principle is to achieve a rigid clamping of the ship's structure using the driving force of the hydraulic system. Specifically, a hydraulic mechanical clamp typically consists of a hydraulic cylinder, a mechanical arm, and a gripper. When the operating vessel approaches, the hydraulic system activates, and the cylinder pushes the mechanical arm to open the gripper. Once aligned with a fixed point such as the ship's railing or deck edge, the hydraulic fluid pushes a piston, causing the gripper to embrace and clamp the target structure, securely connecting the manned platform to the ship through mechanical engagement.

[0019] In an optional embodiment, the protective device is a retractable guardrail or an anti-slip net, and its retractable stroke is synchronized with the retractable manned platform.

[0020] The protective device utilizes a retractable guardrail, whose extension and retraction travel is synchronized with the retractable manned platform, and coordinated with the platform through mechanical linkage or electronic control systems. Specifically, the retractable guardrail is arranged along both sides of the retractable manned platform and is composed of multiple nested guardrail units. When the retractable manned platform extends outward via multi-stage nested telescopic arms, the guardrail extends synchronously with the platform, with each guardrail unit sequentially deploying to form a complete protective structure. When the platform retracts, the guardrail retracts to its initial state.

[0021] Alternatively, the protective device uses an anti-skid net, whose telescopic stroke is synchronized with the retractable manned platform, and coordinated telescopic movement with the platform is achieved through mechanical linkage or an electronic control system. Specifically, the anti-skid net is laid along the surface or side of the retractable manned platform and is made of a flexible anti-skid material (such as a weather-resistant rubber mesh or a metal woven mesh). The mesh surface has raised patterns or an anti-skid coating, which can increase the friction between the operator's soles and the platform surface. When the retractable manned platform is extended outward through multi-stage nested telescopic arms, the anti-skid net is unfolded synchronously with the platform, covering the platform surface or forming a side protection net; when the platform retracts, the anti-skid net is synchronously retracted or folded to its initial state.

[0022] In an optional embodiment, the floating platform compensation boarding device further includes a power generation box, which is electrically connected to the wave and position compensation device and the retractable manned boarding device through cables.

[0023] The floating platform compensation boarding device includes a generator box, which is electrically connected to the wave and position compensation device and the retractable manned boarding device through cables to provide power support for the entire system. Specifically, the generator box can be equipped with a diesel generator, a battery pack or a solar power supply module, etc., which can be flexibly selected according to the energy configuration requirements of the floating platform. When the device is started, the generator box outputs electrical energy, which is transmitted via cables to the wave and position compensation device (such as a hydraulic cylinder, a multi-degree-of-freedom motion platform), driving it to offset the platform displacement caused by the waves, and at the same time provide power to the multi-stage nested telescopic arms of the retractable manned boarding device, the manned platform fixing unit (such as a vacuum suction cup, a hydraulic mechanical clamp) and the protective device (such as a retractable guardrail, an anti-slip net) to ensure that all components operate in coordination.

[0024] In an optional embodiment, the floating platform compensation boarding device further includes a staircase, one end of which is fixed to the deck and the other end is connected to the entrance of the retractable manned boarding device.

[0025] The floating platform compensating boarding device is equipped with a staircase, one end of which is fixed to the deck of the floating platform and the other end is connected to the entrance of the retractable manned boarding device, forming a passage connecting the deck and the manned platform.

[0026] In an optional embodiment, the fixing and angle adjustment device includes:

[0027] Rotate the base to adjust the angle in the horizontal plane;

[0028] Locking mechanism for fixing the rotation angle.

[0029] In an optional embodiment, a manned platform is provided on the top of the wave and position compensation device for carrying operating personnel.

[0030] In an optional embodiment, the floating platform includes a float assembly and a support assembly, the float assembly includes a buoy and a cross brace, and the support assembly includes a column and a deck. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0047] Floating offshore platforms are mostly floating offshore oil platforms or floating offshore wind power platforms. There are currently few of them and most of them operate independently.

[0048] Most of the current wave position compensation boarding devices are located on ships, but the adaptability of ships to floating platforms varies. In addition, due to the limitations of ship type and boarding method, the wave position compensation boarding devices located on ships are not friendly to floating offshore platforms, resulting in many operation and maintenance ships being unable to or having difficulty boarding floating offshore platforms.

[0049] To this end, this embodiment provides a floating platform compensating boarding device to solve the problem that existing operation and maintenance vessels have difficulty boarding floating offshore platforms.

[0050] The following combination Figures 1 to 4 , describing embodiments of the present invention.

[0051] According to an embodiment of the present invention, on the one hand, a floating platform compensation boarding device is provided, including a wave and position compensation device 1 and a retractable manned boarding device 5, the wave and position compensation device 1 is used to be fixedly installed on the deck 31 of the floating platform; the retractable manned boarding device 5 is connected to the wave and position compensation device 1 through a fixing and angle adjustment device 8; the retractable manned boarding device 5 includes a retractable manned platform 53, a manned platform fixing unit 52 and a protective device 54, the retractable manned platform 53 is used to overlap the operating ship, the manned platform fixing unit is provided at the end of the retractable manned platform 53, and is used to adsorb or grasp the ship; the protective device 54 is arranged along the retractable manned platform 53.

[0052] When the floating platform compensation and docking device is in operation, the wave and position compensation device 1 is fixedly installed on the floating platform deck 31. After activation, it can offset the impact of waves to maintain the stability of the device. The retractable manned boarding device 5 is connected to the wave and position compensation device 1 through a fixing and angle adjustment device 8. It can adjust its angle according to the position of the operating vessel. Then, the retractable manned platform 53 is extended outward to overlap the vessel. The manned platform fixing unit 52 at its end firmly fixes the manned platform 9 to the vessel through adsorption or gripping. At the same time, the protective device 54 arranged along the platform is synchronously deployed to form a safety protection structure to prevent workers from falling. This working mode allows the device to adapt to the docking requirements of different ships. Through the stabilizing effect of the wave and position compensation device 1, the flexible overlap of the retractable manned boarding device 5, the reliable connection of the manned platform fixing unit 52, and the safety protection of the protective device 54, it effectively solves the problem of incompatibility between existing operation and maintenance ships and floating platforms, ensuring that workers can move smoothly and safely between the floating platform and the ship, and improving the convenience and safety of marine operations.

[0053] In one embodiment, Figure 3 As shown, the wave and position compensation device 1 includes a hydraulic cylinder or a multi-degree-of-freedom motion platform for offsetting the platform displacement caused by waves.

[0054] In this embodiment, if Figure 3As shown, the wave and position compensation device 1 includes a hydraulic cylinder or a multi-degree-of-freedom motion platform. When waves act on the floating platform, the hydraulic cylinder can sense and offset the platform displacement caused by the waves in real time through the telescopic action of the hydraulic system or the multi-degree-of-freedom motion platform with its multi-directional movement ability, and continuously adjust the position and posture of the retractable manned boarding device 5 to keep it stable, ensuring that the retractable manned platform 53 is not affected by wave fluctuations when docking with the operating vessel, providing a smooth boarding path for the operating personnel, effectively solving the problem of unstable boarding caused by waves, and ensuring the safety and reliability of the boarding process.

[0055] In one embodiment, the telescopic manned platform 53 includes multi-stage nested telescopic arms.

[0056] In this embodiment, the retractable manned platform 53 utilizes a multi-stage, nested telescopic arm structure. The platform's length is adjusted through the orderly extension and retraction of each telescopic arm section. When docking with a vessel, the multi-stage, nested telescopic arms extend outward at an appropriate speed based on the distance between the vessel and the floating platform, precisely reaching the vessel's berthing position. Once the docking operation is complete, the arms retract sequentially to their initial position. This structural design provides the retractable manned platform 53 with flexible expansion and contraction capabilities, adapting to docking requirements at varying distances. Furthermore, the nested design ensures the platform's structural strength and stability when extended, providing a reliable docking channel for workers traveling between the floating platform and the vessel.

[0057] Specifically, a multi-stage telescopic boom is typically composed of multiple nested boom sections of varying diameters. Each section can slide inside or outside of adjacent sections, with the extension and retraction sequence of each section controlled by hydraulic or electric drive. To extend, the drive system pushes each section outward in a preset sequence until it reaches the required length to connect with the vessel. To retract, the drive system retracts each section in the reverse order, returning the entire boom to its initial compact state.

[0058] In one embodiment, the manned platform fixing unit is a vacuum suction cup.

[0059] In this embodiment, the manned platform fixing unit uses a vacuum suction cup. Its working principle is to extract the air inside the suction cup to create negative pressure, so that it is tightly attached to the flat surface of the operating vessel, such as the deck and bulkhead. Specifically, the vacuum suction cup is usually made of rubber or elastic material. After contact with the surface of the vessel, a vacuum generating device (such as a vacuum pump) is activated, rapidly exhausting the air inside the suction cup, creating an air pressure difference between the inside and outside of the suction cup, thereby generating an adsorption force to fix the manned platform 9 to the vessel.

[0060] In one embodiment, the manned platform fixing unit is a hydraulic mechanical clamp.

[0061] In this embodiment, the manned platform's securing unit utilizes a hydraulic mechanical clamp, whose core principle is to achieve a rigid clamping of the ship's structure using the driving force of the hydraulic system. Specifically, the hydraulic mechanical clamp typically consists of a hydraulic cylinder, a mechanical arm, and a clamping jaw. When the work vessel approaches, the hydraulic system activates, and the cylinder pushes the mechanical arm to open the clamping jaw. After aligning the clamping jaw with a fixed point such as the ship's railing or deck edge, the hydraulic fluid pushes a piston, causing the clamping jaw to embrace and clamp the target structure, securely connecting the manned platform 9 to the ship through mechanical engagement.

[0062] In one embodiment, the protection device 54 is a retractable guardrail, and its retractable stroke is synchronized with the retractable manned platform 53 .

[0063] In this embodiment, the protective device 54 utilizes a retractable guardrail, whose extension and retraction travel is synchronized with the retractable passenger platform 53, and coordinated with the platform through mechanical linkage or an electronic control system. Specifically, the retractable guardrail is arranged along both sides of the retractable passenger platform 53 and is composed of multiple nested guardrail units. When the retractable passenger platform 53 extends outward via a multi-stage nested telescopic arm, the guardrail extends synchronously with the platform, with each guardrail unit sequentially deploying to form a complete protective structure. When the platform retracts, the guardrail retracts to its initial state.

[0064] In one embodiment, the protection device 54 is an anti-slip net, and its telescopic stroke is synchronized with the telescopic manned platform 53.

[0065] In this embodiment, the protective device 54 is a non-slip net whose telescopic travel is synchronized with the retractable manned platform 53, and is coordinated with the platform through mechanical linkage or an electronic control system. Specifically, the non-slip net is arranged along the surface or side of the retractable manned platform 53 and is made of a flexible non-slip material (such as a weather-resistant rubber mesh or a woven metal mesh). The net surface has raised patterns or a non-slip coating, which can increase the friction between the operator's shoe soles and the platform surface. When the retractable manned platform 53 is extended outward via the multi-stage nested telescopic arms, the non-slip net is deployed synchronously with the platform, covering the platform surface or forming a side protection net; when the platform retracts, the non-slip net is synchronously retracted or folded to its initial state.

[0066] In one embodiment, the floating platform compensation boarding device further includes a power generation box 6 , which is electrically connected to the wave and position compensation device 1 and the retractable manned boarding device 5 via cables.

[0067] In this embodiment, the floating platform compensation boarding device includes a generator box 6, which is electrically connected to the wave and position compensation device and the retractable manned boarding device 5 through a cable to provide power support for the entire system. Specifically, the generator box 6 can be equipped with a diesel generator, a battery pack or a solar power supply module, etc., which can be flexibly selected according to the energy configuration requirements of the floating platform. When the device is started, the generator box 6 outputs electrical energy, which is transmitted via a cable to the wave and position compensation device 1 (such as a hydraulic cylinder, a multi-degree-of-freedom motion platform), driving it to offset the platform displacement caused by the waves, and at the same time provide power to the multi-stage nested telescopic arms of the retractable manned boarding device 5, the manned platform fixing unit (such as a vacuum suction cup, a hydraulic mechanical clamp) and the protective device 54 (such as a retractable guardrail, an anti-slip net) to ensure that all components operate in coordination.

[0068] In one embodiment, the floating platform compensation boarding device further includes a staircase 7 , one end of which is fixed to the deck 31 , and the other end of which is connected to the entrance of the retractable manned boarding device 5 .

[0069] In this embodiment, the floating platform compensation boarding device is equipped with a staircase 7, one end of which is fixed to the deck 31 of the floating platform, and the other end is connected to the entrance of the retractable manned boarding device 5, forming a passage through the deck 31 and the manned platform 9.

[0070] In one embodiment, the fixing and angle adjustment device 8 includes a rotating base and a locking mechanism. The rotating base realizes angle adjustment in the horizontal plane; the locking mechanism is used to fix the rotation angle.

[0071] In this embodiment, the fixing and angle adjustment device 8 is composed of a rotating base and a locking mechanism, which enables the horizontal adjustment and fixing of the retractable manned boarding device 5. The rotating base is typically mounted on top of the wave and position compensation device 1, supporting the retractable manned boarding device 5 via a bearing or gear transmission structure, allowing it to rotate about a vertical axis, thereby flexibly adjusting its direction in the horizontal plane according to the position of the operating vessel. The locking mechanism is composed of components such as hydraulic calipers and mechanical bolts. Once the rotating base adjusts the retractable manned boarding device 5 to an appropriate angle, the locking mechanism is activated, fixing the position of the rotating base through mechanical engagement or hydraulic clamping to prevent angular deviation caused by wave impact.

[0072] In one embodiment, a manned platform 9 is provided on the top of the wave and position compensation device 1 for carrying operating personnel.

[0073] In this embodiment, a manned platform 9 is mounted on top of the wave and position compensation device 1. This platform is directly attached to the device's superstructure and dynamically adjusts to maintain platform stability, providing a support structure for personnel. When waves impact the floating platform, the wave and position compensation device 1 (e.g., a hydraulic cylinder or multi-degree-of-freedom motion platform) counteracts the platform's displacement and sway in real time, ensuring that the manned platform 9 remains horizontal and stable, preventing personnel from becoming unstable due to wave impacts.

[0074] In one embodiment, the floating platform includes a float assembly 2 and a support assembly 3 . The float assembly 2 includes a buoy 21 and a cross brace 22 . The support assembly 3 includes a column 32 and a deck 31 .

[0075] In this embodiment, the floating platform is composed of a buoyancy assembly 2 and a support assembly 3, which work together to ensure the floating stability and structural strength of the platform at sea. The buoyancy assembly 2 includes a buoy 21 and a cross brace 22. The buoy 21 is usually a hollow and closed cylindrical structure made of high-strength and corrosion-resistant materials (such as steel or composite materials). It supports the entire platform floating on the sea surface through its own buoyancy. Its number and size are designed according to the platform load requirements. For example, multiple buoys 21 are symmetrically arranged to balance the buoyancy; the cross brace 22 is a transverse member connecting the buoys 21. It is fixed between the buoys 21 by welding or bolts to form a rigid frame structure, which enhances the overall rigidity of the buoyancy assembly 2, prevents the buoys 21 from relative displacement under the action of waves, and ensures the stability of the platform when floating. The support assembly 3 includes a column 32 and a deck 31. The column 32 is installed vertically above the floating assembly 2 and serves as the supporting frame of the platform. It is usually made of steel pipes or steel sections. Its lower end is fixedly connected to the buoy 21, and the upper end supports the deck 31 to transfer the load of the deck 31 to the floating assembly 2. At the same time, the height of the column 32 can be adjusted according to the draft depth to ensure that the deck 31 is at an appropriate height above the water surface; the deck 31 is the working plane of the platform, laid on the top of the column 32, and is made of anti-slip steel plates or composite materials. The surface is provided with drainage grooves and can carry workers, equipment and boarding devices (such as wave and position compensation device 1 installed on the deck 31). The area and carrying capacity of the deck 31 are designed according to the function of the platform. For example, the deck 31 of the offshore wind power platform needs to reserve space for equipment installation.

[0076] The working mode of the floating platform compensation boarding device is as follows:

[0077] After the generator box 6 is started, it supplies power to the wave and position compensation device 1 and the retractable manned boarding device 5. The wave and position compensation device 1 offsets the platform displacement caused by the waves in real time to maintain the stability of the system; the retractable manned boarding device 5 is aligned with the operating vessel through the fixing and angle adjustment device 8, and its multi-stage nested telescopic arm drives the retractable manned platform 53 to extend, and the vacuum suction cup or hydraulic mechanical clamp at the end absorbs or grasps the vessel. At the same time, the retractable guardrail or anti-skid net arranged along the platform is synchronously deployed to form a safety protection; the operating personnel travel back and forth between the platform and the vessel through the stairs 7 connected to the deck 31; after the operation is completed, the fixing unit is disconnected, the telescopic arm retracts to its initial state, and the generator box 6 is powered off and stops working.
