BACKGROUND

Offshore platforms can be fixed or movably floated on the sea, and perform production operations or other offshore activities on the sea. In the life cycle of various offshore platforms, they need various operation and maintenance vessels to provide operation support, such as loading and unloading of cargoes, supplying and assisting in the maintenance of the platforms, etc. During these operations, the problem of the boarding of workers from the operation and maintenance vessel to the platform or from the platform to the operation and maintenance vessel is involved.

Existing boarding methods are usually to make the operation and maintenance vessel abut against the offshore platform and a worker boards the platform through a ladder of the offshore platform. However, when the operation and maintenance vessel approaches the platform, the vessel may collide with the platform due to the inertia of the vessel itself, resulting in damage to the platform and the operation and maintenance vessel itself. In addition, in the case of big wind and wave at sea, the operation and maintenance vessel can't be stably berthed at the offshore platform and the worker can't board the platform. It is necessary to wait for an appropriate wind and wave environment for the operation and maintenance vessel to stably berth at the offshore platform, resulting in a low boarding efficiency.

DESCRIPTION OF EMBODIMENTS

Exemplary embodiments are described in detail herein, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, same numbers in different drawings indicate the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Rather, they are merely examples of apparatuses consistent with certain aspects of the present application as detailed in the appended claims.

Other embodiments of the present application will be apparent to the skilled in the art from consideration of the specification and practice of the application disclosed herein. The present application is intended to cover any variations, uses, or adaptations of the application, which follow the general principle of the present application and include common general knowledge or common technical means in this technical field that are not disclosed in the present application. The specification and embodiments are to be regarded as exemplary only, with the true scope and spirit of the present application indicated by the claims.

In order to explain the technical solutions of the present application, specific embodiments will be provided in the following.

Offshore platforms can be fixed or movably floated on the sea, and perform production operations, or other offshore activities on the sea. For example, offshore platforms can include offshore wind power platforms, offshore oil drilling platforms, living platforms, offshore operations platforms, etc. In the life cycle of these offshore platforms, they need various operation and maintenance vessels to provide operation support, such as loading and unloading of cargoes, supplying, emergency evacuation and rescue, and assisting in the maintenance of the platforms, etc. During these operations, the problem of the boarding of a worker from the operation and maintenance vessel to the platform or from the platform to the operation and maintenance vessel is involved.

In a case that the offshore platform is an offshore wind power platform for an example, in the existing solution, the boarding of the worker on the operation and maintenance vessel from the vessel to the wind power platform can be realized by making the operation and maintenance vessel abut against the wind power platform, and then allowing the worker to board the platform through a ladder at the bottom of the wind power platform. However, when the operation and maintenance vessel approaches the platform, the vessel may collide with the platform due to the inertia of the vessel itself, resulting in damage to the platform and the operation and maintenance vessel itself. In addition, in the case of big wind and wave at sea, the operation and maintenance vessel can't be stably berthed at the offshore platform and the worker can't board the platform. It is necessary to wait for an appropriate wind and wave environment for the operation and maintenance vessel to stably berth at the offshore platform, resulting in a low boarding efficiency.

Alternatively, in the existing solution, it is also possible for the worker on the operation and maintenance vessel to board the wind power platform from the vessel by using a large-scale operation and maintenance vessel equipped with a connecting bridge apparatus. For example, FIG. 1 shows a structural schematic diagram of the boarding of a large-scale operation and maintenance vessel in the related art. As shown in FIG. 1, an operation and maintenance vessel 11 is equipped with a connecting bridge apparatus 12 having a dynamic positioning function. The connecting bridge apparatus 12 adjusts the position of a compensating ladder 121 provided on the connecting bridge apparatus 12 by means of the dynamic positioning function, and worker on the operation and maintenance vessel 11 can board a wind power platform 13 through the compensating ladder 121. However, the large-scale operation and maintenance mother vessel is expensive, and the cost of purchasing and renting the operation and maintenance mother vessel is higher for only routine maintenance.

In order to solve the above problems, embodiments of the present application provide a boarding apparatus for an offshore platform, through which boarding efficiency can be improved and the damage caused by the collision between a sea transporting apparatus and the offshore platform during the sea transport device is berthed at the offshore platform can be avoided.

FIG. 2 shows a structural schematic diagram of a boarding apparatus for an offshore platform according to an embodiment of the present application. As shown in FIG. 2, a boarding apparatus 20 can include a lifting apparatus 21 and a track structure 22. The track structure 22 is connected to a platform main body 23 of an offshore platform and extends beyond the platform main body 23; the lifting apparatus 21 is connected to the track structure 22, and the lifting apparatus 21 is at least capable of moving along the track structure 22 with a moored sea transporting apparatus 24;

- where the lifting apparatus 21 may include a ride-on assembly 211 for lifting transportation of a ride-on object between the track structure 22 and the sea transporting apparatus 24.

It should be noted that the ride-on object can go up and down between the sea transporting apparatus 24 and the offshore platform through the ride-on assembly 211, and the ride-on object can be a person or a good, or the ride-on object can also include both a person and a good. The sea transporting apparatus 24 can be any type of vessel, for example, a passenger vessel, a cargo vessel, an operation and maintenance vessel, etc.

It can be understood that the track structure 22 extends beyond the platform main body 23, and the lifting apparatus 21 moves on the track structure 22, so that the lifting apparatus 21 may be out of the range of the platform main body 23. In this way, when the ride-on object on the sea transporting apparatus 24 need to board the platform main body 23 through the lifting apparatus 21, the sea transporting apparatus 24 can move the lifting apparatus 21 above the sea transporting apparatus 24 without contacting the platform main body 23. Therefore, the non-contact boarding between the sea transporting apparatus 24 and the offshore platform is achieved. This overcomes the impossibility of boarding caused by marine environmental factors and improves boarding efficiency, and also avoids damage caused by the collision between the sea transporting apparatus 24 and the offshore platform when the sea transporting apparatus 24 is berthed at the platform.

Exemplary, a case that the offshore platform is an offshore wind power platform, the sea transporting apparatus is a small-scale operation and maintenance ship for the offshore wind power platform, and the ride-on object is a worker on the small-scale operation and maintenance ship is taken as an example. When the worker on the small-scale operation and maintenance ship needs to board the wind power platform, the small-scale operation and maintenance ship may be moored to the sea surface, and the worker can control the lifting apparatus 21 to move on the track structure 22 so as to make the lifting apparatus 21 moved above the small-scale operation and maintenance ship. After the lifting apparatus 21 is moved above the small-scale operation and maintenance ship, the worker can continue to control the ride-on assembly 211 on the lifting apparatus 21 to make the ride-on assembly 211 lowered onto the small-scale operation and maintenance ship. Then, the worker can be lifted from the small-scale operation and maintenance ship to the track structure 22 by taking the ride-on assembly 211, and then board the wind power platform from the track structure 22.

In some possible implementations, the lifting apparatus 21 may further include a remote control apparatus; the remote control apparatus is configured to receive a remote control signal and control the lifting apparatus 21 to move along the track structure 22.

It can be understood that the lifting apparatus 21 is connected to the track structure 22, and when the sea transporting apparatus 24 is moored to the sea surface and is not in contact with the platform main body 23, if the ride-on object needs to board the sea transporting apparatus 24 from the platform main body 23, the lifting apparatus 21 can be directly moved on the track structure 22 at this time. However, if the ride-on object needs to board the platform main body 23 from the sea transporting apparatus 24, the moving position of the lifting apparatus 21 cannot be controlled on the sea transporting apparatus 24. Therefore, by providing the remote control apparatus on the lifting apparatus 21, the lifting apparatus 21 can be remotely controlled to be moved above the sea transporting apparatus 24 at any time as long as the sea transporting apparatus 24 is moored at an appropriate position near the platform main body 23, so as to maximize the convenience of boarding.

Where, the remote control apparatus can be any type of apparatuses that can realize remote control. For example, an infrared remote control device, a bluetooth remote control device, etc. The type of the remote control apparatus can be selected based on actual use requirements, and the embodiments of the present application do not specifically limit this.

In some embodiments, the track structure 22 can be disposed on a structure of the offshore platform itself extending beyond the platform main body 23.

It can be understood that the track structure 22 needs to extend beyond the platform main body 23. If the offshore platform itself has structures extending beyond the platform main body 23, the structures may be directly used to build the track structure 22, and there is no need to build an additional carrier for the track structure 22, thus increasing the convenience of setting the boarding apparatus 20.

Exemplary, FIG. 3 is a structural schematic diagram of an offshore platform according to an embodiment of the present application. As shown in FIG. 3, in an offshore platform 30, a platform main body 23 is provided at the center of the top of a floating body assembly 31, the floating body assembly 31 includes four floating body structures 311, and the floating body assembly 31 is used for providing buoyancy for the platform main body 23. An outer wall of the platform main body 23 is provided with a stairway 231, and expanded stairways 32 are provided between the stairway 231 and the four floating body structures 311, respectively. When the offshore platform 30 is moored on the sea surface, the expanded stairways 32 are located above the sea level. At this time, the track structure 22 can be directly provided on any one of the expanded stairways 32, or each of the expanded stairways 32 is provided with a track structure 22, and track structures 22 disposed on respective expanded stairways 32 communicate with each other.

FIG. 4 is another structural schematic diagram of a boarding apparatus according to an embodiment of the present application. As shown in FIG. 4, the track structure 22 is provided on the expanded stairway 32, the expanded stairway 32 is provided between the stairway 231 on the platform main body 23 and the floating body structure body 311, and a part of the floating body structure 311 is located above a sea level line 41. When a worker on the sea transporting apparatus 24 needs to board the offshore platform, the sea transporting apparatus 24 can be moored below the track structure 22 between the platform main body 23 and the floating body structure 311, and then the lifting apparatus 21 is controlled to move to the top of the sea transporting apparatus 24, so as to achieve boarding through the lifting apparatus 21.

It should be noted that when the track structures 22 is disposed on the structure of the offshore platform itself extending beyond the platform main body 23, there should be enough space between the track structure 22 and the sea level to accommodate the offshore transporting apparatuses for mooring. That is, a distance of the track structure 22 from the sea level needs to be at least larger than a height of the sea transporting apparatus 24 when being moored on the sea surface. However, when the offshore platform is the structure as shown in FIG. 3, it is necessary to ensure that a distance between the platform main body 23 and the floating body structure 311 is larger than a size of the sea transporting apparatus 24. That is, when the sea transporting apparatus 24 is moored below the track structure 22, at least a space for accommodating the sea transporting apparatus 24 below the track structure 22 is needed.

In some embodiments, the configuration that the track structure 22 extends beyond the platform main body 23 can be achieved by additionally building a corridor on the platform main body 23 as a carrier of the track structure 22.

FIG. 5 is a structural schematic diagram of another boarding apparatus according to an embodiment of the present application. As shown in FIG. 5, the platform main body 23 is provided with a corridor 51 extending beyond the platform main body 23, and the track structure 22 is provided on the corridor 51.

It can be understood that when boarding, the sea transporting apparatus 24 needs to be moored below the track structure 22, so that the lifting apparatus 21 can be moved to the top of the sea transporting apparatus 24, and the boarding can be achieved by the lifting apparatus 21. Therefore, the longer the length of the track structure 22, the larger the sea space below the track structure 22, and thus the greater the operability of the sea transporting apparatus 24. If the corridor 51 is additionally built on the platform main body 23 as the carrier of the track structure 22, the longer the corridor 51 is, the longer the length of the buildable track structure 22. However, the longer the length of the corridor 51, the higher the structural strength of the corridor 51 needs to have. Therefore, in the embodiments of the present application, the length of the corridor 51 can be specifically determined based on actual use situations of the corridor 51 and actual use requirements of the track structure 22.

In some possible implementations, the lifting apparatus 21 can further include a power assembly; the ride-on assembly 211 is connected to the power assembly, the power assembly is used to drive the ride-on assembly 211 to lift the ride-on assembly 211 between the track structure 22 and the sea transporting apparatus 24.

Where, the power assembly can be an apparatus that provides kinetic energy for the ride-on assembly 211 to drive the ride-on assembly 211 to automatically lift the ride-on object between the track structure 22 and the sea transporting apparatus 24. The power assembly can be integrated with the lifting apparatus 21, or the power assembly can be connected to the lifting apparatus 21 as a separate apparatus.

In some possible implementations, the remote control apparatus is used to receive the remote control signal and control at least one of the following:

- the power assembly to drive the lifting apparatus 21 to move along the track structure 22;
- the power assembly to drive the ride-on assembly to lift between the track structure 22 and the sea transporting apparatus 24.

It can be understood that is that the power assembly is controlled by the remote control apparatus to drive the lifting apparatus 21 to move along the track structure 22. In this way, the lifting apparatus 21 can be remotely controlled to move above the sea transporting apparatus 24 at any time, thereby maximizing the convenience of boarding.

It can be understood that the power assembly is controlled by the remote control apparatus to drive the ride-on assembly 211 to automatically lift the ride-on object between the track structure 22 and the sea transporting apparatus 24.

In some possible implementations, the power assembly can be integrated with the lifting apparatus 21, or the power assembly can be connected to the lifting apparatus 21 as a separate apparatus.

In some possible implementations, the power assembly can drive the lifting apparatus 21 and/or the ride-on assembly 211 through power transmission methods such as gears, belts, pulley blocks, etc., this is not limited here. It should be noted that the power assembly can be any type of apparatus that can provide kinetic energy. For example, the power assembly can be an electric motor that consumes electrical energy to provide kinetic energy, or the power assembly also can be an internal combustion engine that consumes fossil fuels to provide kinetic energy, etc.

In some embodiments, the ride-on assembly 211 automatically lifts between the track structure 22 and the sea transporting apparatus 24, which can be achieved by remotely controlling the power assembly to drive the ride-on assembly 211 to lift.

Where, the remote control of the power assembly can be achieved through the foregoing remote control apparatus. For example, different control signals can be used to control the lifting apparatus 21 to move on the track structure 22, and to control the power assembly to drive the ride-on assembly 211 to lift. The remote control apparatus selects to control the lifting apparatus 21 to move on the track structure 22 or to control the power assembly to drive the ride-on assembly 211 to lift based on the received different control signals. Alternatively the remote control of the power assembly can also be achieved by integrating an additional remote control apparatus in the power assembly. Different remote control apparatuses may receive different control signals, and different remote control apparatuses may be used to achieve the control of the lifting apparatus 21 to move on the track structure 22 or to achieve the control of the power assembly to drive the ride-on assembly 211 to lift, respectively.

In some embodiments, the ride-on assembly 211 can not only be automatically lifted through the power assembly, but also be manually lifted by human labor.

It can be understood that when the power assembly is unable to provide kinetic energy, for example, when the power assembly is run out of energy or is faulted, or when the lifting apparatus 21 is not equipped with the power assembly, the ride-on assembly 211 cannot achieve automatic lifting. At this time, it is also possible to manually lift the ride-on assembly 211 by human labor.

Exemplary, FIG. 6 is a structural schematic diagram of a lifting apparatus according to an embodiment of the present application, as shown in FIG. 6. the lifting apparatus 21 includes a pulley assembly 6 that is movable on the track structure 22, and the ride-on assembly 211 is a sling connected to the pulley assembly 61. When the sea transporting apparatus 24 is moored below the track structure 22, the lifting apparatus 21 can move above the sea transporting apparatus 24. At this point, both ends of the sling can come into contact with the sea transporting apparatus. A case in which the riding object is a worker on the sea transporting apparatus is taken as an example. When the worker needs to be transported to the offshore platform, the worker can be fixed to one end of the sling, and other workers on the sea transporting apparatus 24 can pull the other end of the sling, so as to drive the worker who needs to board the platform to rise to the track structure 22, and then the worker will move from track structure 22 to the offshore platform.

In some possible implementations, the ride-on assembly 211 may at least include a sling and/or an elevator.

In some embodiments, when the ride-on assembly 211 is manually lifted by human labor, the ride-on assembly 211 can be a sling. For example, the lifting apparatus 21 may include a pulley assembly as shown in FIG. 6, which is movable on the track structure 22. At this point, the sling can be connected to the pulley assembly and the ride-on object can be fixed to one end of the sling, and the other end of the sling can be manually pulled to lift the ride-on object to the track structure 22.

In other embodiments, when the automatic lifting of the ride-on assembly 211 is achieved through the power assembly, the ride-on assembly 211 can include a sling, or can include an elevator, or the ride-on assembly 211 can also include both the sling and the elevator. For example, FIG. 7a-7c are structural schematic diagrams of the ride-on assemblies 211 according to embodiments of the present application. Where, FIG. 7a is a structural schematic diagram of a ride-on assembly including a sling according to an embodiment of the present application. Where, the sling 71 is connected to a winder 72. At this time, the power assembly controls the winder to roll up or release the sling, thus the lifting of the sling between the track structure 22 and the sea transporting apparatus 24 is achieved. FIG. 7b is a structural schematic diagram of a ride-on assembly including an elevator according to an embodiment of the present application. Where, the elevator 73 is composed of multiple telescopic structures 731. When the multiple telescopic structures 731 are unfolded, the elevator 73 can contact the sea transporting apparatus 24. FIG. 7c is a structural schematic diagram of a ride-on assembly including a sling and an elevator at the same time according to an embodiment of the present application. Where, one end of the elevator 73 can be rotatably connected to the platform main body 23, and the other end of elevator 73 is connected to two slings 71, the two slings 71 are respectively connected to the platform main body 23 through two winders 72. The two winders 72 roll up or release the slings 71 synchronously. When the sling 71 is rolled up, the elevator 73 rises; when the sling 71 is released, the elevator descends until it comes into contact with the sea transporting apparatus 24.

In some embodiments, when the ride-on assembly 211 achieves automatic lifting by kinetic energy provided through the power assembly, the power assembly can also provide kinetic energy for the movement of the lifting apparatus 21 on the track structure 22. Based on this, in some possible implementations, the power assembly is also used to drive the lifting apparatus 21 to move on the track structure 22 when the remote control apparatus receives the control signal.

Exemplary, the remote control apparatus can control the power assembly to provide kinetic energy for the movement of the lifting apparatus 21 on the track structure 22 or for the lifting of the ride-on assembly 211. For example, different control signals can be used to control the lifting apparatus 21 to move on the track structure 22, and to control the power assembly to drive the ride-on assembly 211 to lift, can be different control signals. The remote control apparatus selects to control the power assembly to drive the lifting apparatus 21 to move on the track structure 22 or to drive the ride-on assembly 211 to lift based on the received different control signals.

In some possible implementations, the power assembly includes an energy storage component; the energy storage component is used to provide kinetic energy for the power assembly.

It should be noted that the type of the energy storage component can be determined based on the type of the power assembly. For example, the power assembly can be an electric motor that consumes electrical energy, and the energy storage component can be an energy storage battery that stores electrical energy. Where, in order to ensure that energy storage battery can provide long-term power supply, a pure battery material with high energy density can be used for the energy storage battery, such as a lithium iron phosphate battery, a flow battery, etc. with large capacity and long-term energy storage. Alternatively, the power assembly can also be an internal combustion engine that consumes oil, and the energy storage component here can be a fuel tank for storing oil.

In some embodiments, the power assembly can be completely powered by the energy storage component, or the power assembly can also be powered by an independent energy supply system, with an assisted energy supply by the energy storage component. When the power assembly is completely powered by the energy storage component, the power assembly can only function normally when the energy in the energy storage component meets the requirements of the power assembly. When the power assembly has an independent energy supply system, and a case that the energy supply system of the power assembly is a power system and the energy storage component is an energy storage battery is taken as an example, the power assembly can be directly connected to a power grid and is powered through the power grid; when there is power outage or failure in the grid, the power assembly can continue to be powered by the energy storage component. The energy storage component can also be connected to the power grid, and when the energy storage component is not in operation, the energy storage component can be charged through the power grid to ensure the continuous power supply of the power assembly when the power grid cannot provide power to the power assembly.

In some possible implementations, the power assembly is connected to the platform main body; the platform main body 23 is used to provide kinetic energy for the power assembly.

It can be understood that when the offshore platform itself is a platform capable of generating energy, the power assembly can directly use the energy generated by the platform itself without the need to connect to an additional energy supply system.

Exemplary, the offshore platform is an offshore wind power generation platform, and the power assembly is an electric motor that consumes electricity. At this point, an input end of the power assembly can be directly connected to an output end of the wind power platform, and the power assembly is powered by the electrical energy output from the wind power platform.

In embodiments of the present application, the platform main body 23 directly provides kinetic energy to the power assembly, achieving on-site consumption of energy generated by the platform main body, without the need to design an additional energy supply system for the power assembly, thereby improving the convenience of the overall setting of the boarding apparatus.

In some possible implementations, the track structure 22 is connected to the platform main body 23 through a rotation control assembly; the rotation control assembly is used to receive the remote control signal and control the track structure 22 to rotate along the outer wall of the platform main body 23.

Exemplary, FIG. 8 is a structural schematic diagram of the track structure 22 according to an embodiment of the present application. As shown in FIG. 8, the track structure 22 is connected to the outer wall of the platform main body 23 through a rotation control assembly 81 that is rotatable around the outer wall of the platform main body 23.

It can be understood that the sea transporting apparatus 24 needs to be moored below the track structure 22, so that by means of the lifting of the ride-on assembly connected to the lifting apparatus 21 on the track structure 22, the boarding of the ride-on object from the sea transporting apparatus 24 onto the platform is achieved. By providing the track structure 22 to rotate along the outer wall of the platform main body 23, the sea transporting apparatus 24 can be moored at any sea area below a rotation area of the track structure 22, thereby improving the operability of the sea transporting apparatus 24, facilitating the selection of a suitable position for mooring of sea transporting apparatus 24, and thus improving boarding efficiency.

In some possible implementations, each of two ends of the track structure 22 is provided with a limit apparatus, respectively, the limit apparatus is used to limit a displacement position of the lifting apparatus 21.

It can be understood that the lifting apparatus 21 is moved on the track structure 22. In order to prevent the lifting apparatus 21 from sliding out of the track structure 22 during movement, limit apparatuses can be added at both ends of the track structure 22 to limit the position where the lifting apparatus 21 can be moved on the track structure 22.

FIG. 9 is a structural schematic diagram of the track structure 22 in an embodiment of the present application. As shown in FIG. 9, two ends of the track structure 22 are provided with limit apparatuses 91 respectively, and the lifting apparatus 21 can move within the area limited by the two limit apparatuses 91.

In some possible implementations, the platform main body 23 is provided with a ladder; the ladder is located on the outer wall of the platform main body 23 and below the track structure 22.

Where, the lifting apparatus is used to lift the ride-on object between the ladder and the sea transporting apparatus 24.

It can be understood that the offshore platform is usually provided with a ladder to facilitate a worker on the sea transporting apparatus 24 to board the platform. However, due to the fact that the ladder is usually made of a metal material, the ladder is prone to corrosion when in contact with seawater. To avoid that the ladder cannot be used due to seawater corrosion, the ladder can be provided at the sea level line position. Meanwhile, due to the presence of waves on the sea surface, the actual height to which seawater can corrode is relatively high, and thus the position of the ladder may be higher in consideration of the influence of waves. Therefore, in embodiments of the present application, the achievement of boarding the platform by means of the lifting apparatus 21 may also be that the worker who needs to board the platform is lifted from the sea transporting apparatus 24 to the ladder by the lifting apparatus 21, and then the worker can board the platform through the ladder.

Exemplary, FIG. 10 is a structural schematic diagram of an offshore platform 30 according to an embodiment of the present application. As shown in FIG. 10, the platform main body 23 is provided with a ladder 101, and the ladder 101 is located below the track structure 22. The lifting apparatus 21 is movable on the track structure 22, and the ride-on assembly 211 on the lifting apparatus 21 can be lifted between the ladder and the sea transporting apparatus 24. The ride-on object on the sea transporting apparatus 24 can be transported to the ladder 101, or the ride-on object can be transported from the ladder 101 to the sea transporting apparatus 24.

In embodiments of the present application, the lifting apparatus 21 moves on the track structure 22 along with the moored sea transporting apparatus 24, and the ride-on object is lifted between the track structure 22 and the sea transporting apparatus 24 using the ride-on assembly 211. The lifting apparatus 21 can adjust its position on the track structure 22 according to the position of the sea transporting apparatus 24, and the sea transporting apparatus 24 does not need to be berthed at the offshore platform. In this way, non-contact boarding between the sea transporting apparatus 24 and the offshore platform is achieved through the lifting apparatus 21. This overcomes the impossibility of boarding caused by marine environmental factors and improves boarding efficiency, and also avoids damage caused by collisions between the sea transporting apparatus 24 and the offshore platform when the sea transporting apparatus is berthed at the offshore platform.
