Description

Technical Field

[0001] The present invention relates to the field of multi-functional jack-up platforms, and particularly to a new standard interface for docking the multi-functional superstructure of a jack-up platform with a base. Background Art

[0002] In the prior art, a multi-functional jack-up platform is composed of a multi-functional superstructure module and a platform base. By modularizing single functions, various modules and hulls can be combined to form diverse functions. The superstructure module can be a functional module such as a wind power installation module platform, a living module platform, a workover module platform, a gas compression module platform, an offshore mobile power station module platform, a nearshore construction module platform, etc. The platform base is a box-shaped welded hull, with interfaces for each functional module and necessary equipment reserved to facilitate the installation of the multi-functional superstructure module. In order to ensure the flexible configuration of the functional module and facilitate modification or equipment upgrade, it is necessary to design the applicability and standardization of the interface.

[0003] In order to better reflect the generality and standardization of the modular technology, during the module conversion process, problems such as precise difference, low efficiency, insufficient strength, and interface mismatch occur when different modules are docked with the platform base. How to design a conversion interface that can be applied to the base and functional module is an urgent technical problem that needs to be solved in platform design. Summary of the Invention

[0004] In view of the above technical problems, the present invention provides a new standard interface for docking the multi-functional superstructure of a jack-up platform with a base, which can be used for different water area working conditions. The standard interface for docking the multi-functional superstructure of a jack-up platform with a base has high precision, high efficiency, sufficient strength, and a matching interface during docking, and evaluates and analyzes the force conditions of the involved interfaces.

[0005] To achieve the above object, the technical solution adopted by the present invention is:

[0006] A standard interface for a multi-functional platform of a jack-up platform, which is composed of a module docking interface and a module main beam and a deck beam arranged on the module docking interface; wherein:

[0007] The module pair interface is used for the disassembly and assembly of functional modules. The module pair interface includes an upper module interface, a guiding structure, and a general base interface. The guiding structure is arranged in the interval between the upper module interface and the general base interface and serves as a transition buffer device between the upper module interface and the general base interface. The upper module interface and the general base interface are connected by bolts. The upper module interface is connected to the multi-functional superstructure module, and the general base interface is arranged on the basic platform. The guiding structure is formed by combining a side plate and a base to form a closed cavity structure. The length of the base is the same as the length of the transverse connecting plate of the general base. The general base interface is composed of a lateral reinforcing gusset plate, a general base guiding plate, and a general base transverse connecting plate. The general base interface is arranged on the longitudinal bulkhead.

[0008] The upper module interface consists of a connecting column, a through-connecting gusset plate, and an arc part of the transition structure. The upper part of the connecting column is connected to the structural column of the superstructure, and the lower part of the connecting column is connected to the cross beam of the module main body. The through-connecting gusset plate penetrates and wraps the connecting column. The arc part of the transition structure transversely cuts the side end of the top of the connecting column. The arc part of the transition structure and the bottom of the connecting column form an arc structure. At least three vertical guiding plates are provided in the middle and lower parts of the cross beam of the module main body. The vertical guiding plates correspond to the guiding structure and the general base guiding plate and are used to position and correct the upper module interface. A transverse connecting plate is arranged at the lower end of the upper module interface, and the transverse connecting plate is connected to the general base transverse connecting plate.

[0009] When the module pair interface runs downward for fixed assembly, the upper module structure is located in the side plate cavity of the guiding structure, and the upper module structure is connected to the side plate by connecting bolts.

[0010] When the module pair interface runs downward for fixed assembly, the guiding structure is connected to the lateral reinforcing gusset plate by connecting bolts. The vertical guiding plate passes through the guiding structure and cooperates with the general base guiding plate, and the transverse connecting plate is connected to the general base transverse connecting plate.

[0011] The guiding structure is composed of at least four side plates inclined at 60 - 80 degrees to form a closed rectangular space.

[0012] Reinforcing ribs are provided on the module pair interface. After the upper module interface, the guiding structure, and the general base interface are assembled and connected, they are fixedly arranged on the longitudinal bulkhead.

[0013] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art:

[0014] A multi-functional platform standard interface for a jack-up platform in this application adopts an upper-interface design and a base-interface design for multi-functional modules, facilitating the disassembly and assembly of functional modules. To meet the requirements of convenient installation and precision for the two interfaces, a guiding device design between the interfaces is added. The interface consists of an upper-module base interface, a guiding structure, and a general base interface. The upper-module interface and the general base interface are connected by bolts. The upper-module interface is connected to different multi-functional superstructure modules, and the base interface is set on the basic platform. The guiding structure provides a positioning function for the module base interface and the general base interface, ensuring rapid positioning during installation and the accuracy of the installation position. Combining the characteristics of the platform structure, the installation position and reinforcement design of the interface are carried out. Considering the strength requirements after installation, appropriate connection and installation methods are selected. The design is divided into two parts: one is to design the structure of the interface to ensure the convenience and accuracy of module installation; the other is to design the position of the interface to meet the requirements of local strength and hoisting; the third is to design the connection method between the standard interface and the main body to ensure that the strength of the main body is not reduced.

[0015] For a multi-functional jack-up platform, the single functions are modularized to enable various modules and the hull to be combined to form diverse functions. A new type of docking standard interface between the multi-functional superstructure and the base of the jack-up platform is adopted. The superstructure modules are functional modules such as a wind power installation module platform, a living module platform, a workover module platform, a gas compression module platform, an offshore mobile power station module platform, and an inshore construction module platform. The platform base is a box-shaped welded hull, with interfaces for each functional module and necessary equipment reserved, facilitating the installation of multi-functional superstructure modules. In addition, to ensure the flexible configuration of functional modules, facilitate refitting or equipment upgrading, the applicability and standardization of the interfaces are also very good. Secondly, the interfaces between the design modules and the main body are designed, and the interfaces are designed in a general and standardized manner, thus realizing the generalization of the platform and improving the utilization value of the platform itself. Through the assembly of standard interfaces, the construction efficiency of the platform can be improved, and each module can be manufactured separately, improving production efficiency and reducing production costs to a certain extent. The design of modular standard interfaces can also make the modules easy to maintain, improve the usability of the platform, and the entire module can be replaced when necessary, improving the economy and repeatability of the platform functions. It is possible to develop a docking standard interface between the multi-functional superstructure and the base of the jack-up platform for different water area working conditions, focusing on solving problems such as precise difference, low efficiency, insufficient strength, and interface non-conformity when different modules are docked with the platform base, evaluating the stress conditions of the involved interfaces and conducting strength analysis, which has practical significance for the development and operation of new platforms.

[0016] Based on the sea condition data applicable to various types of jack-up platforms investigated and the characteristics of the working conditions of each jack-up platform, the typical extreme sea condition parameters applicable to this jack-up platform are derived. The design load should consider various modules that may be installed on the base to ensure the structural safety of each function when all module functions are installed.

Among them: the module mating interface 1 is used for the disassembly and assembly of functional modules. The module mating interface 1 includes an upper module interface 100, a guiding structure 200 and a general base interface 300. The guiding structure 200 is arranged in the interval between the upper module interface 100 and the general base interface 300 and serves as a transition buffer device between the upper module interface 100 and the general base interface 300. The upper module interface 100 and the general base interface 300 are connected by bolts 400. The upper module interface 100 is connected to the multi-functional superstructure module, and the general base interface 300 is arranged on the basic platform. The guiding structure 200 is formed by combining a side plate 201 and a base 202 to form a closed cavity structure. The length of the base 202 is the same as the length of the general base transverse connecting plate 302. The general base interface 300 is composed of a lateral reinforcing gusset 301, a general base guide plate 302 and a general base transverse connecting plate 303. The general base interface 300 is arranged on the longitudinal bulkhead 3.

[0026] The upper module interface 100 is composed of a connecting column 101, a through-connecting gusset 102 and a transition structure arc part 103. The upper part of the connecting column 101 is connected to the superstructure construction column, and the lower part of the connecting column 101 is connected to the module main beam 2. The through-connecting gusset 102 penetrates and wraps the connecting column 101. The transition structure arc part 103 is transversely cut at the top side end of the connecting column 101. The transition structure arc part 103 and the bottom of the connecting column 101 form an arc structure. At least three vertical guide plates 104 are arranged in the middle and lower parts of the module main beam 2. The vertical guide plates 104 correspond to the guiding structure 200 and the general base guide plate 302 and are used for positioning and correcting the position of the upper module interface 100. A transverse connecting plate 105 is arranged at the lower end of the upper module interface 100, and the transverse connecting plate 105 is connected to the general base transverse connecting plate 303.

[0027] As Figure 4 shown, when the module mating interface 1 runs downward for fixed assembly, the upper module structure is located in the cavity of the side plate 201 of the guiding structure 200, and the upper module structure is connected to the side plate 200 by connecting bolts. When the module mating interface 1 runs downward for fixed assembly, the guiding structure 200 is connected to the lateral reinforcing gusset 301 by connecting bolts. The vertical guide plate 104 passes through the guiding structure 200 and cooperates with the general base guide plate 302, and the transverse connecting plate 105 is connected to the general base transverse connecting plate 303. The guiding structure 200 is composed of at least four side plates 201 inclined at 60-80 degrees to form a closed rectangular space.

[0028] As Figure 5As shown, there is a reinforcing rib 500 on the module interface 1. After the upper module interface 100, the guiding structure 200 and the general base interface 300 are assembled and connected, they are fixedly arranged on the longitudinal bulkhead 600.

[0029] The specific inventive concept of this application is: The design of the module standard interface is for the convenience of disassembly and assembly of functional modules. The interface design is as Figures 1-3 shown. The design is divided into two parts: one is to design the structure of the interface to ensure the convenience and accuracy of module installation; the second is to design the position of the interface to meet the requirements of local strength and hoisting; the third is to design the connection method between the standard interface and the main body to ensure that the strength of the main body is not reduced.

[0030] As Figure 1 shown, the standardized interface consists of an upper module base interface, a guiding structure and a general base interface. The upper module interface and the general base interface are connected by bolts. The upper module interface is connected to different multi-functional superstructure modules. The base interface is arranged on the basic platform. The guiding structure provides a positioning function for the module base interface and the general base interface to ensure quick positioning during installation and the accuracy of the installation position.

[0031] The upper module base interface consists of a connecting column, a penetrating connecting gusset plate, a transition column arc structure, a vertical guide plate and a transverse connecting plate. The upper part of the connecting column is connected to the superstructure construction column, and the lower part is connected to the main beam of the superstructure module body. In order to avoid stress concentration caused by different structural dimensions between the beam and the connecting column, the lower part of the connecting column is designed as a three-dimensional arc structure, as Figure 2 shown, and is connected by an arc gusset plate penetrating the bottom. Three vertical guide plates are arranged in the middle and lower parts of the main beam of the superstructure module body. The vertical guide plates correspond to the guiding structure and the general base guide plate to achieve the functions of positioning and position correction, and at the same time increase the local structural strength. A transverse connecting plate is arranged at the lower end of the upper module base interface and is connected to the transverse connecting plate of the general base interface to achieve the function of fixing the functional module. The guiding structure consists of four side plates inclined at 60 degrees to form a closed rectangular space. The size of the rectangular base is the same as that of the transverse connecting plate, serving as a transition device between the upper module base interface and the general base interface. The general base interface is arranged at the position of the longitudinal bulkhead and consists of a lateral reinforcing gusset plate, a vertical guide plate and a transverse connecting plate. The bottom is connected to the basic platform and the structure is strengthened.
