Description

Technical Field

[0001] The utility model belongs to the technical field of marine platforms, and in particular relates to a combined adjustable DSF. Background Art

[0002] Traditional DSFs typically utilize either pure frames or flat skids. Pure frame DSFs have a limited dispersion length for support reaction forces, making it difficult to meet site load requirements. Conventional low-angle flat skids waste significant steel. Furthermore, due to the varying floatation heights and support spans of different platforms, DSFs must be individually redesigned and constructed for each project, resulting in high platform construction costs.

[0003] Therefore, it is urgent to design a combined adjustable DSF to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of the present invention is to provide a combined adjustable DSF, which has the advantages of saving steel consumption while solving the site bearing capacity problem, avoiding the need for site reinforcement, and solving the problems mentioned in the background technology.

[0005] To achieve the above objectives, the specific technical solution of a combined adjustable DSF of the present invention is as follows:

[0006] A combined adjustable DSF includes multiple sliding shoe assemblies, each of which is connected to a support frame. Adjustable short columns can be connected between the support frame and the sliding shoe assemblies. When the site bearing capacity meets the requirements, the height of the support frame can be changed by replacing the adjustable short columns of different heights to match the floatation height. When the site bearing capacity does not meet the requirements, the height of the sliding shoe assembly is increased to match the floatation height.

[0007] Furthermore, the sliding shoe assembly is a trapezoidal structure, and the angle between the waist edge of the sliding shoe assembly and the lower bottom edge of the sliding shoe assembly is 45 degrees.

[0008] Furthermore, every two adjacent sliding shoe assemblies are arranged along the first direction, and every two opposing sliding shoe assemblies are arranged along the second direction.

[0009] Furthermore, the plurality of sliding shoe assemblies are connected via a connecting frame.

[0010] Furthermore, the supporting frames are connected by pull rods, and the connecting frames are connected by pull rods.

[0011] Furthermore, the supporting frame and the connecting frame are connected via a pull rod.

[0012] Furthermore, the sliding shoe assembly is connected to the support frame via a pull rod.

[0013] Furthermore, the sliding shoe assembly includes multiple boot blocks, which are fixedly connected in sequence along the third direction. The multiple boot blocks are all trapezoidal structures, and the angle between the waist edge of the boot block and the lower bottom edge of the boot block is 45 degrees.

[0014] Furthermore, the lengths of the plurality of boots increase sequentially from top to bottom along the third direction, and the waist edges of the plurality of boots are located on the same straight line.

[0015] Furthermore, when the bearing capacity of the site does not meet the requirements, a shoe block is added to the bottom of the sliding shoe assembly to increase the height of the sliding shoe assembly.

[0016] The utility model has the following advantages: the length of the adjustable short column is determined according to the bearing capacity of the site. If the bearing capacity of the site is sufficient, the sliding shoe part can be fully utilized without the need for modification. The total height of the DSF can be matched by adjusting the height of the adjustable short column. If the bearing capacity of the site is insufficient, the adjustable short column can be shortened or cancelled, and the sliding shoe assembly can be raised to match the total height of the DSF.

[0021] 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 drawings in the embodiments of the present invention. Obviously, the embodiments described 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 creative work are within the scope of protection of the present invention.

[0022] Those skilled in the art will appreciate that, although some embodiments herein include certain features included in other embodiments but not other features, the combination of features from different embodiments is intended to be within the scope of the present invention and to form different embodiments. For example, in the claims, any one of the claimed embodiments may be used in any combination.

[0023] Please refer to the attached Figure 1 To the attached Figure 3 The present invention describes a combined adjustable DSF.

[0024] Traditional DSF generally adopts pure frame form and flat sliding shoe form: Figure 1 As shown in the figure, the dispersion length of the reaction force of the pure frame DSF support is small, and the site bearing capacity is difficult to meet the requirements; Figure 2 As shown, conventional low-angle flat skids waste significant steel. Furthermore, due to the varying floatation heights and pivot spans of different platforms, the DSF requires individual redesign and construction for each project, resulting in high platform construction costs.

[0025] Therefore, this combined adjustable DSF includes multiple sliding shoe assemblies 1, and the multiple sliding shoe assemblies 1 are connected to support frames 2. Adjustment short columns 4 can be connected between the support frames 2 and the sliding shoe assemblies 1. When the site bearing capacity meets the requirements, the height of the support frame 2 is changed by replacing the adjustment short columns 4 of different heights to match the total height of the DSF, so as to match the floating height. At this time, the height of the sliding shoe assembly 1 does not need to be changed. When the site bearing capacity does not meet the requirements, the height of the sliding shoe assembly 1 is increased to match the total height of the DSF, so as to match the floating height. At this time, a shorter adjustment short column 4 can be replaced or the adjustment short column 4 can be cancelled.

[0026] Specifically, the total height of the DSF is determined according to the offshore floating docking plan.

[0027] Specifically, when the site bearing capacity meets the requirements, an adjustment short column 4 can be fixedly connected between the support frame 2 and the sliding shoe assembly 1. When the site bearing capacity does not meet the requirements, the support frame 2 and the sliding shoe assembly 1 can also be directly fixedly connected.

[0028] Preferably, when the site bearing capacity meets the requirements, an adjusting short column 4 is welded and fixed between the support frame 2 and the slipper assembly 1. In other embodiments of the present invention, it can also be fixed in other ways, and when the site bearing capacity does not meet the requirements, the support frame 2 and the slipper assembly 1 can be directly welded and fixed. In other embodiments of the present invention, it can also be fixed in other ways.

[0029] The length of the adjustment post 4 is determined based on the site's bearing capacity. If the site's bearing capacity is sufficient, the skid assembly 1 can be fully reused without modification, and the length of the adjustment post 4 can be adjusted to match the overall height of the DSF. If the site's bearing capacity is insufficient, the adjustment post 4 can be shortened or eliminated, and the skid assembly can be heightened or lengthened to match the overall height of the DSF.

[0030] Moreover, the utility model can be disassembled, combined and reused, and can achieve platform adaptability to different fulcrum spans through low-workload transformation.

[0031] It should be noted that for reused structural parts, re-inspection is required, including inspection of corrosion, welds and appearance, and von Mises stress control is required for locations where non-destructive inspection cannot be performed on reused structural parts. It is recommended that the stress should not exceed 0.7 times the allowable value. The quality of welding inspections applied to new platforms must be strictly guaranteed. It is recommended that the number of DSF reuses be controlled within three times.

[0032] The shoe assembly 1 has a trapezoidal structure, and the angle between the waist edge of the shoe assembly 1 and the lower bottom edge of the shoe assembly 1 is 45 degrees, which saves steel and has sufficient bearing capacity of the shoe assembly 1. In other embodiments of the present invention, the shoe assembly 1 can also have other shapes, and the shoe assembly 1 has a trapezoidal structure, and the angle between the waist edge of the shoe assembly 1 and the lower bottom edge of the shoe assembly 1 can also be other angles.

[0033] Furthermore, every two adjacent sliding shoe assemblies 1 are arranged along the first direction A, and every two opposing sliding shoe assemblies 1 are arranged along the second direction B.

[0035] Furthermore, the multiple slipper assemblies 1 are fixedly connected via a connecting frame 3. Preferably, the multiple slipper assemblies 1 are fixed by welding via the connecting frame 3. In other embodiments of the present invention, other fixing methods may be used as long as the multiple slipper assemblies 1 can be fixedly connected to the connecting frame 3.

[0036] The supporting frames 2 are connected by the tie rod 5, and the connecting frames 3 are connected by the tie rod 5.

Preferably, the supporting frames 2 are fixed by welding with the tie rod 5, and the connecting frames 3 are fixed by welding with the tie rod 5. In other embodiments of the present invention, other fixing methods can also be used, as long as the supporting frames 2 can be fixedly connected to the tie rod 5 and the connecting frames 3 can be fixedly connected to the tie rod 5.

[0037] The supporting frame 2 and the connecting frame 3 are connected by a tie rod 5. Specifically, the supporting frame 2 and the connecting frame 3 are fixedly connected by the tie rod 5. Preferably, the supporting frame 2 and the connecting frame 3 are welded and fixed by the tie rod 5. In other embodiments of the present invention, other fixing methods can also be used, as long as the supporting frame 2, the connecting frame 3 and the tie rod 5 can be fixedly connected.

[0038] The slipper assembly 1 and the support frame 2 are connected by a pull rod 5. Specifically, the slipper assembly 1 and the support frame 2 are fixedly connected by the pull rod 5. Preferably, the slipper assembly 1 and the support frame 2 are fixed by welding through the pull rod 5. In other embodiments of the utility model, other fixing methods can also be used, as long as the slipper assembly 1, the support frame 2 and the pull rod 5 can be fixed.

[0039] Furthermore, the sliding shoe assembly 1 includes a plurality of boot blocks 11, which are fixedly connected in sequence along the third direction. The plurality of boot blocks 11 are all trapezoidal structures, and the angle between the waist edge of the boot block 11 and the lower bottom edge of the boot block 11 is 45 degrees.

[0040] Preferably, the plurality of boots 11 are welded and fixed in sequence along the third direction. In other embodiments of the present invention, the plurality of boots 11 may also be fixed in other ways.
