Description
Technical field
The present invention relates to marine engineering equipment field, especially a kind of offshore platform shoe.
Background technique
Ocean platform offshoreplatform is at sea to carry out drilling well, oil recovery, transporting something containerized, observation, navigation, construction etc. to live
It is dynamic that the structures of production and living facilities are provided.
Fixed, movable two class can be divided by its architectural characteristic and working condition.The lower part of fixed platform is by stake, expansion
Big footing or other constructions directly support and are bonded to seabed, are divided into pile foundation type and two kinds of gravity type by bearing situation.It is movable
Platform floats in water or is supported on seabed, can move to another well location from a well location, and bottom formula and floating can be divided by connecing bearing situation
Two class of formula.Novel semi-fixed type ocean platform is being studied in recent years, it can be fixed in deep water and high movable,
Tension leg type platform belongs to such.
It is most representative with jack-up unit in movable ocean platform, self-elevating drilling platform be also known as deck lift or
Spud leg formula platform.This oil drilling device loads drilling machinery, power, equipment, accommodation on the platform kept afloat
And several liftable spud legs, when drilling well spud leg bottom, platform then lift away from sea certain altitude along spud leg；Platform drops when displacement
To the water surface, spud leg is risen, and platform can be dragged it by tugboat just as barge and move on to new well location.The advantages of jack-up unit, is main
It is that required steel are few, low cost, drillng operation can be smoothly carried out under various sea situations；The disadvantage is that spud leg limited length, makes
Its operating depth is restricted, and maximum operating depth is about in 120m or so.More than this depth of water, the increase of spud leg weight quickly,
When towage when spud leg rise very high, it is all unfavorable to platform stability and spud leg intensity.
Existing cylindrical leg is not easy to assemble, and space utilization rate is low, and integral strength is lower, and there are stress concentrations to ask
It inscribes, there are cracking or breaking security risk topics in use process.

It answers, the floor 510 is contained in the welding groove 330, and the floor 510 and welding groove 330 are used for coaming plate 500 and central platform
Welding between plate 300.Base section 410 is fixedly mounted in shoe portion 100, since the width of base section 410 is wider, so
It as much as possible can be connected to 100 internal structure of shoe portion in shoe portion 100, make inside base section 410 and shoe portion 100
Structure be capable of fixing and be integrated；And the structure of guide section 420 and the guide section 420 in shoe portion 100 are consistent, by guide section
420 be arranged to the consistent shape in shoe portion 100, convenient for the assembly in shoe portion 100 and spud leg seat 200；And by guide plate 400
After modularization, it is convenient for volume production.The floor 510 being arranged on the coaming plate 500 enhances the structural strength of coaming plate 500, makes coaming plate 500
With preferable intensity, since coaming plate 500 is connect with guide plate 400, and shoe portion 100 can be generated after by load it is certain
Deformation since coaming plate 500 has preferable structural strength, is unaffected in this case；In addition, the section of floor 510
To be T-shaped, welding groove 330 and rib cooperate, and can be welded in the case where not influencing coaming plate 500, furthermore, floor
510 increase the contact area between welding groove 330, effectively raise the soldering reliability of lamina tecti and coaming plate；And
The cross sectional shape of welding groove 330 can also be arranged to T-shaped.
In addition, it is in octagon that the bottom plate 120, which is overlooked, the bottom plate 120 includes bottom 121 and four side walls 122, described
Bottom 121 be it is rectangular, the bottom end of the side wall 122 is all connected to the side of the bottom 121, the two sides of the side wall 122 and phase
Interconnection is connected into four sides side wall, and the top of the side wall 122 is respectively positioned on same plane；The spud leg seat 200 is fixedly installed in described
The bottom 121 of bottom plate 120.Bottom plate 120 makes the bottom of spud leg can be sufficient with seabed surface after lower stake in standing shape setting
Contact, to keep ocean platform more stable after lower stake, in addition, side wall 122 and bottom 121 are arranged to have after concave shape to finish
Structure line be deformed bottom plate 120 will not easily.
In addition, further including single partition 700, the single partition 700 is fixedly connected between two oblique baffle assemblies 600, institute
The side that 700 inner face of single partition is fixedly connected with two guide plates 400 is stated, the single partition 700 is fixedly connected on the bottom plate
120 and top plate 140；It further include middle component 800, the baffle assembly 810 that encloses includes main demarcation plate 811 and small demarcation plate 812, institute
It is in a strip shape to state main demarcation plate 811, the main demarcation plate 811 is equidistantly vertically fixed with small demarcation plate 812, the main demarcation plate
811 and the small demarcation plate 812 offer hole；The middle component 800 encloses baffle assembly 810 by multiple groups and is interconnected to constitute,
800 6 face of middle component is individually fixed in the bottom plate 120, lateral coaming plate 130, oblique baffle assembly 600,700 and of single partition
Top plate 140, the middle component 800 are equipped with no less than four.
It wherein, further include lamina tecti 340, the lamina tecti 340 is in isosceles triangle shape, and 340 bottom edge of lamina tecti is set
There are multiple welding grooves 330, the welding groove 330 is sheathed on the floor 510, and the lamina tecti 340 is equipped with four pieces, the top cover
Plate 340 is fixed in the interval of the grid spacer component 150.The setting of lamina tecti 340 makes between grid spacer component 150
Cavity is sealing, will not be intake, since bottom 121 is used as stress concentration point, so the abrasion being subject to is stronger, if internal exist
Ponding then be easy to cause the multiple consumption of internal corrosion and abrasion, and inside is not easy to maintain relative to outside, so using top
Cover board gets up the cavity capping between grid spacer component 150.
In addition, 300 center of central platform plate offers pipeline mounting hole 350；300 surface of central platform plate is solid
Surely the first stiffening plate component 360 and the second stiffening plate component 370 are equipped with；The first stiffening plate component 360 is compassingly set at institute
