Under face 17, and not less than the lower edge on connection side 143.The anti-ice portion 141 of ice resistant structure 14 of the invention not only can to floating ice or
Ice sheet applies physical damage, and the lifting of ice resistant structure 14 can make the ice face of floating ice or ice sheet bend to fracture, to subtract
The impact force of frivolous ice or ice sheet.And the upper limb in anti-ice portion 141, lower than the upper limb on connection side 143, lower edge is not less than connection side 143
Lower edge so that bevel edge 145 tilts from top to bottom, bottom edge 144 tilts or horizontal from bottom to up, therefore trash ice can be along ice resistant structure
14 two sides, that is, bevel edge 145 and the movement on bottom edge 144 and drift about away, accumulated ice will not occur.In addition, trash ice is also made by gravity
With, via iceproof semisubmersible platform 1 heave movement and streaming the ocean current of platform column drifts away trash ice, prevent accumulation from being formed
Accumulated ice, avoids substructure, mooring system, dynamic positioning system and drilling well or production system is damaged.
Specifically, in the present embodiment, triangle is isosceles right triangle, connects side 143 and bottom edge 144 is isosceles right angle
Two right-angle sides of triangle, bevel edge 145 be isosceles right triangle bevel edge, two side, that is, bottom edges 144 in anti-ice portion 141 and tiltedly
Angle between side 145 is 45 °.In other embodiments, the angle on two sides in anti-ice portion 141 can also according to actual needs and
For other angles, more preferably range is 40 °~50 °, guarantees that anti-ice portion 141 had both had enough acutancees and destroyed ice sheet or floating ice,
Make the bevel edge 145 in anti-ice portion 141 and bottom edge 144 will not accumulated ice simultaneously.
Preferably to realize anti-ice effect, the ratio between the height of ice resistant structure 14 and the width of column 13 are 0.6~0.8.
In the present embodiment, connection side 143 upper limb be located at 3m on the work Water Plane 16 of iceproof semisubmersible platform 1~
4m, what the lower edge in anti-ice portion 141 was located at iceproof semisubmersible platform 1 deposits 2m~3m under Water Plane 17 certainly.In other embodiments,
The upper limb on connection side 143 is located at the distance on the work Water Plane 16 of iceproof semisubmersible platform 1 and the lower edge in anti-ice portion 141
It is set according to the needs of specific type of ship under Water Plane 17 positioned at iceproof semisubmersible platform 1 from depositing.
The upper end of column 13 is supported by deck box 11, and on deck, the center of box 11 is opened equipped with the moon pool for drillng operation
Hole is provided with drilling facilities on deck box 11.To avoid the drilling facilities in moon pool area from impacting by floating ice, iceproof semi-submersible type
The moon pool area of platform 1 is provided with standpipe protection structure 15.In the present embodiment, the lower end of standpipe protection structure 15 is located at iceproof
5m under the work Water Plane 16 of semisubmersible platform 1.In other embodiments, the lower end of standpipe protection structure 15 can also be it
His numerical value, as long as can guarantee that the lower end of standpipe protection structure 15 is located under the work Water Plane 16 of iceproof semisubmersible platform 1
?.In specific application, it is obtained to the movement progress sunykatuib analysis of floating ice according to actual sea area condition and is located at work
Position data under Water Plane 16.
Specifically, in the present embodiment, standpipe protects the shape of structure 15 in a circular table shape, and the angle of side and vertical plane is
10 °~15 °, the small end of rotary table is connect with deck box 11.Standpipe protects structure 15 after encountering floating ice, not only can protect drilling well
Facility, the side of rotary table and the design of vertical plane angle can also apply physical damage to floating ice.In other embodiments, standpipe is protected
The shape of protection structure 15 can also be prism-frustum-shaped or other shapes, as long as being able to satisfy the cross-sectional shape size of standpipe protection structure 15
It is cumulative from the upper end to lower end.
The upper surface of standpipe protection structure 15 is fixedly connected with the lower surface of deck box 11.In other embodiments, standpipe is protected
Protection structure 15 can also be protruded into deck box 11 and is fixedly connected again.
The lower end of column 13 is fixed on lower floating body 12, provides support force for the deck box 11 of 13 upper end of column.Specifically,
Lower floating body 12 is two and is arranged in parallel, and two vertical column 13 is respectively set on each lower floating body 12, is located at two lower floating bodies
On 12 and corresponding column 13 is connected by two stulls 18, and stull 18 is variable cross-section cylinder, intermediate thin along its own length direction
Both ends are thick.
In the present embodiment, stull 18 include two linkage sections, two changeover portions and an interlude, one end of two linkage sections respectively with
Column 13 is connected and fixed, and the other end of two linkage sections respectively passes through changeover portion connection interlude.Linkage section and interlude are
Cross section structure, and the section of linkage section is greater than the section of interlude, the section of changeover portion is successively decreased from linkage section to interlude.Anti-ice
The outer rim in portion 141 is located in changeover portion region in the projection in stull 18.The structure of stull 18 not only ensure that stull 18
Intensity and also make stull 18 have an inclined surface trash ice between ice resistant structure 14 and stull 18 can be floated along the inclined surface
Shifting skids off, and reduces accumulated ice.
As shown from the above technical solution, the advantages and positive effects of the present invention are: when iceproof semi-submersible type of the invention
When platform is impacted by floating ice or ice sheet, not only the anti-ice portion of ice resistant structure can apply physical damage to floating ice or ice sheet, but also
The lifting of ice resistant structure can make the ice face of floating ice or ice sheet bend to fracture, to mitigate the impact force of floating ice or ice sheet.It is broken
Trash ice after broken can be moved along the two sides of ice resistant structure and be drifted about away, and accumulated ice will not occur, will not be further to sub-aqua sport
Destroy submerged structure or critical system.Broken trash ice also passes through gravity, via the heave of iceproof semisubmersible platform
The ocean current for moving and streaming platform column drifts away trash ice, prevent accumulation forming accumulated ice, avoid substructure, mooring system,
Dynamic positioning system and drilling well or production system are damaged.
The above is only preferable possible embodiments of the invention, not limit the scope of the invention, all with the present invention
The variation of equivalent structure made by specification and accompanying drawing content, is included within the scope of protection of the present invention.
