Feature also cause it to hang down to swing response performance poor, need to improve.
Utility model content
In order to solve the technical problem swinging response performance difference huge, vertical of semisubmersible platform build in prior art, this practicality
Novel proposition one semi-submersible offshore platform, build to provide one to be prone to, hydrodynamic performance excellent, especially hanging down, to swing performance good
Good semisubmersible platform.It is achieved through the following technical solutions:
A kind of semi-submersible offshore platform, including floating drum, deck structure, many groups be supported between floating drum and deck structure stand
Post, described column is combined vertical pole, and combined vertical pole includes at least two root columns.
Preferably, the quantity of described combined vertical pole is four groups, and often group combined vertical pole includes 4 root columns, sub-column
Arrange rectangular.
Preferably, one or more layers is installed between described four root columns often organizing combined vertical pole and is parallel to deck knot
The heave plate of structure or connecting rod.
Preferably, described floating drum includes the first floating drum and the second floating drum be arrangeding in parallel with the first floating drum, two floating drums etc.
Big and be body structure, two groups of four groups of combined vertical poles are arranged on the first floating drum, and other two groups corresponding are arranged on the
On two floating drums.
Preferably, also including four horizontal braces, the two ends of four horizontal braces are connected to the first floating drum and second
Between the sub-column that floating drum is oppositely arranged, described horizontal brace is vertical with the first floating drum and the second floating drum.
Preferably, the inside of the first floating drum and the second floating drum is the subdivision structure with some chambers.
Preferably, described sub-column is cuboid, column cylindric, oval.
Preferably, height and the diameter of described each sub-column are the most identical.
This utility model has the advantage that relative to prior art: this utility model is by will to the transformation of platform column
Original big column is changed to include the combined vertical pole of at least two root columns, reduces the construction difficulty of platform and to building field
Ground, the requirement of equipment；Meanwhile, by setting up heave plate or bar linkage structure, add additional mass and the damping of platform, improve
The heaving performance of platform.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will be to embodiment
Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, the accompanying drawing in describing below is
Embodiments more of the present utility model, for those of ordinary skill in the art, in the premise not paying creative work
Under, it is also possible to other accompanying drawing is obtained according to these accompanying drawings.

Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings.
With reference to Fig. 1, this utility model semi-submersible offshore platform includes floating drum, is positioned at the deck structure 1 above floating drum, and
The combined vertical pole 2 being supported between floating drum and deck structure 1, combined vertical pole 2 of the present utility model includes at least two roots
Column: this utility model is by being changed to include the group of at least two root columns by original big column to the transformation of platform column
Box-like column, reduces the construction difficulty of platform and to build the side, the requirement of equipment.Described deck structure be combined formula stand
Post is supported, and is used for bearing top equipment load etc..
In order to reduce the construction difficulty of platform further and reduce build the side and the requirement of equipment, the present embodiment group
The quantity of box-like column 2 is four groups, and often group combined vertical pole 2 includes four root columns, the most sub-column A21, sub-column
The arrangement of B22, sub-column C23, sub-column D24, four root column is rectangular.Additionally, the present embodiment often organizes the son of combined vertical pole 2
Column quantity can also be three, or multiple.This four roots stem height can be identical with diameter.
In order to increase additional mass and the damping of platform, improve the heaving performance of platform, the often group group of the present embodiment
One or more layers heave plate 3 being parallel to deck structure, the 4 of heave plate 3 are installed between four root columns of box-like column 2
Individual angle can be tangential on the outer wall of four root columns.The sub-column of the present embodiment is cylindrical-shaped structure, it is also possible to for rectangular-shaped
Or ellipse column.In addition it is also possible to be provided with connecting rod between four root columns, owing to bar linkage structure is prone to the imagination, therefore in accompanying drawing
Not shown.
Floating drum of the present utility model can be a rectangle floating drum, is respectively provided with one group of combination type at the corner on floating drum end face
Column 2, additionally, the floating drum of the present embodiment is arranged to include the first floating drum 51 and second floats with what the first floating drum 51 be arranged in parallel
Cylinder 52, two floating drums etc. are big and are body structure, facilitate the construction of floating drum.Meanwhile, the two ends end face of each floating drum divides
Not being provided with two groups of combined vertical poles 2, two groups of combined vertical poles 2 are correspondingly arranged.In order to adjust the stability of whole ocean platform, this
First floating drum 51 of embodiment and the inside of the second floating drum 52 are the subdivision structure with some chambers.
For being further ensured that structural strength and the ability of opposing wave horizontal separation power, this reality of semisubmersible platform entirety
The horizontal brace 4 executing example is arranged between sub-column, i.e. the horizontal brace 4 of the present embodiment includes four, four horizontal braces
Two ends are connected between the sub-column that the first floating drum 51 and the second floating drum 52 are oppositely arranged, and horizontal brace 4 is with floating
Cylinder is vertical relation.Additionally, horizontal brace 4 can also be arranged between the first floating drum 51 and the second floating drum 52.
Above example is only in order to illustrate the technical solution of the utility model, rather than is limited；Although with reference to front
State embodiment this utility model has been described in detail, for the person of ordinary skill of the art, still can be right
