Description
Technical field
This utility model relates to field of ocean engineering, a kind of single point mooring for ocean engineering
Buoyant means.
Background technology
Single point mooring refers to a mooring and rotating device, and it is (marine floating at submarine pipeline and mooring ship
Formula oil vapor treatment and storage device, oil tanker etc.) between provide one contact for conveyance fluid goods use,
Boats and ships can be to consolidate on it, and direct bearing boats and ships can rotate around mooring point under environmental load effect.Single point mooring
Device is called for short single point mooring, English " Single Point Mooring ", is called for short " SPM ".It is with marine
Oil field produce in early days and marginal oil field and grow up.
Single point mooring's buoyant means is mainly by floating drum, anchor chain component, mooring line component, flotation hose component
Constitute with underwater hose component.Floating drum ensures that device entirety swims on ocean surface, and by many in spoke
The anchor chain penetrating shape layout is connected in anchor or the stake in seabed, uses underwater hose between floating drum and seabed manifold
Component connects；Boats and ships pass through mooring line component mooring on floating drum.But current Single-point system buoyant means
In, floating drum is poor to the impact resistance of ocean current, causes the overall stability of single point mooring's buoyant means relatively
Difference, affects the service life of single point mooring's buoyant means, or adds the dimension of single point mooring's buoyant means
Protect cost.
Utility model content
For above-mentioned technical problem, this utility model designed and developed a kind of to ocean current impact resistance preferably,
The single point mooring's buoyant means for ocean engineering that fault rate is lower and service life is longer.
The technical scheme that this utility model provides is:
For single point mooring's buoyant means of ocean engineering, including:
Floating drum, it includes float body and annular section, and described float body is cylindrical, described ring
Shape part is sheathed on the bottom of described float body, and is positioned close to the position of the bottom of described float body
Putting, described annular section is to be surrounded by roof, diapire and sidewall to be formed, and described roof and described diapire are all
Being positioned on horizontal plane, the sidewall of described annular section is the conical surface, and described diapire is bigger than the width of described roof,
The inside of described annular section is separated into the multiple sealings relative to the distribution of the axisymmetrical of described float body
Storehouse.
Preferably, in the described single point mooring's buoyant means for ocean engineering, described annular section
Inside be separated into 6 gas-tight silos.
Preferably, in the described single point mooring's buoyant means for ocean engineering, described annular section
Diapire and the bottom of described float body between distance be 10cm.
Preferably, in the described single point mooring's buoyant means for ocean engineering, multiple chain stoppers set
Put the bottom margin at float body.
Preferably, in the described single point mooring's buoyant means for ocean engineering, described annular section
The base angle of shaft section of sidewall be 30 °.
Spar design is become floating drum by the single point mooring's buoyant means for ocean engineering described in the utility model
Main body, and an annular section it is provided with in the outside of float body, this annular section is positioned close to float
The position of bottom of cylinder main body, and the sidewall of annular section is a conical surface.Annular section add floating drum with
The contact area of ocean surface；When ocean current impact floating drum, ocean current can be along the wall flow of annular section, i.e.
Annular section contributes to reducing the impact of ocean current, adds the overall stability of single point mooring's buoyant means,
Reduce the ocean current destruction to single point mooring's buoyant means, and then improve the use of single point mooring's buoyant means
Life-span.
Accompanying drawing explanation
Fig. 1 is the structural representation of single point mooring described in the utility model buoyant means.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in further detail, to make those skilled in the art
Can implement according to this with reference to description word.
As it is shown in figure 1, this utility model provides a kind of single point mooring's buoyant means for ocean engineering,
Including floating drum 3, it includes float body 1 and annular section 2, and described float body is cylindrical,
Described annular section 2 is sheathed on the bottom 9 of described float body, and is positioned close to described float body
The position of bottom 8, described annular section for be surrounded formed by roof 4, diapire 5 and sidewall 6, institute
Stating roof 4 and described diapire 5 is all located on horizontal plane, the sidewall 6 of described annular section is the conical surface, institute
Stating diapire bigger than the width of described roof, the inside of described annular section 2 is separated into relative to described floating drum
Multiple gas-tight silos of the axisymmetrical distribution of main body.Spar design is become two parts to float by this utility model
Cylinder main body and annular section, wherein float body is consistent with the structure of floating drum of the prior art, for cylinder
Shape structure, it may have multiple gas-tight silos.Annular section is positioned close to the position of the bottom of float body,
So can increase the contact area of floating drum and ocean surface.It addition, the sidewall of annular section is the conical surface, i.e. from
Outline is seen, annular section is the shape of frustum, when ocean current impact floating drum time, ocean current can along sidewall to
Upper motion, this contribute to reduce the ocean current impact to floating drum, and then contribute to reduce ocean current floating drum is broken
Bad property, thus improve the stability of single point mooring's buoyant means.The inside of annular section is separated into multiple
Gas-tight silo rather than an overall gas-tight silo, when one of them gas-tight silo is destroyed, it is impossible to provides floating
During power, other gas-tight silos still can play a role.
Preferably, in the described single point mooring's buoyant means for ocean engineering, described annular section
Inside be separated into 6 gas-tight silos.
Preferably, in the described single point mooring's buoyant means for ocean engineering, described annular section
Diapire 5 and the bottom 8 of described float body between distance be 10cm.Annular section and float body
Bottom between retain certain distance, some auxiliary devices can be set at the near-bottom of float body.
Preferably, in the described single point mooring's buoyant means for ocean engineering, multiple chain stoppers set
Putting the edge, bottom 8 at float body, anchor chain is connected to chain stopper 7, and by single point mooring's buoyant means
It is fixed on the anchor in seabed.Owing to annular section is arranged on the whole of the bottom of float body, i.e. annular section
Body thickness will not be very big, when chain stopper is arranged on float body, and overall steady of single point mooring's buoyant means
Qualitative more preferably.
Preferably, in the described single point mooring's buoyant means for ocean engineering, described annular section
The base angle of shaft section of sidewall be 30 °.This angle is more suitable for eliminating the ocean current impact to buoyant means.
Although embodiment of the present utility model is disclosed as above, but it is not restricted to description and reality
Executing listed in mode utilization, it can be applied to various applicable field of the present utility model completely, for
For those skilled in the art, it is easily achieved other amendment, therefore without departing substantially from claim
And under the general concept that limited of equivalency range, this utility model is not limited to specific details and shows here
The legend gone out and describe.
