Description
Technical field
The utility model relates to a kind of buoyant tower platforms, belong to ocean engineering field.
Background technique
Buoyant tower platform is the platform for being used for acquisition and storage condensate or crude oil, and buoyant tower platform shape is similar
In SPAR platform, but what is be different from is that buoyant tower platform section structure extends to sea bed and by included shallow foundation
The suction pile of cylindrical type is fixed in seabed and with wave motion, and the big advantage of the one of buoyant tower platform is to be able to achieve from peace
Dress does not need auxiliary and transportation and erection equipment, easy for installation and disassembly, and transition may be implemented and reapply, but current buoyancy
Tower platform be it is a kind of fix total high platform, such as the platform that patent 2011800612002 and 2013104737690 is related to, such
Platform is applicable in the depth of water and cannot adjust, and transition, which reapplies, requires the depth of water to keep almost the same, and application range greatly suffers restraints, such as
Fruit adjusts the applicable depth of water using similar jack up equipment, this meeting so that platform cost leap, it is honest and clean to change buoyant tower platform
The original intention of valence.
Summary of the invention
Technical problem to be solved in the utility model is to solve existing buoyant tower platform only to adapt to single depth of water disadvantage.
To solve the above-mentioned problems, the buoyant tower platform of the utility model, including suction pile, first order tower body, described
Level-one tower body includes at least one cylinder, and it further includes second level tower body, institute that the bottom of first order tower body, which is arranged in, in the suction pile
The cylinder for stating second level tower body is corresponding with the cylinder of first order tower body, and the cylinder top center of the first order tower body is equipped with recessed
Slot is fallen into, recessed groove section specification and the pole section of second level tower body match, the cylinder lower part of the second level tower body
It is correspondingly embedded in the recessed groove on the cylinder of first order tower body, the top of the second level tower body is provided with superstructure.
Above-mentioned technical proposal advanced optimizes, and the first order tower body and second level tower body are single-column body or cylinders,
The cylinders is that at least two same specification single-column bodies are arranged in parallel and upper and lower side is in same level.
Above-mentioned technical proposal advanced optimizes, and the second level tower body is detachable, by replace different height second
Grade tower body can realize the change for being applicable in the depth of water.
Above-mentioned technical proposal advanced optimizes, and the second level tower body height is no more than 5 times of groove depth of recess.
Buoyant tower stage+module method, comprises the following steps described in above scheme, and first order tower body is lauched, by first
Grade tower body water filling, makes first order tower body sink, it is ensured that more than seawater surface, mobile first order tower body makes on first order tower body top
Its close to semi-submerged ship, by first order tower body be placed in semi-submerged ship go on board outboard bracket second level tower body underface, by first
Grade tower body draining, makes first order tower body float, recessed groove on first order tower body and second level tower body is embedded in and docked, then by buoyancy
Tower water filling makes second level tower body upper end to installation upper layer building height, installs superstructure in second level tower body upper end.
In above scheme, second level tower body height can be selected according to construction sea area depth.
The reverse process of above-mentioned installation method is exactly platform disassembling method.
The more existing buoyant tower platform of the buoyant tower platform of the utility model is adapted to the operation of different water depth sea area.
Detailed description of the invention
Fig. 1 is the utility model buoyant tower platform structure schematic diagram；
Fig. 2 is the comparison that existing buoyant tower platform and the utility model buoyant tower platform use different size second level tower body
Figure；
Fig. 3 to Figure 12 is the utility model buoyant tower stage+module process schematic.
Specific embodiment
The utility model buoyant tower platform embodiment is illustrated below with reference to Fig. 1, Fig. 2:
Existing buoyant tower tower body is made of single or multiple cylinders, is typically four column buoyant tower platforms, buoyant tower tower body circle
Rod structure is higher than Free Surface, that is, sea level 5, has lifted superstructure, but existing buoyant tower is a kind of total high platform of fixation, fits
The depth of water is not adjustable, and limits the range that transition reapplies.
As shown in Figure 1, buoyant tower platform, including suction pile 1, first order tower body 2, the suction pile 1 are arranged in the first order
The bottom of tower body 2, the first order tower body are four column structures, four cylinder be arranged in parallel by four same specification cylindrical bodies and
At, it is ensured that four cylindrical end faces are in same level.
It further include second level tower body 3, the second level tower body 3 is also four column structures, and four cylinder is also by four
Same specification cylindrical body is arranged in parallel, and ensures four cylindrical end faces in same level.
Four cylindrical body top centers of the first order tower body 2 are equipped with recessed groove, recessed groove section specification and the
The cylinder section of second level tower body 3 matches, and four cylindrical body lower parts of the second level tower body 3 are correspondingly embedded in first order tower
In recessed groove on four cylindrical bodies of body 2, the top of the second level tower body 3 is provided with superstructure 4.
As shown in Fig. 2, the adjusting for being applicable in the depth of water may be implemented by the second level tower body 3 of replacement different height, and not
It needs by expensive from liter system, this reapplies positive meaning in the transition of marginal oil field sea area for buoyant tower platform
Justice.
Referring to Fig. 3 to Figure 12, buoyant tower stage+module method:
A. buoyant tower and its superstructure 4 are by Ship Transportation partly latent, and wherein first order tower body 2 couches in boat deck partly latent
On, and second level tower body 3 and superstructure 4 are successively placed on a bracket 6, and can be slided on bracket 6,6 one sections of bracket
It extends on the outside of ship side；
B. semi-submerged ship dive, first order tower body 2 float, and towboat drags first order tower body 2 away from semi-submerged ship；
C. by 2 bottom water injection of first order tower body, first order tower body 2 is made to sink, pays attention to ensuring 2 top of first order tower body certainly
By 5 or more surface；
D. first order tower body 2 is pushed towards into semi-submerged ship, is placed in and is extended on semi-submerged ship under the bracket 6 on the outside of ship side；
E., second level tower body 3 is slid onto the surface of first order tower body 2 on bracket 6；
F. first order tower body 2 is drained and is floated, first order tower body 2 is docked with second level tower body 3 at this time, second level tower body 3
It is embedded in first order tower body 2, riveting is fixed；
G. first order tower body 2 is filled the water again, first order tower body 2 sinks at this time, pays attention to ensuring that tower body 3 top in the second level exists
5 or more Free Surface；
H., superstructure 4 is slid onto the surface of second level tower body 3 on bracket 6；
I. first order tower body 2 is drained and is floated, second level tower body 3 is docked with superstructure 4 at this time, and riveting is fixed；
J. entire buoyant tower is dragged to target water installation.
And the demolishing process of buoyant tower is exactly the inverse process of above-mentioned installation process, can facilitate realization transition by the above method
It installs again.
The limiting length of second level tower body 3 depends on structural strength and second level tower body 3 is embedded in first order tower body 2
Depth, the general total length for recommending second level tower body 3 are no more than 5 times of embedded length.
