Specific embodiment
1-2 with reference to the accompanying drawing, specific embodiments of the present invention will be described in detail, it is to be understood that of the invention
Protection scope is not limited by the specific implementation.Based on the embodiments of the present invention, those of ordinary skill in the art are not having
Every other embodiment obtained under the premise of creative work is made, shall fall within the protection scope of the present invention.
As shown in Figure 1, a kind of offshore platform provided by the invention buffers HSE ring with wave, comprising: multiple scalable anti-waves
Hose 1, multiple ring flanges 2 and multiple fixed devices 3, the ring flange 2 are located at the end of scalable anti-wave hose 1, and adjacent two
A ring flange 2 is bolted, the end to end composition HSE ring of multiple scalable anti-wave hoses 1, the multiple fixed device 3
It is located on scalable anti-wave hose 1, one end of fixed device 3 is connect with scalable anti-wave hose 1, the other end of fixed device 3
It is fixed on seabed.
Further, the tube wall of scalable anti-wave hose 1 is made of transparent material, the inside dress of scalable anti-wave hose 1
There is seawater, seawater breeding has seaweed.
As shown in Fig. 2, further, scalable anti-wave hose 1 is double-layer structure, it is to be tightly connected between two layers.
Further, air bag 4 is equipped in multiple scalable anti-wave hoses 1 at ring flange 2, air bag 4, which is equipped with, to be filled
Gas end 5, inflatable end 5 are located at the outside of scalable anti-wave hose 1.
Further, the length of scalable anti-wave hose 1 is 10-2000m, diameter 1-50m.
Further, fixed device 3 is the double earth anchors for being connected with fixed rope.
Further, the tube wall of multiple scalable anti-wave hoses 1 is made of PC transparent plastics material, the scalable anti-wave
The seaweed cultivated in hose 1 is cyanobacteria.
Further, ring flange 2 is made of organic glass.
In the analysis of marine structure object, through constructing model frequently with slender cylinder, the derivation of Morison equation is also based on
Cylindrical body analysis.
Compared with the wavelength X of wave incidence wave, the diameter D of flotation hose is larger, therefore, it is considered that the presence meeting of flotation hose
Wave motion is had an impact, wave is mainly shown as viscid effect and virtual masseffect to the effect of hose.Flotation hose
Be in cylinder morphology under full state, since the density of sea water relatively interior pumped (conveying) medium of pipe is big, when being completely submerged under seawater by
The buoyancy arrived is greater than self gravity, therefore hose floats across the sea always, and only fraction is immersed in seawater, such as Fig. 3 institute
Show；
As shown in figure 4, θ indicates the line and vertical direction of sea level and pipe intersection point connecting tube mass center itself in Fig. 4
Angle, h indicate b.s.l. height, and r indicates pipe shaft radius.Pipe by wave force, ocean current power, wind-force, pipe and oil from
The load such as body gravity and buoyancy, pulling force establish local coordinate system XOZ in pipe mass center, carry out force analysis to it, according to by
Dynamic balance is it is found that must meet following relationship between various load.
Relational expression:
F is floating=and G fills+G pipe,
F drawing=F wave+F ocean current+F wind.
Pipeline vertical direction stress balance, so that
SL1ρ=π (D/2-d1)2L1ρIt fills+π[(D/2)2-(D/2-d1)2]L1ρPipe (1)
In formula: L1For hose unit length；ρ fills for filling liquid density；ρ pipe is Pipes Density；d1For hose thickness.
Projected area of the unit pipe range displacement of volume on tube section can be acquired by above-mentioned formula.
Therefore, it acts on and streams inertia force f on flotation hose1' may be expressed as:
By the geometrical relationship in Fig. 4, it is known that hatched area S may be expressed as:
In formula: R=D/2.Joint type (2) and (4) can solve height h to get unit pipe range displacement of volume is arrived in ocean current side
To projected area S.

It is sent in the accumulating system on platform.By algae culturing inside HSE ring, sunlight penetrates transparent tube wall, and seaweed is made to carry out light
Cooperation is used, and meets the demand of the platform life low tension of platform, and safer；
Combustion power generation can also be carried out to the algae later period simultaneously, recycle dioxy using three-dimensional light reaction incubator
Change carbon, production algae algae powder carries out firing hot power generation as biomass fuel, algae powder by burning.
The algae cultivated in scalable anti-wave hose can be used for later period progress combustion power generation, utilize three-dimensional light reaction incubator
Carbon dioxide is recycled, production algae algae powder carries out firing hot power generation as biomass fuel, algae powder by burning.
Cyanobacteria has the growth characteristic of general algae: its growth period is about 30 days, optimum moisture content 90%, entire raw
The life period can divide three phases: growth period, peak period, aging period.
4 cyanobacteria moisture content of table and time-to-live relation table
| Moisture content | 15% | 30% | 45% | 60% | 75% | 90% |
| Time-to-live | 3 days | 5 days | 8 days | 13 days | 20 days | 30 days |
After ocean platform removal of home, if also with original HSE ring and its seaweed of the inside, it can be according to the shipping time
Influence with shrinkage degree to transport, and combine upper table, it can be deduced that by the percentage of seawater extraction volume in pipe.
To sum up, offshore platform of the invention buffers HSE ring with wave and has the advantage that
1) multiple scalable anti-end to end composition HSE rings of wave hose, HSE ring float on sea, drilling platforms are surrounded,
Wave is converted into the impact of barrier formula to the direct impact of platform column, impact dynamics is efficiently reduced, to increase
