Description
Technical field
The present invention relates to a kind of marine fishing ground platform, especially a kind of netted modularization sea fishing ground platforms.
Background technique
Since nineteen eighty, the annual output of aquaculture has increased about 10%, this is making up sea food supply and demand gap
Aspect plays critically important effect.Currently, most of fishing grounds are in coastal masking sea area, coastal area is suitable for the place breeded fish
It is fewer and fewer, and excessively cultivation is damaged to coastal ocean environment.In order to meet eating to marine products for whole world growth
The demand and expansion culture fishery of object, new fishing ground is forced ocean without shielded area.
Using the most practical most common cultural technique of the open aquaculture tank of flexible floating ring, and it is several recently
This technology has been achieved with significant progress within 10 years.Entire cultivating system generally includes floating ring, fishnet, bottom ballast, mooring
System etc..Floating ring is usually (HDPE) made by highdensity polyethylene, they may undergo big vertical movement, water
Dynamic effect and the interference of strong wave structure, these influences will lead to the fatigue and destruction of floating ring.Fishnet is in water flow
Large deformation be another main problem that open net cage system faces, the various biologies accumulated on fishing net further increase
The deformation of fishnet is added, biofouling bring additional drag also affects the load of anchoring system and further results in net cage
Structure is destroyed.
Fishing ground, which is installed to no shaded areas, has many benefits, including a large amount of space to expand scale, huge sea
Water delivered payload capability, reduction conflict with numerous users', reduce the contact to mankind's pollution sources and reduce negative environmental consequences
Potentiality.However, by study the problem of discovery before it is found that using flexible floating ring and fishnet traditional open net cage not
Suitable for the severe environmental conditions without masking sea area, novel strong marine fishing ground is needed to cope with this challenge.
In order to improve seafood yield, several potential new fishing ground concepts for off-lying sea have been proposed in the world.With
Unlike the toughness floating ring that operation fishing ground uses at present, new concept selection keeps out rugged environment using rigidity supporting structure
Load.
SalMar ASA constructed one rigid semi-submersible type fishing ground " marine fishing ground 1 ", the design is by aquaculture
The technology in field in conjunction with exploitation of offshore oil and gas technology together.The design includes the same bracket of fence, elemental floating body with
An and loose anchoring system.Fishnet is tightened up and is fixed on bracket and deforms to avoid in water flow.The testing equipment is pre-
Meter will be installed the second half year in 2017 in Central Norway coastal area.
Norway Royal Salmon AS and Aker Solutions ASA proposes another for without masking sea area
Rigid semi-submersible type fishing ground, it contains there are two floating drum, with vertically connecting with diagonal bracket between floating drum.The net cage in the fishing ground is complete
It immerses entirely marine to avoid the huge seaway load for leaning on approximately level, and devises a underwater air bag to provide air.It needs
It is pointed out that this conception of species has used traditional gravity net cage, net cage keeps volume by bottom ballast in this.This net cage exists
The deformation ratio shaded areas met in the high-velocity flow of no shaded areas is bigger.This may threaten the health of fish.In addition to this,
The use of underwater air bag can also meet with challenge.
Nordlaks AS proposes that there is a wind vane single point mooring system in a kind of ship shape fishing ground, the fishing ground.The fishing ground can be with
It is rotated in various environment directions around stem.Such system increases the spread scope of fish resource waste, reduces and feels
A possibility that dye.However, " Havfarm " theory may meet with following challenge.Wind direction mark system allows structure stem in majority
Towards water flow and wave in environmental aspect.The net cage in downstream may reduce water coke slurry than the net cage of upstream because entire fishing ground has
Multiple net cage column are in a row, and the distance between they very little.Therefore, the net cage dissolved oxygen levels in downstream can be lower and increase
Waste this may seriously affect the health of fish.To improve water coke slurry, fishing ground can be made to water flow using dynamic positioning system
Inclination, but this can increase significantly energy consumption and operation and maintenance cost.
In addition to open net cage scheme, closed fishery is had also been proposed in someone.Marine Harvest Norway AS
" oval fishing ground " is proposed together with Hauge Aqua AS.The design is mainly in view of in such a closed in spaces, ring of surviving
Border is easier to control.Therefore a possibility that extra large lice infection, is expected to smaller than open case net.Fish escape can also be to avoid.However,
Due to the complexity of control system and cabin structure itself, the cost in this oval fishing ground will be very high.Further, since its is huge
Enclosure space and water plane area, ovum type structure can suffer from huge environmental load and internal impact, therefore be difficult to
Without masking sea area.
It is continued to bring out in conclusion current sea fishing ground is especially the new configuration in far-reaching extra large fishing ground, however, various novel fishing grounds
Each there are some problems in structure, such as lower using sea situation, and construction is higher with maintenance cost, and environment is unfriendly etc..Therefore,
One kind is needed to can satisfy high sea situation, construction transportation cost is low, facilitates laying, novel marine fishing convenient for safeguarding, environmental-friendly
Field platform.

Articulated mounting 11 is convenient for handling, it can be achieved that conveniently assembly and disassembly between module, are easy to use smaller
Towboat or cargo ship reduce operation cost.This conception of species is also beneficial to fishing ground maintenance.Individual module can be disconnected fortune
It ashore repairs, and will not influence the operation in fishing ground.Module in each use can be replaced by new module.Just
For fish welfare, disconnecting for module fast and flexible can be to avoid the transmission between net cage 7.
In conclusion the platform is primarily based on grid structure with excellent water penetration, structural strength and sea-keeping, this is flat
Platform grid structure 1 and each ball of net cage 7 can be considered a particle in wave, make rail circular motion with wave, therefore it is to wave
It is slow in reacting, keep carrier position of centre of gravity downward as far as possible by adjusting ballast, it is high to increase carrier metancenter, therefore the platform stability and resistance to
Wave is splendid；Making platform integrally using single point mooring system can be freely rotated with wave with current direction altered, accelerate
The exchange cycles speed of seawater inside and outside fish pot is conducive to improve fish pot breeding environment；Bulb spacing structure is convenient for arranging net, while just
In the cleaning and maintenance of net；Fish pot quadrangle forms octagon using chamfer design, is more nearly shoal of fish parade habit, can also reduce
Material reduces construction cost；Modularized design reduces platform construction, transport and installation cost, enhances the spirit of fishing ground laying
Activity, convenient for daily maintenance and maintenance.A kind of netted modularization sea fishing ground of the invention platform may be implemented in 9m wave height without screening
Cover sea area safe operation, have the characteristics that low cost, maintain easily, be environmental-friendly, space utilization rate is high, laying is convenient, flexible,
New configuration scheme is provided for the marine fishing ground in far-reaching sea.
Finally it should be noted that above example is only used to illustrate the technical scheme of the present invention and not to limit it.Although referring to reality
Example is applied to describe the invention in detail, those skilled in the art should understand that, to technical solution of the present invention into
Row modification or equivalent replacement should all cover without departure from the spirit and scope of technical solution of the present invention in right of the invention
