Description
Affiliated technical field
The present invention relates to ship mooring mechanism, particularly a kind of liquid bulk cargo carrier offshore loading and unloading anchoring system and anchoring method are fit to the loading and unloading of liquid and loose unpacked material freighter and adopt.
Background technology
In the prior art, liquid or loose unpacked material freighter loading and unloading material mainly contain three kinds of mooring forms: first single point mooring unit, by six roots of sensation anchor chain at sea with a mooring buoy mooring, on floating drum, be provided with mooring arm and the oil transportation rotating head that to do 360 degree rotations around the floating drum center, be connected with the freighter bow and freighter links together by the mooring arm.This mooring gear has weather vaning capability, and is stressed little, reduced investment, and advantage such as production cycle is short, and is easy to use and safe and reliable, but deficiency is that to take the waters big, can't use in the waters that is restricted; It two is diffuse transmission type spread mooring devices, and it is the center with the mooring steamer, arranges chain cable combination mooring gear along circumferential scattering, and ship is carried out comprehensive constraint, and mooring mechanism is for hanging stored energy by the chain cable and the elastic deformation of chain cable produces restoring force.Its advantage is the accuracy of positioning height, and it is less to occupy the waters, reduced investment, and production cycle is short.But shortcoming is mooring arranges compactness inadequately, and mooring fast is easy to wear and tired, is to bother than single point mooring (SPM) from the pool operation; It three is fixed type harbours, and it is by stake or caisson works to be fixed in the seabed, and the mooring body of a rigidity is provided for ship; Its advantage is the loading and unloading operation facility, and shortcoming is to involve great expense, and leaning on has bigger risk from pool, and takies coastline resource.
Summary of the invention
In order to overcome the above-mentioned defective that existing liquid bulk cargo carrier mooring gear exists, the invention provides a kind of liquid bulk cargo carrier offshore loading and unloading anchoring system and anchoring method, adopt this mooring system and anchoring method thereof can save the waters, do not take coastline resource, reduce investment outlay, and easy to use, safety.
Task of the present invention realizes by this way: a kind of liquid bulk cargo carrier offshore loading and unloading anchoring system and anchoring method, it is characterized in that described mooring system by three the cover mooring gears form, described mooring gear is by floating drum, hang counterweight, seat end counterweight and anchor foundation are formed by connecting by linking part successively, the anchoring method of described mooring system is that every cover mooring gear is linked together floating drum and freighter by linking part, wherein two cover mooring gears lie in the liquid bulk cargo carrier bow, another set of mooring gear lies in the liquid bulk cargo carrier stern, and three cover mooring gears become the Y font to arrange.
Purpose of the present invention can also take following measure to realize:
Floating drum of the present invention can adopt steel plate to be welded, and also can adopt cored steel reinforced concrete and other floating material to make, and can keep afloat or immerse water surface etc. and have the member of force characteristics vertically upward when static.
Described suspension counterweight and seat end counterweight material therefor can be that ore in sand form or the river sand, stone, reinforced concrete block, metal piece etc. of packing have the member of action characteristic vertically downward.Seat end counterweight with metal piece or reinforced concrete block for well, can bear the seabed sandstone to seat at the bottom of the wearing and tearing of counterweight.
Described anchor foundation is the member that anchor, stake, pouring weight and seabed cast fixture etc. have the lateral confinement force characteristic, but with stake for well, its tightness is good.
The described part that links can be chain, cable, rope or bar.
Mooring gear of the present invention adopts the effect of floating drum to be to make mooring gear to be connected with liquid bulk cargo carrier, after the suspension counterweight is set, the application force vertically downward of whole mooring gear just strengthens, the stability of the freighter that has improved floating drum and linked and improve mooring property, adopt the base counterweight can reduce the uplift force of anchor foundation greatly, improve its fastness effectively and provide elastic space for adapting to the needs that move.Therefore, adopt mooring foundation of the present invention to have mooring stability preferably and restorability.Native system adopts three cover mooring gears, wherein two cover mooring gears and liquid bulk cargo carrier bow link, another set of mooring gear and stern link, three cover mooring gears become the Y font to arrange effectively freighter to be positioned on the offshore marine site, then by existing delivery duct with liquid (gas) attitude goods or solid-state goods in bulk (graininess or powdery) is transported to bank or seat transport equipment just can.
As everyone knows, coastline resource is a valuable natural resources, the deep water coastline resource is related to the extremely valuable very rare again strategic resource of national economic development and national defense construction especially, build large-scale oil transportation terminal with traditional fixed type harbour technology, having taken extremely valuable coastline resource, is a kind of great waste.
In economic development riverine, coastland such as Yangtze River Delta, Delta of the Pearl River basin rapidly, coastline resource can't bear victory or defeat, be difficult to bear the needs that continue development, research and develop and a kind ofly can save water area resource, and the offshore terminal technology that does not take water front is to support the needs of social economy's sustainable development.
The invention will replace traditional fixed type harbour technology with the offshore terminal technology; can reach and save construction investment, save coastline resource, save and take the waters, avoid or reduce navigation channel or berth excavation; avoid or reduce suspended matter periodically polluting; avoid or reduce disturbance and destruction hydrodynamic environment; can reach and fully to look after recent interests, investor's interests; can fully look after interests at a specified future date, social benefit again, the good effect of environmental protection demand and social sustainable development demand.The present invention compared with prior art has following characteristics particularly:
1. do not take coastline resource, can move and reuse, help sustainable development;
2. it is little to take the waters, saves water area resource, helps realizing building a resource-conserving society;
3. be easy to restore and planning again, do not stay or stay obstacle less, be convenient to the utilization again of resource;
4. can avoid or reduce the excavation in navigation channel and berth according to Natural Depth condition flexible arrangement, help reducing investment outlay;
5. the suspended matter of avoiding or reduce the excavation in navigation channel and berth to cause pollutes, and helps environmental protection;
6. plant bulk is little, reduces destruction and influence to the untreated water dynamic environment, helps the stable of navigation channel;
7. adopt the contactless hawser of elasticity floating drum to connect, reduce collision risk, reduce the risk of oil spill;
8. comparatively convenient, the safety of operation is reliable;
9. investment economizes most, production cycle is the shortest;
10. the application region is more extensive, can be used for coastal waters, bay, rivers, lake;
11. can play positive progradation to the loading and unloading of liquid bulk goods transportation, reduce construction investment and shipping and delivery cost, the development of the sustainer-energy transport undertaking of national economy is played the effect of actively promoting.
