The technical scheme that adopts: oil storage and outer communication system in the water of a kind of deep-sea are provided; Comprise petrol storage tank 10 in the water, tension cables 3, pile foundation 4, oil inlet hose 12, oil hose 14; Petrol storage tank 10 is positioned at the sea 26 times in the said water, its through tension cables 3 moorings on the pile foundation that is positioned at sea bed 27 4; Oil inlet hose 12 1 ends are connected with the sea floating production facility, and petrol storage tank 10 is connected in the other end and the water; Petrol storage tank 10 is connected in oil hose 14 1 ends and the water, and the other end is connected with shuttle tanker 30.
Wherein, oil storage further comprises with outer communication system in the water of deep-sea: SAH 15 and mooring cable 16; SAH 15 is arranged at the top of petrol storage tank 10 in the water; Mooring cable 16 1 ends are connected with SAH 15; The other end is connected with shuttle tanker 30; Oil hose 14 1 ends are connected with SAH 15, and the other end is connected with shuttle tanker 30, and the length of mooring cable 16 is smaller than the length of oil hose 14.
Wherein, floating on the sea 26 have two types of navigator fix floating drums, navigator fix floating drum A and oil hose 14 and mooring cable 16 bonded assemblys; Navigator fix floating drum B and oil inlet hose 12 bonded assemblys, the navigator fix floating drum is provided with the navigation signal lamp.
Wherein, petrol storage tank 10 is positioned at the 26 times 50-150m in sea in the water.
Beneficial effect: 1, the utility model is oil storage and an outer communication system in the water of a brand-new generation, and the mooring of petrol storage tank tension force is on sea bed in the water, and it is little influenced by place, sea stormy waves power, and safety is high with stability, is suitable for the severe sea condition operation under abyssal environment; The risk of having got rid of petrol storage tank collision in shuttle tanker and the water simultaneously.
2, the utility model is peeled off oil storage system from the floating production facility of existing sea, has simplified the design and construction difficulty of existing sea floating production facility, thereby has reduced the laid down cost of sea floating production facility.
3, the operating procedure of the utility model crude oil exporting operation is easy, heaving pile, untie the mooring rope and the work of folding and unfolding flexible pipe all easy.
Description of drawings
Fig. 1 is the integral structure scheme drawing of oil storage and outer communication system in the water of a kind of deep-sea of the utility model.
Fig. 2 is the integral structure scheme drawing of oil storage and outer communication system operation in the water of a kind of deep-sea of the utility model.
The specific embodiment
The embodiment that below in conjunction with accompanying drawing with the tension leg platform is the sea floating production facility is elaborated to the utility model.
Accompanying drawing sign: 3-tension cables, 4-pile foundation, petrol storage tank in the 10-water, 12-oil inlet hose, 14-oil hose; The 15-SAH, 16-mooring cable, 17-navigator fix floating drum A, 18-navigator fix floating drum B; The 26-sea, 27-sea bed, 30-shuttle tanker, 35-tension leg platform.
Oil storage and outer communication system in a kind of deep-sea water of the utility model; Comprise petrol storage tank 10 in the water, tension cables 3, pile foundation 4, oil inlet hose 12, oil hose 14; Petrol storage tank 10 is positioned at the sea 26 times in the water; To avoid the turbulent region under the sea 26, make petrol storage tank 10 in the water receive the influence of the huge stormy waves power in coastal waters face 26 places hardly simultaneously, for the storage and the outer transporting operation of crude oil provides a relatively steadily safe working environment; On the pile foundation that is positioned at sea bed 27 4, petrol storage tank 10 carries out tensioning through the surplus buoyancy that presets to tension cables 3 to petrol storage tank 10 in the water through tension cables 3 moorings in the water, thereby makes that petrol storage tank 10 has exercise performance preferably in the water.The number of tension cables 3 can be three or the six roots of sensation; Confirm according to the profile of petrol storage tank in the water 10 and relevant designing requirement; Accompanying drawing 1 and accompanying drawing 2 are located for adopting in three tension cables 3 and 4 pairs of water of three pile foundations petrol storage tank 10 to carry out mooring, are clarity only drawn two tension cables 3 and two pile foundations 4.Oil inlet hose 12 1 ends are connected with tension leg platform 35, and petrol storage tank 10 is connected in the other end and the water; Petrol storage tank 10 is connected in oil hose 14 1 ends and the water, and the other end is connected with shuttle tanker 30.
