Background technology
Cage culture is the pith of marine economy, the gravity type net box (being called for short HDPE) that the hdpe pipe introduced by Norway at present makes develops rapidly, in the yellow Bohai Sea, the East Sea, the South Sea, have a large amount of raiser to use, this net cage is from introducing so far between recent two decades, and anchoring system is not all solved at all.The Qionghai fishing that the Oceanic and Fisheries Room, Hainan Province is signed and issued on December 1st, 2011 is done (2011) No. 198 literary compositions and is pointed out:
By the attack of No. 17 violent typhoon in 2011 " receive sand " and No. 19 typhoon " Ni Ge ", going to wreck property of our province deep-water net cage culture industry is hit, suffer heavy losses, 2050 mouthfuls are damaged in the whole province's 2601 mouthfuls of deep water mesh cages, wherein the disaster-stricken deep water mesh cage of about 70% is blown away because being destroyed fixed system by typhoon, the disaster-stricken deep water mesh cage of about 30% is damaged by stormy waves or sinks, lost units 2.1 ten thousand tons, direct economic loss 7.63 hundred million yuan.The deep water mesh cage of Lingao and Chengmai is almost annihilated, the 78.8% Oceanic and Fisheries Room, Hainan Province that the deep water mesh cage of Lingao loss accounts for the whole province's total amount is done (2011) No. 198 literary compositions in the Qionghai fishing on December 1st, 2011 and is pointed out, this is the consequence of engineering design technology shortcoming.
The dispatch of the Oceanic and Fisheries Room, Hainan Province points out that HDPE net cage is high at 12 grades of typhoons, 5m wave, under the sea conditions of 1m/s flow velocity, the 15m depth of water, the drag overall of single port net cage is about 8.31 tons, the drag overall of single group (4 mouthfuls) net cage is 33.25 tons, and single anchor line power is 8.13 tons.Anchor line is vertically stressed is 2.44 tons, and " the pile pulling power " that is produces under these conditions is 2.44 tons.According to the basic demand of net cage drag overall to anchor line power, derive safety requirements parameter when anchor, clump anchor, piled anchor three kinds of fixed systems 12 grades of typhoons respectively:
The safety requirements of the different anchorage style of table 1 deep water mesh cage
In realization, table requires and is not easy, and Hoe anchor 800kg adds that the iron chains of sufficient length just works, and one is expensive, and two is throw in difficulty.Clump anchor volume 1.5m
3weight 3.75 tons, drag little (ballast takes advantage of coefficient of friction) in mud, in addition thrown in all not easily to marine by land fabrication field, relate to and hang ship, installation fee is just high, the long 4.5m of piled anchor, stake diameter 40cm, vertical wedging, but this length, how does the stake of diameter beat? pile driving barge on energy? obviously can not afford.Therefore, there is the technical problem how realizing above-mentioned requirements.
Offshore oil is at mooring floating production storage unit (being called for short FPSO), namely store oil is collected, processing, outward defeated be integrated marine giant (the little then a few kiloton of ship tonnage, greatly then tens0000 tons) time, have employed another kind of mooring technology, wherein 2 or multipoint mooring most reference value, this is one ancients in essence " defeat a force with a tenderness " technology of philosophic theory, avoid " very stiff and demanding " powerful effective elasticity cushioning effect both reduced basic stress, also slow down the impact to buoyancy aid.CNOOC Zeng Hengyi Wu Si etc. are as far back as " two-point mooring gear " patent No. ZL95205025.0, and describing the float-type system pool being applied to floating production storage unit is System, just very unfortunate cage culture industry always no one study this technology.
This anchoring system principle is: the floating drum of huge buoyancy is fixed on by cable on the basis of enough withdrawal resistances, and buoyancy aid is as boats and ships, and the mooring of floating platform etc. is on floating drum, assuming that wind, wave, the mooring force produced under flowing common action, makes buoyancy aid produce and departs from, corresponding tilting complex torque is up time Needles direction, buoyancy then produces the righting moment in inverse time Needles direction, and the two is just in time reverse, and namely buoyancy can make it get back to equalization point by acting in opposition, thus realize dynamic equilibrium, the principle of compliant type balance that Here it is.In marine petroleum development, this principle is extensively successfully applied to engineering practice by oneself, typical in single point mooring, tension leg type platform etc., and in referenced patent document, listed several invention, applies this principle equally.
Inventor herein is according to the experience of presiding over ocean engineering exploitation for a long time in CNOOC, based on 2 of floating production storage unit (being called for short FPSO) or multipoint mooring theory, equipment itself is transformed, it is made to walk out offshore oil high-tech, the circle of high investment, realize practical, privatization, universalness, same mooring function is realized by our technology, same is safe and reliable, cost is only 1/10 of offshore oil construction, inventor herein granted patent " tree-shaped single point mooring system " patent No. ZL201420521171.4 realizes practical exactly, privatization, a kind of effort of universalness, this patent will be further improved on this basis, undoubtedly, our technology has meaning to current cage culture.
