Background technology
Offshore Petroleum Industry is in the operation of exploitation coastal waters marginal oil field, a large amount of at present floating production storage unit (FPSO) or floating storage vessels (FSO) that adopt, this is the unconventional sea of a class buoyant means, these octagons or circular buoyant means, the same with conventional boats and ships, under the wave effect, the capital produces oscillating motion, the oscillating motion of the six-freedom degree of buoyant means, comprise along X, Y, the swing that moves axially and center on axle of Z axle, and the violent across the sea oscillating motion meeting of this buoyant means production brings adverse influence to offshore oil, such as allowing the seasick reduction work efficiency of people easily, simultaneously when the buoyant means oscillating motion is fierce, even the production safety of entail dangers to the buoyancy aid.
Summary of the invention
At the problems referred to above, the purpose of this invention is to provide a kind of simple in structurely, reduced investment does not reduce the marine float shake-reducing device of buoyancy aid functions of use.
For achieving the above object, the present invention takes following technical scheme:, a kind of marine float shake-reducing device, it is characterized in that: it comprises that a circle is near the rocker that subtracts that is provided with around the marine float bottom, the described L-shaped upwards pocket of outward flange that subtracts rocker rises, be arranged at intervals with one group of described stay bearing plate that subtracts rocker and buoyancy aid of connection on the rocker described subtracting, be arranged at intervals with one group of flow-disturbing mouth on the rocker near subtracting of described buoyancy aid one side, subtract rocker away from described buoyancy aid one side described and be provided with 1～3 road angle steel of aiding the strong.
The described bottom surface that subtracts rocker is concordant with described buoyancy aid bottom baseline.
It is described that to subtract the broadband that rocker stretches out described buoyancy aid be 1.5～3 meters.
Described stay bearing plate top is provided with top board, and its cross section is T-shaped.
Described stay bearing plate is provided with the opening of at least one expendable weight, is spaced apart 1.5～2.5 meters between the described stay bearing plate.
The length of described flow-disturbing mouth is 4～5 meters, and width is 0.4～0.6 meter.
The present invention is owing to take above technical scheme, it has the following advantages: 1, the present invention subtracts rocker owing to be provided with a circle around the bottom near buoyancy aid, therefore can increase the damping of buoyancy aid rolling, pitching, heave movement effectively, thereby reach the purpose that reduces the floating motion amplitude.2, the present invention is owing to be provided with stay bearing plate at interval subtracting on the rocker, therefore can provide the intensity that subtracts rocker effectively, owing on stay bearing plate, be provided with the opening of expendable weight, therefore when raising subtracts rocker rigidity and intensity, alleviated the whole weight that subtracts swing mechanism simultaneously.3, therefore the present invention can make vertical the flowing of fluid be disturbed owing to be provided with the flow-disturbing mouth in the inboard that subtracts rocker, has increased the damping of buoyancy aid heave movement effectively, and buoyancy aid up-and-down movement amplitude is more slowed down.4, the present invention has further strengthened the rigidity that subtracts rocker at exterior annular being provided with that the subtracts rocker angle steel of aiding the strong, and makes structure of the present invention more solid and reliable.The present invention is under the situation that does not reduce FPSO or FSO functions of use, make the working environment of personnel and mechanical equipment obtain tangible improvement, and the present invention uses conventional steel to make, have reduced investment, easy to process, be easy to realize that the present invention can be widely used in the various marine floats as a kind of effective means that reduces the oscillating motion amplitude.

The specific embodiment
Following structure drawings and Examples, the present invention is described in detail.
Embodiment one
As shown in Figure 1 and Figure 2, present embodiment buoyancy aid 1 is an octagon floating production storage unit (FPSO), around the bottom baseline 2 of octagon buoyancy aid 1 circle antirolling apparatus of the present invention is set.
Shown in Fig. 3～5, antirolling apparatus of the present invention comprises that a ring cross-section is the L type, subtracts rocker 3 with buoyancy aid 1 links into an integrated entity, along subtracting the stay bearing plate 4 that rocker 3 is arranged at intervals with one group of many booster action, stay bearing plate 4 is slightly triangular in shape, with subtract rocker 3 and buoyancy aid 1 is fixed into one.The horizontal surface clear width that subtracts rocker 3 is provided with one group of a plurality of flow-disturbing mouth 5, for strengthening subtracting the rigidity of structure of rocker 3, at the horizontal surface that subtracts rocker 3 in the outer part, the twice angle steel 6 of aiding the strong is set.
In the foregoing description, L shaped horizontal sides and the buoyancy aid welding that subtracts rocker 3, and concordant with buoyancy aid 1 bottom baseline 2, the vertical edges that the L shaped outward flange that subtracts rocker 3 rises for the pocket that makes progress, it can increase the intensity that subtracts rocker 3, increases to subtract rocker 3 traverse resistances.The width that the horizontal surface that subtracts rocker 3 stretches out buoyancy aid is about 1.5 meters～3 meters, the too little stabilizing efficiency of width is poor, the too big stabilizing efficiency of width increases not obvious, and structural strength is difficult to guarantee, therefore, subtracting rocker 3 width should try to achieve optimum value by hydrodynamic force software or model test, and subtracting rocker 3 main effects is the dampings that increase rolling, pitching, heave movement, thereby reaches the amplitude that reduces buoyancy aid 1 motion.
In the foregoing description, the spacing between each stay bearing plate 4 is about 1.5 meters～2.5 meters, and stay bearing plate 4 is provided with the perforate 41 that three expendable weights are used, and the quantity of perforate 41 can increase or reduce.The top of stay bearing plate 4 can be provided with the top board 42 of booster action, makes the cross sectional shape of whole back plate 4 T-shaped (as shown in Figure 5), and it has the effect that strengthens stay bearing plate 4 rigidity.The length that subtracts each the flow-disturbing mouth 5 on the rocker 3 is about 4～5 meters, width is about (such as 0.4～0.6 meter) about 0.5 meter, the effect of flow-disturbing mouth 5 is that vertical the flowing of fluid is disturbed, and to increase the damping of buoyancy aid 1 heave movement, makes buoyancy aid up-and-down movement amplitude retarded.Aid the strong quantity is set can changes of angle steel 6, more or less, operated by rotary motion 1～3 road.
Antirolling apparatus of the present invention is an all steel matter structure, at the marine float 1 that does not have speed of a ship or plane requirement, when building, just it is installed in the welding buoyancy aid, be the construction that makes things convenient for buoyancy aid 1 (FPSO) and the maintenance that lie up from now on, antirolling apparatus of the present invention is concordant around setting with buoyancy aid 1 bottom baseline 2, and allowing antirolling apparatus be not less than buoyancy aid bottom baseline 2, antirolling apparatus of the present invention does not have the daily attention requirement.
Embodiment two
Shown in Fig. 5～7, present embodiment buoyancy aid 1 is circular floating storage vessel (FSO), around the bottom baseline 2 of round-shaped float 1 circle antirolling apparatus of the present invention is set.
Antirolling apparatus of the present invention comprises that a plane is annular arrangement, subtracts rocker 3 with buoyancy aid 1 links into an integrated entity, subtracts also to be arranged at intervals with stay bearing plate 4 on the rocker 3, and flow-disturbing mouth 5 also is provided with the twice angle steel 6 of aiding the strong in the horizontal surface outside that subtracts rocker 3.
