Description
Technical field
The present invention relates to offshore engineering equipment technical field, particularly relate to a kind of small-waterplane-area binary platform.
Background technology
Currently, three class basic forms can be mainly contained for very large floating structures type selecting, that is, box (also claiming plate type), semisubmersible-type and row's type.
Box-structure is height flat, closed, " plate of hollow " shape structure much smaller than span. The structure of box platform is simple, builds with the difficulty of assembling less, and cost is lower, and its drinking water is very shallow, it is possible to be arranged at waters, coastal waters. But, box-structure, because growing tall than very big, causes Rigidity and strength very low, therefore and have great coupling area between the water surface, all very big in Motion Waves response and load action response. In order to prevent, Wave Loads response is excessive, motion is too violent, structural distortion is excessive and causes structure deteriorate, need to enclose outside to put seawall, if being built in off-lying sea, then the quite high semisubmersible seawall of cost must be set in surrounding, therefore, simple, the cheap advantage of its structure will be largely reducing.
Semisubmersible-type structure is formed primarily of lower buoyancy aid, intermediate column and top platform, the lower buoyancy aid of semisubmersible-type structure is positioned apart from below horizontal plane certain depth under operation state, the column that it has waterlinearea very little, have much larger than the motion cycle meeting with wave period, thus resonance can not be produced with wave, there is satisfactory stability. Thus the exercise performance in wave is good. But, the main buoyancy aid of semisubmersible-type structure slips in water under operation state, and the interval between deck must much larger than the maximum wave height in marine site, place, and thus whole podium level is very big, and center of gravity height, causes dead load and water displacement all very big. In order to keep stable when operation, the semisubmersible-type vibrational power flow column of certain volume and cross section, body is thicker, comparatively small amt, causes wave loading more concentrated. In order to alleviate damage risk, overturning when preventing damage, need to be designed to large volume seal hatch by platform upper. These all will cause platform deadweight very big, and water displacement is very big, can cause again that mass force is big, wind wave action power is big, it is necessary to increases the reserve strength of structure, turn increases deadweight conversely. So, semisubmersible-type platform laid down cost is very high. In addition, it is installed and use operation quite complexity, increases use cost further.
Row's type structure is by multiple elongated pontoon dispersed placement and the buoyancy aid being fixed in same level and being formed.Row's type platform dutycycle is little, and spar diameter is little, and thus platform is little to the response of wave loading. There is the latent state of special half in higher wave, load response is insensitive to bigger wave height. Row's type structure platform is for meeting loading capacity requirement, and the floating drum number ratio that need to arrange is more, the resistance that the row's of which increasing type structure platform navigates by water when hiding typhoon, and maneuvering characteristics is poor. In addition, about location, row's type structure platform deep-sea, also there is no good terms of settlement at present.
