Description
Technical field
The utility model relates to a kind of anchor fitting, particularly a kind of be applied to novel semisubmersible oil production platform wet haul defeated in temporary fastening device between two buoyancy tank.
Background technology
When semisubmersible oil production platform is after shipyard has been built, need to be transported to operation marine site, generally had two kinds of methods: for short range transport, can directly have been drawn to operation marine site by tugboat, namely wet and drag; For middle and long distance transport, be then first transported to the more shallow harbour of refuge of the depth of water near operation marine site (namely dry drag) by carrier, then be dragged to operation marine site by tugboat is wet.Visible, no matter which kind of method, wet and drag the process of being absolutely necessary.For conventional semisubmersible platform, its hull structure comprises column, buoyancy tank and stull, and these structures were closed up in the shipyard construction phase, and hull structure forms an entirety, can overall towage go out.In recent years, based on new engineering demand, domestic and international company proposes series of new semisubmersible platform concept, is generally increase accessory structure below conventional semi-submerged platform buoyancy tank, such as, hang down and swing plate, truss, second layer buoyancy tank etc.For reducing wave load, the drinking water of these accessory structures is comparatively dark, and is limited by the restriction (being generally no more than 14 meters) of shipyard harbour drinking water, and these accessory structures cannot be welding as one with main body when dispatching from the factory, and need to install to sea.
For unconditional stability equipped deep-draft floating production platform, together with in the middle part of it, annular buoyancy tank (namely going up buoyancy tank) and small bore column, base circle ballast tank (namely playing buoyancy tank) were not brought together in construction phase and towage stage, need to assemble again to sea.When the wet haul of platform is defeated, upper buoyancy tank will be placed on above lower buoyancy tank.After arriving job position, then the two is connected together by certain way.In order to reduce the construction operations such as afloat welding, application as far as possible, needing to adopt temporary fixing structure between upper buoyancy tank and lower buoyancy tank, the relative motion of both control in towage process, reducing the coating material breakage of colliding and causing, even structural damage.On the other hand, because offshore construction window is limited, the temporary fastening device adopted should be convenient to dismounting as much as possible.
Utility model content
The utility model carries out to solve the problem, and object is to provide a kind of different scale that is adapted to be connected with the buoyancy tank of shape, and structural safety reliability is high, and cost is low, the temporary fastening device that offshore construction is easy.
The temporary fastening device that the utility model provides, for novel semisubmersible oil production platform wet haul defeated in upper buoyancy tank and lower buoyancy tank between, there is such feature, comprising: several base constructions, above the flying deck being arranged on lower buoyancy tank; Latch structure, with base construction one_to_one corresponding, below the underdeck being arranged on buoyancy tank, the top of base construction; Lower internal thread component, is fixed on the side of base construction; Upper internal threaded component, is fixed on the side of buoyancy tank, directly over lower internal thread component; And thru-bolt, two ends are mutually permanently connected with lower internal thread component and upper internal threaded component respectively, and wherein, base construction, central authorities have perforate, and latch structure inserts in perforate.
The temporary fastening device that the utility model provides, also has such feature: wherein, and the size of perforate is greater than the size of latch structure.
The temporary fastening device that the utility model provides, also has such feature: wherein, and the shape of perforate can be square hole, circular hole, ellipse.
The temporary fastening device that the utility model provides, also has such feature: wherein, and thru-bolt can according to the distance free-extension between upper buoyancy tank and lower buoyancy tank.
Utility model effect
Temporary fastening device involved by the utility model, have employed the combination of traditional welding and mechanical mechanism connection mode, has higher technology maturity, cost is low; 2, only need remove the connection of thru-bolt side and platform at sea when the utility model is constructed, under-water operation is few, and operation is all outside buoyancy aid, and safety is high; 3, the utility model achieves the object be connected by upper and lower buoyancy tank by simple mechanism, and in towage process, between upper and lower buoyancy tank, relative motion obtains and suppresses constraint, ensure that transportation safety.4, the utility model Applicable scope is not by the restriction of the factors such as buoyancy tank shape, size, quantity, applied widely.In sum, the utility model has and can be adapted to different scale and be connected with the buoyancy tank of shape, structural safety reliability is high, cost is low, the advantages such as offshore construction is easy, can be widely used in comprising the platform pattern of temporary fixed many buoyancy aids in the needs towage at sea of novel semisubmersible oil production platform.
