Description
Technical field
The present invention relates to a kind of structure and mounting method thereof of offshore boosting station, mainly be applicable to the ocean engineering fields such as Oversea wind power generation.
Background technology
In China, Oversea wind power generation is an emerging industry, and after 2007, China starts progressively to develop the Oversea wind power generation industry.China's Oversea wind power generation industry still belongs to the starting stage, and domestic built marine wind electric field is that the wind-driven generator electricity can be delivered to land at present, after being boosted by land booster stations, sends into electrical network.Development along with China's Offshore Wind Power Generation Technology, marine wind electric field offshore distance is more and more far away, the wind energy turbine set scale is increasing, traditional mode that land booster stations are set by land is no longer suitable because low voltage power transmission line loss copper material consumption large, cable is large, expense is high, deliver to reliably, economically inland for the electric energy safe that marine wind electric field is produced, just offshore boosting station must be set at sea.Offshore boosting station can boost to 110kV, 220kV or higher by the wind-driven generator electricity exactly, then by high-voltage undersea cable, delivers to land, then sends into the inland electrical network through high voltage overhead lines.
Offshore boosting station is arranged on marine site, can't as land booster stations, successively build, equipment is installed one by one, therefore offshore boosting station generally need adopt large-scale floating-crane ship to install, offshore boosting station is after harbour has been built, load onto barge by the large-scale crane ship integral lifting, after being transported to erecting bed by barge, by large-scale crane ship, from barge, lifted by crane again, be installed on basis, because offshore boosting station overall structure size is large, weight is large, need the large-scale crane ship that adopts the 2000t level above, and domestic large-scale floating-crane ship limited amount, expense is very high, therefore this mounting means is poor to sea situation compliance, mounting cost is high, have a big risk.For Cost reduction, offshore boosting station has further capacity increasing trend, and the overall weight of offshore boosting station also further increases, and when weight reaches a ground degree, domestic offshore crane just can not meet its lifting.Along with carrying out on a large scale of China's offshore wind farm construction, offshore boosting station is a large amount of construction, seek a kind of safe, efficient, expense is low, to the low mounting means of ship machine equipment requirement, be very urgent.
Summary of the invention
The technical problem to be solved in the present invention is: for the problem of above-mentioned existence, a kind of safe and efficient, cost saving is provided, the ship machine equipment is required to low autonomous installing type offshore booster station structure and mounting method thereof.
Another problem that the present invention will solve is: in installation process, without using large-scale crane ship, the height with the minimizing large-scale crane ship to sea situation relies on, the problem that operation is carried out in the marine site that the existing medium-and-large-sized crane ship of mounting means of solution can't be more shallow in the depth of water.
The technical solution adopted in the present invention is: autonomous installing type offshore booster station structure, comprise at least four vertical and regular arrangement piling bar, be fixedly installed in the jacket of piling bar top, and be installed on the booster stations top equipment chunk on jacket, wherein the piling bar lower end is goed deep in the following bearing stratum of sea bed, and it is characterized in that: described jacket top is provided with the hoisting mechanism for described top equipment chunk is sling; Described top equipment chunk is encircled into annular by grouping block I and the splicing of grouping block II, and the coaxial sheathed jacket periphery of being fixed in.
In described grouping block II, be provided with for regulating the adjusting setting-out cabin of its elevation.
Connect into integral body by bolt or welding manner between described grouping block I and grouping block II.
Bottom and the surrounding water-proof sealing of described top equipment chunk, surrounding is provided with the waterproof window, and is evenly arranged one group of lifting lug used for hoisting on top.
Be furnished with electric, fire-extinguishing and lifesaving and heating and ventilating equipment in the equipment chunk of described top.
Described hoisting mechanism is one group of hoist engine or the tractor system be arranged between jacket head tree and column on crossbeam.
The mounting method of offshore booster station structure is characterized in that step is as follows:
A, the processing that completes on land grouping block I, grouping block II and jacket and rigging up and debugging, then utilize barge or towboat that jacket is transported to precalculated position, the sinking jacket;
B, utilize barge or towboat that piling bar is transported to the jacket place, adopt pile driving barge that piling bar is squeezed in sea bed along the pipe casing of jacket, and utilize grouting or welding that the pipe casing of piling bar and jacket is connected as a single entity;
C, utilize towboat that grouping block I and grouping block II are hauled to the jacket place, make grouping block I pincers be located at the jacket periphery, and temporary fixed;
D, the grouping block II is drawn to opening part corresponding to grouping block I, and by bolt or welding manner, both are connected into to annular monolithic top equipment chunk, and be sheathed on the jacket periphery;
E, remove temporary fixed between grouping block I and jacket, and utilize hoisting mechanism that top equipment chunk integral body is winched to desired location, and be installed on jacket by bolt or welding manner.
In described steps d, when there are difference in height in grouping block I and grouping block II, adjust the water retention capacity in grouping block II internal regulation setting-out cabin, make grouping block I and grouping block II be positioned at sustained height, then carry out both connections.
The invention has the beneficial effects as follows: 1, the jacket top is provided with hoisting mechanism, offshore boosting station top equipment chunk can be sling, saved compared to prior art that large-scale sea is hung and relevant auxiliary ship, reduced requirement and the hoisting cost to the ship machine equipment on the one hand, also reduced on the other hand in the prior art because of the long probability that risk occurs of Potential Working Time For Operation At Sea.2, owing to not needing to adopt large-scale crane ship in installation process, avoided the height dependence of large-scale crane ship to sea situation, than the neritic zone booster stations, an inconvenient difficult problem is installed thereby solved the depth of water.3, adopt offshore platform jacket frame foundation structure pattern commonly used, the conduit soil rigidity that relatively floating holder method is installed is larger, without the jacket both sides are processed, thereby has reduced engineering quantity, has reduced the cost on jacket basis.4, jacket, grouping block process on land and rigging up and debugging after, the buoyancy that utilizes self to produce, hauled to preposition and installed and get final product by towboat, saved compared to prior art the use of large vessel, reduced cost of transportation.5, after end of run, can independently remove, transport by towboat, in order to recycle, economic environmental protection.
