The object of the invention is to be realized by following technical scheme:
A mounting method for ocean platform module passive type traction enhancement, is characterized in that: adopt following installation steps:
The first step: upper chunk is fixed on barge, then, completes floating holder barge and enter ship, and enter in the notch of jacket;
Second step: insert the position of point and outer four shanks of jacket according to the shank of upper chunk, use anchoring system to adjust the position of barge, and the calibration of completing place;
The 3rd step: barge is carried out to ballast, by controlling barge motion, keep the shank of upper chunk to insert point and the outer four leg docking catching ranges of jacket;
The 4th step: the shank that completes upper chunk is inserted point and is located at after the buffer docking of the outer four leg shanks of jacket, then barge is carried out to ballast; When upper chunk and barge transport disengaging height reach while moving back ship requirement, move back ship;
The 5th step: promote upper chunk to setting height, then, regulate the traction enhancement device that is located at outer four shanks of upper chunk, the support reaction of outer four shanks of distribution ducts frame; Finally, upper chunk is connected at four leg places outside with jacket, and discharges the weight of upper chunk;
The 6th step: utilize traction downward putting device to transfer interior four legs of jacket, and complete docking of interior four legs and jacket shank, meanwhile, complete the distribution of weight of upper chunk on interior four legs;
The 7th step: upper chunk is connected with interior four legs of jacket, and discharges the weight that is located at the traction downward putting device upper chunk on interior four legs.So far, the floating holder traction of whole chunk installs.
In the described first step: it is to complete by anchoring system, the lifting of entering ship cross lines and tidal level that floating holder barge enters ship.
In described second step: adjust the position of barge, and the calibration of completing place is to use anchoring system to carry out.
In described the 5th step: promoting upper chunk to setting height is to utilize traction enhancement device to carry out.
Beneficial effect of the present invention: the present invention is owing to adopting technique scheme, and it not only can reduce the height of upper chunk on barge, obtains better stability; And, reduce installation shock load, reduce environmental requirement, expand the window of selecting barge, be conducive to marine duration selection of installing; Meanwhile, under static environment condition, promote chunk, can increase significantly the marine safety and reliability of installing.
