Oceanography engineering module integral hoisting method

The invention discloses a method used for realizing the integral lifting of marine engineering modules in the marine engineering field. After the module is constructed integrally, the invention makes use of floating cranes, barges and special crane beams to realize the integral lifting of modules on water by regulating the sea gauge of a main hull. Compared with the similar technology, the invention has the following advantages that the preparation of special crane beams can reduce the length of lifting cables so as to enhance the effective lifting height of floating cranes; and the adopting of the floating crane to lift the modules to the barges can avoid the use of a plurality of fittings used for conveying so as to reduce the cost. Simultaneously, the deep water is adopted to moor the main ship so as to ballast the main hull and reduce the height of the freeboard and then the high lifting capability of the floating crane is enhanced and the shipbuilding cost is reduced finally.
