Embodiment Construction
[0024] The present invention will be further described below with reference to the accompanying drawings.
[0025] see figure 1 , the overall construction method of the super large-scale upper-construction general section of the present invention comprises the following steps:
[0026] Step S1, the stage of segment division: according to the weight, volume and construction factors of the upper construction section, the upper construction section is divided into a plurality of sections for manufacture. Among them, the construction factors include: the total assembly capacity and transportation capacity of the offshore construction site, as well as the construction requirements for segmented manufacturing, turning over, painting and carrying. The superstructure can meet the basic construction and transportation requirements.
[0027] Step S2, the transportation and shelving stage: the specially designed shelving and transportation pallets are used as the intermediate medium. D...

The invention discloses an overall construction method of an ultra-large superstructure block, which comprises: a section division stage: dividing the superstructure block into a plurality of sectionsfor manufacturing according to the weight, volume and construction factors of the superstructure block; a transportation shelving stage in which shelving transportation trays are adopted as an intermediate medium, and during construction, the shelving transportation trays can be used for shelving blocks or groups; a transferring stage of jacking up the shelving transportation trays by a power module and then transferring the trays to a wharf from a platform; a hoisting stage of hoisting the superstructure block by using a hoisting structure in a hanging row mode. The overall construction of the ultra-large superstructure block can be integrated, and the outfitting integrity is improved.
Description
technical field [0001] The invention relates to the field of ship construction, in particular to the field of construction of a general section of Shanghai Construction. Background technique [0002] The full name of Shanghai Construction is the superstructure, which is used for crew or passenger accommodation and ship operation control. Its structural characteristics are that the structure is light and thin, the strength is weak, and the internal outfitting and interior decoration systems are complex. For example, if the layers are installed on the ship separately, the damage to the hoisting structure alone is too much, and the outfitting and installation stage is moved backward, which affects the installation dock. internal efficiency. The overall size and tonnage of the super-large superstructure of FPSO have reached a record high, with a weight of 1,800 tons, and the internal structure outfitting is more complicated than that of conventional ships, so the overall constr...
