The cables in the above embodiment are laid after all the grid sections are assembled on the hull, so as to ensure the integrity of the cables. In one embodiment, cables may be installed in each partition, specifically, partition cables are prepared based on cable paths and cable lengths between cable starting points and cable ending points of the grid partitions, the number and positions of cable brackets on the cable paths of the grid partitions are obtained according to drawing data of a grid area, the cable brackets are arranged on the grid structure along the cable paths, the partition cables are installed on the cable brackets along the cable paths, and finally, after the grid partition hull is assembled, the partition cables between the grid partitions are spliced at the cable starting points and the cable ending points. It should be noted that, because the cables are distributed to each grid partition, the splicing part needs to be provided with a plug which meets the quality and safety standards, so as to ensure the stability of the transmission of electricity and electric signals.
In one embodiment, identifying a cable start point and a cable end point in each grid sector comprises the steps of: and marking the boundary point of the cable of each grid subarea and the cable of the previous grid subarea as the starting point of the cable of the grid subarea, and marking the boundary point of the cable of each grid subarea and the cable of the next grid subarea as the terminal point of the cable of the grid subarea.

the grid section and the piping connection of the preceding grid section are identified as piping starting points, and the grid section and the piping connection of the following grid section are identified as piping terminal points.
Since the pipe is typically a standard part, it may be on the body of the pipe at the dashed line boundary in fig. 2, where it is broken off, and a separate treatment of the joint is required, increasing the amount of work. Therefore, the pipe system is cut off at the joint of the pipe system at the boundary of the grid partition, the integrity of the pipe system standard part can be ensured, and when the subsequent grid partition is assembled, the pipe system can be spliced only by connecting the joint standard part without welding and other operations. If no pipe system structure exists at the boundary of the grating subarea or the distance of the pipe system joints is too far, the pipe system needs to be cut off at the moment so as to prevent the pipe system from being too long, increase the overall weight of the grating subarea and increase the risk in hoisting.
In one embodiment, the step of dividing the grid area into a plurality of grid zones comprises the steps of:
s11, dividing a grid area into a plurality of primary partitions according to the condition that M is less than or equal to M;
s12, searching a keel closest to the grid structure at the boundary of the primary partition, and adding a boundary at the keel;
s13, dividing the grid area into a plurality of preliminary subareas again along the boundary, and setting the weight of the preliminary subareas as t2 and the occupied space of the preliminary subareas as m2;
s14, judging the size relationship between T2 and T, and simultaneously judging the size relationship between M2 and M; if T2 of all the preparation subareas is less than or equal to T and M2 is less than or equal to M, the preparation subareas are the final grid subareas; if there is a spare partition that does not satisfy T2 ≦ T and M2 ≦ M, then steps S11 through S14 are repeated.
The steps can ensure that the obtained grating structure of the grating subarea is stable, and the weight and the volume of the final grating subarea can not exceed the hoisting limit weight and the hoisting limit space.
