Floating dock underwater assembly technology

Abstract

The invention relates to a floating dock underwater assembly technology. The floating dock underwater assembly technology is characterized by comprising the following specific technological steps of S1, ship segment, S2, launching, S3, self-loading control, S4, loading and ship moving, S5, total segment underwater assembly accuracy control, and S6, total segment underwater assembly. According to the floating dock underwater assembly technology, a whole ship is constructed independently, simultaneous construction can be conducted on different sites, and thus the construction period is shortened; as long as the dock conditions are adequate, construction is conducted by assembling together, and thus work after launching can be reduced; and a middle segment loads bow and stern segments, thus the demands for dock length conditions can be reduced, through loading construction, the dock utilization rate can be effectively increased, balance input of labor is facilitated, production plans arearranged flexibly and reasonably, the labor working environment can also be greatly improved, the way of entering a cabin of all major equipment is simplified, and the floating dock underwater assembly technology is of great significance to increasing of productivity of a shipyard.

Description

technical field [0001] The invention relates to the technical field of marine engineering ship construction, in particular to an underwater closing process of a floating dock. Background technique [0002] In shipbuilding, the shipbuilding cycle and dock capacity are important manifestations of a shipyard's construction capabilities, and are also important indicators for measuring and delivering ships and realizing economic benefits. [0003] On the one hand, the most direct way to shorten the ship construction cycle is to shorten the berth or dock cycle. Modern large-scale shipyards generally adopt dock assembly, and improving the utilization rate of docks, that is, increasing the number of docks is the first to bear the brunt of the bottleneck that shipyards need to break through. Modern large-scale shipyards generally face the problem of many types of ships and short construction periods. The entire ship can be built separately at different sites such as slipways and doc...

Problems solved by technology

[0004] On the other hand, for floating docks, especially large floating docks capable of repairing ships with large deck load areas, the length and width of dry docks have become the main constraints on the construction capacity of floating docks. fold and launch
