Embodiment Construction

[0011] Take the simultaneous construction of four CS4250 container ships in the same dock as an example. As shown in Fig. 1, the present invention is used in the simultaneous construction method of four ships in the dock during the ship building process. The construction method of shipbuilding in the dock of the present invention is to build two stern and a half ships 1 at the free position behind the longitudinal rear of the two parallel whole ships (can be called the rear position of the dock) while building two whole ships 2 in a dock. When the ships of two of the whole ships are built and need to go out of the dock to float and move, the dock door 3 is opened to allow the sea water outside the dock to flow naturally into the dock, so that the ships of the two whole ships can float and move out of the dock. The other two stern half-ships are under construction, so these two stern half-ships are loaded so that their weight is greater than the buoyancy, so that the stern half...

Abstract

The invention discloses a method that other ships are also built in unoccupied places while a ship is built in a shipyard. When one of ships is required for undocking or floating to move positions, a dock gate is opened to cause seawater outside the shipyard to flow into the shipyard naturally, thus the ships required for movement are caused to float and move while other ships being built in the same shipyard are loaded and maintained on pier sites for keeping on installation and building. Therefore, not only can the cost be reduced and the building precision of the ships being built be easily controlled, but also resources in the shipyard can be effectively utilized for improving the functions of use in the shipyard and shortening the building period in the shipyard. Furthermore, the shell body and superstructure of the ship, dead weight of equipment and a certain amount of ballast water can be fully utilized for forming the load.

Description

technical field [0001] The present invention is a kind of construction method that builds a plurality of ships simultaneously in the dock. Specifically, it is a construction process in which multiple ships are simultaneously built in the dock, and when the built ships need to float and move, keep other ships from floating and operate normally. Background technique [0002] In the shipbuilding industry, in order to expand the volume ratio of the dock, the "one and a half" construction method is usually adopted: according to the total length of the large dock, a whole ship and a half ship are built in series. After the whole ship is out of the dock, another half ship Float, drift to the full ship build position to build the full ship. The hull is divided into several sections and constructed separately, and then the entire hull is constructed by positioning and combining the sections. [0003] With the existing construction technology in the dock, if many ships are built at ...
