Floating condition manufacturing method for extra-long hull

Abstract

The invention discloses a floating condition manufacturing method for an extra-long hull. The floating condition manufacturing method comprises the following steps of (1) dividing the hull into three parts, namely a lower hull, an upper hull and a superstructure, wherein the lower hull is divided into a stern complete cross section and a bow complete cross section; (2) separately manufacturing the stern complete cross section and the bow complete cross section on two barges; (3) when the length of a built part of the stern complete cross section is the same as that of the barges, enabling the barges to submerge and translate for a certain distance towards the direction of a bow, and then enabling the barges to float upwards support the built part of the stern complete cross section, and continuing construction until the stern complete cross section is completed, wherein the constructing manner of the bow complete cross section and the construction manner of the stern complete cross section are basically consistent but have a difference that the barges are translated towards the direction of a stern instead of the bow; (4) performing closure on the stern complete cross section and the bow complete cross section; (5) enabling the two barges to submerge for removing; and (6) manufacturing the upper hull and the superstructure on the lower hull. According to the floating condition manufacturing method disclosed by the invention, constructing a special dock and a special berth is not needed, so that the construction cost can be reduced, the cycle can be shortened, the requirement for a site is low, and the adaptability is high; and the hull lunching is realized through the submerging of the barges, so that mechanical damages cannot be generated on the hull.

Description

technical field [0001] The invention relates to the technical field of marine engineering equipment, in particular to a method for manufacturing an ultra-long hull in a floating state. Background technique [0002] With the exploitation of marine resources becoming more and more abundant, the demand for resources of various countries is gradually increasing, and the trade of various countries is becoming more and more frequent. In order to save costs, the size of ships transporting at sea is becoming larger and larger. Construction requires huge docks and slipways, and the construction of these special docks and slipways requires high input costs, long construction periods, large site occupation, poor adaptability, and low utilization rate. In addition, the safe launching of super-large ships is also one of the most important processes in the construction process. Super-large ships are heavy in themselves, and the traditional launching method will not only damage the foundat...

Problems solved by technology

[0002] With the exploitation of marine resources becoming more and more abundant, the demand for resources of various countries is gradually increasing, and the trade of various countries is becoming more and more frequent. In order to save costs, the size of ships transporting at sea is becoming larger and larger. Construction requires huge docks and berths, and the investment cost of building these special docks and berths is high, the construction period is long, the site is large, and the adaptability is poor and the utilization rate is low

In addition, the safe launching of super-large ships is also one of the most important processes in the construction process. Super-large ships are heavy in themselves, and the traditional launching method will not only damage the foundation of the dock, but also cause a certain degree of mechanical damage to the hull. will have an incalculable impact on its service life
