Segmented construction method for bow door of ro-ro passenger ship

Abstract

The invention provides a segmented construction method for a bow door of a ro-ro passenger ship, which can reduce the construction period of the ro-ro passenger ship. The segmented construction method for the bow door of the ro-ro passenger ship comprises the following steps: S1, independently constructing a first bow part section associated with the bow door, a second bow part section associated with the bow door, a bow part section and a bow door section; s2, pre-assembling the bow section and the bow door section; and S3, performing block assembly on the pre-assembled bow section, the pre-assembled bow door section, the first bow section associated with the bow door and the second bow section associated with the bow door, wherein the bow door section can be opened relative to the bow section. According to the segmented construction method for the bow door of the ro-ro passenger ship, the construction period of the ro-ro passenger ship can be shortened.

Description

technical field [0001] The invention belongs to the technical field of shipbuilding, and in particular relates to a segmented construction method for a bow door of a ro-ro passenger ship. Background technique [0002] The ro-ro passenger ship is a passenger / vehicle ro-ro ship that mainly sails in international coastal waters and is used to carry tourists, cars, trucks and container trailers. The main function of the existing ro-ro passenger ships is to carry passengers, carry cars, trucks and container trailers. There are several vehicle compartments inside the ship, and the front and stern vehicle springboards are arranged at the front and rear ends of the vehicle compartments, and the bow and stern springboards are used to connect with the shoreline wharf, so that vehicles of different load types can enter and exit between the vehicle compartment of the ro-ro passenger ship and the wharf. Since the bow springboard is set inside the bow vehicle compartment, the bow door is...

AI Technical Summary

Problems solved by technology

[0009] 1. The overall construction period of the bow door section is long;

[0010] 2. The boundary area between the bow door hull structure and the bow door is narrow, and the construction work of hull assembly and welding is difficult;

[0011] 3. A large number of hull structures can only be constructed after the bow door is opened, and high-altitude operations occupy a large amount of production auxiliary resources such as cranes and scaffolding
