Description

Technical Field

[0001] The invention relates to the field of shipbuilding, and in particular to a method for constructing a bow thruster in sections. Background Art

[0002] As an important part of the ship operating system, the bow thruster has been widely used on ships. Due to the structural form, the bow thruster often needs to be installed in advance in the segmented stage, and the installation accuracy of the bow thruster is very high.

[0003] The conventional construction method of the bow thruster section is to install the bow thruster and other outfitting parts after the section structure is formed, but this construction method has great limitations. First, it is difficult to adjust the accuracy of the bow thruster after the structure is complete, and it is easy to bump into it during the lifting process. Second, it is necessary to wait until the bow thruster is installed before installing the iron outfitting platform, piping, electrical equipment and many other outfitting parts, which seriously affects the construction efficiency. In addition, the iron outfitting platform needs to be installed normally inside the section, which makes the construction difficult. Summary of the invention
