A support method for normal installation of hatch coaming on ultra-large container ships

Abstract

The invention discloses a support method for normally installed hatch coaming of an ultra-large container ship. The support method for the normally installed hatch coaming of the ultra-large containership specifically comprises the following steps that scribing is performed on a platform to determine position lines of adjusting ground piers; first channel steel is welded on T-type total set ground piers; the adjusting ground piers and the T-type total set ground piers are placed; all the adjusting ground piers are adjusted to the same horizontal height, and the T-type total set ground piers are welded; broadside torsion box subsections are hoisted and placed on the adjusting ground piers; the broadside torsion box subsections and the first channel steel are welded and fixed; and the hatchcoaming is normally installed. According to the support method for the normally installed hatch coaming of the ultra-large container ship, the hatch coaming can be normally installed on the platform,the time of installing the hatch coaming in the docking stage can be reduced, the docking cycle is shortened, the number of turning over of hatch coaming subsections is reduced, and the reduction ofthe use time of a gantry crane is facilitated; and when the hatch coaming subsections are coated after the installation is completed, the damage to the deck paint by the bulk hatch coaming in the docking stage is avoided.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a support method for normally installing hatch coamings on ultra-large container ships. Background technique [0002] At present, the container ship is developing in the direction of large-scale (VLCS), and the section of the side torsion box is getting larger and larger, and the center of gravity is higher. There are two main types of hatch coaming installation: [0003] 1. Horizontal installation [0004] This method has the following drawbacks: [0005] First, the horizontal installation can only be welded on one side. In order to prevent welding deformation during the welding process of the hatch coaming, a large number of channel steels need to be welded on the hatch coaming and the deck. At the same time, the channel steel needs to be polished after cutting Hatch coaming and deck surface increase the workload on site. [0006] Second, the horizontal installation ne...
