Problems solved by technology

This opening method delays the time for opening the window holes, resulting in the portholes not being installed as soon as possible, delaying the construction period of the entire hull and increasing the time cost
Moreover, the efficiency of on-site drilling is low, and the quality of the drilling is poor, resulting in the accuracy and aesthetics of the overall window hole not meeting the requirements. Secondary use increases costs

Abstract

The invention relates to the technical field of ships, and discloses a ship porthole forming method, a porthole and a ro-ro passenger ship. The ship porthole forming method comprises the following steps: S1, the theoretical outer contour of porthole holes of a porthole is designed on a broadside outer plate of a ship segment; S2, the forming positions of pre-formed holes are determined along the theoretical outer contour; S3, the pre-opened holes are tapped; S4, total ship block segmentation is performed; and S5, a broadside outer plate between every two adjacent pre-formed holes is cut alongthe theoretical outer contour. The tapping efficiency and the tapping quality are improved, the cost is reduced, and the construction period of a ship is shortened.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a method for opening ship portholes, portholes and a ro-ro passenger ship. Background technique [0002] Generally, portholes are provided on the straight outer panels on the left and right sides of the ship. At present, the opening method of the porthole of the ship is mainly as follows: the general section of the ship is formed by the general assembly of the ship sections, and after the general section of the ship enters the dock and completes loading, the opening outline of the porthole is marked on the side shell plate on site, and then Cut and open the window. This opening method delays the time for opening the window hole, causing the porthole to be installed as early as possible, delaying the construction period of the entire hull and increasing the time cost. Moreover, the efficiency of on-site drilling is low, and the quality of the drilling is poor, resulting in the acc...
