Method for opening porthole of ship and ship

Abstract

The invention discloses a ship porthole opening method and a ship, wherein, after the hull is largely closed, the superstructure is integrally welded to the hull and the pyrotechnic operation is completed, each window hole of the superstructure is marked on the side outer plate respectively. The lower edge line, upper edge line, front edge line and rear edge line, and keep the lower edge lines corresponding to the windows on the same side and the same layer are distributed on the same horizontal line, keep the same side and the same layer The upper edge lines corresponding to each of the window holes are distributed on the same horizontal line, and the front edge lines and the rear edge lines are kept vertically distributed. The opening method of the porthole can meet the precision and aesthetic requirements of opening the window hole.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a method for opening ship portholes and a ship. Background technique [0002] Generally, ships need to have portholes on the straight outer panels on the left and right sides of the superstructure. There are two traditional opening methods for ship portholes. 1. CNC cutting the window holes in the stage of small closing and blanking. This method is difficult to ensure that the portholes on each floor are at the same height, and the aesthetics of the ship is poor; 2. In the In the general assembly stage, the window openings are drawn uniformly first, and then the sub-sections or the overall section are hoisted into the dock for large-scale closing of the hull. The impact of positioning data and structural docking of sections or total sections, as well as the deformation of the hull during welding and pyrotechnic operations, may cause the upper or lower edges of the front and rear w...

The impact of positioning data and structural docking of sections or total sections, as well as the deformation of the hull during welding and pyrotechnic operations, may cause the upper or lower edges of the front and rear windows to not be at the same height, resulting in the overall window hole If the accuracy and aesthetics cannot meet the requirements, it may be necessary to partially trim the window hole or even change the board to re-cut the window hole, which will increase the cost of opening the porthole
