A shore test method for ship side lights

Abstract

The invention discloses a method for testing side lamps of ships on shores. The method particularly includes steps of mounting the side lamps in side lamp boxes on the shores; detecting the mounting precision of the side lamps; transporting the side lamp boxes to specified locations on the ships by cranes; adjusting the locations of the side lamp boxes to allow the longitudinal center lines of theside lamp boxes to be parallel to the center lines of hulls; fixedly welding the side lamp boxes with the hulls. The method has the advantages that the method is simple and speedy and is high in reliability; the side lamps are mounted in the side lamp boxes on the shores, the mounting precision of the side lamps is detected, the side lamp boxes are transported onto the ships by the cranes after the precision of the side lamps is detected, accordingly, the problem of incapability of directly checking out the mounting precision of the side lamps on the ships can be effectively solved, the tugboat expense in later periods can be saved, the mooring test time can be saved, and the shipbuilding efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of ship building, in particular to a shore test method for ship side lights. Background technique [0002] The side light is a necessary sound and light signal equipment when the ship is sailing. With the development trend of ships becoming larger, multi-purpose, and load-maximizing, the arrangement of sidelights is also facing more and more difficulties. The side lights include a green light on the starboard side and a red light on the port side, each displaying uninterrupted lights within a horizontal arc of 112.5°, and the devices are to display the lights from the front of the ship to within 22.5° behind the beam of each side. The side light box is used as a storage and protection device for the side light, and whether its form and position are appropriate plays a decisive role in whether the side light can function. If the side lights are blocked, it will convey wrong navigation information, so that t...

AI Technical Summary

Problems solved by technology

If the side light is blocked, it will convey wrong navigation information, so that the crew cannot correctly judge the navigation status of the other ship, resulting in navigation accidents

[0003] The installation and inspection of side lights are involved in the ship construction process. Due to the different installation positions of ship side lights, when testing the installation accuracy of side lights near the bow, the installation accuracy cannot be directly tested according to the "1972 International Regulations for Preventing Collisions at Sea"
