METHOD FOR MANUFACTURING AUTOMATICALLY DETACHABLE BULBOUS BOW

摘要

Disclosed is a method for manufacturing an actively separable bulbous bow, which comprises the following steps: A. material selection: selecting a high-strength material; B. material shaping: processing the high-strength material into a matched size and shape according to the size and shape of a connecting part between the bulbous bow and a main hull; C. installation: installing the above-mentioned high-strength material at the connecting part between the bulbous bow and the main hull using a welding, bonding or embedding process for connecting the bulbous bow to the main hull; D. grinding treatment: grinding the above-mentioned connecting part to ensure that there is a smooth transitional connection between the bulbous bow and the main hull; E. rust prevention: adopting sandblasting and undercoating; and F. non-destructive watertight inspection: performing the non-destructive watertight inspection on the connecting part between the bulbous bow and the main hull. The high-strength material is a low-alloy and high-strength metal, with a yield strength value of not less than 390 Mpa, and using the bulbous bow can reduce the damage to the hull of an opposite ship caused by the bulbous bow during ship collision.
