The invention provides a light marine bulwark door, and relates to the technical field of ocean
engineering, the marine bulwark door is adaptively mounted on an obliquely arranged bulwark and comprises double bulwark
doors, each bulwark door is hinged to the bulwark, each bulwark door comprises an obliquely arranged door plate, and the top end and the bottom end of each door plate are arranged in a state of obliquely extending towards the outside of a ship; a flanged plate is fixedly arranged on the side edge, close to the bulwark, of each door plate, and the flanged plates are hinged to the adjacent bulwark. The bulwark door is easy to manufacture and convenient to operate, the flanged plates are arranged on the side edges of the door plates, the flanged plates are hinged to the connecting plates fixedly welded to the bulwark, meanwhile, the inclination angle of the bulwark door and the inclination angle of the bulwark are kept consistent, when the bulwark door is horizontally opened, opening and closing of the bulwark door are kept at the same height all the time, and the bulwark door is not prone to falling off. The bulwark door and the bulwark are more harmonious and attractive in connection, and equipment throwing is more convenient.
