Abstract
Description
Technical Field
[0001] This invention belongs to the field of marine vessel design and construction, and specifically relates to a marine modular foremast. Background Technology
[0002] When deck space in the bow area of a ship is limited, such as in the design of container ships, to maximize the loading of more containers—for example, if the shipowner wants to load longer 45-foot containers in an area that originally accommodated 40-foot containers—the overall design length is fixed. Increasing the length not only increases the ship's weight but also involves a series of issues related to the ship's overall strength and stability. In such cases, the usual solution is to not modify the length. In order to lengthen the cargo hold area during the design phase, the space on the bow and stern decks inevitably has to be reduced.
[0003] Therefore, a design is needed that combines the foremast and bow wave deflector, eliminating the deck space occupied by the original independent foremast. This is especially beneficial when the bow space needs to be shortened. This new combined foremast avoids the problem of insufficient space for the arrangement of bow moorings, anchor winches, and bollards, thus effectively utilizing the bow space. Summary of the Invention
[0004] To solve the above problems, the present invention provides a marine composite foremast, the technical solution of which is as follows:
[0005] A marine composite foremast is provided with a wave deflector installed on the bow deck of the hull, with both ends of the wave deflector extending to the sides of the hull. The foremast is fixed at the center of the wave deflector and has an upright mast body. The mast body and the wave deflector are an integral structure.
[0006] The mast is equipped with a lower platform and an upper platform. The lower platform is located above the wave deflector and below the upper platform, while the upper platform is located at the top of the mast. A straight ladder is provided between the lower and upper platforms. The lower platform is equipped with radar and lighting, while the upper platform is equipped with an electric horn, navigation light pole, and lighting.
[0007] The mast is symmetrically equipped with stabilizing cables on both sides. One end of the stabilizing cable is fixed to the upper platform, and the other end is fixed to the wave deflector. The stabilizing cable and the wave deflector form an acute angle. A bell and a manhole cover are installed at the bottom of the mast.
[0008] Furthermore, the aforementioned marine composite foremast has a mast height of 25 meters and a wave deflector height of 9 meters.
[0009] Furthermore, the aforementioned marine composite foremast is equipped with a foremast light and an anchor light on the navigation light post.
[0010] Furthermore, the aforementioned marine composite foremast is further equipped with railings around both the upper and lower platforms.
[0011] Furthermore, in the aforementioned marine composite foremast, a reinforcing elbow is provided at the connection between the top of the wave deflector and the mast body.
[0012] Furthermore, the aforementioned marine modular foremast is equipped with a ladder inside the mast body, which extends from bottom to top to the upper platform.
[0013] This integrated foremast and wave deflector structure effectively reduces vibration and tremor issues caused by the height (typically around 25 meters) of the original independent foremast. By eliminating the deck space occupied by the original independent foremast, it effectively utilizes the bow space. This modular foremast design solves the problem of insufficient space for the arrangement of bow anchoring systems, mooring winches, and bollards. Attached Figure Description

[0017] A marine composite foremast includes a wave-breaking plate installed on the bow deck, extending to the sides at both ends. A foremast is fixed to the center of the wave-breaking plate, and the foremast has an upright mast body. The mast body and wave-breaking plate are an integral structure. A reinforcing elbow plate is installed at the connection between the top of the wave-breaking plate and the mast body. The mast body is 25 meters high, and the wave-breaking plate is 9 meters high.
[0018] The mast is equipped with a lower platform and an upper platform. The lower platform is located above the wave deflector and below the upper platform, while the upper platform is located at the top of the mast. A straight ladder connects the lower and upper platforms. The lower platform is equipped with radar and lighting, while the upper platform is equipped with a horn, navigation light post, and lighting. The navigation light post is equipped with a foremast light and anchor light. Both the upper and lower platforms are surrounded by railings to protect personnel operating and maintaining the equipment.
[0019] Symmetrical stabilizing cables are installed on both sides of the mast, with one end fixed to the upper platform and the other end fixed to the wave deflector, forming an acute angle with the wave deflector. The main purpose of the cables is to prevent the upper platform of the foremast from shaking due to strong winds, thus stabilizing the mast. Hull bulwarks are installed on both port and starboard sides of the ship, and are welded and fixed to both sides of the wave deflector to form a whole, which greatly benefits the overall strength of the wave deflector.
[0020] The mast is equipped with a horn and a manhole cover at the bottom. Inside the mast, there is a ladder that extends from bottom to top to the upper platform. Personnel can enter the straight ladder passage inside the foremast through the manhole cover and reach the lower and upper platforms to operate and maintain the relevant equipment.
[0021] The device of this invention is optimized in design, safe and reliable, easy to operate, and meets the relevant specifications.
[0022] This invention, by combining the foremast and bow wave deflector, frees up deck space previously occupied by a separate foremast, particularly useful when bow space needs to be reduced. This modular foremast design avoids the problem of insufficient space for bow mooring, anchor winches, and bollards, thus effectively utilizing bow space. Furthermore, because it is integrated with the wave deflector, this structure effectively reduces vibration and tremor caused by the foremast's height.
