[0038] like Figures 1 to 6 As shown, in one embodiment, the present invention provides a fixed ballast structure, which includes a plurality of bricks;

[0039] A plurality of bricks 1 are laid on the inner bottom 100 of the hull, and the bricks 1 are fixed by pouring.

[0040] This embodiment provides a specific implementation of a fixed ballast structure. In existing technologies, ballast water can provide stability to the entire hull during navigation. However, with the continuous emergence of new ship types, in order to better adjust the center of gravity of the entire ship, ballast water, due to its relatively fixed density and light weight, cannot meet the new requirements of existing designs. Therefore, we use bricks to replace ballast water and lay them on the bottom of the ship's inner cabin. Since the density of the bricks can be controlled, the overall center of gravity of the hull can be controlled, which helps to solve the technical problem of low ballast water filling density and difficult to calculate the center of gravity in existing technologies.

[0041] The pouring here can be done with iron-tin liquid.

[0042] In one embodiment, the brick body 1 includes a first type of brick body and a second type of brick body. The first type of brick body has a size of 150 mm long, 15 mm wide, and 150 mm high, and a density of 3.0 t / m 3 The second type of brick has a size of 150mm*150mm*50mm and a density of 3.0t / m 3 .

[0043] In this embodiment, a specific size implementation of the brick body is provided, and the brick body can be made of tin iron.

[0044] In one embodiment, the bricks 1 are laid along both sides of the center line in the longitudinal direction of the hull.

[0045] In this embodiment, a specific implementation method for laying the bricks is provided.

[0046] In one embodiment, the brick body 1 is laid on the bottom of the ship in two parts, with a non-fixed ballast area passing through the middle.

[0047] This embodiment provides a specific implementation method of paving on both sides.

[0048] In one embodiment, the two parts are laid out in an asymmetrical layout.

[0049] In this embodiment, a specific implementation method of laying two parts with an asymmetric layout is provided. The offset position of the center of gravity along the center line can be calculated according to the equipment and other structures of the hull, and the overall center of gravity can be adjusted using the asymmetric layout.

[0050] In one embodiment, robots may be used to automatically lay the bricks.

[0051] In this embodiment, a specific implementation method in paving work is provided. Since brick construction is adopted, it can be realized in an automated manner.

[0052] In one embodiment, a keel rib gap 101 is reserved after the brick body 1 is cast, and the interior space of the hull has a keel rib 11 , which is stuck in the keel rib gap 101 .

[0053] In this embodiment, a specific implementation method of positioning by keel reinforcement 11 is provided. In order to prevent the entire brick body 1 from sliding or problems in pouring, positioning is performed by keel reinforcement 11. Figure 3 As shown, the keel ribs 11 are arranged at intervals, and keel rib gaps 101 are reserved when the brick bodies 1 are arranged. The keel ribs 11 are placed therein. The keel ribs 11 on the left side can be directly stacked and placed. A step is provided at the bottom, and the keel ribs 11 lean against the step. The step will level the upper end surface to facilitate the placement of the brick body 1, and the side end surface of the step 1 will abut the keel rib 11.

[0054] In one embodiment, the second type of bricks are used to fill gaps.

[0055] In this embodiment, a specific application scenario implementation of different types of bricks is provided, and the second type of bricks can be laid according to different laying requirements.

[0056] In one embodiment, gridded partitions are laid, and the bricks are laid in the areas.

[0057] In this embodiment, a specific implementation method for laying grid partitions is provided.

[0058] In order to further divide the interior cabin area, frames are then set up in different areas, keel reinforcements are set on the frames, and finally bricks are laid to improve the safety of the overall structure.

[0059] In one embodiment, the present invention further provides a ship having a fixed ballast structure, wherein the ship has the fixed ballast structure.

[0060] In this embodiment, a specific implementation of a ship with a fixed ballast structure is provided.

[0061] Beneficial effects:

[0062] Compared with existing fixed ballasts, this fixed ballast is innovative in that it has a fixed shape, a relatively high density, and a filler material to fill the gaps, making it easy to fix. The high density, heavy weight, and shape of this fixed ballast make it easy to calculate the center of gravity and better ensure the stability of the ship.

[0063] The HL ine 8600 dual-fuel PCTC vessel has used this fixed ballast and has been approved by the shipowner and ship inspector.

[0064] The fixed ballast has high density, heavy weight and good shape, which is convenient for calculating the weight center of gravity and better ensuring the stability of the ship. The innovative fixed ballast density design can improve the competitiveness of Guangzhou Shipyard in the market and enhance the reputation of Guangzhou Shipyard's ship design technology in the market.
