Description

Technical Field

[0001] The invention relates to the technical field of multi-purpose ship design, and in particular to an ammonia fuel reservation arrangement structure of a multi-purpose ship. Background Art

[0002] A multipurpose ship is a ship that has multiple functions. In a broad sense, any ship that can carry more than two types of cargo can be called a multipurpose ship. However, the multipurpose ships generally referred to refer specifically to multipurpose dry cargo ships. There are many types of dry cargo, which can be classified into five categories according to their requirements for ship performance and equipment, namely general cargo, bulk cargo, container, heavy cargo and ro-ro cargo. The goal of a multipurpose ship is to be able to carry more types of cargo more efficiently.

[0003] Ammonia fuel is easy to store, and only produces two chemical substances, nitrogen and water vapor, after combustion, and no harmful substances. Therefore, choosing ammonia fuel instead of traditional fossil fuels as ship fuel can greatly reduce the impact on the environment. However, ammonia fuel has a low energy density and needs to occupy more fuel tank volume. In addition, ammonia fuel is toxic, so a reasonable layout structure is needed to improve the space utilization of the ship.

[0004] Existing multi-purpose ships often use a single heavy oil as ship fuel and install ship desulfurization equipment to improve the pollution of exhaust emissions to the environment. Since the desulfurization equipment is large in size and expensive, it not only occupies a large amount of engine room shed space, but also has a high construction cost. Summary of the invention

[0005] The technical problems to be solved by the technical solution of the present invention are: 1. Heavy oil fuel has a great impact on the environment; 2. Burning heavy oil requires a ship desulfurization device, which is expensive; 3. The ship desulfurization device is large in size and occupies a large amount of engine room shed space.

[0006] In order to solve the above technical problems, the technical solution of the present invention provides an ammonia fuel reserved arrangement structure for a multi-purpose ship, in which the highest open deck on the hull is used as the main deck, the deck one layer above the main deck is used as the A deck, the structure with spaces on both sides above the main deck is defined as the superstructure, and the structures on both sides of the uppermost part of the superstructure are defined as the wheelhouse wing bridge;

[0007] The ammonia fuel reservation arrangement structure comprises:

[0008] If it is at the ammonia fuel tank reservation stage, the containers are placed on the A deck and located on both sides of the superstructure and under the bridge of the bridge;

[0009] If the saddle reinforcement structure and the ammonia fuel tank are being installed, the container is removed and replaced with a saddle reinforcement structure located on deck A and on both sides of the superstructure, and an ammonia fuel tank located above the saddle reinforcement structure.

[0010] Preferably, the front end of the container is located behind the front bulkhead of the superstructure.

[0011] Preferably, the container is in an open air environment to facilitate loading and unloading of the container.

[0012] Preferably, the saddle reinforcement structure also includes a supporting bracket, which faces the center of the ammonia fuel tank in the cross-section.

[0013] Preferably, the supporting elbow plate is a folding elbow plate and a T-shaped panel.

[0014] Preferably, the saddle reinforcement structure also includes a web and a transverse bulkhead supporting the web, a plurality of panels are arranged around the web, and wooden blocks are placed above the panels to support the ammonia fuel tank.

[0015] Preferably, the multipurpose vessel further comprises a lifeboat located in the middle of the vessel near the stern, and the ammonia fuel tank is located in front of the lifeboat.

[0016] Preferably, the multipurpose vessel further comprises a chimney located above the superstructure, and the distance between the ammonia fuel tank and the chimney is more than 5 meters.

[0017] Preferably, the ammonia fuel reserve arrangement structure further comprises a mooring winch and a large number of mooring parts located between the main deck and the ammonia fuel tank.

[0018] Preferably, the hull outer plate of the multipurpose vessel extends upward and is welded to the saddle reinforcement structure to form an integral structure.

[0019] The technical solution of the present invention proposes a multi-purpose ship's ammonia fuel reserved layout structure, which arranges the ammonia fuel tank on the A deck one layer above the main deck, making full use of the space on both sides of the superstructure and under the wing bridge, perfectly avoiding the mooring winch and a large number of mooring parts on the main deck, and more rooms can be set up on the main deck. The ammonia fuel tank in the technical solution of the present invention is reasonably arranged, the fireproof space is sufficient, the deck passage meets the regulatory requirements, and the personnel cabin meets the safety requirements, which can provide structural safety protection for the shipowner to add and modify the ammonia fuel tank in the later stage. In addition, during the operation cycle of the ship without the installation of the ammonia fuel tank, containers or other dry goods can be placed on the A deck to meet the shipowner's more loading needs.
