Description

Technical Field

[0001] The invention belongs to the technical field of ships, and in particular relates to a pipeless container ship cargo hold structure and a ship. Background Art

[0002] The characteristics of container ships are that the engine room is at the stern, the cargo hold is in front of the engine room, and the superstructure is at the stern of the ship. The superstructure is the main place for crew members to live and reside. The design of the cargo hold is generally divided according to the standard container length of 40 feet, so the cargo hold is divided into multiple cargo holds for loading containers. The bottom of the cargo hold is the bottom ballast tank, the side is the side ballast tank, and the top of the side ballast tank is a passage for the crew to go from the engine room to the bow and cargo hold. In addition to the bottom ballast tank, the double bottom of the cargo hold is generally designed with a pipe tunnel in the middle to arrange the ballast pipes, bilge water pipes, fuel pipes, low-sulfur oil and other pipelines of the ballast tank. At the same time, it is matched with the maintenance of pipeline valves and is equipped with a pipe tunnel trolley. This layout can better arrange the pipeline centralized system of the cargo hold area in the pipe tunnel. Passages are designed at the front and rear ends of the pipe tunnel for crew to enter and exit the pipe tunnel for maintenance. The pipe tunnel is designed as a structure, and there will be no collision with the pipeline when loading containers. Traditional container ships adopt a double-bottom design with a pipe tunnel layout, such as Figure 1 shown.

[0003] However, this layout also has related disadvantages. For example, the design of the pipe tunnel will affect the integrity of the hull structure. The arrangement of the pipe tunnel in the center of the double bottom will reduce the ability of the bottom to resist the total longitudinal bending and local loads. The pipes in the pipe tunnel and their supporting structures will affect the stress distribution of the hull. At the same time, the pipe tunnel structure has a small space and is arranged at the bottom of the cargo hold, which places high requirements on the shipyard construction operations, and increases the difficulty of control in aspects such as ventilation and safety. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a container ship cargo hold structure and a container ship without a pipe tunnel, eliminates the pipe tunnel structure of the double bottom, moves the relevant piping system in the pipe tunnel into the cargo hold, and adds relevant structures to ensure that the piping system will not be hit when the cargo hold is loaded with containers. The construction of the piping system is convenient during the construction phase of the ship, and the construction safety is improved.

[0005] The object of the present invention is achieved through the following technical solutions: a pipeless container ship cargo hold structure, arranged above the double bottom structure of the container ship, comprising:

[0006] Bottom ballast tanks are provided between the inner bottom plate and the outer plate of the double bottom structure;

[0007] Side ballast tanks are located on both sides of the cargo hold structure;

[0008] The piping system is arranged inside the side ballast tank.

[0009] The cargo hold is arranged above the bottom ballast tank and in the inner area of ​​the side ballast tanks on both sides, and multiple containers are arranged inside.

[0010] Preferably, the bottom ballast tank is divided into a left bottom ballast tank and a right bottom ballast tank by the centerline of the ship.

[0011] Preferably, the piping system is arranged on the longitudinal wall of the side ballast tank on the cargo hold side.

[0012] Preferably, the piping system arranged inside the side ballast tank includes at least a fuel system piping, a low-sulfur fuel system piping, a bilge water piping system and a ballast water piping system.

[0013] Preferably, a shielding structure is provided above the pipeline of the side ballast tank close to the cargo hold.

[0014] Preferably, an inspection passage is provided below the shielding structure.

[0015] In addition to providing a pipeless container ship cargo hold structure, the present invention further provides a container ship provided with the cargo hold structure.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] The present invention provides a container ship cargo hold structure and ship without pipe tunnels, which eliminate the pipe tunnel structure in the double bottom and move the pipeline system required to be arranged in the pipe tunnel into the cargo hold, thereby improving the safety of construction and ensuring the integrity of the ship's pipeline system.

[0018] The present invention increases the bottom ballast tank by removing the pipe structure set in the double-bottom bottom ballast tank, facilitates the adjustment of the ship's loading conditions, and has strong operability. The present invention increases the shielding structure of the pipeline and sets a maintenance channel below it. At the same time, considering the crew's maintenance of the pipeline, the inlet and outlet channels are designed at both ends of the channel, which can be well maintained under the conditions of loading and unloading in the cargo hold, and the maintenance is convenient, and the replacement of pipelines or valve accessories is convenient. The present invention has strong adaptability and is suitable for all container ships. BRIEF DESCRIPTION OF THE DRAWINGS
