Description

  The present invention relates to an installation structure and an installation method of a ballast water treatment apparatus in a container ship equipped with a ballast water treatment apparatus for treating and killing or removing microorganisms contained in ballast water for balance adjustment of a hull. is there.

  Ballast water mainly in large ships such as container ships is seawater and fresh water taken in to adjust the balance of the hull. Ballast water is taken into the ballast tank on the ship's side when the cargo is empty, and the ballast water in the ballast tank is discharged at the port where the cargo is loaded, so that the attitude of the hull is kept stable. .

  Ships such as container ships are moving around the world. Containers are loaded and unloaded at each port of call, and at the same time, ballast water intake and drainage are repeated. Therefore, the ballast water is moving around the world.

  By the way, the ballast water contains various microorganisms (floating organisms such as plankton, their eggs, microorganisms such as bacteria), and such microorganisms are in a port of call different from the port where the cargo is loaded. It is pointed out that there is a possibility of destroying the ecosystem and environment of the port of call, and there are concerns about the impact on the human body.

  From this point of view, the International Maritime Organization (IMO) has adopted a convention on the management of microorganisms contained in ballast water (ballast water management convention), which is currently ineffective, At the time of drainage, it is required to kill or remove microorganisms contained in the ballast water, and it is required to mount the treatment device on a ship. In particular, it is required not only for newly built ships but also for existing ships to be equipped with a treatment apparatus for killing or removing the above-mentioned microorganisms of ballast water (referred to as a ballast water treatment apparatus).

  As a method and apparatus for ballast water treatment, for example, a slit plate having a slit hole for allowing the ballast water to pass therethrough is disposed in the flow path of the ballast water, and microorganisms are crushed by a shearing action due to the passage of the slit hole. A method and apparatus (Patent Document 1) using an impact caused by cavitation crushing caused by passage, a method of pulverizing microorganisms by a shearing action by a high-speed water flow in an annular flow path by a cylindrical wall and an impact by a high-speed rotating body, and An apparatus (Patent Document 2), a method of generating cavitation bubbles in ballast water by applying high-frequency vibrations in a part of a flow path of ballast water, and crushing and killing microorganisms by a shock wave generated by the collapse of the cavitation bubbles Utilizing a device (Patent Document 3), other methods for removing microorganisms with a filter device, and ultraviolet irradiation Law, methods utilizing the heating means, the method utilizes a drug other various methods and apparatus have been known.

  By the way, it is desirable to install the ballast water treatment device in an engine room equipped with a ballast water pump. For new ships, the engine room can be designed in consideration of the installation of ballast water treatment equipment, so it is relatively easy to install. However, in the case of existing ships, the engine room already contains the main engine and auxiliary Equipment and other equipment are installed, and there is no room for installing a ballast water treatment device. This requires a lot of labor and modification, and the installation work takes time and costs. Also grows. In particular, the larger the container ship, the greater the amount of ballast water, and the larger the ballast water treatment apparatus for treating it, the more difficult it is to install in an engine room or the like.

  In Patent Document 4, it is proposed that the ballast water treatment device is installed in the steering machine room at the rear of the ship. In this case, although the hull structure and the hull form are not significantly changed, In the case of a ship, predetermined equipment is already installed in the steering machine room, which requires movement of equipment and major modifications, and the installation work takes a long time. Since the ballast water pump is generally disposed on the bow side of the engine room, if the ballast water pump is disposed in the rear rudder room, significant modification is required for piping work.

  Therefore, there is a demand for existing ballasts to be able to install a ballast water treatment device without requiring significant equipment movement or modification.
