PURPOSE: A gravity type integrated type ballast water treatment apparatus for a floating type offshore construction is provided to increase the use of a deck on the floating type offshore construction, and to reduce the production costs of the floating type offshore construction as an injection device of active materials does not need to be installed since active materials are supplied into a ballast line by gravity. CONSTITUTION: A gravity type integrated type ballast water treatment apparatus for a floating type offshore construction comprises an active material storage container(110), and one or more of ballast tanks(151). The active material storage container injects active materials into a ballast line(130) in which ballast water is flowing by storing active materials which exterminate aquatic organisms in the ballast water. One or more of the ballast tanks are installed in a hull of the floating type offshore construction(100), and the ballast water is stored and discharged. The active material storage container is installed in the upper area of the ballast tanks. |
