Document Type and Number:
WIPO Patent Application WO/2019/000798
Kind Code:
A1
Abstract:
The present invention relates to the technical field of ships, and in particular to a topside ballast tank ballast water bleed-off system, the system comprising a topside ballast tank arranged at the top of a ship, and a seawater tank arranged at the bottom of the ship, wherein a water outlet is provided at the bottom of the topside ballast tank; a water inlet is provided at the top of the seawater tank; a water discharging port in communication with the outside is provided on a side face of the seawater tank; the water outlet is communicated with the water inlet via a bleed-off pipe; and the bleed-off pipe is provided with a valve. When ballast water in the topside ballast tank needs to be discharged, the valve is opened to enable the ballast water in the topside ballast tank to be automatically bled off to the seawater tank under the action of gravity, and all the ballast water in the topside ballast tank can be discharged completely. As a stripping pump is not provided, the consumption of shipbuilding materials is reduced, and the shipbuilding costs are lowered, thereby achieving a good economic benefit in the long run.
