発明の名称 (英語) SHIP BUOYANCY CONTROL SYSTEM
発明の概要(英語) The tank (10) of a ship (1) has an inflow port (6) and an outflow port (7) that are opened in the ship bottom (13) and arranged at an interval in the advancing direction of the ship body. An opening closing means (9) is provided to each of the inflow port and the outflow port. The opening closing means closes each of the inflow port and the outflow port so as to ensure ship body buoyancy by means of air in a space in the tank. With the inflow port and the outflow port, outboard seawater is captured through the inflow port using the advancing movement of the ship body and seawater in the tank is allowed to flow overboard through the outflow port. A partition wall (2) forms in the tank a weir extending in the width direction of the ship body to section the area in the tank into an inflow area (3) and an outflow area (4). The tank, the partition wall, the inflow port, the outflow port and the opening closing means constitute the buoyancy control system of the ship. Accordingly, ballast water is replaced with seawater with a simple construction without depending on a forced replacing drive device, and a high ballast water/seawater replacing rate is attained.
