The scope of claims for utility model registration shall be amended as follows. ■Scope of Claim for Utility Model Registration In a ballast discharge pipe device for discharging ballast from a ballast tank to the outside of the ship from a bell mouth provided in the ballast tank using a pump, the discharge side piping of the pump is vertically erected. By guiding the pipe to the upper deck and interposing a flow meter in the middle, the straight pipe section on the inlet/outlet side of the flow meter is made as long as possible, and a siphon breaker valve and a discharge control valve are installed in the middle of the pipe on the upper deck. and a ballast discharge pipe device, characterized in that the outboard valves are sequentially installed and then piped to be lowered to the overboard discharge position.

Claims

[Scope of utility model registration request]

In a ballast discharge pipe device that discharges ballast from a ballast tank to the outside of the ship from a bell mouth provided in the ballast tank using a pump, the discharge side pipe of the pump is vertically raised and guided to the upper deck, By installing a flow meter, the straight pipe section on the outlet side of the flow meter was made as long as possible, and a siphon breaker valve, discharge control valve, and outboard valve were sequentially installed in the middle of the piping on the upper deck. A ballast discharge pipe device characterized by having piping lowered to a rear overboard discharge position.
