Pump-room bottom protection-Reg.22

• In case of pump-rooms whose bottom plate is located above the baseline by at least the minimum height required in above paragraph, there will be no need for a double bottom construction in way of the pump-room.
• Ballast pumps shall be provided with suitable arrangements to ensure efficient suction from double bottom tanks.
• If the flooding of the pump-room would not render the ballast or cargo pumping system inoperative, a double bottom need not be fitted.
