Final answer:
Inboard tank XFER pumps become uncovered at different quantities for the inboard and outboard tanks. The inboard tank XFER pump becomes uncovered when the quantity of ballast water in the tank is too low for it to function effectively. The outboard tank XFER pump becomes uncovered when the quantity of ballast water in the tank is too low for it to transfer or discharge.
Step-by-step explanation:
Inboard tank XFER pumps become uncovered at different quantities for the inboard and outboard tanks. When the inboard tank XFER pump becomes uncovered, it means that the pump can no longer pump ballast water from the inboard tank to the outboard tank. This usually happens when the quantity of ballast water in the inboard tank is too low for the pump to function effectively. On the other hand, the outboard tank XFER pump becomes uncovered when the quantity of ballast water in the outboard tank is too low for the pump to transfer the water to another tank or discharge it.
