Q

What do the Seawater Compensating Stations do?

A

Seawater is pumped into the fuel storage tanks by the fireman system to assist with buoyancy and stability.

As fuel is removed, seawater is added automatically to retain buoyancy. Since water is heavier than fuel the ship will sit lower in the water when we are running low on fuel.

As we refuel the ship, the fuel pushes the seawater outside of the ship returning the storage tanks to a full level of fuel.
