Ballast tanks.

The ballast tanks contain seawater, or ballast water, which is pumped into or discharged from the ship during cargo transfer, usually in harbors and nearshore waters. When cargo is unloaded from a ship, the weight of the ship decreases, so seawater from the surrounding waters is pumped into the ballast tanks to compensate for the decreased weight.Table of Contents Page No. Personnel iii Foreword iv List of Tables vii List of Figures vii 1.

The water is used to maintain ship …Many vessels take on ballast water to improve balance, stability, and structural integrity when they are sailing without cargo, for example. When the vessel is loaded, the ballast tanks are then emptied—and this is where problems can arise. As ballast water is taken on, thousands of organisms living in that water are brought on board.Marine. Ballast Tanks. When it comes to ballast tanks, a long service life and low maintenance requirements can mean significant savings. That’s what you get with our certified ballast tank coatings. The ballast tanks are probably the largest area of structural steel on your vessel, and the water inside can be highly corrosive if left unchecked.

tonnes of ballast water is transferred annually throughout the world and approximately 10,000 unwanted species are carried in ships ballast tanks daily.
