On a ship

Demonstration on the MV Kruibeke

The current state of knowledge about the corrosion problems on board gas tankers is rather limited. Research thus far has focused on problems in the ballast tanks and the hull.

After all, as part of the normal operation of a ship, ballast tanks are often loaded and unloaded with ballast water. When the ballast tank is filled, the seawater is in direct contact with the steel tank wall. When the ballast tank is emptied, a small amount of ballast water always remains in the tank. This means that the atmosphere is always very humid, with a high concentration of chloride in the air. This leads to high corrosion rates.
