Because operating conditions involve ballasting with warm/cold seawater and wet/dry cycling they are always liable to severe corrosion. The condition of the ballast tanks does determine the service life of the vessel.

The severity of corrosion in ballast tanks and the high numbers of ship losses due to structural failure following corrosion damage have increased the attention that Classification Societies and other regulatory bodies pay to ballast tank coating condition.

The correct choice of ballast tank coating at both new building and maintenance stages can have a significant impact on the structural integrity of the vessel and its operational profitability.

PPG Marine Coatings range includes a selection of ballast tank coating systems aimed at maximising the life of the vessel. These are approved by the major Classification Societies.
