What is PSPC coating?
Protective coatings are essential for ease of maintenance and keeping ships in good condition. In order to maximize the effectiveness of the coatings, it is important to improve the quality of coating application at ship construction stage.
How do you stop a ballast tank from corroding?
Epoxy and modified epoxy are standard coatings used to provide protective barriers to corrosion in ballast tanks. Exposed, unprotected steel will corrode much more rapidly than steel covered with this protective layer. Many ships also use sacrificial anodes or an impressed current for additional protection.
What do you check in a ballast tank inspection?
The tank inspection is able to demonstrate structural damage, the condition of coatings, the degree of corrosion, and the condition of the internal infrastructure of the tank (pipes, manholes, sensors).
What are the safety precautions during ballast water exchange?
Safety considerations
- avoidance of over and under-pressurization of ballast tanks ;
- sloshing loads in tanks that may be slack at any one time ;
- maintain adequate intact stability in accordance with an approved trim and stability booklet taking into account the free surface effects on stability;
What does Pspc stand for?

What is the coating condition with only minor rusting?

What is the coating condition?
A coating condition survey (or ‘coating survey’) should be used as a proactive measure in the protection of any previously coated structure. For example, this may include surveying coatings in the offshore environment or on bridges that are at risk of corrosion.
What are the conditions to be taken before ballast operations?
