What is a critical task performed during drydocking that involves removing old paint and rust from the ship's hull before applying new coatings?

The critical task performed during drydocking that involves removing old paint and rust from the ship's hull before applying new coatings is surface preparation, primarily achieved through abrasive blasting (also commonly called grit blasting or sandblasting). Surface preparation is the process of cleaning and treating the ship's hull to create an optimal substrate for the subsequent application of protective coatings, ensuring strong adhesion and long-term performance of the new paint system. Abrasive blasting is a mechanical....
