Painting & preservation

Service Description

Painting and corrosion control is a continuous process combining regular maintenance, scheduled dry-dock overhauls, and specialized teams to combat rust. The strategy includes removing rust, applying primers and specialized paints like haze gray, and using barrier protection to prevent moisture and oxygen from reaching the metal surface. Students will learn the Maintenance and repair Process of: • Regular maintenance: Sailors conduct daily preservation work, which includes touch-up painting, sanding, and cleaning. • Dry-dock overhaul: Every five to seven years, ships undergo major maintenance in a dry dock for repairs and repainting. • Rust removal: Any rust deposits are removed, often by stripping the old paint to expose the corrosion underneath, before new coatings are applied. • Specialized teams: Programs like the Corrosion Control Assistance Team (CCAT) on ships that provide dedicated teams to focus on preservation tasks. Painting and barrier protection: • Barrier protection: Paint forms a crucial physical barrier that prevents moisture and oxygen from reaching the steel hull, which causes rust. • Haze gray paint: This is the standard paint scheme for surface ships and is critical for both camouflage and preservation. • Specialized coatings: Modern preservation involves transitioning to advanced paints, such as 1K Polysiloxane, during dry-dock maintenance. Other methods • Cathodic protection: This technique uses sacrificial anodes on the hull that corrode instead of the ship itself, which is highly effective in marine environments. • Advanced technology methods like laser cleaning for rust removal.
