Broadly speaking, ship repair includes the following: Blasting Cleaning (Blasting) Blasting is a ship cleaning method that is carried out by spraying sand onto the ship's hull with high pressure. The purpose of spraying sand is to remove various dirt or dust that sticks to the hull of the ship. However, of course the sand used cannot be arbitrary. Usually, steel great sand, silica or quartz, plate streal, and overslag are the types of sand that are often used to clean ship hulls. Repainting the Ship After blasting, the next step is to repaint. However, before this process is carried out, make sure that the ship is really in a clean condition. Because the dirt that sticks can cause condensation when combined with paint. As a result, small holes will appear and the paint will peel off easily. Usually, the paint used to coat the ship is a primer, anti-rust paint, and anti-sea animal paint. Hull Inspection and Repair This inspection is usually more focused on the thickness of the ship plate. Ships that have experienced a reduction in thickness from the standard size must be replating. Meanwhile, for ship repair, it can be done by welding. Ship Equipment Inspection and Repair Below the Waterline Some parts that need to be checked include the zinc anode on the ship, the propeller, and the steering wheel. Zinc anode needs to be checked because it serves to inhibit the occurrence of rust. The ship's propeller must be ensured in a straight condition. If bending or cracking occurs, repair it immediately. Meanwhile, the inspection of the steering wheel is checked to see its feasibility.
