Dry docking is a process used to repair or maintain ships and boats. During dry docking, a vessel is taken out of the water and placed on a platform or in a specialized facility called a dry dock. This allows workers to access the hull and other underwater parts of the vessel for inspection, cleaning, and repairs. Dry docking is essential for ensuring the safety and longevity of a ship. It typically occurs every few years, depending on the vessel's age and usage. Regular maintenance during dry docking helps prevent corrosion, damage, and other issues that could affect the ship's performance at sea.
