A dry dock is a specialized facility used for the construction, maintenance, and repair of ships and boats. It is designed to allow vessels to be taken out of the water, providing a safe and controlled environment for workers to access the hull and other underwater components. Dry docks can be either floating or fixed, and they are essential for ensuring the longevity and safety of maritime vessels. When a ship enters a dry dock, the water is drained, leaving the vessel supported by blocks or a platform. This process allows for inspections, repairs, and cleaning of the hull, as well as maintenance of propellers, rudders, and other critical parts. Dry docks are crucial for the shipping industry, as they help maintain the efficiency and safety of commercial shipping and naval operations.
