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 structures, 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, cleaning, and repairs to be conducted without the challenges posed by water. Dry docks are crucial for the upkeep of various types of vessels, including cargo ships, naval ships, and luxury yachts.
