When a cruise ship is in dry dock, it means that the ship is being serviced and maintained. Dry dock is an area of water, usually within a harbor or shipyard, that has been enclosed by docks and walls to keep water from entering. Cruise ships are taken into dry dock for a variety of reasons, including repairs, maintenance, and upgrades.
Cruise ships may need to be taken into dry dock for repairs due to wear and tear on the vessel caused by constant use. If a cruise ship has been damaged due to weather or other accidents, it too may require repairs in dry dock. Regular maintenance must also be performed on cruise ships to keep them running smoothly and safely.
This may include cleaning and painting the hull of the ship as well as replacing worn out parts such as pumps or propellers. Cruise ships will often undergo upgrades while in dry dock such as the installation of new amenities or technology.
Dry docking generally takes several weeks depending on the type of work needed to be done on the ship. During this time there will be no passengers onboard as all activities are suspended until the repairs are complete. Cruise lines are well aware of this downtime and plan accordingly to ensure minimal disruption for passengers when scheduling dry dock visits for their ships.
