Your post reflects a couple points of misunderstanding that seem to be fairly widespread on these boards, so let me take the time to address them.

>> 1. The primary purpose of putting a ship into drydock is to work on the underwater portion of hull and external appendages that are not accessible when the ship is in the water. A "drydock" is a U-shaped well with a caisson similar to the gates of a lock system in a river or canal that closes across the open end so that the shipyard can pump out the water, making the underwater portion of the hull accessible for painting and external appendages, like Azipods, accessible for maintanance or repair work. It's fairly expensive to put a ship into drydock because the yard has to pump out the drydock, configure keel blocks properly to support the ship, flood the drydock, open the caisson, move the ship in, close the caisson, and pump out the drydock while using guy lines to keep the keel in the correct position to rest on the keel blocks, then rig staging so the yard personnel can reach the points that need work. At the end of the drydock, they have to reverse this process.

>> 2. Cruise ships often visit shipyards for maintenance without going into drydock. Most ships probably go into drydock about every second or third visit to the shipyard, primarily to scrape and paint the hull and to do maintenance on rudders and external bearings. Also, a ship that does go into drydock will remain in drydock only as long as necessary to do the portion of the work that requires drydocking. Once that portion of the work is done, the shipyard will refloat the ship and move it to a regular pier to make the drydock available for another vessel.

>> 3. Most ships do some refurbishment of interior spaces whenever they go into a shipyard. At the very least, they usually replace carpeting and other deck coverings in "high wear" areas do whatever painting and varnishing are needed while the shipyard work force is available to augment the work that the crew can do in the allotted time.
