question: How does a modern warship get cleaned?
comment: It wasn't really punishment to wash the deck. It was something everyone had to do on a regular basis. Modern sailors clean and maintain their equipment constantly. If you aren't fighting, or training to fight, you're probably cleaning or painting something. Then every several years the ship goes in for an end-to-end overhaul at a yard.
passages: BULLET::::- Underwater hull cleaning to remove fouling organisms which increase drag, and therefore reduce top speed and increase fuel consumption. Such cleaning may be of the entire hull or parts thereof, particularly propellers, shafts and thrusters. The underwater hull may be inspected prior to cleaning, and the amount of cleaning done may depend on the inspection results. Hull cleaning may be done by divers using hand held or self-propelled mechanical brushing equipment, water jets or scrapers.
   BULLET::::- Non-destructive testing and inspection included fouling surveys, inspection of known or suspected damage to structure, equipment or coatings, and inspection of repairs. Several methods may be used, including visual inspection, video recording and magnetic particle testing.
  
  BULLET::::- Underwater painting is done to repair paintwork after repairs, or where small areas of paint have been damaged or have worn out. Suitable paints are applied by the diver using brush or roller.
   Welding, sandblasting, painting, and other maintenance work contribute pollution. Ship hulls are made of steel and have many layers of anti-fouling and anti-corrosion paint. Shipyards around the world paint ships, usually by airtight spraying or by thermal spraying. 
   Back in the vessel, Oswald is assigned to scrub the ship's main floor and polish the cannons. To make his jobs more interesting, he comes up with an eccentric method by riding behind two runaway tabbies and at the same time scrub the floor with brushes attached to his feet as he gets pulled. This strategy turned out to be very difficult to control as it results in Oswald accidentally stripping paint off some life boats as well as knocking down the admiral.
   BULLET::::- Fiberglass repair, can be hull repair or propeller shaft protective coating repair. Repair of fibreglass shaft coating is generally done in a dry habitat mounted over the shaft, allowing access through the open bottom for the divers. The shaft is first cleaned before wrapping with a new layer of sheathing.

   The Saginaw Valley Naval Ship Museum was able to obtain this Navy destroyer because of the vast amount of volunteer work put in by the board members and many outside volunteers as well. A permanent dock was built for the museum. About of paint in two different shades of gray were ordered for the painting of the dock. While waiting to obtain the last of the additional paint that is needed to completely repaint and restore the USS "Edson" color, the museum received word that those who are on the Navy's delayed entry program and are waiting to be shipped off to boot camp are willing to volunteer in the restoration of the destroyer.
   Workers at the dockyard performed eight years of restoration work on the MV "Havengore", the ceremonial vessel that carried the body of Winston Churchill during his state funeral. In addition the dockyard is acting as custodian of artefacts, masts and rigging from the "Cutty Sark" and the "Medway Queen", while their hulls are being restored elsewhere. 
  
  BULLET::::- Records of the ships built at Chatham go back to 1646.
   While in Omaha, restoration work was done by volunteers including a fresh coat of paint, unstepping the mast for storage, and work on all decks. The bulkheads below deck were lined with rows of walnut plaques with the names of those hundreds of individuals that had given of their time and money to restore and save the LSM. There is evidence on every deck, in every compartment, from the galley to the engine room that many hours of restoration had taken place by dedicated workers.

   BULLET::::- August 2015 to April 2016 – Planned Incremental Availability – 4 Mk-38 added (2 on small bow sponsons, one on stern on old CIWS sponson and one starboard ahead of elevator four).
  
  These repairs add up to over ten years of repairs. And the longest active duty period of 29 months between repair periods. Between being built and repaired she has spent most of her life in the yard. Not haze gray and underway.

   On January 9, 2017, USS New Orleans moved into the Dry-dock Ships Selected Availability (DSRA) at BAE Systems shipyard. The crew and hundreds of contractors went through an extensive list of repairs and upgrades to the ship’s hull, tanks, ventilation, auxiliary, propulsion, and combat systems. After 10 months being dry docked, on November 28 New Orleans was undocked and begun preparation for work ups. 
   Early photos show square windows instead of today's portholes. For most of her life the upper passenger cabins were painted white and had wooden doors; all have had layout improvements at some time in the ship's life. Sailing in all weathers in salt water can cause pale brown rust streaks to appear by the end of each season, so cosmetic painting and improvements are done annually as the ship is drydocked and checked by the Department for Transport.
   A ship's galley, pantry, and eating areas are notoriously hard to keep clean and sanitary, and this activity keeps the steward's assistant busy for much of his time. The steward's assistant must clean the ship's mess and officer's saloon, and the gear in both. This includes keeping the decks clean by sweeping and scrubbing. The steward's assistant disposes of trash and keeps garbage cans clean. Other tasks could include defrosting and cleansing refrigerators, cleaning brightwork and woodwork, and removing grease and finger marks from paintwork.

  Whatever construction is completed during fitting is also dependent on the shipyard’s capabilities and the availability of equipment prior to floating. For example, "Queen Mary 2" was originally to have its propeller pods installed prior to floating, but this was not done until the fitting-out stage.
  
  Contemporary ship construction usually has the vessel returning to drydock several times for installation of propulsion mechanisms (such as propulsion pods in contemporary vessels) and for the painting of surfaces below the waterline.
   BULLET::::- For additional treatment of bilge, grey water, and engine water, the "Benjamin Franklin" is fitted with an additional decanting tank. This decanting tank is able to separate water from undesirable liquids, by letting all of the liquids settle. The waste products in the liquids are then removed and the remaining liquid is sent for further filtering.
  
  BULLET::::- The "Benjamin Franklin" is fitted with CMA CGM's Fast Oil Recovery System, which is used to manage pollution on board the vessel.
