ship compartmentalization: Ships aren't compartmentalized this way. Warships and passenger vessels have much smaller compartments, for different reasons (damage control and for staterooms). Bulk cargo vessels and container ships have much larger ones. Tankers, of course, have tanks. The line marked "A", waterline, is not the waterline. This profile doesn't exist. Cargo vessels (except car carriers), have a much smaller superstructure way aft. Military vessels have the superstructure amidships. Passenger vessels have the wheelhouse forward and the superstructure more or less the same height throughout. The note on composting toilets is an irrelevance. The weight of urine is inconsequential and ocean going vessels dump it overboard except near land. You place toilets where convenient for passengers and crew, not for design or operational convenience. This comment is typical of your inability to think like an engineer -- I would reason as follows: A crew member might excrete a kilogram or two a day. A crew of twenty on a cargo ship of 20,000 deadweight tons might, therefore, excrete, 1,000kg on a twenty-five day passage, which would be halfway around the world. Therefore, the maximum imaginable weight of urine would be 1/20,000 of the weight of the cargo. This tells me without any sort of accurate calculation, I don't need to pay any attention to the weight of urine. small remark: the weight of urine/feces wasn't the issue here, the reason I mention the use of composting toilets is just because feces/urine is generally disposed into the sea/river where it pollutes it, and as a additional problem, nutrients that are otherwise suitable for agriculture get lost. I would think that the weight btw remains the same, given that food, ... needs to be present on the vessel already, so the only thing that happens is that the food is digested and converted into other substances. Perhaps that water urine may built up as extra weight, if it's assumed that water is harvested on the vessel (which is unlikely). KVDP 17:11, 7 July 2010 (UTC) "Decks above the waterline do not need bulkheads" is nonsense. That line of reasoning is the principal reason the Titanic sank (her bulkheads did not extend high enough and the water gradually worked over them as she went down at the bow). "The deck at the waterline should always be watertight" is also nonsense. There is often no deck at the waterline, because the interior design is not concerned with waterline location and, in cargo vessels, the waterline changes with load. In fact, all decks should, in principle, be equipped to be watertight if required. The placement of sleeping quarters and the galley is for passenger and crew comfort and not to avoid flooding. In passenger ships, crew sleeping quarters and galleys are below the waterline in order to maximize the above waterline volume available for passengers. The engine and machinery space shown is too small -- it might be three to four times this size, in several compartments, in a warship, twice this size and much farther aft in a cargo ship, and also twice as big in a passenger ship.
for the purpose: The main thing I made it for is to show the decks. Aldough the initial image made for the ship floodability article already showed most of the compartmentalization, it did not show the decks. For this, a side view was needed, and at present no such image exists at wikimedia commons. Given that I already needed to make a new image showing the side view of a ship, I thought that it was also useful to immediatelly mark/make clear the general placement of the ship components (ie engine, sleeping quarters, galley, ...) If this was to be done using simple coloring of the compartments to show the general sections they are in (and thus not making it too specific) it would not be overkill for the image (it was btw already pretty empty, given that only the decks were shown otherwise). I did not have any good images to base myself on so I simply put in the text to add the coloring later, and kept to just giving some info in the text (originally by immediatelly writing on the image). Now that the text is added to the image description, the text is easy to correct later, and is no longer an annoyance to someone just wanting to see the decks. The coloring is something I still wish to do, but I don't have any good images/references for this, and I'm also still working on correcting other images. If I can get a good reference, I'll get unto to this after I finished with the other images.
--> image thus needs to be colored soon; text in regards to bulkheads, ... can be kept (won't be uploaded to commons any time soon), and the text is useful to understand positioning of sleeping quarters, ... as mentioned in description text
--> in regards to compartments sizes, ship lay-out not being correct: perhaps the center tower can be put back into place; or otherwise a new plan can be made from the container vessels at http://www.globalsecurity.org/military/systems/ship/container-types. Also, a hybrid can be made using the current rooms in a container vessel, but only for the top section 91.182.117.147 05:35, 8 July 2010 (UTC)
