Legend/KEY to deck plans

Thanks. You dispelled my doubts.
And you can tell me more about the room next door. It's about dicharge recess. What was its function? What was the purpose of the pipes coming from the turbine and running to the side of the ship? What role did the destilers on the other side play?
The discharge recess was the area where the pipes carrying the cooling water from the main condensers exited the hull. Its not a room as such just an area containing the outfalls. The large blocks on the side of the turbine are the main condensers which used huge amounts of seawater to cool the steam back to usable water.

The distillers were for producing feed water to top up the boilers- not for potable use. The boilers required very pure water to reduce corrosion with minimum contaminants. Largely they reused the condensed steam but unavoidable losses meant that a small shortfall had to be constantly made up.
Without your help in the forum I would probably never have found so much interesting information about the Titanic. I know a lot about the ship in general. But after analyzing the plans, I see that there is still a lot to analyze.
As I wrote earlier, information on the Titanic in Poland is very limited. Here, I learn something new all the time :)
Welcome back. I have a question about Post Office and Mailroom. There are Regs Letters at the post office on boat G. What does it mean? Do I understand correctly that Letter Cage is just letter baskets? In the Mailroom on the Orlopdeck there is a Specie room. What was the room for? Was the engine opposite the stairs a hoist engine? Were newspapers printed on the ship or taken from the port?
Damian, taking your questions in order. Registered Letters required a signature from the recipient and were usually important correspondence that the sender paid a premium for special service. Letter cages held unsorted mail. The specie room was a secure vault for the carriage of high value items like gold, silver or other precious metals in bulk. I don't think it was in use on this voyage. The motor you ask about was probably the hoist motor, yes. And finally Newspapers as we know them were not printed on board. Some 'headlines' were received by the Marconi office and displayed on notice boards I think but that was about it.
Thanks. This is what I ment. I always have a problem with these shortcuts.
Or maybe you could help me with one more thing. Passengers' cabins are located on this side deck on the port side. There is information "Portable 3rd class White Star Pattern". What's this about?
I'll have to take a guess and say that cabin area was made up of temporary cabins that could be disassembled if the room was required for storage or open 3rd Class berthing. I believe White Star had a standard design of convertible cabin walls for this purpose?
Others may know more.
The paint store is obvious. A steel ship needs endless painting, so she's touched up as often as possible. I once knew a man who had a paint locker on his small, steel yacht. He used to patch up the most minor dings, such as those made by the anchor.
Hello. I will need your help again. He is currently reviewing Tank Top plans. There are a lot of symbols "P" - Plate over manhole. What were these hatches for? Is this related to the bilge tank? The "DP" symbols are arranged on the same deck - Drain pot. What was it for? Is this also about bilge water?
The manholes were access points into the double bottom tanks for maintenance, painting, inspection, etc. The drain pots were depressions in the tank top which, as the name implies, served as drain water collection points for the bilge system.
Thanks. I just expected such an answer. You know something about "Line at center of boilers", "Line where tank side crosses landing", "Sight edge 5 '- 0" parallel to ship's side "," Line at tank side "," Line at panting deck "? What is" panting deck "
