US Navy-how are 2 compartments numbered, both are on centerline, yet one overlaps into other?

Question

1 is L shaped, the other is a rectangle. the two compartments fit together to form a rectangle. the centerline of the ship divides the smaller compartment down its middle, as well as cuts through the L shaped compartment. for example on deck 1, living space, the forward most frame is 50th, so the compartment numbers would be " 1-50-0-L" , but can you have two compartments be the same number? or is it a trick question and no ship would be built like that?

Answer 1

Too long ago. But whenever I had a problem with this I just went through other drawings until I found something similiar. From memory this happened with cupboards or cubicles all the time although you would not have the L. The other answer might be correct or what if it went like this. 1-50-0.1-L 1-50-0-L
Probably wrong i last worked on an FFG approx 1992.
just check other drawings.

Answer 2

Actually, I've seen something like what you describe on a number of ships. For one example, my aircraft maintenance spaces on the USS Yorktown had the same frame, deck, stardboard/port numbers and letters, except an A and B were added to the two separate compartments. We entered the B compartment through the A compartment.

Using your example 1-50-0-L-A and 1-50-0-L-B would be over the hatch. The A compartment would be the one emptying into the passageway, the B one would be the interior one with no exit to a passageway.
