#50428, "RE: Number of windows in Chart room and Pilot's room" In response to In response to 17
After looking at both Bruce's G/A the digital photos of the H&W 401 plumbing plan, I honestly don't know what they could hope to gain from access to via those boiler room fan trunks at the Boat deck level other than light from above, and ventilation to those to compartments via air being drawn in through the door louvers by the suction being created by the negative pressure within the BR fan trunk. The majority of the vertical fresh and salt water supply and return lines and a number of the hot water supply tanks are all located within the fidley trunks, with others lines running up inside the engine casings. At none of these drawings shows anything within the fan trunks -- not a positive proof of the complete absence of piping or electrical runs within these spaces, but telling none the less. The fidleys were the idea location for such systems. They were chock full of ladders and platforms providing easy repair access from within for all of this stuff, while also providing a direct, if arduous means of emergency escape from the boiler rooms straight up to the Boat Deck.
