Water tight door
- For a door to be truely water tight it must be enclosed on all six sides.
- But it was generally found unacceptable because passengers and the crew needed to be able to access all parts of a ship without being prevented.
- Boiler rooms and engine all had hydraulically-operated vertically-sliding water tight doors
- The doors could be lowered into place by many different methods, closing off compartments from each other.
Boilers
- The titanic had 25 double ended triple furnace boilers.
- 4 single eneded
- making a total of 162 fireboxes (furnaces)
- each had a stoker
- The boilers had to be kept in steam the whole voyage
- approximately 600 tons of coal was used in a day
- Which all had to be shoveled out from below the boiler
Engine
- proven and reliable but not the new turbines
- they settled for a traditional system
- had 2 huge triple-expansion steam engines
- uses recycled steam and does not waste
Funnel
- each vessel was equipped with a funnel
- each one was elliptical and measured 25ft
