Dear all, I am interested in the sequence of events that would have taken place in the engineering department immediately after the collision. Going from full ahead to a crash stop (or full reverse depending on which testimony you prefer) unexpectedly in the middle of the Atlantic would have caused quite a few problems one would imagine. I have recently read 'Down Amongst the Black Gang' which had an excellent summary of the events that may have taken place but raised some more questions I share with you now. Regarding the condensing arrangements, from my reading the electrical dynamos exhausted into a surface heater which prewarmed the feedwater and condensed the exhaust from the dynamos. With the main engines suddenly out of action, how long did the engineers have to change over the dynamos to the auxiliary condenser before the supply of feedwater returning from the main engines ran out? As the boiler rooms flooded, I imagine it was necessary to isolate the steam supply from each one. Was there an arrangement for doing this? Did the boilers continue to be stoked or were they left to burn down and produce less steam? Was it safe to leave a boiler unattended with no one to monitor water levels? There is testimony of steam venting from the forward funnel early on after the collision. Do you think this was due to an excess of pressure due to the crash stop, or a deliberate venting of the boilers in boiler room 6 or 5 as they flooded. If it was an automatic pressure relief, wouldn't all the safetys have lifted? Finally, given the complicated arrangement for distributing steam from various boilers to auxiliary systems like pumps and dynamos, how would you imagine the engineers had the system arranged? Did they take individual feeds from each boiler or keep everything hooked up to the main steam lines and take a feed off that? Looking at the plans, there would have been some boiler rooms lost early to flooding that had auxiliary connections whilst others like boiler room 3 that only had connections to the main steam lines but would have stayed dry for quite some time. I understand we are heading into educated guesswork here as there seems to be little evidence from the survivors on these more intricate details. I'd be very interested to hear the thoughts of everyone on this fascinating subject. Many thanks.
