#46182, "RE: Olympic Tank room roof Object- Part 2" In response to In response to 4 Sat Apr-21-12 07:27 AMby bpread
If your contention that there was indeed a battery room on early Olympic and Titanic then it should appear in other period technical publications. Let's talk about the modern reference, "Titanic the Ship Magnificent". This was compiled using a multitude of period technical references. A number of these references had conflicting information and the authors had to do intensive research to determine the truth in those cases. It was written by some of the foremost experts in the construction of the Olympic Class ships. However, a main battery back-up is not mentioned. I won't comment about Sauder and Stepenson's opinion of The Shipbuilder. I will say that "Titanic the Ship Magnificent" is far from being a reference which was "cobbled together" (not that you suggested that about TTSM).
If your theory is true then there should be information available about this main battery room from multiple sources. As Bill pointed out, a battery back-up for the telephones would have been small; certainly nothing which would require an entire room. What we're talking about is a much larger system.
What if the object is nothing more than the accommodation ladder shown on the rigging plan? The problem with trying to base a theory using a very poor quality photo is that it leads one astray very easily.
Here's a question: We have photos of the roof of the tank room during the period of Olympic's career when there actually was a battery room on A deck and this structure is not there. That would tend to suggest at the least that this object didn't have the function you propose and likely that it was just something temporarily stored on the roof.
I actually love pondering new theories. The first threshold they have to meet is: "Is it possible?" Once that is reached then the next threshold is: "Is it plausible?". After those two are reached then it has to rise to the level of "Is it likely?". As far as I can see, your theory hasn't passed the level of "Is it possible?" because there was no main battery back-up or room to contain it on early Olympic or Titanic.
