Great photos and descriptions of the engines. Much appreciated by a marine
engineer.
Regarding the question of cargo doors in the ships sides.
It is also most likely that were single doors. It is hard enough to get a
single door to seal all the way round, let alone a joint down the middle of
double doors. It is also easier to clamp a single door shut from the inside
than a double, which would require a big beam(s) to be put in place across
it, after closing.
I can only tell you that on more modern ships they always open inwards. If
they opened outwards they would be very difficult to operate and maintain.
Opening inwards the rubber seals can easily be repaired as required and the
joint area greased each time before closing again. There are large clamps on
the inside to hold it closed. This arrangement also means that the hinges
were protected and maintainable, on the inside of the hull.
Bearing in mind the high level of innovation and technical expertise used in
the design/construction, it is my guess that they were single doors opening
inwards. I MUST STRESS, JUST MY GUESS.
All the very best and keep up the good work on a your brilliant site.
