Ooh, that's good! Yet again the opportunity to learn something new - and all because of QE2!
Firstly, Isabelle - well spotted! (Regarding the expansion joint that's been identified with the marking)
I wonder, did you notice any others on the Rotterdam's superstructure?
Then Bob C - I remember clearly your explanations about QE2's superstructure, hull and tumblehome - that is what's it's called, isn't it?
Not forgetting the transitional join, either!!
If you and anyone else, has the time, please could you 'talk' about the why, how are they made, what are they there for, and other important things / questions about expansion joints - what exactly might stress it enough to make it 'crack or run' (can/do they actually break, and how far could the metal split etc? etc).
If Rotterdam's got at least one, then mightn't QE2 have one or two as well?
Thank you
Rosie
