'Please excuse my ignorance'
What do you think would make a cam shaft split?
Might there be implications then for other ships with the same shafts?
(Incidentally, and bordering 'on topic!) - On Queen Victoria in August, people from Fincantieri flew to the Baltic as there was a broken 'bit' on '#1 tender' davit. The ship's crew worked hard, they replaced the part - overall, no time was lost.
In my book, the technical guys on Cunard ships are second to none!)
