I could not understand the " valve " statement either hence my question mark on my write up.
Between the Captain and the Cruise Director perhaps it was lost in translation as the saying/ get out clause goes.
As BP says the CS ( controlled start ) motors used to be hydraulic but have in the last few years gone over to electric ones.
I find it very difficult to get the true picture of these failures because of the Cruise Lines P R machines which allways issues the BBB statements ( Bullshit Baffles Brains ) as of course it's allways a " minor glitch " or a " minor reprogramming necessary " , it's never " anything to get concerned about " blah blah blah etc.
Hundreds of millions of pounds weekly are generated by these ships and as such every defect is, of course of a minor nature only, you understand.
The only way to get at the truth is via an MCA report or US coastguard inspection etc which seemingly takes months to come about.
I know that overriding devices are supposed to counter human errors but we all know that past examples of same would indicate otherwise both down below and up top and if you look at recent ship major, major happenings this is indeed the case with some happenings resulting in a total loss of the ship down 100% to human error.
So when and if we shall ever be educated as to why these Anzipods are prone to these failures remains to be seen.
It is, after all in all our interests and safety to make these failure reasons be known to all who may come in contact with these problems so as to apply the old adage " prevention is better than cure "
But sadly it is my belief that because of passenger revenue alas this may never be the case.
