The actual BOP's valves failed to work. This is the problem. It doesn't matter how many control systems or backups you have or if they are electronic, hydraulic, pneumatic, manual or acoustic.
Ok here's an analogy "It doesn't make any difference which hand you use, if the light switch is broken, the light won't come on will it."
I can't be much cleared than that.
