Chris Groves – Rescue submarines

Well they’ve been around for quite a while, the Rescue Submarines, so in actual fact the Rescue Submarine … all that’s doing is preventing you from having to do the in the Tower flood and equalise in the Tower and then do the ascent.

What they’re doing is, they’re keeping you at the same pressure that you submarine’s at, so they’ll come down to the submarine, hopefully you won’t have any pressure.

The pressure inside the submarine will be the same as the pressure at the surface and so they come down, they clag onto the top of the Escape Tower, you open up the top of the Escape Tower and people get out of the submarine straight into the Rescue Vehicle.

You shut the hatch and off you go to the surface and you never have that pressure transient at all.

You stay broadly at the same pressure as all the way throughout, so the risk to the individual is very low, and therefore that’s your primary method of escape if you can possibly do it.
