I'm curios as to which rigs they are recovering.
The Occidental Piper Alpha is a grave and i wouldn't be surprised to find that the Deepwater Horizon as been registered the same.
Having a topside on the seabed is never a good idea, they usually decommission by cutting them off at the surface and loading them onto barges.
The only scrap topsides i can think of on the seabed would be in the Caspian sea or perhaps off the coast of Africa. This is a post id love to hear more about.

ahh OK got it

As a salvage vessel of the future i think it might end up spending a lot of time moth balled and costing a fortune to support.

The LR5 Royal Navy submarine rescue sub was a planned recovery system which cost a fortune and is use could be counted on the fingers of two hands. We sold it to Oz.
