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.

Interesting.
Transocean and Infermer were the two companies who operated the first salvage vessel i worked on Deepsea worker an old Sedco drill ship (337 ?).
Salvaging tin from torpedoed/sunken liberty ships from the war Autolycus and Namur. The salvage work also covered vessels such as the John Barry, HMS Edinburgh and survey of Lusitania.
