If its a section of pipeline which has suffered mechanical damage bad enough to require full replacement of the damaged section then have fabrcated a clad pup-piece of sufficient length to replace the damaged area. Then hyperbarically cut the latter and weld in place the pup-piece using the approved weld procedure.

I thought you knew that and were looking for something suitable for an emergency repair. Not to say that a claded repair clamp could not be developed.
Nigel,
The clamp system was designed as a more cost effective alternative to divers and hyperbaric welding, but if the water depth allows, why not?
