That job has been going on for ages it was announced initially in 2005 as a concept http://www.timesonline.co.uk/tol/news/uk/article432993.ece.
When Fugro were on the job it was a subcontract down from TS Marine.
Basically it is about three hours out from Vigo in around 1200m of water.
If it is still the same set up there are two rov systems one monitors the grapple going in and out of the shiphold the other has a big workpack on it which opens and closes the grab.
The copper is then dumped into big skips sat in the hold of the vessel and when full the grab is disconnected and the skip is lifted up and dumped on the deck.
It was quite an interesting job certainly something different. It was subsea resources baby that is for sure as John Kingsford was onboard the vessel for most of the time.
If it is still ongoing the success must low on this project. 😯
