Sotra Anchor & Chain, one of the world's largest marine chain suppliers, supplied the 1000 metre-long, four-tonne chain used to hold the barge which pulled the 290 metre-long cruise ship upright.
Jan Vindenes, the company's general manager, said he has been "excited but not nervous" during the 19-hour operation.
"It would have been a disaster of course," he said of the prospect of the chain snapping. "But it didn't happen and I was pretty confident it was strong enough."
He refused to be drawn on how much of the record-breaking €600m cost of the salvage operation had gone on the chain.

"We made a nice profit," he said. "It's obviously not the biggest chain delivery in the world. It's not our biggest delivery this year either, but it was a nice order."
