In March 2004, the Jahre Viking was sent by its new owner, Fred. Olsen Production a.s (FOP), wholly owned subsidiary of First Olsen Tankers, to the shipyard Dubai Dry-docks to be refitted as a floating storage and offloading unit ("FSO")

There, it was given its current name, Knock Nevis. The ship now operates as an FSO at the Al Shaheen oilfield in the waters of Qatar.
