In September 2018 Transocean acquired Ocean Rig UDW for $2.9 billion. About 6 months later, the sister vessel Eirik Raude being stacked for 2 years was offered for scrap.
As for the Leiv Eiriksson, the semi’s final gig was a profitable one. It was contracted by ConocoPhillips to drill on the Norwegian Continental Shelf, serving to the US large strike massive fuel condensate and oil discoveries in November and December 2020, respectively.
