Extreme conditions drilling firm North Atlantic Drilling is to launch a $600million bond offer.
The Seadrill-owned firm, which has been looking at an initial public offering to enter the New York Stock Exchange, said it was looking to offer unsecured notes in a private offering.
The offer, the firm said, would be used to pay down existing debts and early settlements.
Last year the John Fredriksen-owned drilling giant put talks to sell off its stake in North Atlantic on hold, having previous been in discussions about selling off a stake in the firm to an unnamed partner.
