Norway's Olympic Subsea has finalised a NOK 2.9bn ($335m) long-term debt restructuring that leaves it free to move on to its planned Oslo initial public offering.

The company said a majority of banks have been brought on board for a deal that clears maturities to 31 March 2023.

Interest repayments will be lower, the cash balance will be "sufficient" and financial flexibility will be improved, Olympic added.
