Herbjorn Hansson-chaired Nordic American Offshore (NAO) has won a 20-month extension on waivers to its main credit facility.

NAO has not announced the extension, but it is disclosed in its most recent annual report filed with US securities regulators.

The company, a spin-off of Hansson’s Nordic American Tankers (NAT), originally negotiated a $60m facility with a syndicate of lenders in December 2013.
