Ship history

Originally named 'Blue Viking'. Delivered to Blue Ship Invest on 19 January 2015, and further to Nordic American Offshore (NAO) on 26 January 2015, together with a sister vessel, 'Blue Storm.'

The vessel was number 8 in NAO’s fleet of PX121 designs, as NAO acquired six vessels of the same design in 2013. The vessel is quite similar to the six previous vessels, apart from its adaptation to the Norwegian Maritime Authority’s emergency manual NMD rescue (200), and alterations to satisfy requirements for oil recovery, minor outfitting changes and the installation of a larger crane. At the delivery of the two vessels, NAO announced that the prefix of all their vessels will change from ‘Blue’ to ‘NAO’.
