The ship investment company Blue Ship Invest (BSI), a part of Ulstein Group, ordered ten platform supply vessels of the PX121 design in the period 2010-2014. Eight were acquired by Nordic American Offshore (NAO). These have later been sold to various ship owners.
'Blue Viking' was delivered to BSI on 19 January 2015, and further to Nordic American Offshore (NAO) on 26 January 2015, together with a sister vessel, 'Blue Storm.' The name of the vessel was changed to 'NAO Viking'.
