Ship history

The ship investment company Blue Ship Invest, a part of Ulstein Group, ordered ten platform supply vessels of the PX121 design in the period 2010-2014. Eight have been acquired by Nordic American Offshore (NAO).

'Blue Storm' 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 Viking.' The name of the vessel was changed to 'NAO Storm', IMO 9722510.

The vessel is number 7 in NAO’s fleet of PX121 designs, and 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.

Yno 289 NAO FIGHTER - delivered January 19, 2012, original name Blue Fighter.
