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.

2015: Blue Storm and Blue Viking were acquired by Nordic American Offshore (NAO) on 26 January 2015.

2019: Nordic American Offshore changed name to Hermitage Offshore Services Ltd, which became effective on June 4, 2019. All the vessels will change name to "Hermit" prefix.

2020: All vessels in the Hermitage Offshore fleet have been acquired by Pearl Bidco AS, a company owned by DNB and SEB.
