Ship history

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).

'Blue Prosper' was contracted in 2010 and delivered to BSI on 6 September 2012. Named at Ulstein Verft by lady sponsor Ingerid Ulstein.

Ulstein’s decision to focus on this ship type resulted from careful market analysis. The vessels have an optimum combination of fuel efficiency and deadweight, and a capacity and performance that approaches those of larger PSVs. They can take on most of the tasks usually handled by slightly larger PSVs but at a lower operating cost.

2013: The first six vessels were acquired by Nordic American Offshore (NAO) on 1 November 2013. Blue Prosper was renamed NAO Prosper.
2015: Two more vessels of the same design, Blue Storm and Blue Viking were acquired by Nordic American Offshore (NAO) on 26 January 2015.
2015-2016: The final two of the ten vessels, Blue Queen and Blue King, were delivered to Blue Ship Invest.
2019: Nordic American Offshore changed its name to Hermitage Offshore Services Ltd, which became effective on June 4, 2019. All the vessels changed their names to "Hermit" prefix.
2020: All vessels in the Hermitage Offshore fleet were acquired by Pearl Bidco AS, a company owned by DNB and SEB.
2021: Hermit Prosper (now: ESVAGT HEIDI) was acquired by ESVAGT, and has been converted to an Emergency Response Rescue Vessel (ERRV) at Ulstein Verft and prepared for battery power by Ulstein Power & Control.
