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.
