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). These have later been sold to various ship owners.

2013: 'Blue Guardian' was named at Ulstein Verft by lady sponsor Elsa Kleppe. Delivered to BSI on Friday 28 June 2013. The ship started work in the spot market, and two weeks after delivery, the vessel entered into a 4-month contract with Statoil (now: Equinor), with 4 monthly options. The contract involved being a support vessel for the jack-up rig Maersk Giant in its work on two subsea wells, owned by Det Norske Oljeselskap ASA and Repsol Exploration respectively, on the Norwegian continental shelf in the North Sea.
 

These latest vessels in the series have been adapted to requirements for work in the Norwegian sector. That includes more power in order to keep position in foul weather at rig, and NOx reduction for the exhaust emissions. In addition, they carry the light ice-class (ICE-C), to be prepared for work further north.

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.
