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 were acquired by Nordic American Offshore (NAO).

'Blue Fighter' was contracted in 2010, and delivered to BSI on 19 January 2012. She was named at Ulstein Verft by lady sponsor Kathrine Gåsvik Ulstein. After only days of operation in the spot market, ‘Blue Fighter’ entered a one-year contract, with an option for an additional year, with the American oil company Apache for work in the North Sea.

Remøy Shipping has technical and commercial management of the vessel. The vessel's first Captain, Inge Gjelsten, had mastered several newbuilds before, but stated that:

"A vessel of this type is my preferred choice for the North Sea. It is remarkably efficient and comfortable in all weather conditions. Wind and seas have little impact on the vessel’s performance compared to conventional PSVs. We can compare performance directly when steaming on the same tracks to the oil fields: With the same weather conditions and 3-5 metres head sea within 30 degrees of the bow, our ship can easily and comfortably maintain a speed of 12-13 knots, while the other vessels have to reduce their speed to 7-8 knots. The higher speed is a result of the ‘X-BOW® effect’. Also, due to the position of the stabilisation tanks on board, ‘Blue Fighter’ operates extremely well when wind and seas approach from the side.”

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.

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.
