Ship history

2010: The ship investment company Blue Ship Invest, a part of Ulstein Group, ordered two medium-sized platform supply vessels of the PX121 design, based on trends in the North Sea market.
2012: A continued positive market trend combined with very positive feedback on the first vessel, ‘Blue Fighter’, after some months in operation, led Blue Ship Invest to contract another four vessels of the same design. ‘Blue Power’ is the first of these.
2013: Named at Ulstein Verft by lady sponsor Siw Ulstein. Delivered on 6 March 2013. All six vessels were acquired by Nordic American Offshore on 1 November 2013, and all vessels changed names. ‘Blue Power’ was renamed ‘NAO Power’, IMO 9651890.

When ‘Blue Power’ reported the fuel consumption for a transit mission to their charterer, the reply was that the numbers must be wrong. The consumption was simply too low.

“Our charterer reported back to us that it’s not possible to be that fuel efficient, compared to similar ships,” says Edvard Dahlén, captain on this transit. “We made eight knots and consumed less than 200 litres per hour, which is extremely little.”
“This vessel is set up with two different engine sizes. On this occasion, only the smallest engine was in use. This was a rare opportunity in which we were allowed to keep the speed down to eight knots, and we decided to test how little fuel she is able to use in transit,” says Dahlén.
“The diesel electric propulsion system on this vessel is an ULSTEIN POWER™ delivery developed by Ulstein in close cooperation with Inge-team. The focus on optimised combinations of generator sets and electrical drive units have generated a series of very fuel efficient systems,” comments Gunnar H. Hide, managing director in Ulstein Power & Control.

2015: Two more vessels of the same design, the 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.
