Design

The vessels are of the Vik-Sandvik design VS 794 CGV, and were built by Myklebust Verft and operated by Remøy Management on behalf of the Norwegian Coast Guard.

The Coast Guard expects a 90% decrease in NOx fume releases, and a 20% decrease in CO2 releases compared to a conventionally powered vessel of similar size.

The ships are set to replace NoCGV Chieftain, Tromsø and Stålbas. Chieftain's lease contract expired at the end of 2007, Tromsø's contract expired on the 20 March 2007, whereas Stålbas' contract expired at the end of 2006. NoCGV Barentshav was delivered in August 2009, and was followed by Bergen and Sortland in late 2009/early 2010 and 2010.

The Barentshav class is equipped for the NATO Submarine Rescue System.
