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 NO_x fume releases, and a 20% decrease in CO₂ releases compared to a conventionally powered vessel of similar size.

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

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