Vs 794 CGV design
KV Barentshav was built by Myklebust
Verft, part of the Kleven Maritime
group in west Norway, based on hull
steelwork fabricated in Romania to the
VS 794 CGV design. The second vessel
(KV Bergen) is at the shipyard for fitting
out, with delivery scheduled for the end
of this year, while the hull of the third
vessel (KV Sortland) is being fabricated to Kystvakt. The crew is a mix of coast guard of 18, but if needed up to 40 people can
