Spesial features

AF Decom AS is awarded the contract of striping down and removing the parts from the battleship ”Murmansk” which went shipwrecked in the costal cone outside the village of Sørvær in Finnmark in 1994. The ship which is 211m long with deadweight of 17.000 tons had a crew of 1.800 sailors.
