KNUTSEN O.A.S. SHIPPING A/S.

K309 was the original livery, replaced by K227 in 1912. The latter flag is white with a large, plain black K.

The funnel changed to K53 in 1929. Photographs confirm bands separated by their own width, while Talbot-Booth leaves a wider gap. Stewart 1963 joins the K’s angled arms directly to its vertical and shows K53 and K54 as alternatives; it specifies silver or aluminium for K54.

The new flag probably dates to the 1984 change of owners, with the funnel basis unchanged. Brown’s K20 panel makes the lowest blue lines progressively wider downwards, reversing the website logo’s order.

Anna Knutsen’s port side and Kristin Knutsen’s starboard side confirm the K229 funnel. Its flag is Rosanoski’s adaptation of the website logo, made rectangular rather than square in line with Brown, but with the lower bands narrowing downwards.

Ivan Sache’s website-logo image K228 was later removed from FOTW and replaced by K20.

K310 and its alternative K311 were adopted in 1982 according to Skipet.
