A.K. AAGESEN & PARTNERS A/S.

A612 is based on a port-side photograph of Tarco Sea dated 4 April 2007. The logo appears slightly angled until judged against a line level with the bottom of the black funnel top. The same markings remained in 2009 and are confirmed in a starboard photograph dated 15 March 2011. Viscaria also carried them, as confirmed on 22 April 2008.

A photographer suggested that “PS” stood for Partner Shipping. Rosanoski considered this reasonable but did not accept it as proven: use of the markings under the earlier Tarconord ownership would undermine the explanation. He also treated the idea that the diamond’s four corners signified “Four” as speculative. Because both ships retained their markings through registered-owner changes, he attributed the livery to A.K. Aagesen & Partners as their apparent ultimate owner.
