DREVIN BEREEDERUNGS GMBH & CO. K.G.

The company website’s flag is red with a thin white border and a white diamond bearing a black D. The funnel follows a starboard photograph of Maike D dated 2 June 2009.

Thetis D has a darker buff funnel than D552. Because the funnel is to port, its port-side logo sits on a white base equivalent to the superstructure; to starboard the logo is on the main superstructure. Both are attached white panels, so the flag’s white border merges into the background and the field appears plain red.

The two company-named vessels are assumed to show Drevin’s own markings, although they too may have been chartered. Other fleet vessels were chartered out, one visibly in APL colours.
