Hammonia Reederei GmbH & Co. K.G.

A white flag has vertical black stripes at the hoist and fly edges. Above centre is an unoutlined shield-like logo: three red rectangular Hamburg towers, the outer two topped by red six-pointed stars, over a blue field separated by a white wavy line. Beneath it, black serif capitals read HAMMONIA over the slightly smaller REEDEREI.

Hammonia was established in 2003 by Döhle and HCI, with General Electric joining later. It managed containerships for closed-end funds and the fleets of HCI Hammonia Shipping and Capitalships. It shared the Hamburg location with Döhle and Hellespont; Döhle maintained its management.
