On the one hand, the size of the double-hulled ships is most important ; They are (2010) among the largest container ships in the world. In terms of shipbuilding, however, there are a number of innovations and details that are more conspicuous, especially in terms of environmental protection in maritime shipping . In contrast to the majority of conventional container ships, the deckhouse is arranged far forward, which enables an improved line of sight and thus higher forward deck loading. Among other things, the bunker tanks are arranged below the superstructure in order to meet the latest MARPOL regulations. The powerful drive system with the two-stroke diesel main engine type MAN B&W 12K98MC-C positioned as far aft as possible is also outstanding. The holds of the ships are closed with pontoon hatch covers. The ships have a maximum container capacity of 13,800 TEU, with an average container weight of fourteen tons, the capacity drops to around 10,640 units. There are also 1000 connections for integral refrigerated containers , of which up to 900 can continue to be operated during maneuvers.
