On the one hand, the size of the double-hulled ships is most important ; When they were built, they were among the largest container ships in the world. A number of innovations and details are striking in terms of shipbuilding, especially in terms of environmental protection in the shipping industry . 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. In the bow there are two transverse thrusters, each with an output of 2,000 kW. The holds of the ships are closed with pontoon hatch covers. The ships have a maximum container capacity of 12,400 TEU , with an average container weight of fourteen tons, the capacity is reduced. There are also 800 connections for integral refrigerated containers .
