Traditions broken in modern container ship design

The design of a say 5 year 'young' container ship is usually the result of an optimisation for maximum speed at design draught. Such design is mostly the result of an attempt to reach the contractual speed. However, a well balanced modern container ship should be a compromise between minimum fuel consumption and maximum cargo capacity across an intended or forecasted operational profile. In the design process, the focus should not only be on the calm water resistance and propulsive aspects but also the added resistance due to wind and waves should be considered, as well as the cavitation behaviour and related propeller induced pressure pulses. The SAVER 10000 developed for and in cooperation with the Canadian Owner Seaspan Ship Management Limited (Seaspan) is a pioneer in this new approach to balance the minimum fuel consumption and maximum loadability, taking into account the aspects as indicated.
