DST, ConoShip and Schipco have completed a fleet analysis of inland waterway and shortsea vessels in terms of vessel types, sizes and motorization as well as navigational profiles. This analysis has provided a good overview of the required power output required of the energy pack and also the number of power packs that will potentially be required. Initially a statistical evaluation was done to establish an overview of the number of vessels and their motorisation. Navigational profiles were considered relating to the GMS-type vessel (L x B = 110m x 11.45m) with 1000kW installed power.
