Stricter regulations on emissions force ship owners and designers to come up with new solutions for ship propulsion systems. Hybrid drive systems consisting of prime movers and batteries, like in the Toyota Prius, show great potential, especially in special ships like harbour tugs. Economic and environmental performance of such systems strongly depends on the way it is controlled. Dynamic computer models of system components were built to compare different system lay-outs and different control strategies and thus support the ship system designer with design decisions. A combination of fuzzy rule-based and optimization-algorithm control offer the best results. The modeling method, the different simulations, the optimization methods and resulting consequences for the ship system design are the main topics of this paper.

Environment-friendly inland shipping
Dynamic modeling of propulsion systems for inland ships using different fuels and fuel cells
To meet possible future emission regulations for inland ships alternative propulsion systems with fuel cell technology and batteries are researched. A rather simple, yet efficient dynamic model is being developed to simulate four different propulsion system configurations with different fuel cells and different fuels. The system configurations and sub models are discussed in this paper, as well as the design considerations and lay-out of the energy control system and results of the first simulations.
