Electrically powered ferry propulsion power estimation in underpowered operational conditions
In 2014 authors performed short engineering analysis of small electrically propelled inland passenger ships. Operational experience gave evidence that in certain weather conditions the phenomena of added aerodynamic resistance may have serious influence on ship speed and manoevurability. Existing regulations do not provide any requirements or guidelines on prediction of air or hydrodynamic resistance or propulsion power in design process. The case is important when electrical or hybrid propulsion is prime mover. The presentation describes results of for engineering analysis of ship design to verify the influence of aerodynamic resistance on propulsion system power selection and performance.
