Simplified Vector Approach for POD forces – samples and limitations


published on 23 February 2022 306 -

Found on YouTube. Created by "ISSIMS - Innovative Ship Simulation". Originally published on 2022-02-16.
This movie belongs to the operation of ships with POD propellers and discusses the approach for using a vector model from only the pods’ thrust forces as resulting force to imagine the potential effect of the pods on manoeuvring motion. This simplification neglects the effect of e.g. of propeller interference to the ship structure and the other pods as well as the rudder effect of the pod structure even with no thrust in passive mode. Numerous samples of manoeuvres with one or two pods in typical IN-OUT or TOE-IN configurations will be demonstrated with the SAMMON planning tool to show where the simplified approach is working or other effects need to be considered additionally.
