Wind Impact on Ships Turning Motion


published on 20 January 2021 444 -

Found on YouTube. Created by "ISSIMS GmbH & Institute: Innovative Simulation".
This video complements the earlier demonstration of wind effect on straight track and shows now wind effect on turning circles. It can be seen that during a turn under strong wind the ship reduces turning when it comes close to equilibrium on straight track - if the Wind-to-ship speed ratio is big enough then the ship even goes straight instead of turning. This is shown for three samples for Head, Stern wind and Beam wind. The turning can be increased if the ratio of Wind speed-to-ship speed is decreased by speeding up or when the rudder effectiveness is increased by using kick turns by kicking both engines ahead or at least one by splitting the engines.
