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.

Video How Ship Anchor Works? - Procedure For Anchoring a Ship at Sea

published on 11 July 2020

#Anchor #shipanchor #windlass Anchoring is one of the very frequent operations onboard ships. A number of variables and external factors influence the duration and location of an anchoring operation. While the type of seabed is of utmost importance during anchoring, soft muddy grounds or clay bottoms are best preferred. It should be taken care that the anchoring bottom is free of power lines, submarine cables, pipelines or rocks. Various methods on anchoring include consideration of...

Article Navigation alternative in the event of GNSS failure due to jamming or spoofing

by TRENZ GmbH - published on 7 April 2025

What happens when GNSS fails? In maritime navigation, this isn’t a hypothetical scenario – it’s a growing risk. Spoofing, jamming, and GNSS outages are increasing, especially in the Baltic Sea region. A failure can cripple navigation systems – with potentially serious consequences.

Video Operation of POD Ships - Discussion on Efficiency comparing Conventional and IN-OUT POD strategy

published on 8 June 2022

In this movie the efficiency of two different pod operation strategies is compared: With azimuth propeller ships the Pods can be used in two ways to control the speed, e.g. for speed reduction: 1. by adjusting the engine orders, e.g. by reducing the RPMs to get lower speed - this means to drive the ship in the same conventional way as for twin screw vessels, 2. by turning both pods either in- or outward (TOE-IN or TOE-OUT) to reduce the forward thrust and therefore reducing the speed – the...
