Characteristic Diagrams for ship behaviour under Wind Impact


published on 12 April 2021 354 -

Found on YouTube. Created by "ISSIMS - Innovative Ship Simulation". Originally published on 2020-12-25.
This movie shows how to create the Characteristic Diagram for Wind effect on ships and limits of steerability under strong wind. It uses the previous demos made with the SAMMON Planning Software on turning tendency of ships on straight track and in turning motion. It reveals insight on the regions of windward and leeward turning tendency using these diagram as well as for the importance of wind-to-ship speed ratio on the limits of steerability in certain regions of wind encounter angle to the ships course.
Please enjoy!

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...

Video Safe at sea with satellites (AIS)

published on 5 June 2020

At sea, space technology is used to help save lives every day: managing traffic between ships, picking up migrants and refugees in distress or spotting oil spills. The European Space Agency is once again at the forefront developing new technologies and satellites: to keep us safe at sea and to monitor the environment. Space makes a difference here on Earth and certainly at sea where there is no infrastructure.

Video Wind Impact on Ships Turning Motion

published on 20 January 2021

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...

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.
