Pull-Out-Test-Manoeuvre for fast Identification of Yaw Stability – and Lyster-Diagram


published on 14 January 2022 -  156 -

Found on YouTube. Created by "ISSIMS - Innovative Ship Simulation". Originally published on 2021-09-28.
This video shows an introduction on the Pull-out Test-Manoeuvre and describes the procedure how to steer through this simple manoeuvre: Turning circle and then put the rudder amidships. The final rate of turn allows to identify stable and unstable conditions. Samples of stable and unstable ships will be shown by Fast Time Simulation using the SAMMON Planning tool. The role of the rudder angle of neutral effect are explained together with a comparison of Spiral test and Pull-out manoeuvres – and also for the so called “Lystergram”. The difference in stability for ahead and astern motion is demonstrated for a tanker in ballast condition.
Finally, a funny discussion of my experience in a rowing boat with my family will boost your imagination and completes the overview on effects of Yawing stability.
The next videos to follow will demonstrate other manoeuvres (Zig-Zag Test) which are also helpful to identify and discuss the yaw stability for ships.

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 Characteristic Diagrams for ship behaviour under Wind Impact

published on 12 April 2021

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.
