Found on YouTube. Created by "ISSIMS - Innovative Ship Simulation". Originally published on 2021-01-29.

This movie reveals some practical insight into regions of course stable / unstable conditions under wind. And I dare to say you can get some insight into other stability types and analogies, too!
The details are:
- Introduction of stability - using a lemon in a kitchen bowl
- comparison with cargo / cross stability / yaw stability
- Definition of course stability under wind
- Regions of stability and the relation with positive or negative slope on characteristic wind curves for rudder.
Respective samples will be given for ships behaviour in stable (e.g. beam wind ) and unstable (e.g. head & stern wind) conditions. And conclusions will be drawn from ship stability up to our Earth...
I hope you enjoy and give your thumbs up or even to follow this ISSIMS Youtube channel!

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 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...
