Education: Effect of Drift Force and unstable moment

How to get information for wind & current limits to be potentially encountered by thrusters – or current? - this will be described in this movie:
- Measure Drift speed, due to beam wind with no propulsion;
- Measure drift speed using full thrusters
- Estimate wind & current limits to be potentially encountered by thrusters – or current...
- Finally there is a simple formula as Rule of Thumb: the transverse drift speed is about 7-8% of wind speed!

This video is an extract of some elements from lectures by Knud Benedict on "Simulation" as part of the seminars provided by the IALA World Wide Academy on the use of the "IALA Toolbox for Port & Waterway Risk Management".

Another very good explanatory video by Knud Benedict. Absolutely worth seeing.
Yaw Stability is an important element of Ships Manoeuvrability - both for course keeping and turning ability. This first video in a series explains the Basic Principles of stability in steady state equilibrium conditions and the forces / moments involved

Before you, you see my third article on pilot boarding arrangements. After my two previous articles ‘1000 ways to secure a pilot ladder’ and ‘1000 ladders around’, I have received a lot of feedback and also questions to get deeper into the matter of combinations and embarkation platforms.

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.

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...

The #ESAIL #microsatellite for tracking ships worldwide was launched. This is the first maritime satellite of its kind produced and assembled in Luxembourg. Hear from #Luxembourg Minister of the Economy Franz Fayot about this pioneering #ESA partnership project developed with #LuxSpace and #Exactearth.
