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

From "Casual Navigation": In this video, we investigate the Pilot Ladder. It is a crucial piece of equipment, used for embarking and disembarking a harbor pilot at sea.(contains advertising)

The Arctic magnetic pole does not move anymore. It runs, faster and faster. In recent years, even faster than expected. Therefore, geo-researchers have now had an unscheduled change to their world model and adjust their calculations, so that navigation with compass and other navigation aids such as a Pilot Plug, used by pilots around the world, continue to work.

This movie belongs to the operation of ships with POD propellers and discusses the approach for using a vector model from only the pods’ thrust forces as resulting force to imagine the potential effect of the pods on manoeuvring motion.

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.

Here's a cool little video of 'PORT LÁIRGE', the Port of Waterford’s new pilot boat we've just launched and it was wonderful to have built another pilot boat for Ireland. She's our 15m Interceptor 48 pilot and is the 48th pilot boat we’ve supplied to ports globally. Powered by a pair of Scania D13 500hp engines she has an operational speed of over 25kts and is capable of carrying of 5 pilots and 2 crew in fine comfort. I think she looks just fabulous in red and blue and look forward to...
