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

Thanks to Jacqui Kenyon, Chevi King and Kate Delisky for joining Jeanine Drummond on this webinar to discuss their careers and pathways into marine pilotage. The audience was a great mix of experienced marine pilots and newer maritime industry participants, as well as school aged children, with people joining us from Australia and overseas. It was an opportunity to create greater awareness of the maritime industry, and the important role marine pilotage plays in protecting our port...

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.

Footage showing what the simulators look like and how they can be used to simulate ship movement in various ports.

In early December, just as I was starting to get into ship spotting, I saw a couple of vessels headed up river towards Philly. One of them, the Cielo di Iyo met with the harbor pilot right as I had my drone up. I was able to capture the Pilot coming to meet the vessel and CLIMBING the ladder to get on board just before she passed beneath the Walt Whitman Bridge.

Impatience is triggered when we have a set goal (for example berthing a vessel) but realise it's going to cost us more than we thought to reach it (the vessel is only making 6 knots against the tide and is taking much longer than predicted).
