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

In the spring of 2023, the IMO Sub-commission on Navigation, Communications and Search and Rescue (NCSR) may start a process of review and amendments to the SOLAS Ch V. reg 23

Wind Balance on straight track - using SAMMON to learn the theory and the effect of rudder and drift to reach the balance in steady state equilibrium conditions on straight track. Limits of steerability will be shown and how turn under strong wind.

A new 1:25 cruise ship manned model, the "Voyager", was added to our fleet in 2014. She is 311 m long and is fitted with 2 azimuthing pods (and one Fixipod) and powerful bow thrusters. Training is conducted in emergency conditions like engine failures, crash stops, tight turns ...

Case Study: An investigation into whether Port of Melbourne and major port user, ExxonMobil, could bring deeper drafted vessels into the channel.

Graham Grant, the Port of Cromarty Firth’s Marine Support Manager, has been appointed to the National Council of the UK Harbour Masters’ Association (UKHMA).

Ich bin zu Besuch beim Lotsbetriebsverein in Bremerhaven und unterhalte mich mit dem Ältermann Jan-Helge Jannsen über das Lotswesen in Deutschland. Wir fahren außerdem mit dem Lotsenboot raus und begleiten Lotsen und die Crew auf den Versetzern bei einem Einsatz.
