"Effect of Drift Force and unstable moment"
-------------------------------------------------------------
SAMMON - the IDEAL tool to identify manoeuvring capabilities of a ship - SAMMON - learning the EFFECTIVE way
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!
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
This video explains the IMO resolution on the provision and display of maneuvering information on board ships, particularly the pilot card, wheelhouse poster and maneuvering booklet. the layout and contents of each are explained as well. Contents of this video will benefit mariners preparing for exams (written and oral examinations). Mariners will also benefit by watching the following videos: Duties of the SAR mission coordinator: https://youtu.be/9J3q6XczIGE Duties of the on-scene...
