"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
The need to hold such a webinar was felt from the interaction over several months of AIMPA members through its President, Capt. Gajanan Karanjikar, with Capt Simon Meyjes and Capt.Ravi Nijjer - both instrumental in the thorough upgrade of pilotage operations Safety management systems in parts of Australia. From these interactions, AIMPA has come to the firm conclusion that a thorough upgrade of maritime pilotage management systems in India is necessary. Holding a webinar would be a good...
