"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
Operators and supervisors of the operations center (atalaia) of Praticagem da Barra do Rio Grande participated in an update course in online and face-to-face mode. They had classes on nautical charts, electronic charts (ECDIS), radars, portable pilot units (portable electronic navigation equipment) and technical English. "There is no good operation without recurrent training with good tools", says pilotage operational director, practical Bernardo Ramos
I have had the privilege of being at quite a number of meetings, conferences and seminars, sometimes representing The Netherlands, but mostly representing the Netherlands pilots. I have had many discussions about the role of pilots and pilot organisations, which lead me to write an article “What is the added value of pilotage?”, published in the February 2020 issue of Seaways.
