"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
French shipbuilder OCEA today launched the first of twenty "OCEA FPB 98 MKI" patrol boats for the State Border Guard service of Ukraine at its shipyard in Les Sables d'Olonne. ===================== In November 2019, an intergovernmental agreement between France and Ukraine has been signed to support the reinforcement of the maritime safety and security in Ukraine. OCEA won the international consultation launched by the Ukrainian Ministry of Interior. The acquisition contract is for 20...
