"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
We have successfully implemented and tested our new online engine simulator trainings. Currently we offer four online trainings. - MAN Engines Operation and Analysis (ME) - MAN ME Engine Electrical Course - MAN ME-B Engine Operation and Analysis - MAN ME-B Engine Electrical Course Find more information and current schedules on https://mtc.hamburg/training Music: Better Day by BatchBug | https://soundcloud.com/batchbug Music promoted by https://www.free-stock-music.com Creative Commons...
Required tug power and number of tugs needed in variable conditions of wind, current and waves isin most cases an assessment made by pilots based on their professional experience. However, assessments will raise questions by lawyers if something goes wrong. They will use tools to calculate what really is needed with respect to tug power and number of tugs. They have furthermore the advantage of time.
The first of three Watercat 160 Pilot was delivered to the Finnish Finnpilot Pilotage Ltd. in spring 2022. This PILOT boat has a self-righting ability as well as the ability to sail in surface ice of up to five centimetres thick. It can also be operated in deeper offshore waters to accommodate transfers of pilots to deeper-draught ships. The Watercat 160 Pilot can operate even in more restrictive inner harbour waters. The bow has D-type rubber fendering while the hull sides are equipped...
