Education: Effect of Drift Force and unstable moment

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!

This video is an extract of some elements from lectures by Knud Benedict on "Simulation" as part of the seminars provided by the IALA World Wide Academy on the use of the "IALA Toolbox for Port & Waterway Risk Management".

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 world of hydrography is going digital and the S-100 standard is an essential component of that move.” See how the Canadian Hydrographic Service has led Canada to become one of the first countries in the world to start using the S-100 standard, and how implementing these standards will benefit Canadians through increased safe navigation in Canadian waters.

This article was first published back in September 2021: Pilotage operations require close interaction between human and machines. This complex sociotechnical system is necessary to safely and efficiently maneuver a vessel in constrained waters.

Ships have reported an increasing number of cases of significant GPS interference and jamming in recent months. The geographic areas with more than one reported incident include the eastern and central Mediterranean Sea, the Persian Gulf, and multiple Chinese ports.

Why loud and clear communication is very important.

SWATH and SWASH are interesting technologies that allow a vessel to sail much more calmly in high waves. A stable and calm position of the ship is especially important for pilot boarding.

Compulsory pilotage will now be required for dry cargo and passenger vessels over 3,000 gross tonnes and tankers of 1,000 gross tonnes transiting eastern Hong Kong waters to and from the area of Yantian Container Terminals and Dapeng LNG Terminals, according to a Hong Kong Government Ordinance.
