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

In fact, the pivot point that we “see” is a trick of the eye, it looks like the ship is rotating about this point but in fact it is elsewhere, a point that you cannot see.

The term Automatic Identification System (AIS) refers to a radio system that improves the safety and guidance of vessel traffic by exchanging navigation and other vessel data.

When the bow thruster has been in operation for a while, pilots often notice that the ship not only turns but also gains speed. But why is this? Opinion by Capt. Hugues Cauvier.

The Seminar aims to inform Member States, intergovernmental organizations and non-governmental organizations in consultative status with IMO about the societal value of maritime pilots and pilotage as a public service. The IMO Secretary-General has recognised maritime pilots as having always been vital to ensuring the safety of navigation in key ports and shipping lanes globally and playing a crucial role in sustaining the global supply chain using specialized knowledge and expertise....

At Humber Maritime College we have state-of-the-art marine simulators to teach our Merchant Navy cadets in an environment close to reality, preparing them for a career at sea.

The #ESAIL #microsatellite for tracking ships worldwide was launched. This is the first maritime satellite of its kind produced and assembled in Luxembourg. Hear from #Luxembourg Minister of the Economy Franz Fayot about this pioneering #ESA partnership project developed with #LuxSpace and #Exactearth.

The pilot boat Lesath brings the harbor pilot to the Allegro. It was windy and the sea was rough, the conditions where not extremely, but the boarding is not whitout risk.
This video is created 2 days after storm Ciara in the Port of Rotterdam. This was also the first day that the containerterminals where open after the storm.
Shipspotting Rotterdam,
