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

Through the years, the Dutch Pilots have developed a system of selection, initial education and continual professional training. What is the current state of affairs?

Port operations, whether these are being performed on water or on land, are often not without risk. Pilots boarding a ship while sailing, navigating through narrow passages, collision avoidance with other smaller or larger vessels, discharging and moving cargo on land, walking between container handling equipment and trucks…

The man-overboard manoeuvre includes all measures to rescue a person who has fallen overboard from a watercraft.

When publishing articles or pictures about pilots and their pilot ladders, very often we see the use of backpacks. The use of backpacks is controversial, since its weight, or buoyancy, can influence the functioning of the lifejacket used.

RightShip continues its webinar series on pilot ladder arrangements. On September 18th, they´re asking two marine pilots to share their first-hand perspectives on pilot ladder arrangement best practices.
