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

A pilot boat is a specialized vessel that is used to transport pilots to and from ships that are entering or leaving port. Pilot boats are typically small, fast vessels that are designed to operate in a variety of weather conditions and sea states.

With the increasing accuracy and reliability of navigational receivers, this part of the video module will try to establish a better understanding of the mathematical definition of the Earth’s surface and mapping of this curved shape onto a plane surface.

The International Maritime Organization’s (IMO) upcoming amendments to SOLAS Chapter V, Regulation 23, represent a significant step forward in enhancing the safety of pilot ladder operations.

"A performance assessment tool for maritime pilotage operations" - by Jørgen Ernstsen, Norway
When the ship is approaching or leaving a port, a local navigational expert, the pilot, is often provided for assisting the bridge team to safely and efficiently navigate the littoral waters.

Stabilisers are used to reduce the amount of roll experienced by large ships.
In this video, we look at a few different stabilisation techniques. We investigate how different methods work and how successful they are at reducing a roll.

Port Phillip Sea Pilots now have their new website online. The result is impressive. Well done!

Fremantle Ports in Western Australia has awarded local boatbuilder Dongara Marine a contract for the construction of two new pilot boats.
