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

These images show a Navigation drill (SIMULATION) of approach and mooring to one of the Harbours of the Paraná River - "TIMBUES" Harbour (Management and Resources of the Navigation Bridge for Pilots) - (BRM - P) in charge of the Paraná Harbours Pilot, Captain Mr. Diego SCHOTTENHEIM. Exercise carried out in the Navigation Bridge Simulator of the Maritime and Riverine Research and Training Canter (MRRTC), Autonomous City of Buenos Aires #Argentine on March 12, 2019, since 14:50 till 15:55...

This video shows an introduction on the Pull-out Test-Manoeuvre and describes the procedure how to steer through this simple manoeuvre: Turning circle and then put the rudder amidships. The final rate of turn allows to identify stable and unstable conditions.

When a vessel navigates in confined waters, such as in a harbour or narrow channel, it is well known among experienced pilots that the ship handling is greatly affected by the hydrodynamic forces and moments acting between ship and bank or sidewall of the channel.

“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.

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.

On the occasion of the Maritime Safety Week (July 4-10), UK MAIB’s inspector Bill Evans refers to the issue of unsafe pilot ladders, a concern that has been regularly voiced by the industry.

Here’s a cool little video of the rough weather sea trails of ‘Port Láirge’ The Port of Waterford’s new Interceptor 48 pilot boat ready to be delivered next week. We had two days of rough weather, a Force 8 with 3.5m seas putting up some surf breakers over the Daunt and a second day with winds reaching Force 10 offshore, with 55kts of wind and 5m swells, allowing us to properly test her capabilities ensuring she's fully fit for purpose for the pilots and crew. Doing so we captured some...
