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 Bollard Pull value, which can be interpreted as the maximum thrust that is developed for a specific amount of time by the propulsion systems of any vessel to the fullest , when it has zero speed in the forward direction, is the criterion that allows us to understand how suitable a tugboat is for a port maneuver or a towing operation.

What is causing the forward motion of a stopped vessel using continous bow thruster action?

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...

Shipping has evolved significantly over the years. Research in maritime safety and operations over the past few decades has been intensive and has resulted in significant improvements.

Northern Ireland-headquartered Artemis Technologies reports that Noatum Maritime, part of AD Ports Group, is to purchase a state-of-the-art 100% electric Artemis EF-12 foiling pilot boat to operate in the United Arab Emirates.

This is a video about a ship berthing in Durban, a beautiful city in South Africa. I made a musical timelapse and wanted to share this with you.
Hope you enjoy the video and please do leave feedback, and also like, share & subscribe.
The music used in the video is - 'Dreams Pt. II by Lost Sky'
