Ns345 W6D2 Ship Interactions and Bank Effects

Drydocking or undocking is always a difficult task, particularly with a “dead” vessel (no power/propulsion) and the wind blowing on the ship's side.

Currently, several means of transport are undergoing an accelerated development towards automation and automated movements. This development will also impact future ship handling with tugs. A glimpse into the future of tug boat operation.

This video explores the question of why ships are so difficult to manoeuvre in reverse.

This video complements the earlier demonstration of wind effect on straight track and shows now wind effect on turning circles. It can be seen that during a turn under strong wind the ship reduces turning when it comes close to equilibrium on straight track - if the Wind-to-ship speed ratio is big enough then the ship even goes straight instead of turning. This is shown for three samples for Head, Stern wind and Beam wind. The turning can be increased if the ratio of Wind speed-to-ship...

This video has been recut and edited by the creator Hugues Cauvier. Previously there were three episodes, which have now been combined into one.

Understanding the fundamentals of the pivot point is highly required for understanding the alteration of the courses. Pivot point is an imaginary point on the vessel which turns on a circular path on the perimeter of vessel’s turning circle when the vessel makes a turn. The knowledge about the position of the pivot point in a manoeuvring situation provides the ship handler with the information on the geometry of motion of the ship.
