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...
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.
The technology group Wärtsilä has delivered a navigation simulator and specific mathematical models to the Satakunta University of Applied Sciences (SAMK) in the city of Rauma, Finland. These will be used as an essential enabler in the Intelligent Shipping Technology Test Laboratory (ISTLAB) project, which aims at creating a technically precise testing environment for remotely controlled, autonomous vessels. The contract with Wärtsilä was signed in the 4th quarter of 2019.
