When facing a manoeuvring test, it is not uncommon that the first topic you come across is precisely the evolutionary effects of the propellers. To better understand this aspect, it is necessary to briefly mention the different characteristics between fix-pitch and variable-pitch propellers and then - with some examples - fix this information with the reasoning developed to haul a ship to the quay. But that's not enough, because there are many other aspects to consider.
Do you know the acting forces in the swinging or the Paddle-wheel effect of the propellers? Why Coanda effect occur? The Azipods and their use in manoeuvring?
In addition to these topics, we will also talk about Pivot Point, Cavitation, the various propulsion systems, etc. Upon completing this course, the candidate will understand the characteristics of the types of propulsion and their use in manoeuvring.
The learning outcomes of the course will include:
1 Propeller pitch
2 Turning effects of the propeller
4 Practical manoeuvre
5 Pivot point
6 Bow thruster
7 Turning with a twin-propeller
8 Types of propellers
9 Let's take off the rudder!
10 Manoeuvring an azimuth
11 ACD Azimuth Controlled Device
12 Manoeuvring the azipods - ACD
13 Pressure of the wake
14 Practical consideration
