Video Genesis – Berkeley Class Pilot Boat by Dongara Marine
published on 25 October 2020
Harbour Services Australia was the client for this ultra-efficient pilot vessel, Dongara Marine's second Berkeley Class pilot boat to operate from the port of Fremantle. Delivered in June 2019 it joined Fremantle Pilots’ Berkeley, which had already been operating with great success in the Western Australian port since 2015. Purpose-designed to maximise overall operability and the safety and comfort of pilots and crew even in demanding sea conditions, the Berkeley Class provides: • High open...

Video Angostura Inglesa ("English Narrows")

2 48° South 074° West
"Angostura Inglesa" is, without a doubt, the most important natural obstacle in navigating the South American channels, as it is a winding step that requires two changes of course close to 90 °, subject to a tidal regime and Considerable currents, which is also affected by the frequent bad times of the Gulf of Penas, forces sailors to face it with caution and take adequate security measures.
Video Wind Impact on Ships Turning Motion
published on 20 January 2021
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...

Video Operation of POD Ships - Discussion on Efficiency comparing Conventional and IN-OUT POD strategy
published on 8 June 2022
In this movie the efficiency of two different pod operation strategies is compared: With azimuth propeller ships the Pods can be used in two ways to control the speed, e.g. for speed reduction: 1. by adjusting the engine orders, e.g. by reducing the RPMs to get lower speed - this means to drive the ship in the same conventional way as for twin screw vessels, 2. by turning both pods either in- or outward (TOE-IN or TOE-OUT) to reduce the forward thrust and therefore reducing the speed – the...
