| Abstract |
In 2011 captive manoeuvring tests have been carried out with a 1/25 scale model of an estuary vessel in the towing tank for manoeuvres in shallow water (co-operation Flanders Hydraulics Research – Ghent University). As this vessel was equipped with two contra-rotating Z-drives, a significant part of the testing program focussed on the propulsion and steering behaviour of this system, by repeating tests at different azimuth angles and propeller rates. These tests enabled the assessment of the interaction behaviour between the two drives and their effect on the propulsion and steering behaviour of the ship. In this way a mathematical model could be developed for implementation in a full mission inland ship manoeuvring simulator. The paper intends to give a description of the testsetup followed by an extensive discussion of the effect the Z-drives on the manoeuvring behaviour of the estuary vessel. |
