The simulations were carried out with a 1700 TEU vessel for which the mathematical manoeuvring models had been derived from a comprehensive captive model test program (cooperation FHR and Ghent University, 2001-2004). During this experimental program the ship behaviour above and in contact with several mud layers had been investigated.
The simulator study revealed the possibility to work with a nautical bottom which is at a lower level than the top of the mud layer. This opens up the possibility for the port of Delfzijl to receive vessels with a larger draft in the future without the requirement of extra dredging efforts. In order to validate the conclusions from the simulator study, full scale testing of ship manoeuvring was performed on a general cargo vessel sailing outbound from the harbour of Delfzijl. These full scale measurements reveal the influence of a mud layer on the manoeuvring characteristics of the vessel.
The paper gives a detailed introduction to the examined problem, a summary of the model test setup, simulator study and full scale testing.
