| Abstract |
The manoeuvring behaviour of vessels is significantly affected by restrictions of the navigation areas. Especially the clearance between the keel and the bottom of the seabed is important. Additional difficulties arise when this bottom is covered with a fluid mud layer. Most vessels are designed to navigate in deep water areas, although for simulation purposes pilots should be able to train with realistic mathematical models in confined areas. A mathematical ship manoeuvring model has been developed taking the under keel clearance and the bottom characteristics into account. Thanks to this mathematical model and simulation runs a redefinition of the nautical bottom in the harbour of Zeebrugge was possible, resulting in the acceptance of larger vessels or a reduction of maintenance dredging. |
