1. Seminar Buenos Aires, 2004 Port Capacity Versus Port Safety by R. Groenveld

2. Seminar Buenos Aires, 2004 Methodology

3. Seminar Buenos Aires, 2004 Safety and Capacity Studies Manoeuvring simulation study - dimensions wet area and - the accompanying ship traffic rules Traffic flow simulation study - estimation wet infrastructure capacity - number of berths Ship Risk model -determines the number of encounters - and with historical data the number of casualties

8. Seminar Buenos Aires, 2004 Model Harboursim Input: Random arrivals of the different ship types, traffic rules, dwell times, sailing times etc. Simulation: Ship traffic through the port Output: Entrance time and departure time from the terminal, waiting times of the vessels, satisfying: 1. The traffic rules 2. Availability of a berth 3. Tidal conditions 4. Etc

10. Seminar Buenos Aires, 2004 Configuration Traffic Flow Simulation Model

11. Seminar Buenos Aires, 2004 Major Components Shiprisk ComponentTask MainInitialises the model ShipDescribes the process of the ship GeneratorGenerates the individual vessels according to output from the traffic flow simulation model. VTSControls the distances between the vessels EncountersA data component, provides the data of each potential encounter

13. Seminar Buenos Aires, 2004 Number accidents per 10 6 encounters ( registered in the Straight of Dover)

18. Seminar Buenos Aires, 2004 Some conclusions and recommendations  The model 'SHIPRISK' provides a quick insight of the nautical risks  More prototype information should come available with respect to encounter frequencies  More data on vessel behaviour depending on infrastructural conditions, environmental conditions, and traffic loads should be collected for a statistical description of vessels tracks
