Model Applications

To optimise a port and/or waterway system, operations have to be analysed, a process which is often facilitated by applying simulation models. Simulation techniques have to be used when it is no longer possible to create a simple system.


The model harboursim covers the wet infrastructure op a port and approach channel to the port. The model simulates the vessel movements in these areas. with minor adaptions nearly each port in the world can be represented. Because of the modular structure of this model it is possible to insert detailed models of terminals. Left a possible example application of a Harboursim model and at the right a possible configuration of harboursim model is presented.

Application Maasvlakte II

With the help of the model harboursim a capacity analysis was made in a recent graduation thesis concerning the future Maasvlakte II. A scheme of the harboursim model as used can be seen in the figure on the left. Whereas results of the studies are given in the graph at the right of this text.


The model can be used for many bulk terminals. The model covers all activities on the terminal and because of the flexible structure many types of terminals (ore, coal, grain, oil) in many configurations can be simulated. Moreover it is possible to insert this in the model Harboursim.


The model locksim is used to analyse the functioning of a single lock or a lock complex and describes the ship movement from one side of the lock to the other side. The ship traffic may be subjected to environmental and tidal conditions as well as traffic rules.


The model Shiprisk is a generic tool fot the estimation of nautical risks in harbour approaches or harbour basins. To assign nautical risks the number of encounters per year are converted to number of collisions using statistics of collision frequencies.
