Hello!
Yes, you can find examples of models related to marine transport in our demo models. Particulary, you can look at:
1. "Canal and Lock" model at http://www.xjtek.com/anylogic/demo_models/traffic/, and
2. "Tanker unloading" model at http://www.xjtek.com/anylogic/demo_models/logistics/.
Generally, AnyLogic allows for creation of all types of transportation models. You can easily animate your models,
collect and represent all requred statistics. Moreover, AnyLogic is an extendable modeling platform: you can implement
robust algorithms on Java language, plug in your own modules.
