For modelling and simulating of marine rudder system, there are lots of along with their model libraries, such as AMEsim could be used. But the models in these tools lack of flexibility and are not open to the end-user. And these tools could not model the whole marine rudder system consisted of mechanical, hydraulic and control sub-system in a unified form. In order to solve those problems, a flexible and extensible marine rudder system library was constructed, based on the Modelica, by the object-oriented strategy. It supports the reuse of knowledge on different granularities: physical phenomenon, component model and system model. A conventional model of marine rudder system was built and calculated using the library, and the results shows that the object-oriented modelling strategy is effective; the framework of the library is reasonable.
