A computer-based system for simulation of ship steering and ship traffic in restricted waters is presented. The system is making use of a general purpose, interactive computer facility for simulation of dynamic processes (GENSIM), comprising both a hardware system, including four color TV-screens, trackerball, keyboards and a console for process control and supervision, and an associated software package (SUPERSIM). The Main Modules of MANSIM: The SHIP module describes the dynamics of the ships using differential-, logic-, and algebraic equations. The ENVIRONMENT module describes the environmental factors and comprises topological description of the area under consideration. The OPERATE module allows the operator to interact with the system. By use of predefined push buttons, the operator controls the SHIP module. Particulars of the Simulator System: Ships may be manoeuvred/steered on the TV-screens under the influence of the environment (current, wind, bottom, etc.). Ship traffic operation/transportation analysis may be performed in both a deterministic and random way. The Main Objectives for such Simulations: To analyse ship manoeuvrability. To analyse a ship's ability to navigate a given fairway and to determine the risk by that navigation. To analyse ship accidents with respect to manoeuvring possibilities and limitations. To determine procedures which will minimise the risk of accidents during navigation in a given area.
