Correct preparation of the crew for work can be obtained via long-lasting appren-ticeship at sea, or training at simulators. The simulator of the moving ship in the marine environment is presented. It has an ability to realize different training scenarios and the follow-up action of training in real-time. The simulator makes it possible to test the ship steering systems, to verify the collision avoiding systems, the testing of the autopilot etc.

The article presents a simulator for testing the operation of automatic systems controlling ship's movement in situations where a collision is a real threat, particularly in poor hydro-meteorological conditions. The goal of the presented system is to support the navigator in decision making, with possible full replacement of his work in the future. Discussed is a method of determining a safe trajectory for the ship, and controlling its movement along this trajectory.
