Abstract: Marine structures are subject to environmental interference all the time, and the simulation of the ocean environment significantly affects the realism of the marine simulators. The ocean environmental fields are generated by the numerical wave model, and the real ocean databases are developed based on SQLite. The actual wind, current, and wave information are obtained from the databases to keep consistency with the actual sea. The environmental disturbances are modeled and both the spatiotemporal-varying features and the coupling effects are brought into the simulation. The real voyage cases are reproduced by the proposed simulation method. The measured data from the on-board sensors are utilized for validation. The simulation results coincide with the measured data, which could further improve the physical reality of marine simulators.

Key words: marine simulator, environmental disturbances, realistic ocean database, on-board sensors
