Monitoring is a continuous registration of vessel’s vibration parameters simultaneously with registration of its movement and navigation parameters and also severity of ice conditions. In this paper the monitoring system main features and main principles of its installation on vessel are presented. The experience of practical use of monitoring system is presented by data obtained on research ice-going vessel which had ice class Arc7. On basis of obtained data there were determined statistical characteristics of vibration parameters depending on travelling regimes and ice severity conditions. In this paper it is proposed to characterize the severity of ice conditions by total power on shafts and vessel speed ratio. These results could be used for developing statistical attitudes to principle of vibration rates for ice-going ships.
