Abstract

This paper analyzes the vibrations transmitted to the entire human body by the equipment of a ship. The measurements were made on the Danube river, from the entrance to Romania to the point where the Danube Delta begins, along 1000km, for 6 runs. The vibrations of the navigation bridge, on the main deck and in the engines room were measured with the vibration meter Examiner 1000 and the vibrations transmitted to the human body, with vibrometer Maestro 01dB. It is found that if for navigation bridge and for the main deck, the average of these values is 0.932m/s2, respectively 0.75m/s2, for engines room this average is 5.707m/s2 and for the staff on the navigation bridge and on the main deck, the average of these values is 2,221m/s2, respectively 1,773m/s2; for those in the engine room this average is 5,934m/s2 . It can be seen that absolutely all the values for the daily exposure action value, standardized to an eight hour reference (0.5m/s2) are exceeded.
