EFFECTS OF VIBRATION ON THE CREWS OF SEAGOING SHIPS

The ways in which ship vibration effects the human body, including the effects of long-term exposure, are briefly discussed, and it is mentioned that present knowledge of the biological effects of vibration does not allow an all-embracing exposure limit based on objective criteria to be specified. The Authors then explain the methods of measuring and assessing ship vibration in accordance with the East German standard TGL 22312, entitled "Effect of Mechanical Vibrations on Man", which gives acceleration limits (effective from Jan. 1972) for mechanical vibrations, in the 1 to 90 Hz frequency-range, that enter the human body through the feet, seat and/or back. The influence of various factors on the measurements is mentioned, and that of ship loading (i.e., whether laden or in ballast)is shown in a graph. The article also discusses the methods and results of some investigations, conducted jointly in 1973-76 by East German and USSR authorities, in which noise and vibration measurements and analyses were carried out in the accommodation spaces of merchant ships and fishing vessels. The investigation also included the study of answers to a questionnaire, completed by the crews, on their reactions to noise and vibration; some of these results are summarized and discussed. The investigations are continuing.
