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 vibration meter Examiner 1000 and the vibrations transmitted to human body, with vibrometer Maestro 01dB. It is found that if the the for navigation bridge and for the main deck, the average of these values is 0.932m/s 2 , respectively 0.75m/s 2 , for engines room this average is 5.707m/s 2 and for the staff on the navigation bridge and on the main deck, the average of these values is 2,221m/s 2 , respectively 1,773m/s 2 ; for those in the engine room this average is 5,934m/s 2. It can be seen that absolutely all the values for the daily exposure action value, standardized to an eight hour reference (0.5m/s 2) are exceeded.

“…Neurological diseases can also occur, such as: Peripheral nerve entrapment, peripheral neuropathy, disorders of the central nervous system, neurological disorders secondary to malformations, injuries, fractures or surgery in the hand, arm or neck and musculoskeletal diseases. Among these, the most frequent are: Severe tendinitis or tenosynovitis in the hand-wrist, elbow or shoulder, severe unspecific cervicobrachial disorders, severe Dupuytren's contracture, severe degenerative bone and joints disorders in the upper limbs and the neck, severe deformities of the bone and joints of the upper limbs secondary to malformations, injuries, fractures or surgery, severe myopathies [7,8].…”

This paper studies the noise and vibrations transmitted to the crew of a pusher with eight barges sailing upstream the Danube River, between Cernavoda and Drobeta, with a staff consisting of a captain, one coxswain, one mechanic and three sailors. The research was conducted over a one-week period in August 2018. The navigation time was 24/24 h and the seafarers’ schedule was 4/8. Determinations were made on three different workers: Coxswain, mechanic and sailor. The meteorological parameters and the Danube river levels, the sound level and the transmitted vibrations, as well as the body temperature and blood pressure of the subjects were measured. The periods of activity and sleep were analyzed by means of an actigraph. Our research findings indicate that people worked overtime, slept less than necessary and, generally, did not observe the official program. The noise (LEP,d = 92 dB) and vibration levels (a total exposure A(8) = 4.1 m/s2) also contributed to the sleep disorder. Such effects were accompanied by increased body temperature and blood pressure. Synthesizing, it can be concluded that: The peak (acrophase) of the work capacity was from 9:00 to 11:00 and from 17:00 to 19:00, which represent the maximum efficiency periods. More specifically, the highest mental performances were recorded in the morning, while the maximum physical ones were to be seen in the afternoon. The minimum efficiency period was from 13:00 to 15:00. Decreases in the work capacity were identified at 23:00 (reasonably low level) and 3:00 (extremely low level).
