This paper presents a cross-sectional analysis of the noise inside the engine room of a commercial ship that navigates a section of the Romanian Danube segment. The noises of river ships are heard inside the ship by the crew as well as by the passengers, but also on the outside of the ship by the aquatic and riverside fauna. Determinations took place on a 6-bar pusher ship for 3 days, on the Danube, between 17 and 19 February 2018, on the route Braila (170 km) - Calarasi (km 365). On average, were made about 100 k...

This paper presents a cross-sectional analysis of the noise on the navigation bridge of a commercial ship that navigates a section of the Romanian Danube segment. This room is important because here are given all the commands for safe navigation so the conditions inside it must be of the highest quality. Determinations were carried out on the pusher, between Braila and Calarasi, in February 2018, in very difficult weather conditions. The noise was measured with BlueSolo 01dB sonometers. These were placed on the na...

This paper examines the level of vibrations transmitted to the crew on a river ship. This ship made a test cruise on the Danube, between Braila and Galati, round-trip (32Km). This cruise was done before the ship was repaired, to compare the levels of vibrations before and after the repairs and to check their efficiency. There were determined both the vibrations produced by the ship's equipment (engine, generator) and those to which crew members are subjected in the areas where they spend most of their time. To det...
