Abstract

The process of ballasting of ships used for transportation of non-standard cargoes, during their operation on waves, is studied. When auditing the ballasting process it is established that the presence of parasitic air volumes inside the tanks leads to an increase in the angle of the ship's list. To eliminate this drawback, a new technology for destroying parasitic air bubbles by means of jets under pressure is developed. During the operation of the developed technology on the ship a number of positive results are obtained. The angle of the ship's list is reduced from 2 to 1.5 degrees when the sea surface is 0.5 m high. The level of uncontrolled ship’s list on waves with the operating system of destruction of the parasitic air volume and without it is different. At a wave height of 0.3 m to 0.12 degrees, with a wave height of 0.6 m to 0.65 degrees, and at 1 m to 1.2 degrees.
