Abstract

Accidents and their causes at some Antarctic stations are considered. It is shown, that the wind speed can reach 50-90m/s in the Antarctic region. This load can have a significant impact on the fuel tanks that are installed outdoors. Tank from the Ukrainian Antarctic Vernadsky Station is considered as example. Causes of failure of such tanks are analyzed. It is shown that the tank (which is considered) is in adverse climatic conditions, which may eventually lead to its destruction. The way of passive protection of fuel tanks against the wind load is proposed. The results of the simulation in the ANSYS software package are analyzed. Velocity and pressure fields are considered. The effectiveness of the proposed way of passive protection of fuel tanks against wind load is shown by the example of the tank from the Ukrainian Antarctic Vernadsky Station.
