A technology for seabed installation of an underwater massive tank

Abstract

This paper attempts to determine the law of motion of a tank as a large volumetric massive structure when immersed in a resisting liquid medium. The authors propose two methods for its determination. Dependence graphs of coordinates, speed, acceleration of the tank versus time are plotted. The dependence of time and speed of lowering of a massive storage structure on the volume of pumped water is determined. In addition, the range of the optimal volume of water pumped inside the tank for the purpose of its soft landing is determined.
