Abstract :
In control systems using conventional technologies of signal analysis, results of monitoring of change in seismic stability of offshore structures are determined when they have taken express form. The offered technologies will allow detecting those changes in their initial latent period. It will thereby be possible to organize timely preventive measures to stop further serious deformations in most vulnerable units of a structure, which will allow reducing the general volume of repair works, expenses and unexpected destructions considerably.
