This article examines the factors causing accidents and failures due to structural failures in hydraulic oil and gas installations operating in the Caspian Sea. It also provides a comparative assessment of errors and gaps in installation reporting on seismic and extreme hydrometeorological impacts.
It is shown that periodic inspection and diagnostic work, crucial for ensuring the operational safety of installations, does not comply with safety legislation. As a result of these safety gaps, calculations have shown that the fatigue life of many installations is not ensured.
Based on the study’s results, it is recommended to use seismodynamic monitoring to implement appropriate preventive technical and organizational measures for the early detection and prevention of potential accidents and installation failures.
