Securing Kazakhstan’s Oil Refineries on the Steppe
Kazakhstan’s energy corridor between Atyrau and Aktobe sits atop the active Caspian Depression fault system. Refinery shutdowns caused by earthquakes cost the national economy millions of dollars per day, so KazMunayGas has begun installing Friction Pendulum Seismic Isolation Bearing systems beneath critical distillation columns. In the Tengiz field, engineers have calculated that a Friction Pendulum Seismic Isolation Bearing layer can reduce seismic acceleration transmitted to spherical storage tanks by 85 %, preventing catastrophic hydrocarbon fires. Because the steppe is also subject to extreme temperature swings, the latest Friction Pendulum Seismic Isolation Bearing models use low-temperature grease that stays pliable at –40 °C. During the 2023 Aktau retrofit, 240 Friction Pendulum Seismic Isolation Bearing units were installed in only six days, allowing the refinery to stay online while workers slid each bearing into place beneath live pipelines. Local welders have formed cooperatives to fabricate custom pedestals that interface with imported Friction Pendulum Seismic Isolation Bearing shoes, creating new jobs and reducing dependence on foreign steel. The Kazakh government now requires any new petrochemical facility above 10 MW to include at least one row of Friction Pendulum Seismic Isolation Bearing isolators in its foundation design. When investors ask why the extra cost is justified, managers simply reply: “One Friction Pendulum Seismic Isolation Bearing today prevents a billion-dollar fire tomorrow.”
