Traditional inspection methods often fail to detect early-stage corrosion and defects.&lt;/p&gt;&#13;
&lt;p&gt;&lt;strong&gt;Aim:&lt;/strong&gt; This study aims to evaluate the effectiveness of advanced Magnetic Flux Leakage (MFL) and Eddy Current Testing (ET) techniques for assessing AST bottom integrity and optimizing predictive maintenance strategies in Kazakhstan.&lt;/p&gt;&#13;
&lt;p&gt;&lt;strong&gt;Materials and Methods:&lt;/strong&gt; A dataset of 27 ASTs across different regions of Kazakhstan was analyzed using ROSEN TBIT Ultra technology and ROSOFT for Tanks software. Over 97,000 anomalies were detected and categorized by type, location, and corrosion depth. Analytical comparisons were made across tank sizes, regions, service life, and presence of galvanic protection systems.&lt;/p&gt;&#13;
&lt;p&gt;&lt;strong&gt;Results:&lt;/strong&gt; The results indicate a strong correlation between anomaly density and tank service life, volume, and environmental conditions. MFL/ET scanning proved more effective than traditional ultrasonic methods in detecting internal and external corrosion. The application of galvanic protection showed only partial reduction in corrosion rates. Systematic scanning significantly enhanced defect localization and maintenance planning.&lt;/p&gt;&#13;
&lt;p&gt;&lt;strong&gt;Conclusion:&lt;/strong&gt; The integration of MFL and ET into RBI strategies allows for early detection of defects, optimized maintenance, reduced downtime, and enhanced safety. This approach is especially beneficial for aging infrastructure in Kazakhstan’s oil and gas industry.&lt;/p&gt;</abstract><kwd-group xml:lang="en"><kwd>Storage tanks, MFL, Eddy Current Testing, Kazakhstan, non-destructive testing, ROSEN TBIT Ultra, corrosion detection, predictive maintenance, risk-based inspection, tank integrity.</kwd></kwd-group><kwd-group xml:lang="kk"><kwd>резервуарлар, MFL, құйынды ток, Қазақстан, бұзбайтын бақылау, ROSEN TBIT Ultra, коррозия, болжамды қызмет көрсету, тәуекелге негізделген инспекция, түбінің тұтастығы.</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>резервуары, MFL, вихретоковый контроль, Казахстан, неразрушающий контроль, ROSEN TBIT Ultra, коррозия, прогнозное обслуживание, инспекция по рискам, целостность резервуара.</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Разлив нефтепродуктов в Норильске, 29 мая 2020 года: предполагаемые причины и возможное воздействие на окружающую среду. – ResearchGate. – Доступно по ссылке: https://www.researchgate.net/publication/373680243</mixed-citation></ref><ref id="B2"><label>2.</label><mixed-citation></mixed-citation></ref><ref id="B3"><label>3.</label><mixed-citation>Greenpeace International.
