construction. Their availability and utilisation rate determine the progress of the project. An unexpected failure can halt operations for long periods or reduce excavation performance, significantly affecting project timelines and budgets.<\/p>\n<p data-start=\"1028\" data-end=\"1368\">TBMs are highly complex, highly mechanised, and digitised machines \u2014 essentially factories that advance as they excavate \u2014 making them ideal candidates for the development of predictive maintenance analytics. Moreover, the repetitive nature of TBM work cycles helps in identifying anomalous patterns compared to normal operating conditions.<\/p>\n<p data-start=\"1370\" data-end=\"1751\">Currently, preventive maintenance strategies are used to prevent machine failures, in which inspection and maintenance are performed according to a planned schedule. However, there are no technologies that allow these failures to be anticipated ahead of time and enable maintenance work to be adapted to the real needs of the process.<\/p>\n<p data-start=\"1753\" data-end=\"1986\">In addition, predictive maintenance enables remote monitoring of the machine\u2019s condition and performance, even during normal operation, allowing operational adjustments that increase performance.<\/p>\n                                        <\/div>\r\n                                    <\/div>\r\n                                <\/div>\r\n\r\n                            <\/div>\r\n                        <\/div>\r\n                    <\/div>\r\n                <\/div>\r\n\r\n                <div class=\"tab\">\r\n                    <input type=\"checkbox\" id=\"faq-min-chck_acc_dest_2_default\" >\r\n                    <label class=\"grid tab-label\" for=\"faq-min-chck_acc_dest_2_default\">\r\n                        <div class=\"label--m\">2<\/div>\r\n                                                    <h3 class=\"title--m\" data-attribute=\"Opportunity\">\r\n                                <span>Opportunity<\/span>\r\n                                <div class=\"arrows\"><svg width=\"40\" height=\"40\" viewBox=\"0 0 40 40\" fill=\"none\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"><path d=\"M35 12.5L20 27.5L5 12.5\" stroke=\"#FF0000\"><\/path><\/svg><svg width=\"40\" height=\"40\" viewBox=\"0 0 40 40\" fill=\"none\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"><path d=\"M5 27.5L20 12.5L35 27.5\" stroke=\"#FF0000\"><\/path><\/svg><\/div>\r\n                            <\/h3>\r\n                                            <\/label>\r\n                    <div class=\"tab-content\">\r\n                        <div class=\"grid full-width\">\r\n                            <div class=\"grid-container\">\r\n\r\n                                <div class=\"module-wysiwyg \">\r\n                                    <div class=\"grid\">\r\n                                        <div class=\"grid-container\">\r\n                                            <p data-start=\"2014\" data-end=\"2321\">Predictive maintenance allows failures in critical TBM systems to be anticipated through advanced analysis of operational data, reducing unplanned downtime and safety risks.
