Mobile drilling rigs are particularly susceptible to overturning due to the high location of their centre of mass. In some cases, overturning occurs due to a failure in the subsoil. Until now, machine operators are solely responsible for monitoring the machines' stability, and assessment of dangerous conditions is based mainly on experience. This investigation aims to set the grounds for elaborating a digital twin to online monitor the machine's stability to prevent overturning. Stress transmitted to the ground, tracks' settlement, and bearing capacity are calculated from a multibody simulation (MBS) and following existing standards. Furthermore, soildependent stability diagrams are generated to describe the stable location of the machine's centre of mass and predict soil failure. Results offer the possibility to function as an online alarm system running parallel to the machine's operation and alerting the operator about dangerous conditions.
