The caisson foundation has developed into a viable substitute foundation for offshore structures, particularly for offshore wind turbines (OWT). These OWT caisson foundations experience a combination of lateral loads, vertical loads, and overturning moments. An accurate response detection to horizontal loads guarantees the effective operation of these foundations. Due to the significant costs and time constraints associated with experimental techniques, coupled with the restricted utilization of working conditions, finite element approaches have demonstrated efficacy as an analytical means to evaluate foundations’ failure and displacement mechanisms. The development and verification of the finite element model to simulate the lateral load-bearing properties of the caisson foundation used in offshore wind turbines are described in this study. This study automates the simulation and data extraction using ABAQUS-Python, making it easier and faster. The experimental data from the literature was used to validate the developed numerical model. The automation procedure and simulation matrix are discussed in detail.
