Continuous monitoring of the technical condition of gas turbines, defect identification, failure prevention, and optimization of operation, maintenance, and repair processes are relevant tasks for the operators of this equipment. Various machine learning methods that are already being used in the field of gas turbines can help solve these tasks. The limiting factor in this regard is the lack of real operational data. This study examines the possibility of using synthetic data for training and testing machine learning models to determine the level of technical condition of a gas turbine installation. An open dataset created by other researchers using a mathematical model of a marine gas turbine engine was selected for analysis. The research presents the accuracy values obtained by different methods of evaluating machine learning models. The random forest model demonstrated the best results. It was found that when developing machine learning-based solutions for engineering tasks, additional methods for assessing the accuracy of predictions are required. The further development of this work is associated with the development of a proprietary mathematical model of a gas turbine installation capable of considering the influence of specific defects to create datasets for analysis and further research
