In the present time the technical progress make us use more and more complicated machines in our everyday life. In the case of the technology used at sea the necessity of highly specialised service is especially evident. The diagnostic systems elaborated to support the exploitation of the vessel power plant with gas turbines are presented in the paper. Application of computer simulation for diagnosing a technical state of gas turbines rotor sets should be applied during calculation and project process. During engine assembly, the rotating components are mounted with great care with the main objective of minimising shaft unbalance. However, even with the best of care, such factors as machining imperfection, differential thermal expansion etc cause a small residual unbalance of gas turbine rotor. The dynamic problems of Marine Gas Turbine Engines are connected with such basic elements as rotors, bearings, struts of bearings, engine body and type of substructure.
