Within the framework of the research of diagnos-tics and prediction of technical state of ship power plants (SPP) of combined propulsion complexes (CPC) depend-ences of correcting factors influencing components of thrusts and moments, proportional dimensions of model and real thrusts (THRs), tied to the original geometry were obtained. This was done by formalizing the physical model of the azimuth thruster with the means of identifying the degradation effects on the flow lines of the propellers by methods of computational hydrodynamics. The technique of improving the structure of the mathematical models of the SPP CPC according to experimental studies by measur-ing the input and output parametric coordinates of the THRs CPC of a vessel operating in the dynamic positioning mode is announced.
