Data of thermal testing of main engine MAN B & W 6L80MCE bulk carrier type capsize is presents. On the main operational mode conducted parametric diagnostics of technical condition of cylinder group, fuel system and valve gear. Analysis of the performance indicator of the workflow is done with the help of diagnostic D4.0H. To determine the effective performance and mechanical efficiency was applied to a system based on wireless sensors mounted on the shaft of rowing, which record the frequency response of the rotation and working in the mode of MESH-network. To further evaluate the effective performance and to determine the parameters of turbo used methods of spectral analysis. With the methods presented in this paper was to calculate the rotational speed of turbochargers for all operational modes, including for diesel, which tachometers turbines were not provided.

Key words: marine diesel engines, the working process parameters, sea trials tests, spectral analysis.
