One of the aspects of marine engine operation is defining its torque load. It is crucial for both the general estimation of the engine working parameters value reflecting the engine’s operational condition and for comparing its current condition with the previous one (recorded during the last check of the engine performance) or its state during the trials at the engine test bed. In the paper there have been analyzed the well known and recommended by marine engine manufacturers methods of estimating marine engine torque load without any torquemeter used, based exclusively on measurable working parameters of marine engines. To most marine engines the above mentioned indirect methods apply since so far the systems of taking torque direct measure have been neither common nor standard engine room equipment. Methods based on parameters obtained during engine indicating (engine performance check), fuel rack setpoint or load indicator reading and turbocharger system working parameters have been presented. Example nomograms for engine torque load estimation for engines manufactured by famous makers have been shown. Some of the methods have been compared based on parameters obtained during engine performance check. Discussion on the advantages and disadvantages presented methods has been presented.
