The face pattern method is considered to be preferable for marine engine monitoring because it is suitable for understanding correlations of multi-variates at a glance and noticing their delicate changes in details. This report deals with a study of application of the face pattern method to the condition monitoring of marine engine systems. Features of the face pattern display are analyzed experimentally and appropriate assignment of state variables of marine engine performances to variables for drawing face patterns are found for the condition monitoring. The state variables in abnormal states of a marine turbine plant system and a diesel one are displayed on a cathod ray tube by the face pattern method.
