Abstract: This study aims to investigate the applicability and effectiveness of infrared thermography for condition monitoring of machinery systems through onboard measurements.Thermographic inspections of machinery were carried out on two separate vessels, using a thermal camera with a thermal sensitivity of 60 mK, under different engine operating conditions, covering the main and auxiliary engines, their connected system components, engine room ventilation systems, and electrical equipment.Measurement and analysis were conducted according to ISO 18434-1, ISO 18434-2, and ASTM E1934-99a standards for thermographic inspection.According to the inspection results, which included 152 filtered thermograms, most components on both vessels operate normally, except for overheating in electrical panel switches on the first vessel (V-1) at full load and insulated exhaust areas on the second vessel (V-2) with temperatures exceeding 350 °C under normal operating conditions.Additionally, analysis of the thermograms obtained from the measurements the temperature distributions, anomalies, and thermal behavior characteristics of the equipment were revealed.Based on these data, a systematic thermogram inventory was established and subsequently used to propose a preliminary, conditionbased, maintenance-oriented inspection framework for future monitoring.
