A ship uses four Sabroe 163 units and two Sabroe 128 units as the chiller for the general and special air conditioning systems. After ten years of operation and use, it entered the overhaul. It is planned to determine the damage condition of the heat exchanger tubes of the evaporator and the condenser by eddy current method to determine the next maintenance plan. Due to the ship’s docking overhaul, the eddy current flaw detection has been equipped with conditions for draining the equipment, cleaning the heat exchange tubes, purging the inner wall of the heat transfer tubes, and drying. This eddy current testing was performed by a maintenance engineer using a dedicated device that was calibrated.
