Responsibilities

Carry out vibration measurements on marine machinery such as pumps, motors, fans, compressors and blowers using handheld vibration analysers and thermal instruments

Conduct thermal imaging (infrared) surveys of electrical panels, switchboards, motors and mechanical equipment onboard vessels

Record measurement data accurately, follow set measurement points and routes, and upload readings for engineer review

Assist senior engineers in interpreting vibration and thermal readings to identify developing faults

Assist in servicing and repairing marine air-conditioning, refrigeration, and ventilation systems onboard vessels

Service compressors, fan motors, pumps, air handling units (AHUs), and fan coil units (FCUs) under supervision
