Job Summary
This hands-on internship trains you in two areas: machinery condition monitoring (vibration measurement and thermal imaging) and marine HVAC servicing. You will work alongside our senior engineers onboard vessels, preparing you for a full-time Technician role.
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
- Perform leak testing, nitrogen pressure testing, vacuuming, and refrigerant charging to ensure system integrity
- Conduct basic electrical checks including continuity, insulation resistance, voltage, and current measurements
- Read and interpret wiring diagrams and control schematics to support troubleshooting and repairs
- Prepare tools, instruments, and service reports accurately to support job completion and documentation
- Follow safe working practices onboard vessels, including safe procedures when working near live electrical panels and running machinery
Preferred competencies and qualifications
- Minimum Nitec, Higher Nitec, or Diploma in Electrical, Mechanical, Mechatronics, Marine, Facility Technology, or Air-Con & Refrigeration, or currently pursuing one
- Comfortable using handheld measuring instruments and recording data carefully. Accurate readings matter more than speed
- Basic computer skills for entering and organising measurement data
- Able to handle physical work such as lifting, climbing, and working in engine rooms, at heights, and in confined spaces
- Willingness to work overtime and weekends as required by vessel jobs
- Willingness to travel overseas on short assignments (typically a few days to two weeks) to attend vessels in port or anchorage
