Refrigeration Engineer
A refrigeration engineer looks after everything on board that makes cold air or keeps food cold. That means chilled water plant, air handling units, provision cold rooms, freezers, wine fridges, ice makers and the galley's reach-ins. The job only exists as a separate post on big yachts. Most people who get it are shore-trained refrigeration technicians who have moved to sea.
The jobWhat fills the day
The work is mostly preventive. You log pressures, temperatures and compressor run hours every day, check oil levels, clean condensers and strainers, and track refrigerant use so you spot a leak before it becomes a failure. On a 100m yacht the chilled water system can run several chillers feeding dozens of fan coil units, and if one zone goes warm the guests notice within the hour. Galley and provision kit matters just as much. A failed cold room in the Maldives can mean throwing out tens of thousands of dollars of food.
With guests aboard you work quietly and around their schedule. Cabin fan coil faults get fixed while the guests are at lunch or ashore, and you work with the interior team so you are never in a corridor at the wrong moment. Out of season and in yard periods the work turns heavy: compressor overhauls, replacing expansion valves, flushing chilled water loops, F-Gas leak checks and the paperwork that goes with them. You will also deal with contractors in Antibes, Palma or La Ciotat when a refit includes HVAC upgrades.
Captains and chief engineers hire people with a proper trade background. A refrigeration and air conditioning apprenticeship, three to five years of commercial or industrial work, and current F-Gas or EPA 608 certification are the usual baseline. Experience on chillers, VRF systems or cruise ship HVAC counts for a lot. You still need STCW and an ENG1 like any other crew member. Yachting experience helps, but a strong technician with no sea time can get a first job, especially through a chief engineer who needs a specialist.
Progression goes one of two ways. Some stay specialists and move to bigger yachts or rotational posts on 120m+ projects, where pay and leave improve. Others use the role as a route into general engineering, picking up the AEC, then working through the MCA Y4 and Y3 tickets to become a second engineer. A third group goes back ashore with yacht experience, working for marine HVAC firms, shipyards or management companies as a technical specialist, often on better money than they left.
Skills captains look for
- Chiller and VRF systems
- Refrigerant handling and recovery
- Leak detection and F-Gas records
- Fan coil and AHU servicing
- Electrical fault finding
- Cold room and galley equipment
- Planned maintenance software
A day aboardCharter week, 95m motor yacht, North Malé Atoll, Maldives
Morning rounds of the chiller room. Log suction and discharge pressures, chilled water temperatures and compressor hours, and check the overnight alarm history.
Check provision cold rooms and freezers with the head chef. A fresh delivery arrives by supply boat at ten, so the meat room needs to be holding at temperature.
Clean the sea water strainers on the condenser circuit. Warm water and weed growth in the Maldives cut efficiency fast.
Guests head out to dive. You get into the master suite with the chief stew's say-so to swap a noisy fan motor on a fan coil unit.
Crew lunch in the mess.
Engineering meeting with the chief engineer. Go through refrigerant top-ups for the month and plan a compressor valve job for the next empty week.
Fault on the beach club ice machine. Trace it to a failed float switch, fit a spare and order two more through the purser.
Update the planned maintenance system and F-Gas leak check records.
Off watch. On call overnight for any HVAC alarm.
Pay by yacht sizeMonthly, before tips. Estimates. Bars share one scale.
Pay is usually tax-free and set by yacht size and how much you can do beyond refrigeration. Rotational posts on 100m+ yachts often pay slightly less per month but give equal time off, and charter yachts add tips on top. See the Engineer salary guide for figures from live adverts.

Questions crew ask
Can I get this job without any yacht experience?
Yes, more easily than in most engineering roles. Chief engineers on large yachts want a real refrigeration technician, and a solid shore trade record often counts for more than sea time. You will still need STCW and an ENG1 before you join.
Do smaller yachts hire refrigeration engineers?
Rarely. Below about 70m the engineering team covers HVAC between them and calls in a shore contractor for bigger jobs. If you want to work on smaller yachts, plan to train as a general engineer and bring refrigeration as your strength.
Which refrigerant certification do I need?
European flagged or based yachts expect EU F-Gas Category I, which UK technicians often hold through City & Guilds 2079. Yachts based in Fort Lauderdale or the Caribbean ask for EPA Section 608 Universal. Holding both makes you easier to place.
Is it worth getting engineering tickets on top?
If you want to keep progressing, yes. The AEC and then the Y4 let you stand watches and take a second engineer post later. Specialist pay levels off, while a chief engineer on a large yacht earns far more.
