Marine & industrial generator specialists · Townsville QLD
CMD Generators services, tests and repairs marine gensets and land-based standby plant across Townsville & North Queensland — scheduled maintenance, breakdown attendance, load bank testing and commissioning. Every visit ends with a written technician report.
Field log
One job a month, written up — what came in, what it turned out to be, and what it took to put it right.
No fuel being delivered — a combination of the lift pump failing and the pre-fuel filter being clogged. Replaced them both, cleaned out the lines and bled the system, ran it up under load and left it back on auto.
Replaced all filters and oil, tested coolant and performed running checks — including a combustion leak test and a cooling efficiency test.
Attended a marine generator where the client had reported replacing the start battery twice in three months. Attempted to start the generator and noticed a big voltage drop. Found a seized engine causing the starter motor to load up and drain the battery. Diagnosed a failed salt water exhaust mixer leaking salt water back into the cylinder. Quoted replacement.
Scheduled in for a service and carburettor clean. Found scale built up inside causing a clogged jet. Removed the scale, cleaned it out and replaced the oil and spark plug.
Capability
Whether it's a genset in an engine room or a standby unit behind a switchboard, the work is the same discipline: find the real fault, fix it properly, and write down what we found.
Onboard gensets on commercial vessels, charter boats and private craft — the units that keep air-conditioning, refrigeration and navigation live at anchor.
Land-based diesel plant that has to carry the site when mains power drops — backup sets, prime power and hire units.
A set that has never been loaded is an untested set. We prove capacity under real load and document the result.
Won't crank, won't hold load, shutting down on alarm. We come to the vessel or the site, diagnose it on the spot, and tell you straight what it needs.
Recent work
Sets we've had our hands on — on site, in the plant room and on the workshop floor.
Equipment
Diesel and gas sets across the range you'd expect on a working coast — from a few kVA in a lazarette to standby plant behind a main switchboard.
| Category | Typical equipment | Common work |
|---|---|---|
| Marine | Onboard diesel gensets, sound-shielded units, raw-water and keel-cooled installations | Hour-based servicing, impellers and heat exchangers, exhaust elbows, injector and fuel faults |
| Standby | Enclosed and open-frame standby sets, ATS and changeover panels, integrated fuel tanks | Scheduled servicing, no-start and alarm faults, battery and charging systems, exercise runs |
| Prime power | Continuous-duty sets, hire fleet units, remote-site plant | Long-interval servicing, oil and coolant analysis follow-up, wear-item replacement |
| Diesel engines | Genset prime movers and auxiliary diesel engines, naturally aspirated and turbocharged | All diesel engine service and repairs — routine servicing, fault diagnosis, fuel and injection systems, cooling and exhaust, turbochargers |
| Control systems | Digital genset controllers, remote annunciators, auto-start circuits | Alarm interrogation, sensor and sender faults, setting checks, statistics download |
| Alternator end | Brushless alternators, AVRs, excitation circuits | Output and regulation faults, insulation checks, bearing noise, load-holding issues |

How a job runs
The order matters — each step depends on the one before it, and skipping the diagnosis stage is how generators get parts thrown at them.
Tell us the make, model and what it's doing. We confirm whether it's a callout or a booked service, and when we can be there.
On site or alongside. We record the nameplate details and pull the controller statistics before touching anything.
Fault-find from the evidence — alarms, readings, condition — not from guesswork. You get told what's actually wrong.
Repaired on the spot where parts allow. Anything larger is quoted before it starts, with the options explained.
A written technician report covering findings, work performed and outstanding items — issued after every visit.
Documentation
Plenty of generator work disappears into a verbal handover and a line on an invoice. Ours doesn't. Every attendance produces a CMD technician service report — the same format whether it's a fifteen-minute alarm reset or a full commissioning run.
It builds a service history you can hand to a surveyor, an insurer or the next owner — and it means the next technician on the job isn't starting from zero.
Where we go
The workshop is in Townsville City. Most work is mobile — we come to the vessel, the marina or the site.
City, marinas, port precinct and surrounds — standard callout area.
Regional attendance up and down the coast by arrangement.
Alongside at the marina, on the hardstand, or at anchor by arrangement.
Standby plant on sites away from town — travel quoted up front.
Get in touch
Tell us what the unit is and what it's doing. The more you can give us from the nameplate and the controller, the better prepared we arrive.
