Rehoboth Marine Equipment Repair L.L.C provides marine alternator and motor rewinding in Fujairah and shipboard generator repair services across the UAE from our rewinding bay in the Al Hayl Industrial Area. Our electrical team covers the full chain from the machine to the board: stator and rotor rewinding, AVR and excitation faults, vessel switchboard troubleshooting, automation and instrument calibration, and Caterpillar ET electronic diagnostics on marine CAT engines.
Attendance is onboard at Fujairah anchorage and Port of Fujairah, Fujairah anchorage, Khorfakkan, Port Rashid, Dubai Maritime City, Jaddaf, Khalid Port Sharjah, Ajman Port and Marina Port Abu Dhabi, or in our workshop when a machine has to be stripped, rewound, impregnated and balanced. Insulation resistance, polarisation index and load test results are handed over in writing.
From a burnt-out generator to a nuisance alarm on the control panel, these are the disciplines we cover in-house.
Stator and rotor rewinding, insulation resistance and polarisation index testing, vacuum varnish impregnation, bearing renewal and dynamic balancing.
Read moreGenerator rewinding, AVR and excitation fault finding, rotating diode and slip ring renewal, and on-load verification once the machine is back in the ship's system.
Read moreMain switchboard and emergency switchboard fault tracing - breakers, protection relays, synchronising gear, blackout and earth fault investigation.
Read moreFault code reading, live parameter logging under load, sensor and harness circuit checks and injector trim file loading on marine CAT engines.
Read morePressure, temperature and level transmitter calibration, control loop tuning, alarm and safety trip testing on engine room control panels.
Read moreControl valve calibration, hydraulic and pneumatic actuator overhaul, positioner and solenoid renewal, and set point and stroke testing.
Read moreSuperintendents ask what we can actually connect to and measure before they hand over a fault. This is the toolset our electrical team uses.
| Tool / equipment | Used for |
|---|---|
| Caterpillar ET (Electronic Technician) | Marine CAT engine diagnostics - active and logged fault codes, live parameter logging, injector trim file loading, configuration and post-repair verification |
| Insulation resistance and polarisation index testers | Motor, generator and cable insulation condition, moisture ingress assessment before a rewind decision |
| Clamp meters, power quality and phase sequence testers | Load balance, phase rotation and supply quality checks on the ship's distribution system |
| Protection relay and breaker test sets | Switchboard breaker function, overcurrent and reverse power protection, synchronising checks |
| Loop calibrators and pressure / temperature references | Transmitter and instrument calibration, control loop and alarm trip verification |
| Dynamic balancing machine and vibration meters | Rotor balancing after rewind, bearing condition and alignment verification |
When a superintendent reports nuisance tripping, a blackout or an earth fault, this is the checklist we work through onboard - findings first, parts afterwards.
We take the alarm printout and the engineer's account of what happened, in what order, and under what load. A fault that appears only on load change points somewhere different from one that appears at rest.
The affected section is isolated and locked off. Connections are checked for heat damage and slackness, and the board inspected for tracking, moisture ingress and salt or oil contamination.
The earth fault indication is confirmed with an insulation tester, then the circuit is split section by section to identify the offending feeder rather than condemning the whole board.
Breaker operation, overcurrent settings, reverse power and preference trips are checked against the ship's electrical drawings, and the synchronising and governor response confirmed.
If the fault sits on the machine side, insulation resistance and polarisation index are measured, the AVR, rotating diodes and slip rings checked, and we advise repair on board or a workshop rewind.
The repair is carried out, the section re-energised in a controlled sequence and load tested. Test values and the fault cause are issued to the vessel in writing.
Our electrical engineers attend at Fujairah anchorage and across UAE ports, with a rewinding bay in Al Hayl Industrial Area for machines that have to come ashore.
Yes. Rewinding is done in our own bay in the Al Hayl Industrial Area, Fujairah - stator and rotor rewinding, vacuum varnish impregnation, bearing renewal and dynamic balancing, with insulation test results handed over.
Yes. We connect Caterpillar ET to marine CAT engines onboard at Fujairah anchorage or in our workshop, read active and logged codes, log live parameters under load and re-verify the engine after repair.
The alarm printout, the ship's electrical drawings if available, the load condition when the fault appeared, and the generator maker and rating. That lets us arrive with the right test gear.
Yes. We calibrate pressure, temperature and level transmitters, tune control loops, set control valve positioners and test alarm and safety trips on engine room panels.
Light faults - AVR, diodes, slip rings, bearings - are handled onboard. A failed winding needs a workshop rewind; we lift the machine to our Fujairah workshop and return it tested and balanced.
