Earth fault
Earth fault alarm on the 440 V or 230 V system
Ship networks are usually insulated, so one earth fault keeps running and a second one trips. We locate it by insulation-resistance testing and isolating circuits in turn.
The automation and electrical systems your vessel depends on to navigate, communicate, stay safe and stay in survey. Faults found by measurement, not by swapping parts.
To navigate, communicate, stay safe and stay in survey.
Electrical faults on ships repeat in recognisable patterns. Finding the cause takes method: measure, isolate, prove.
Ship networks are usually insulated, so one earth fault keeps running and a second one trips. We locate it by insulation-resistance testing and isolating circuits in turn.
Start sequence, synchroniser, governor, AVR and protection settings tested in order, until the generator starts, synchronises and shares load.
Switch breaker testing, trip unit and protection relay checks, and maintenance of the breaker mechanism.
Loop checks from sensor to display, so a false alarm is fixed at the cause instead of being blocked.
Hydraulic, pneumatic and electrical parts of the control chain checked from the bridge lever to the actuator.
Fault-finding and repair before the next voyage, survey or Port State Control inspection.
When a repair is not enough, we build the control panel in our workshop and commission it on board.
Flag, class and Port State Control inspectors go to the same electrical and navigation items again and again. These are the ones worth checking before they do.
One engineer for a fault-finding visit. A full team on site within a week for a dry-dock or a retrofit. Whatever the size, every job runs the same way.
Written down and agreed before the work starts.
Findings recorded, not assumed.
Progress to the owner every day.
Documentation handed over with the job.
A single repair is quoted per project. Fleets of three or more vessels can have a standing engineering team with priority 24/7 emergency response.
The more of this we have, the fewer questions we need to ask before we can price the work. Send what you have; we'll ask for the rest.

Radar, ECDIS, AIS, VHF and gyrocompass.
Yes. Switchboard work and switch breaker testing are part of our electrical service.
No. Most electrical and automation work is done afloat, alongside or at anchor. We work in Tuzla and Yalova, or on board where the vessel is.
Yes. We build control panels in our workshop and commission them on board.
The equipment make and model, a description of the fault or the scope, and where the vessel is or will be. The checklist on this page covers the rest.
The same team covers agency, engineering and parts, so one contact handles the whole job.
Send the equipment, the fault and the vessel's location. We'll come back within one working day.
