Diagnostics, preventive maintenance and repair for generators installed on board, reviewing the mechanical, electrical and control systems according to the equipment and authorised scope.
Send the make, model, rating and frequency where known, hours, alarms, operational status and location. The information submitted is not a diagnosis or acceptance of the work.
Fault or planned work
Tell us what the generator is doing and under which conditions
A generator that does not start, stops, displays an alarm, overheats, produces smoke or has unstable output requires information and checks before the cause can be assigned to a specific component.

Useful information for the initial review
- Make and model.
- Rated output and frequency where shown on the data plate.
- Operating hours.
- Serial number, optional and excluded from analytics.
- Alarm text or code.
- Whether it starts, continues running and supplies power.
- When the symptom appeared and any recent related work.
- Vessel location and access to the equipment.
- Visible details from the data plate and panel, without unnecessary sensitive information.
One symptom may involve more than one system
The review starts with the reported behaviour, correct equipment identification and available history. Depending on the case and quoted scope, checks may involve mechanical items, cooling, fuel, exhaust, starting, charging, controls, alarms and the electrical side associated with the generator.
Output measurement or load testing is referenced in a specific proposal only where technically appropriate, safely deliverable by CATMAR and included in the scope.
Maintenance matched to the equipment and operating profile
The plan depends on manufacturer, model, hours, calendar, environment and history. According to the equipment and applicable programme, the scope may cover consumables, belts, cooling, fuel, exhaust, starting, charging, connections, controls and alarms.
Findings outside the authorised maintenance scope are communicated before the work is expanded.
