Pump and compressor automation manages the configured demand, sequencing and protection functions. Start permissives and minimum operating conditions differ between fluid pumps and gas compressors.
Seanav Marine provides independent service assessment. Send the equipment identity, symptoms and attendance window so the required capability, parts and any manufacturer involvement can be confirmed.
What should the service assessment check?
The following items define a starting scope for a competent service assessment. The actual test method and acceptance criteria must come from the installed equipment documentation and the agreed job scope.
- Pressure and temperature feedback.
- Duty/standby and start/stop sequence.
- Motor or drive status and protection.
- Lubrication, cooling and unloading interfaces where fitted.
What must be distinguished before testing?
A common controller platform does not make different machine types interchangeable. Keep the maker’s mechanical protection requirements in the scope.
Why identify whether a panel controls a pump or compressor?
Both may use motor starters, but their process feedback and operating sequences differ. Define the actual machinery and controlled variable. A generic start/run test cannot validate every unloading, standby or process-protection function.
Details that help assess this equipment
- Machinery and controller models.
- Pressure/level or other process demand.
- Start, load/unload and trip records as fitted.
Equipment references and their scope
- Atlas Copco: compressor controllers — Controller monitoring, sequencing and compressor service-data functions.
- Schneider Electric: contactors and motor protection — Motor-starter switching and protection functions.
These references explain equipment or system examples. They do not establish the fitted configuration, SEANAV manufacturer authorization or a vessel’s acceptance limits. Use the installed model’s documentation for the actual work.

How service is planned
Agree the affected machinery, safe isolation, operational restrictions and equipment-specific test plan with the vessel. Preserve as-found settings and available configuration backups. Confirm proposed changes and compatible replacements before work.
Record the completed work, functional-test results, outstanding defects and operating limits. Changes affecting approved functions need the appropriate maker, owner or approval-body review.
Maintenance, survey and documentation
Maintenance intervals and calibration methods depend on the manufacturer’s instructions, service conditions and vessel PMS. There is no blanket annual calibration or five-year overhaul rule for every automation component. Statutory and Class survey requirements must be established for the particular vessel and equipment.
A service report records the work performed and observed results. It does not by itself issue or renew a ship’s statutory certificate. Manufacturer authorization, specialist calibration and survey witnessing must be confirmed where required; Seanav Marine’s independent service role does not imply direct OEM agency or universal Class approval.
Request pump and compressor automation support
Send the vessel name and IMO number, port, ETA/ETD, equipment maker and model, fault description, alarm screenshots and relevant drawings or logs. State whether the request involves routine maintenance, a defect, replacement, retrofit or an upcoming survey. Attendance depends on access, engineer availability, parts and the confirmed scope.
