An AMS collects equipment alarms and operating values so the watchkeeper can identify abnormal conditions. Alarm acknowledgement records operator response; it does not remove the fault or reset an independent trip.
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.
- Open-circuit and out-of-range indications.
- Alarm priorities, delays and deadbands against approved lists.
- Audible and visual indication at required stations.
- Watchkeeper call and engineer alarm interfaces.
What must be distinguished before testing?
Do not suppress repeated alarms by widening setpoints without an engineering assessment. Distinguish sensor faults from genuine process excursions.
Does acknowledging an AMS alarm clear its cause?
No. Acknowledgement records operator response; it does not correct the measured condition or reset an independent protective function. Identify whether the alarm represents a process excursion, signal fault or communication failure before changing delays or setpoints.

Equipment references and their scope
- Kongsberg Maritime: K-Chief vessel automation — Examples of integrated monitoring, alarm and configured auxiliary-control 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 alarm monitoring systems (ams) 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.
