Scope of work
- Survey of the existing system and a record of every active and inhibited point
- Upgrade or replacement of AMS processing units and operator screens
- Limit, hysteresis and delay setup per point
- Alarm grouping and prioritisation into critical / warning / status
- Extension alarm system, duty-engineer call and dead-man alarm
- Remote indication on the bridge, in the engineer's office and in cabins
- Time-stamped alarm logging with export for incident analysis
- Repair of field wiring, junction boxes and sensors that have been bypassed
Typical symptoms & failures
- Dozens of permanently active or inhibited alarms nobody clears
- False alarms in specific weather conditions or at a specific load
- Points still live for machinery removed years ago
- A siren that never reaches the duty engineer's cabin
- An alarm log that will not export, or carries the wrong time
- An AMS screen that freezes and only recovers on restart
What you receive
- A complete, current alarm point list with limits and delays
- A list of inhibited points with the reason and a repair proposal
- Test protocol per point and per group
- Exported alarm log in a readable format
Equipment & protocols
- PLC-based AMS platforms and industrial panel PCs
- Pressure, temperature, level, flow and vibration instrumentation
- Modbus RTU/TCP and CAN bus to engines and subsystems
- Work aligned with class requirements for UMS/E0 notation where applicable
Frequently asked questions
The vessel holds UMS notation. Does an AMS upgrade affect it?
It does, which is why the job is planned together with the technical department so class requirements are met and the right documentation is available for survey.
Can false alarms be reduced without losing monitoring?
In most cases yes. False alarms almost always come from a wrong limit, a missing delay or a failed sensor — not from a system that is 'too strict'.
How long does an AMS clean-up take?
Survey and limit correction is typically 2–4 days onboard; sensor replacement depends on spares availability.
