NACOS Platinum MOS/MCS/PMS/EMS/EPS/PTS by NACOS Lyngsø Marine A/S. DNV TA certificate TAA00003TY.
Inspector Detail
▸
Common issues
- Sensor/field signal loss causing false alarms in the monitoring system
- Network or bus communication faults between engine room and bridge stations
- Software/firmware version mismatches following a partial system upgrade
- Operator workstation/display hardware failure or overheating
- Power management system load-sharing faults during generator changeover
- Engine manoeuvring system command/feedback discrepancy against the engine control system
- UPS/backup power failure affecting system redundancy
Inspection checklist
- Function-test the alarm and monitoring system against known trip points
- Verify automatic generator start/stop and load-sharing sequence in the power management system
- Test engine manoeuvring/bridge control handover and lever response
- Check redundant network/bus link integrity where a dual LAN is fitted
- Verify UPS battery backup autonomy time
- Check operator workstation/panel functionality and screen legibility
- Review alarm printer/logger records for completeness
- Confirm software/firmware revision matches the approved configuration
- Test bridge/engine room control changeover
Service intervals
| Alarm/monitoring system function test | annual, coordinated with class survey |
| UPS battery test/replacement | battery typically renewed every 3-5 years |
| Software backup and configuration check | annual, or after any modification |
| Power management changeover/load-sharing test | annual |
| Network/bus diagnostic check | annual |
Critical spares
- Operator workstation/display unit
- I/O card or interface module
- UPS battery set
- Redundant LAN network switch
- Control cabinet power supply unit
Safety
- Loss of remote control/monitoring during software work - confirm local manual control is available before starting maintenance
- Electrical hazard when working inside control cabinets - isolate and lock out before card replacement
- Unintended equipment start from a stale command during system testing - coordinate with the engine room/bridge before any test
Class survey
Note: the catalog category for this entry (Cargo Level & Temperature Gauging) does not match the manufacturer's actual product. NACOS Platinum (Lyngso Marine/NACOS Marine) is an integrated bridge and engine room automation, monitoring and power management system, not a cargo/radar level gauging product. This entry addresses that actual product and should be re-verified against the DNV TA certificate (TAA00003TY) before publishing. Class treats the alarm, monitoring and control system as part of the machinery automation survey scope - annual function testing of alarms, safety trips and redundancy/changeover arrangements is typically required, with records retained on board.
