Inspector Detail

▸

Common issues

Obsolescence - spare parts increasingly scarce as the system is phased out by the manufacturer
Control panel/lever unit wear causing erratic commands
PLC/control card failures with no direct modern replacement
Communication faults between bridge, ECR and engine control cabinets
Battery backup degradation on control cabinets
Software incompatibility with newer engine ECU generations

Inspection checklist

Test bridge-to-engine control transfer sequence (bridge/ECR/local)
Verify telegraph/order indication agreement at all control stations
Check emergency stop and shutdown override functions
Inspect control cabinet wiring and terminals for corrosion
Test backup power supply and automatic changeover
Verify alarm printer/logging function if fitted
Check control lever/handle mechanical function and feedback

Service intervals

Function test of control transfer and telegraph systems	at each survey, typically annually
Backup battery replacement	typically every 3-5 years
Control cabinet cleaning and inspection	annually

Critical spares

Control lever/handle unit
Interface/communication card (system discontinued - source from manufacturer or certified reseller while stock remains)
Backup battery packs
Indicator/telegraph repeater unit

Safety

Loss of propulsion control if failover between control stations has not been verified
Electrical hazard inside control cabinets
Risk of uncommanded engine response from degraded control cards - increase test frequency given the system's end-of-life status

Class survey

Class checks that propulsion control and telegraph functions operate correctly across all control stations and that local/fallback control is available; given the system's discontinued status, surveyors may ask for a spares/obsolescence management plan.

Estimated lifetime: As a discontinued electronic propulsion control system, service life is now limited more by spares availability than by wear; plan for replacement or retrofit once critical spares (control cards, interface units) become unobtainable.
