Find the fault.
Understand the cause.
Restore control.
Marine automation faults rarely have a single obvious cause. We diagnose control, communication, software, instrumentation and hardware problems systematically — helping vessels return to reliable operation as quickly as possible.
Troubleshooting is more than
finding a component that failed.
A failed alarm, unstable communication link or unexpected control behaviour may be the result of a much deeper problem. We analyse the complete control chain to identify the actual source of the fault rather than simply replacing components until the problem disappears.
Our troubleshooting work can be performed during commissioning, onboard service visits, retrofit projects or as part of remote technical support.
From field signals to
vessel-wide control systems.
Our troubleshooting capability covers the complete automation architecture of a vessel.
PLC & Control Logic
Diagnosis of PLC programs, control sequences, interlocks, permissives, timers, state machines and unexpected machine behaviour.
HMI & SCADA
Investigation of missing data, incorrect values, alarm behaviour, visualization problems and operator interface issues.
Communication Faults
Diagnosis of Modbus, CAN, Ethernet, serial communication and network-related failures between control system components.
I/O & Instrumentation
Signal tracing for digital and analogue I/O, transmitters, sensors, relays and field devices.
Alarm & Interlock Problems
Investigation of false alarms, missing alarms, alarm logic, shutdown conditions and interlock behaviour.
Integrated Systems
Troubleshooting across IAS, PMS and third-party equipment where multiple systems interact.
When the problem is inside the board.
Not every automation fault requires replacing an expensive electronic module. Where practical, we can investigate and repair electronic control boards and PCB assemblies used within marine automation systems.
Board-level diagnostics can help reduce unnecessary replacement costs and minimise downtime when obsolete or difficult-to-source modules are involved.
- Electronic control board diagnostics
- Power supply and protection circuit faults
- Component-level fault investigation
- Connector, relay and signal path problems
- Repair assessment for obsolete automation modules
A structured approach to complex faults.
The objective is not simply to restore operation temporarily. We aim to understand what happened, why it happened and what should be done to prevent the same failure from returning.
Understand the Symptoms
Review alarms, operator observations, system history and the conditions under which the fault occurs.
Trace the System
Follow the signal, control command or communication path through the relevant system components.
Identify the Root Cause
Separate the actual cause from secondary symptoms and determine whether the issue is hardware, software, configuration or integration related.
Restore & Verify
Apply the required repair or modification and verify correct operation under realistic operating conditions.
Troubleshooting across the
automation architecture.
Integrated Automation
Machinery monitoring, alarm systems, control functions, remote I/O, PLCs and operator stations.
Power Management
Generator control, synchronisation, load sharing, breaker logic and power management functions.
Control & Monitoring
PLC applications, visualization systems, SCADA, alarm management and industrial communication.
System Integration
Investigation of interfaces and communication between marine automation systems and third-party equipment.
