Repair the electronics behind the system.
Marine automation systems depend on electronic boards that are often difficult or expensive to replace. We diagnose and repair marine automation electronics where practical, helping extend equipment life and reduce unnecessary replacement.
DIAGNOSTICS
When replacement is not the only answer.
A failed electronic board can stop a much larger automation system from operating. For older vessels, the original replacement may be obsolete, unavailable or subject to long lead times.
Component-level diagnosis can provide another option. Instead of immediately replacing an entire assembly, the electronic board can first be inspected, diagnosed and assessed for repair feasibility.
From fault diagnosis to functional testing.
Our approach combines electronics troubleshooting with practical marine automation experience. The objective is not simply to replace a component, but to understand why the board failed and verify its operation after repair.
Component-Level Diagnostics
Inspection and troubleshooting of electronic circuits, components and failure points to identify the source of the fault.
Power Supply Circuits
Diagnosis of power input stages, regulators, protection circuits and power-related failures affecting control electronics.
I/O & Interface Boards
Investigation of digital, analogue and communication interface problems within automation and control boards.
Controller Electronics
Assessment of controller and processor-related electronic faults where board-level diagnosis is technically feasible.
Driver & Output Circuits
Troubleshooting of relay, transistor, driver and output stages associated with control and automation functions.
Communication Interfaces
Diagnosis of electronic interface problems affecting communication between automation equipment and connected systems.
Electronics used throughout the vessel.
Marine control electronics rarely exists as an isolated component. It forms part of a larger automation architecture involving controllers, I/O, power systems, instrumentation and communication.
PLC & I/O Electronics
Controller modules, digital and analogue I/O electronics, interface modules and related control boards.
PMS & Generator Electronics
Electronic assemblies associated with generator control, power management and synchronisation systems.
HMI & Control Interfaces
Control interface electronics and supporting hardware where repair assessment is technically appropriate.
Communication Electronics
Interface and communication boards used between automation controllers and third-party equipment.
Obsolete Equipment
Older automation electronics where replacement components may no longer be readily available.
Custom & Special-Purpose Boards
Application-specific electronics can be assessed based on board condition, available documentation and test requirements.
Diagnose first. Repair with evidence.
A reliable repair starts with understanding the failure. Our process is structured around diagnosis, repair feasibility and verification rather than replacing components blindly.
Initial Inspection
Visual inspection, board condition assessment and collection of available fault information and history.
Fault Diagnosis
Electrical measurements and component-level troubleshooting to identify the suspected failure area.
Repair Assessment
Determine whether the board can be repaired safely and economically based on its condition and available information.
Component Repair
Repair or replacement of failed components and restoration of affected circuit sections where practical.
Functional Verification
Post-repair checks and functional testing appropriate to the available equipment, documentation and application.
The right solution depends on the equipment.
Extend the life of existing equipment.
Repair can be a practical option when the equipment is obsolete, difficult to source, expensive to replace or closely integrated with the vessel’s existing system.
Where technically feasible, repairing the original board can reduce replacement cost, lead time and integration work.
Modernise when repair is no longer practical.
If a board is beyond economical repair, lacks critical components or presents an unacceptable reliability risk, replacement or system modernization may be the better solution.
In those cases, Doksal can support the wider automation retrofit and integration process.
Electronics repair with the system in mind.
A PCB on a vessel is rarely just a PCB. It may be part of an IAS, PMS, propulsion control system, generator controller, alarm system or communication architecture.
Understanding how the board interacts with the wider automation system helps us approach the fault from both the electronics and control-system perspective.

Repair assessment for obsolete automation equipment
Have a failed control board that is difficult to replace?
Tell us what equipment the board belongs to, what fault has been observed and, if available, provide the manufacturer, model and board reference. We can assess the repair possibilities and determine the most practical next step.
