From a failed control module to a successfully commissioned PLC solution.
AUTOMATOS KOSMOS 4U completed an onboard control system retrofit on a Wärtsilä engine, replacing a faulty MCM11 module that could not be repaired with a purpose-engineered PLC solution.
With the vessel in service and a limited intervention window, our specialist engineers and technicians carried out the assessment, programming, electrical integration and commissioning directly onboard.
⚓ DIAGNOSIS & SIGNAL MAPPING
Our team investigated the fault, confirmed the condition of the MCM11 module and documented the connected field signals and control interfaces. This provided the engineering basis for developing the replacement control logic.
⚓ PLC ENGINEERING & ELECTRICAL INTEGRATION
The work included:
✅ Recording and mapping the existing input and output signals.
✅ Developing the PLC application for the required control functions.
✅ Preparing and completing the electrical connections and wiring modifications.
✅ Integrating the new controller with the existing engine installation.
✅ Checking signal response and operating sequences.
✅ Completing onboard functional testing, adjustments and commissioning.
✅ Preparing the project’s electrical and technical documentation.
⚓ TESTED, COMMISSIONED & HANDED OVER
Following successful functional testing and commissioning, the upgraded system was handed over in working order.
The project demonstrates our ability to deliver practical retrofit solutions under demanding onboard conditions, combining field troubleshooting, control engineering and hands-on installation within a short timeframe.
Watch our team take the project from diagnosis and programming through to integration and engine operation.
