Autonomous, AI-based, engine health monitoring system

IConIC enables marine systems to be operated and maintained at optimum levels, reducing emissions and fuel consumption, and avoiding expensive downtime caused by unexpected engine faults.

Easily retrofittable and using non-invasive sensors, IConIC uses Artificial Intelligence to learn what a healthy system looks like in a specific environment and then accurately monitors its health in real time to predict future faults, long before any other form of health monitoring, giving operators the insight required to determine the best possible maintenance strategy.

The IConIC advantage

IConIC chart of engine failure advantage AI

IConIC resolves the three key issues faced by traditional condition
monitoring systems

  • By using sophisticated signal processing and advanced machine learning, IConIC provides significantly earlier indication of impending fault
    conditions than any other detection method
  • With high-frequency sampling on each cylinder, IConIC provides more granularity, allowing for deeper fault diagnosis and analysis
  • Rather than using equipment manufacturers published information, IConIC develops its baseline health data from the actual engine it is monitoring, taking into account its age and local environment

IConIC provides earlier indication of impending fault conditions or performance degradation than any other detection technique.
