The benefits of predictive maintenance for marine engines are clear. Not only do you get better safety and performance, you also mitigate the risk of costly failures and extend the life of your engine.
But many older marine engines don’t have the monitoring insights that are so critical to discovering and fixing small problems before they turn into big ones. They were commissioned before these sensor and reporting technologies were developed and as widespread as they are today.
Now, you can retrofit any four-stroke marine engine to significantly improve safety, performance and reliability. Our Multifunctional Monitoring System gives you real-time insight in the parameters that matter most to predictive maintenance.
Multiple monitoring functions – all in one place
Every four-stroke engine is different. That’s why we developed a modular sensor and monitoring solution that lets you decide which parameters matter most to your predictive maintenance needs.
Whether you choose one or all nine modules, your team will get the data-driven insight they need for early anomaly detection and corrective action. All in one user-friendly display panel. All in their choice of six languages.
Proven technology that works out of the box
MAN´s Multifunctional Monitoring System has logged thousands of engine hours worldwide. The hardware and software are fully developed, tested, and certified - and ready to implement on any four-stroke engine. And the convenient display gives your team real-time insights when and where they need them, in a language they understand.
MMS FOR SAFETY
