Wärtsilä UNIC engine control system upgrade

Help ensure reliability and availability

The risk of unexpected shutdowns increases as electronic components in engine systems age. Over time, sourcing replacement components can become increasingly difficult, which increases both the severity and cost of shutdowns.

Why upgrade your WECS engine control system?

Upgrading to a modern system extends your engine’s lifetime, improves availability and performance, and ensures better support. A modern system also meets major class requirements and offers improved cyber security to prevent cyber incidents from affecting the engine.

    Solution

    The Wärtsilä Unified Controls (UNIC) system takes care of all engine control and monitoring functions for both newly built engines and as a retrofit for older Wärtsilä engines. It is an embedded engine management system that handles start/stop management, engine safety, fuel management and speed/load control as well as charge air, cooling and combustion. The Wärtsilä UNIC engine control system is a durable, all-inclusive automation system specially designed for the harsh environments in which engines operate.
