myNORIS Refit for Wärtsilä WECS 2000


Act now and replace your old WECS 2000

The Wärtsilä Engine Control System 2000 (WECS 2000) is a control system for Diesel engines and generators on ships. The original system consists of two bus lines, numerous electronic components in the central control unit and several data acquisition units all around the engine.

All that is replaced by a simple design with only one touchscreen display, one I/O-block and one independent safety system — SIMPLE, FAST, STRAIGHTFORWARD.

Our Refit solution

The original engine build-on control unit and the screen will be removed and replaced by a local control panel while the new control unit is built in separate cabinet. The local data acquisition units (SDU, DCU) will be replaced by simple junction boxes, which enables you to keep the original sensors. New cables are laid between the junction boxes, the central unit and the local control panel.
