Installation of the new main engine with the SCR system. The works included the removal of the part of the old main engine cables and installation of the new cables to the extent necessary for the proper functioning of the engine. The new ABC engine control system has been integrated into Noris, existing, first generation remote control and monitoring system. Matching the signals between the two systems was possible thanks to the use of signal converters. Additionally, the SCR exhaust gas treatment system has been installed, connected and started.
