Migration Program to Upgrade Legacy Systems

Mark IV to Mark VIe Turbine Control Migration

We offer a Mark IV to Mark VIe migration program to upgrade these legacy GE control systems to modern technology with minimum downtime. Prefabricated bases with Mark VIe electronics are installed in the existing Mark IV cabinets and connected to the existing terminal boards with plug-in wire harnesses. Field terminations and turbine devices are retained to minimize Mark IV to Mark VIe installation time.
