Control-system support
Control engineering for gas turbines.
Focused support for control-system reliability, recurring faults, obsolete hardware and site-specific improvement work—without extending beyond the systems and equipment we know.
01 / MAINTENANCE
Diagnostics & fault recovery
Health assessment, alarm and event review, I/O and network troubleshooting, configuration recovery and targeted field support for Mark control systems.
View maintenance scope ↗02 / OPTIMIZATIONSystem improvement & modernization
Site-specific engineering for grounding, communication paths, HMI, historian and control-network modernization.
Explore project scopes ↗03 / COMPATIBILITYCritical controls & parts
Component identification, cross-platform compatibility and supply support for control boards, instruments, HMI hardware, networks and power modules.
Search parts ↗Platform focus
Work from the operating symptom back to its control layer.
A trip, unstable signal, communication fault or obsolete part is rarely isolated to one component. GGP reviews the field device, I/O path, logic, network and operator layer as one working system.
