Global market valuation was derived through service contract value mapping and installed base analysis. The methodology included:
Identification of 50+ key service providers and OEMs across North America, Europe, Asia-Pacific, Middle East & Africa, and Latin America
Service mapping across maintenance (routine/periodic), repair (minor/major), overhaul (minor/major), and spare parts supply categories
Turbine type classification across heavy-duty (>100 MW), aeroderivative (aviation-derived), and industrial (mechanical drive/cogeneration) segments
Analysis of reported and modeled annual service revenues specific to gas turbine maintenance portfolios, including Long-Term Service Agreements (LTSAs) and ad-hoc repair contracts
Coverage of service providers and OEMs representing 75-80% of global market share in 2024
Extrapolation using bottom-up (installed base × maintenance cost per fired hour × annual operating hours by country) and top-down (service provider revenue validation) approaches to derive segment-specific valuations for OEM vs. independent service provider channels, heavy-duty vs. aeroderivative fleets, and power generation vs. oil & gas end-use applications
