Wood Group Pratt & Whitney

What Wood Group Pratt & Whitney does

Wood Group Pratt & Whitney (WGPW) is a privately held industrial turbine services company headquartered in Bloomfield, Connecticut. The firm specializes in the overhaul, repair, and lifecycle support of Pratt & Whitney aero derivative gas turbines, specifically the GG3, GG4, and GG8 gas generators and FT4 free turbines. As of January 2026, WGPW holds the exclusive global OEM license for GG/FT4 production, effectively making it the sole authorized manufacturer and authorized service provider for these engine families following Pratt & Whitney's exit from direct FT4 support.

The company's core capabilities are delivered from a dedicated Bloomfield facility featuring a four-bay disassembly line and four-bay reassembly line, an in-house machine shop, CMM and non-destructive testing (FPI and MPI) capabilities, computerized rotor balancing, a fully equipped engine test facility for GG3/GG4/FT4, and an on-campus metallurgy laboratory. WGPW also services Hamilton Standard fuel controls (SPC2A, 2B, 2D, 2E, H models) and provides global on-site field services through Technical Field Advisors for major field maintenance, hot section inspection, annual unit audits, vibration and balancing work, and mechanical services. The firm maintains an FT4 spare parts inventory valued at well over $40 million, including Pratt & Whitney's entire transferred FT4 inventory, and operates a lease/rotable equipment program to minimize customer downtime.

WGPW generates revenue primarily through professional services (overhaul and repair contracts, fuel controls repair and calibration, field service), hardware sales (FT4 spare parts), and managed services (gas turbine lease assets and module exchange programs). Pricing is quote-based on multi-year contracts targeting enterprise operators of industrial gas turbines in power generation and mechanical drive applications. Customer acquisition relies on direct enterprise field sales, industry reputation, and technical expertise rather than digital marketing. The company holds ISO 9001 certification and is privately held with no disclosed institutional investors or parent company.
