Westinghouse provides balance of plant (BOP) engineering and component installation (E&CI) services that deliver engineering solutions across the entire plant, beyond traditional steam supply system services. From specialty consulting to integrated, comprehensive solutions for engineering projects, Westinghouse’s BOP E&CI services integrate customers’ needs and address them to optimize plant performance.


Westinghouse has extensive in-house design engineering capabilities and provides specialized welding, machining and component field installation. Westinghouse’s installation services’ capabilities are also complemented by its subsidiary, WesDyne International LLC, specializing in inspection services for the power industry with several locations in the United States and Sweden.

Westinghouse can:

Develop design change packages for component modifications, such as: condenser change-outs, moisture separator re-heater upgrades, feedwater heater replacements and digital instrumentation upgrades.

  • Provide BOP E&CI services for power uprate projects.
  • Perform heat exchanger inspections and maintenance, as well as turbine generator inspections on all major manufacturers’ equipment.
  • Provide motor, pump and valve diagnostics and refurbishments.
  • Perform integrated, comprehensive solutions for component
  • Respond to engineering, procurement and construction contracts for buried pipe solutions for infrastructure program management, including non-destructive examination, evaluation, design engineering for mitigation, installation project management and licensing.
  • Provide customers with on-site staff augmentation services.
  • Provide construction management and support services, including rigging, engineering, interference analysis, machining, welding and metrology.
  • Provide engineering services relating to electrical power equipment, thermo-hydraulic/heat balance and pipe stress analysis.
  • Perform asset management, BOP system analysis/optimization and scoping/feasibility studies.


Westinghouse is a proven and consistent supplier of nuclear, fossil and geothermal plant services, and its BOP E&CI services allow the customer to concentrate on operating the plant versus managing suppliers. Westinghouse has time-tested processes for project management, engineering, procurement and installation field services work. To simplify contracting activities, Westinghouse provides a wide range of services from simple engineering staff augmentation to integrated, comprehensive solutions for the project management of large, complex component replacements and plant-wide modification projects.
