A three-year, multi-outage environmental retrofit at one of the nation’s largest coal-fired power plants—executed through large-scale preassembly, precision crane planning, and sustained craft deployment totaling more than 3 million manhours with elite safety performance
Project Details
Baghouse & Emissions Systems (Preassembly + Installation)
Preassembly and installation of two (2) Pulse Jet Fabric Filter Baghouses, including:
Hoppers
Compartments
Structural steel framing
Ductwork and transitions
Piping systems
Sheeting and plate work
Performed ground-level modular preassembly to reduce outage duration and improve safety
Executed retrofit installation into existing plant infrastructure during scheduled outages
Completed touch-up painting, pipe supports, and finish work as part of final integration
Electrical & Mechanical Integration
Installation of:
Electrical conduit
Wire and terminations
Connections and transformers
Coordinated electrical and mechanical tie-ins to align with outage windows
Integrated new systems without interrupting ongoing plant operations
Precipitator & Air Heater Scope
Rebuilt two (2) existing precipitators, including:
Internals
Demolition of existing components
Installation of new engineered systems
New penthouse structures
Completed full air heater rebuild, including:
Hub
Gearbox
Baskets
Sector plates
Seals
Performed all work during planned outages, maintaining strict schedule control
Execution Strategy & Logistics
Work performed inside a fully operational, large-scale power-generation facility
Planned and executed multiple crane paths across numerous plant areas
Utilized approximately 20 cranes at peak activity
Included numerous engineered critical lifts
Leveraged NSC craft forces across three consecutive outage years
When peak manpower levels were constrained, NSC personnel were strategically re-deployed to maintain schedule and continuity
