HRS specializes in field machining. Including: line boring, embed machining, facing, and custom in-place repairs. When the outage scope grows, our crews can support the full mechanical side of the unit, including disassembly, reassembly, bearing refurbishment, cavitation repair, crack repair, weld overlay, component fabrication, draft tube platforms, alignment, and general turbine repair. From planned outages to mid-project discoveries, HRS brings the crew, tooling, shop support, and field experience needed to keep the mechanical work moving.

What we service
HRS supports the mechanical side of hydro unit outages, from field machining runner repair to full unit disassembly, reassembly, and component restoration. Each capability connects the issue, the field method, and the documentation your outage team can use.
Cavitation repair, crack repair, weld build-up, profile restoration, blending, NDE support, and repair documentation for hydro turbine runners.
Organized mechanical teardown, component removal, inspection access, fit-up, alignment assistance, and reassembly for turbine units and major mechanical components.
In-place machining for embedded components, sole plates, bearings, discharge rings, stay rings, head covers, bottom rings, and shaft-related components. HRS supports line boring, facing, drilling, tapping, fit restoration, and custom machining when components cannot practically leave the site.
Experience
Hydro repair is risk work. Each card covers a service line HRS has supported, the plants and owner groups involved, and the kind of outage work the crew has already handled. Tap a card to see the full reference list.
Confidential Utility
Restore discharge ring geometry without shipping the component off site.
We've been in enough powerhouses to know that the people signing the purchase order don't care about slogans. They care that the documentation lines up, the crew shows up, and the unit comes back online. Here's how we deliver on all three.
Every job is scoped the same way: evaluate the situation, devise the most effective solution, and execute it for the shortest possible downtime. That's the whole philosophy. It's why utilities call us for the tricky parts of an outage their primary vendor won't quote.

TVA at Raccoon Mountain, Boone, Chickamauga, Hiwassee, Kentucky, and Watts Bar. USACE at Bonneville, Lower Monumental, Little Goose, West Point, and Harry S. Truman. BC Hydro at G.M. Shrum and Revelstoke. DWR at Oroville. Bath County. Grand Coulee. Ludington. If it generates hydroelectric power, we've likely been inside it.
Major partners:

Our supervisors bring a combined over thirty years of turbine repair experience. The craft labor pool averages 5 years of welding and machining. These are the people who show up on your dam, not a rotating subcontractor, not someone pulled from a labor broker.

Field Operations
Hydro powerhouse repair is high-risk, critical-path work. Confined spaces, heavy overhead lifting, stainless steel welding, and high-voltage areas leave no room for error. We do not field rotate subcontractors or uncertified crews. We do not hire from labor brokers. Every member deployed to your dam holds these active, verified certifications.
All HRS personnel are trained personally by experienced management. Our supervisors oversee hands-on safety checkouts and site-specific hazard reviews before a single crew member steps onto the powerhouse floor.
Universal foundation in high-risk construction safety, hazard recognition, PPE protocols, and electrical safety.
Mandatory certification for entering penstocks, scroll cases, draft tubes, and runner hubs. Includes atmospheric testing and rescue plans.
Advanced safety harness, anchor calculation, and scaffolding safety for vertical shaft and high-elevation rotor rigging.
Critical path lift-plan execution for handling turbine runners, headcovers, and shafts weighing up to hundreds of tons.
Hazard identification and respiratory safety protocols during stainless steel welding, runner overlay, and metal grinding.
Zero-energy state verification protocols to isolate hydraulic, electrical, and pneumatic power prior to machinery entry.
Outage-ready emergency first response, automated external defibrillator (AED) utilization, and trauma stabilization training.
HRS stays small on purpose. The people listed here are tied to the field work, estimating, scheduling, documentation, and owner coordination that keep hydro repair jobs moving.
Justin Parker
Owner / President
20 years experience
Dam work began straight after high school graduation in 2006. After working for others & feeling unheard, Justin created HRS in 2016 in order to better utilize the knowledge overflowing from learned experiences.

Logan Moudy
Project Manager
8 years experience
Logan joined HRS in 2018 during one of the company’s longest outage projects. His background in field supervision and project coordination helps keep outage work organized, documented, and moving.
Specialty welders, machinists, and turbine techs. Travel pay, real benefits, and a shop where the senior crew has names and tenure. If you've been in a unit at 3 a.m. in February, we'd like to talk.
