Power Plant Maintenance & Millwright Servicesin Northwest Indiana & Chicagoland

What does SSI do for power plants?

We keep the rotating equipment, piping and auxiliary systems in power plants running between outages and help get outage work done on time. Our crews handle equipment rebuilds, pipe welding, laser alignment, fan balancing, preventive maintenance and 24/7 emergency repair across Northwest Indiana and Chicagoland.

Downtime in power generation has serious consequences, so reliability comes first. Our team has worked with turbines, boilers and the equipment that supports them. We focus on the pumps, fans, drives and piping that most often cause forced outages.

Which power plant equipment do you work on?

We work on the auxiliary and balance-of-plant equipment that keeps a unit online. That is where most of the wear happens and where a millwright and fabrication contractor adds the most value.

Equipment	Common problem	What we do
Draft fans and blowers	Vibration, imbalance, bearing failure	Fan balancing and alignment
Pumps	Seal leaks, bearing and impeller wear	Pump rebuilds
Gearboxes and drives	Heat, noise, gear wear	Gearbox rebuilds
Coupled drives	Misalignment, coupling wear	Laser alignment
Piping and supports	Erosion, cracking, leaks	Welding and pipe fabrication
Dust and ash systems	Wear, leaks, airflow loss	Baghouse and dust collection

Do you work on equipment around turbines and boilers?

Yes. Our team has experience with turbines, boilers and the equipment that supports them. On those systems, we focus on the work a millwright and fabrication crew does best: the pumps, fans, drives, piping, supports and platforms around the main equipment.

That includes rebuilding and aligning the pumps and motors that serve the unit, balancing draft fans, welding and repairing piping and supports, and fabricating access platforms and structural steel. When an original part is obsolete, our machine shop can reverse-engineer and machine a replacement so the unit isn’t waiting on a long lead time.

How do you support planned outages?

We support outages by planning early and doing as much as possible in the shop. Before the unit comes down, we walk the job with your team, list the equipment to rebuild, and stage parts and pipe spools. During the outage, our crews work to your schedule.

That planning keeps the outage on track. Our crews know what they’re walking into, parts are already on hand, and the equipment that comes back online has been aligned and checked.

How do you prevent problems between outages?

Our preventive maintenance program catches wear before it forces a shutdown. Typical work includes:

• vibration checks on fans, pumps and drives;
• laser alignment after any motor, coupling or bearing change;
• fan balancing when vibration rises;
• inspections of piping, supports and dust collection equipment;
• rebuild planning so worn units are scheduled into the next outage.

What about safety at power plants?

Safety is part of how every job is planned. We are an ISNetworld member contractor and Avetta prequalified. Every job starts with a job hazard analysis (JHA), and our crews work under lockout/tagout, confined space, hot work and fall protection programs. We follow your plant’s permits and procedures on top of our own. See our safety page.

Why do power plants call SSI?

Power plants call us because one crew can rebuild, weld, align, balance and fabricate. Fewer contractors on site means simpler coordination and a faster restart. When something fails between outages, call (219) 386-1506 any time or visit our emergency repair page. When downtime isn’t an option, we’re ready.
