In-Shop Repair ServicesOne Standard for Safety, Quality & Repairs – Across North America

Leveraging IPS Quality Leadership Across North America.Working closely with wind power OEMs and wind farm owners and operators, IPS relies on innovative in-shop and up-tower processes to increase reliability and minimize downtime.

The IPS service center in Litchfield, MN, leads and manages all IPS wind power initiatives, certifying other IPS regional service centers for wind power quality and repair procedures. All IPS regional service centers offer an ISO-compliant Quality Management System, with quality coordinators at every location to support the integration of IPS quality and repair standards.

No matter which IPS service center handles your wind power services, you can count on one standard of excellence for safety, quality and repairs—across North America.

IPS continues to define and document best practices and OEM repair standards,

drawing on long-established relationships with wind power customers and

Safety FirstIPS maintains a strong corporate commitment to a safe work environment, with a dedicated Health, Safety and Environmental Manager overseeing one safety standard for all locations across North America. Our policy is to exceed all federal and state safety regulations—our Experience Modification Ratio (EMR) is well below the industry average.

Up-tower safety training includes:

• Fall protection • Blood Born Pathogens • Tractel • Fire Extiguisher • NFPA 70E • CPR and First Aid training • Lockout Tagout (LOTO) • OSHA 10

Industry-leading experience and capabilitiesIPS leads the industry in up-tower services. We’ve done thousands of bearing and slip ring replacements, and offer a full range of predictive and preventive maintenance services. Our technicians have developed innovative skills and technologies to keep the work up-tower—we’re experienced at moving heavyweight couplings, end bells, slip rings and doing precision machine work inside the nacelle. Our experience covers virtually every brand and size of wind turbine and our capabilities include the following:

Our objective is to do as much as we can up-tower, safely and efficiently, to minimize downtime and lost revenue.

Fast mobilization and minimal downtime on the following:• Gearbox flush and oil change

• Up-tower bearing changes

• Coupling replacement

• Hub slip ring tube seal replacement

• Torque services

• Crane services

• 24/7 emergency repairs

• Bore scoping

• Vibration and modal analysis

• Laser alignment

• Thermography

Coupling installations

Our technicians are trained for generator replacements. In addition, our generator unit exchange program cuts downtime and crane costs.

North American CoverageOne of the advantages of our North

American footprint is rapid response times

for service. We have fully equipped field

service trucks located across the country

for rapid response, on-site and up-tower. In

addition, each of our regional service centers

has its own fleet of trucks for on-site pickup

and delivery, working closely with site

supervisors on scheduling times to meet the

crane at the tower (saving downtime and

extra handling of the generators).

Pre end-of-warranty inspections to detect and address:• Imbalance

• Misalignment

• Mechanical looseness

• Rotor eccentricity

• Shaft bends

• Lubrication condition

• Bearings

• Gears and gearbox problems

• Generator faults

• Rubbing

• Natural frequency and resonance

Bearing changeouts Brush holder upgrades

Slip ring turning Thermography MCE testing

Generator Exchange, Remanufacture and Storage ProgramIPS maintains a wide range

of spare generators in various

sizes and brands, to eliminate

unnecessary capital invesment

on your part and reduce crane

costs. With regional service

centers and strategically located

warehouses in Canada and the

United States, we can exchange

and remanufacture failed units

quickly and cost-effectively, to

minimize downtime and help

you keep your run-time commitments. IPS also offers storage programs to manage gen-

erators for leading wind farms and OEMs across North America—we’d be pleased to talk

with you about how we could increase your generator reliability and overall profitability.

Our in-house CNC facility manufactures

low- and high-volume precision machined

parts for the wind industry. This allows us to

meet the delivery and quality expectations

of our customers.

Our CNC capabilities include:

CNC Precision Parts Manufacturing

• Shafts up to 22” diameter and 80” long

• Milling up to 20” x 40” plate

• Drilling and tapping of holes

• Milling of flats and hex parts

• Machining keyways

• Cutting multiple parts and sizes up to 16” diameter

• Digital bore gauges

• CADCAM 3D drawingsLine Reactor Exchange ProgramIPS engineers applied their expertise in rewind technologies, insulation systems and

equipment design to significantly upgrade the reliability of existing wind turbine line

reactors. Our approach to remanufacturing line reactors targets problems instead of

symptoms, drilling down for root cause analysis and setting the stage for definitive

solutions. Our proprietary line reactor remanufacture process and design upgrades

provide superior insulation dielectrics and heat transfer throughout the inductors. The

resulting benefits are higher breakdown

voltages, increased efficiency and extended

service life.
