Keep Your Equipment Running Longer
ASKO offers both minor and major overhaul services to support the operations of steam turbines, rotating equipment, mechanical equipment, and static equipment.


An Overhaul You Can Depend On
Having a regular overhauling maintenance schedule—and a maintenance partner you can depend on—is crucial for reliable equipment performance. Working with ASKO for your minor and major overhauling helps avoid higher costs down the line, keeps equipment running well, prevents safety hazards, and overall extends the lifespan of equipment.
Depending on operational conditions, application usages, and the environment, equipment degradation can also occur faster than expected. Having ASKO on standby means you’ll have a responsive maintenance partner ready to address any urgent issues with your critical machinery.

We Support Scheduled and Unplanned Maintenance
We strategically schedule overhauls during our customers’ planned shutdowns, Turnaround Outage and Revamps (TORs), and yearly inspections to minimize disruptions and optimize equipment operations. We also work closely with customers to determine the most efficient combination of on-site and/or in-workshop overhauling wherever possible.
In the case of emergency overhauling, we can get your equipment back up and running as soon as possible thanks to our expert field engineers and a fully-equipped workshop. The ASKO field engineering team can be at your facility within 24 hours of your urgent request to assess, develop, and implement an overhauling plan.
Along with repairs and reconditioning, we provide local re-engineering and reverse engineering services to replace custom parts faster than ordering new ones. All of our manufactured spare parts come with a general warranty for your complete confidence. Additional 4,000 hour/crop year, service maintenance, and fieldwork warranties are also available.

ASKO’s Non-Destructive Testing Capabilities
ASKO uses non-destructive testing (NDT) to gain the best possible understanding of your equipment’s health without compromising its integrity. Our engineering team can perform spectrum vibration analysis (SVT), ultrasonic testing (UT), liquid penetration testing (PT), magnetic particle testing (MT), surface roughness testing, and surface hardness testing.
If NDT determines that servicing is required, ASKO is able to provide all required maintenance, including oil flushing, laser alignment, field balancing, and more. See our maintenance page for more information.

Our Commitment to Quality & Safety
At ASKO we take the quality of our work seriously, which is why we adhere to globally-recognized standards for quality management systems (QMS). We’re certified with UKAS Quality Management Systems ISO 9001:2015 for the manufacture of steam turbine parts, installation and service maintenance for steam turbines, and trading of steam turbine parts and accessories. Organizations with ISO 9001 have “put in place effective processes and trained staff to deliver flawless products or services time after time” (ISO.org), and ASKO is no exception.
