Millwright Services for STO Events

When the outage window opens, there’s no time for surprises.

Cornerstone helps your team prepare before the shutdown and execute efficiently once work begins. Our pre-outage assessments can identify developing equipment issues, help define and prioritize the scope, and give your team a clearer work plan before the clock starts.

When it’s time to execute, our experienced millwrights provide precision rotating equipment repair and maintenance with 24/7 support and a focus on safety, quality and getting your equipment back online on schedule.

Before your outage, we can help with:

  • Vibration analysis & condition monitoring to identify potential equipment issues before the shutdown
  • Pre-outage equipment assessments to better understand equipment condition and anticipated repair needs
  • Scope planning & prioritization to help determine what needs attention during the available outage window
  • Ongoing reliability support to track equipment condition between outages and help your team prepare for the next one

Whether you need support for a single shutdown or a long-term rotating equipment partner, Cornerstone can scale our involvement around your facility’s needs.
