Journal Machining

We’ve had quite a run on Journal Machining this outage season, much like most outage seasons.  We’re working hard to make sure all of our customers can get their equipment back into good running condition and complete their outages on-time.  As these emergent repairs are discovered please give us a call, we have the equipment and personnel to machine most standard turbine rotor journals and collector rings – as well as provide many other types of on-site repairs.  Here are a couple of photos showing both the equipment set up on the journal, as well as the journal after final machining.

Keeping the Electricity Flowing

We have quite a few projects ongoing at the moment, even with current COVID-19 concerns.  Providing electricity to homes all across the country is vital to the well-being of the public, and it is our responsibility to continue on as we try to get through this together.  The men and women that are out in the field performing this work are making a sacrifice for all of us as the country continues to tighten restrictions on travel and access to everyday necessities.  We’d like to thank turbine maintenance personnel all across the World for what they are doing right now to keep electricity flowing – stay safe and healthy out there!

PSG Customers and Suppliers – Our COVID-19 Action Plan

PSG and our affiliated companies, Orbital Energy Services (OES), Turbine Generator Maintenance (TGM), and Airco Power Services, continues to closely monitor the COVID-19 situation to address concerns and issues that may affect the health and safety of our employees, customers, and suppliers. Like other organizations, PSG relies on guidance from the CDC and US Department of State related COVID-19 precautions. Communication with our partners remains a priority as the situation rapidly changes.  As such, PSG has taken action to address its own facilities, as well as those customer facilities at which PSG employees are working.

PSG is currently operating with the following precautions in place to limit exposure to the COVID-19 virus. Our employees, and through their interaction with customers and suppliers, have implemented these actions regardless of location:

  • Customer and supplier visits to PSG facilities must be business-critical and approved by the facility manager. As a precaution, body temperature of any person entering a PSG facility, employee or visitor, is checked and must be within CDC guidelines.
  • All travel unrelated to execution of business has been eliminated. All air travel must be approved by senior management directly reporting to the CEO. Our field teams are driving to customer job sites as much as possible and will comply with all customer-specific site protocols.
  • All employees returning from international travel are self-quarantined for 14 days at home to ensure wellness.
  • Where practical, office employees have the option to work from home to promote social distancing.
  • Web meetings and teleconferences are encouraged as an alternative to face-to-face meetings, both internally and externally.

PSG’s commitments to safety and service excellence remain our top priorities and our core values, and we will take the necessary steps to ensure the highest standards of both are at the forefront of everything we do.
