Frequently asked questions

Learn more about our Controls Lifecare Services

Do you have product support for Mark V control systems?

The Mark V system is not produced anymore, so new parts are not available.  GE Vernova does have limited refurbished parts available, as well as options for repairs and replacement exchange.  We also have OEM factory-trained field engineering resources for your service needs. In addition to ongoing support, an existing Mark V can be replaced in full with a new Mark VIe control. A Mark VIe control offers many advantages over the legacy Mark V control, including a distributed control architecture, reduced footprint, enhanced computing, and simpler product structure.

What training options are available around controls operation and maintenance?

GE Vernova has multiple training programs available, including in-person classes at one of our training facilities, or options for standard and custom training classes can be done onsite.   Course details and options can be found in our latest training catalog.

What are the recommended best practices for cybersecurity?

For cybersecurity, each plant has different needs based on equipment, location, policy, and risk profile.  It's a very difficult challenge to keep up with and get ahead of cybersecurity risks. We encourage all our customers to find a trusted partner that understands the control system and the network along with the different threat vectors to stay ahead of it as best as possible. Learn more about how GE Vernova can partner with you.

Does isolating a controls system for other controls in the plant provide good cybersecurity protection?

Control isolation is becoming less viable as a cybersecurity strategy, in part because there are other mechanisms used by infrastructure managers and adversaries alike to perform the necessary task of moving data into and out of islanded control system networks. These include the use of USB sticks and removable media to bring patches and updates into the control system environment and to move business data regarding production out to an otherwise unreachable business network. These mechanisms can carry viruses and malware without the knowledge of plant maintenance personnel. 

Unfortunately, one of the largest threats come from inside of the power plant, like a disgruntled employee or someone unintentionally connecting a phone or USB port with a virus. 

Beyond the risks associated with removable media, there are other potential issues with unexpected connectivity enabled by an adversary, malicious insider, or even an insider acting in good faith but incautiously. Even if wireless networks are forbidden, one of these kinds of actors can easily add wireless access points to the network by plugging it into an unused and unblocked network port. Such wireless access may even be accessible from outside the plant perimeter.

Can GE Vernova help me with my spare parts strategies?

We have several resources that can support your spare parts strategies. The first step is to understand which control systems you have, and where they are in their lifecycle. Our parts experts can help by performing a spare parts assessment of your existing spares to help ensure they are the latest revision and are still applicable for your control system. Recommendations can then be made for critical spare parts and recommended actions for your existing spare parts. Please see our parts fact sheet for more information or contact us at [email protected].

What are GE Vernova’s controls preventive maintenance recommendations for digital control systems?

We recommend developing a maintenance program to address common failure areas.  A good source to start with is GEH-6721 volume 2 , which provides instructions on Mark VIe maintenance including panel cleaning, cooling fans check, maintaining temperature, terminal tightening, air filters cleaning, review of Mark VIe diagnostics logs and execution of corrective actions. Customers should also consider doing an obsolescence evaluation to understand the parts requirement. In addition, we recommend that all applicable TILs be implemented, including maintenance TILs.

  • The GE Vernova team is also developing a dashboard for our customers to get visibility on their hardware and software life cycles, as well as their software  vulnerability status. This dashboard will give customers visibility of their hardware life cycle status and software updates needed, both from obsolescence and vulnerability perspective, which will help them plan for maintenance actions.
  • From a cybersecurity perspective, if a network intrusion detection system installed, then it is also recommended to look for syslog/SIEM messages to understand if there are any cyber-attacks being attempted. In addition, vulnerabilities related to Windows OS, tool boxST, QNX OS, CISCO NW switch IOS, and fortigate OS, are updated in GE Vernova cybersecurity portal. These notifications also include recommendations for software updates. So, we recommend you look out for notifications and install software updates/patches as soon as that is available.

These are our basic recommendation, but they are not comprehensive one, so if you need GE Vernova’s support on preventive maintenance, please contact us. For a comprehensive list of GE Vernova’s Controls Lifecare Services (CLS), please refer to the CLS factsheet
