Experience matters

Our field service and engineering teams are experienced and equipped to effectively collaborate with operators on a variety of maintenance scopes. Get to know some of them below.

Christian Arcari, Senior Engineer, Controls and Operability

From commissioning support and controls to upgrades, when it comes to the 501F turbine, there is nothing Christian hasn’t worked on.

Christian has dedicated seven years to heavy-duty gas turbines, specifically the Mitsubishi 501F, Siemens-Westinghouse 501F, Siemens V84/V94, GE 7FA and 7EA platforms. In the past, Christian has worked for Siemens Energy in the Operations and Maintenance group, focusing on technical support for the total plant (which included the gas turbine, steam turbine, and balance of plant). Additionally, he worked for PSM (Power Systems Mfg) where he served as the technical lead for the Monitoring and Diagnostics (M&D) center.

From commissioning support and controls to upgrades, when it comes to the Mitsubishi, Siemens, and now GE turbines, there is nothing Christian hasn’t worked on. He particularly enjoys troubleshooting complex operational issues, installing control system upgrades and commissioning new systems. During GE’s latest outage execution in Tuxpan, Mexico, he played a significant role in the commissioning of the first DLN-Pro combustor in a Mitsubishi 501F.

Christian is one cornerstone of the Cross-Fleet team and as such, he’s also responsible for ensuring knowledge transfer within the Cross-Fleet and Field Services team.

Stephen Ziegler, Lead Controls Engineer

Stephen has cultivated his professional experience through the execution of more than 50 outages in the US Navy and TVA.

Does the U.S. Navy Nuclear Power Program or Tennessee Valley Authority (TVA) ring a bell? These are just two of the many environments where Stephen has cultivated his professional experience throughout the execution of more than 50 outages. Stephen specializes in electrical engineering and has extensive knowledge on multiple platforms such as Mitsubishi Diasys Netmation, Emerson Ovation, Siemens Teleperm XP (TXP/SPPA-T2000) and Siemens SPPA-T3000—controls systems that are normally found on the Mitsubishi and Siemens/Westinghouse 501F and Siemens V (V84.3A2) machine gas turbine variants.

Stephen’s vast experience in the power industry spans simple and combined-cycle gas, nuclear, and coal power generation. He has worked as a consultant on controls and automation, and during his time at TVA he was the first controls engineer and specialist for an MHI 501F3 CCPP with the Mitsubishi Diasys Netmation control system. He also helped commission and maintained several gas plants spanning multiple OEM equipment including Siemens/Westinghouse, Mitsubishi, and GE.

Overall, he has 29 years of controls and automation experience and 16 years specifically dealing with the controls and tuning of the M501F and SW501F platforms. As part of the Cross-Fleet team, he leads the integration of GE hardware into non-GE controls; engineering modifications, instrumenting the controls system, updating all graphics and tuning the gas turbines. He’s the controls engineer professional that will upgrade your legacy MHI or Siemens unit to GE’s advanced four-stage DLN PRO combustion system and make it work seamlessly—all with an increased power output, improved efficiency, extended life, and better reliability.
