501F and G users meet together—again – Combined Cycle Journal

501F and G users meet together—again


Owner/operators of Siemens Energy/Westinghouse Electric Corp 501F and 501G gas turbines co-locate at the Peppermill Resort and Spa in Reno, Nev, for their 2023 conferences, Sunday Feb 19 through noon Thursday Feb 23. The last time these two organizations shared the same in-person venue was in February 2020 at the Hilton West Palm Beach, about a month before the pandemic changed things.

Sunday’s program features social events for all attendees. The agenda for Monday—including a safety roundtable, vendor presentations, and vendor fair—also is for both the 501F and 501G Users Groups. The organizations meet independently on Tuesday, Wednesday, and Thursday for technical presentations by users, services providers, and OEMs.

CCJ’s special publication for the 501F/G event, sponsored by Arnold Group, begins with the Monday program—including the Vendorama schedule and Exhibit Hall floorplan, the latter with participants and booth numbers identified. Bear in mind that some of the information may have changed since it was provided to the editors on January 23 to meet the Journal’s printing schedule.

Sections specific to the F and G programs come next, along with summaries of presentations from previous meetings to bring attendees up to date on topics of importance they may have overlooked during the pandemic years.

Monday agenda for all users

The meeting gets underway after breakfast at 8 a.m. with welcomes by the user-group chairs and introductions. Safety roundtable is next, focusing on human performance, led by a well-respected subject-matter expert. The Vendorama program gets underway at 10:20 following a tutorial on the 501F website and the morning break.

Note that all conference activities associated with the 501F and 501G Users Groups, including meals, are in the Tuscany Ballroom, which can be divided, as necessary, in up to a dozen individual rooms (Tuscany 1, 2, 3, etc). The room numbers for specific activities (such as those for the Vendorama presentations) are not identified here because they likely will change prior to the meeting. Current information is available in the conference registration area.

The 35 half-hour Vendorama presentations are arranged in seven sessions, with five presentations conducted in parallel during each session. Here are the topics and companies involved:
