2015 Combined Cycle Users Group & Steam Turbine Users Group: Issue 2
|
|
|
|
 The Steam Turbine Users Group's (STUG) 2015 meeting, co-located with the Combined Cycle Users Group (CCUG) conference, August 24-27, in Orlando, offered the most comprehensive program for steam-turbine owner/operators in recent memory-one focusing on the specific information needs of O&M personnel. The agenda featured these three key elements:
-
-
Six-hour workshops conducted by each of the three principal OEMs: Siemens Energy, MD&A/Mitsubishi Hitachi Power Systems, and GE. They enabled users to "visit," via well-illustrated slides, modern shops and their capabilities, equipment and service offerings, and recent projects of interest involving inspection, overhaul, repair, and upgrade of steam turbines and generators. -

| OEMs inundate turbine users with details on products, services, procedures, upgrades, shop capabilities, experience |
The STUG steering committee and the three turbine OEMs put a great deal of effort into compiling information for the 2015 meeting that collectively amounts to what you might get in a college course over a semester. If you were at the conference, perhaps you missed portions of presentations of value to you. If you were unable to attend the meeting you're probably unaware of what was presented. more |
