2015 Combined Cycle Users Group & Steam Turbine Users Group: Issue 2

Steam-turbine users urged to consider the STUG annual meeting must attend

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:

Presentations by more than a half dozen users on projects offering valuable learning experiences for colleagues-including lessons learned and best practices.
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.
Presentations by third-party equipment and services providers on a dozen topics selected by the steering committee for their high level of interest to attendees. more

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
