2014 Siemens 501F and 501G Users Groups: Issue 2

501G users expend considerable discussion time on non-engine issues

The 501G Users Group is small by industry standards: only 24 engines at a dozen sites in the US and one in Mexico. But the organization's size, capable leadership, and collaborative nature allow it to think and act as a unit-a SWAT team of sorts-facilitating problem-solving at the deck-plates level and with the OEM. There's not much turnover in the top positions at G facilities, at least compared to the industry at large, which means most attendees are familiar with the other participants and their plants. This makes for presentation efficiency and minimal repetition conference to conference. In effect, each meeting (there are two annually) picks up where the previous one ended. more 

What non-OEM equipment/services providers told 501F&G users (Part 2 of 2)

The 501F and 501G Users Groups integrate more suppliers into their formal presentation program than any other user organization serving gas-turbine owner/operators. On Day One of the 2014 meeting at the Westin Mission Hills Resort & Spa in Rancho Mirage, Calif, February 16-20, the Vendorama agenda featured 42 presentations-six conducted in parallel in each of seven time slots. Below are summaries of eight presentations selected by the editors; several others appeared in the first CCJ ONsite featuring content from the 501F and 501G meetings. more 

501F users discuss wide variety of engine topics

The user-only open discussion session conducted during the 2014 annual conference of the 501F Users Group, held at the Westin Mission Hills Resort & Spa in Rancho Mirage, Calif, February 16-20, was organized by engine section-beginning with the air inlet house and compressor. Discussion leaders all were members of the steering committee, chaired by Russ Snyder, plant manager, Cleco Power LLC. more 

What's eating up your LP evaporators: FAC or LDI?
Most O&M personnel at combined-cycle and cogeneration plants are aware that tube/pipe-wall thinning attributed to flow-accelerated corrosion (FAC) is a frequent cause of pressure-part failures in the low-pressure section of heat-recovery steam generators (HRSGs). Less common, but also of concern, is damage caused by liquid droplet impingement (LDI).  more

 In case you missed it.....

SPECIAL REPORT: Generator inspection first step in avoiding failures attributed to dry stator-winding ties

Indiscriminate cost-cutting and/or inattention to detail during equipment manufacture, installation, operation, and/or maintenance are conducive to forced outages and unbudgeted expenses. Generally speaking, unrealistic expectations are to blame, not individuals charged with doing their jobs faster and at lower cost.

   That's simply the way it is in today's competitive generation business. How many times have you seen contracts let on the basis of merit rather than cost? Asset and plant managers take the rap when availability and generating capability go south, so it's in their best interest to share information on emerging issues. User groups are critical to this timely communication. Why should multiple plants be forced out of service for the same reason? more
