All these “old dogs” were available to run during preparations for the end of the millennium and

the Y2K expectations of computer glitches taking down the power grids. This event never

occurred, but the gas turbines were ready to perform, if needed. They are approaching 50 years

of operation in 2011. The Southampton turbine is essentially “as built,” with virtually all its

original controls and auxiliary systems. It still has the original controls and auxiliaries, including

the fuel regulator. See Chapter 7 herein.

The MS5001D units in the early 1960s were rated at 11,250 KW at NEMA conditions

(compressor inlet of 80 ºF at an elevation of 1000 feet, which relates to an ambient pressure of

14.17 psia).

As the decade of the sixties continued, only a few GE units were sold prior to the 1965 Blackout

(an average of just 4 units per year). The MS5001 evolved to the model “K” by the time the

lights went out in 1965, and were then rated at 14,000 KW when fired at 1500 ˚F. The so-called

“L” and “LA” Frame 5 turbines came in the late 1960s. They were rated approximately 15,000

KW and fired at 1650 ºF. Many were dual fuel and they were often configured in two or four-

unit power blocks (PB). In these cases, the starting means of at least one of the turbines was by

diesel engine. If the control cabs were not “stand alone” and on the end of the accessory bases,

the plants often “shared” many auxiliaries like batteries, CO-2 fire protection systems and fuel

forwarding skids. For instance, at Buzzard Point in Washington, DC, there are four 4-unit

blocks. They are configured in two rows of eight units and the two control cabs are in the center

of the site and connected at both ends, allowing the operator to remain inside one structure to

start all 16 units.

I am still enjoying the career of field engineering after over four decades. Here I am below in

Fig. E-2 checking out a Mark IV panel at PGE in Pittsfield, MA in 2001. Troubleshooting,

training and consulting has kept me active in the career of field engineering. We field engineers

are known as Turbine Cowboys in the industry.

I am pleased to say that a college degree from Umass-Amherst got me the job at General

Electric. The twenty years that followed included FEP training, field assignments on gas

turbines, factory test on steam turbines and teaching at GE‟s training center. The two companies

I started kept me active in the power industry.

Finally, as I am inclined to say: Knowledge + Experience = SAVVY.

This was the magic formula for a successful career in gas turbine field engineering services. For

all this and more, I am very grateful to General Electric for hiring me and later allowing me to

transfer from the Technical Marketing Program to Field Engineering Services. Later in my

career, I am thankful for an assignment in factory test in steam turbines and being hired to be an

instructor at the FEDC. The latter job lead to promotion to the job of manager of the Field

Engineering Program. My return to the field as manager of the TEPCO project in Japan for a

couple of years was a great assignment. Finally, I have to thank GE for giving me the gumption

to go out and start my own companies.

I have often thought of the poem by Robert Frost that addresses how forks in the road are

sometimes present with a choice about taking one path or the other along the trail of life. He

talks about taking the one “I took the one less traveled by, and that has made all the
