For my day job I do predictive analysis on large gas compressors for the Oil and Gas industry. My clients want to assemble a compressor package and they want to reduce the likelihood that the unit will vibrate when they start it up. I use some state-of-the-art software to model their units, tap into my expertise regarding the physics surrounding vibration, predict the likelihood of vibration problems, and decide what changes are needed in order to make the unit run as smoothly as possible.
What’s the purpose of my job? Is it to discover the perfect way to build their unit so that they do not experience vibration problems? Actually, no! My job is not done until the unit is actually built the right way. Merely discovering the perfect way to build it is pointless unless that information ends up being implemented on the unit before they fire it up. Inherent to my job, then, is the human element. If I have personal knowledge of the perfect solution but it never leaves my mind, it’s pointless. It was all a waste. They’ll build the unit the wrong way, it will shake, and the end result would have been precisely the same as if I had never done any analysis in the first place. Continue reading →
