John, You (everyone?) may want to check out the most recent edition of "Wired" magazine (with the spooky looking black cover). They have an EXCELLENT article/interview with a Y2K "bughunter" for Texaco discussing their problems, vulnerabilities, and methodology for remediating their SCADA and embedded systems. (They even have some nice pictures of a handheld programming tool they use to access the code on each RTU-"remote terminal unit") Vital information I gleaned from the article? 1.) While each RTU is crucial for operational monitoring purposes, the expert opinion of the engineers is that there is nothing they know of that would interrupt or shut down the operation of their off-shore production systems. The problem is that, should their data collection SCADA systems fail, by law after 4 hours of failure they must shut their production operation down as a safety measure. 2.) Even in the event of failure of their systems over Jan, 2000, with the addition of necessary personnel (Note: with thousands of laid off oil workers looking for a job), they would be up and running again within a week or so. 3.) Main concern? Everyone else. Suppliers, vendors, their suppliers and vendors.... etc, etc. Special comment was made on the topic of utilities and how they are worried about the petroleum industry, while the petroleum industry is worried about the Utilities. 4.) Final note. It was noted that in order to prevent any repercussions from failure of power (something they can't control), Texaco will likely take its systems on the power grid and crank up their back up generators through the evening hours of Jan 1st. Interesting bit of wisdom from Texaco's Y2K project manager: Y2K can't be the end of time... It's too obvious. IMO, a must read for those interested in Embedded Systems and several examples of how they find and fix them. Also, interesting article on past power outages from NZ to the recent one in Canada/NE US last winter. What caused them and how people muddled through. Regards, Ron
