Energy professionals and the general population are both acutely aware of the explosion of a Pacific Gas & Electric Co. (PG&E) natural gas pipeline in San Bruno, Calif., that led to the death of eight people and the total destruction of 38 homes in September 2010. The tragic accident garnered immediate national attention, thrusting the natural gas industry into the spotlight. The California Public Utilities Commission’s (CPUC) Independent Review Panel neatly encapsulated the sentiment surrounding the event: “The fact that a large segment of pipe literally blew out of the ground in an urban neighborhood and the residents were generally unaware of the proximity of a high-pressure natural gas transmission system to their homes—raises significant public safety concerns.”

A large swath of Southern California, parts of Arizona, and Northern Baja Mexico was blacked out on Sept. 8—leaving seven million people in the dark—after an Arizona utility worker fixing faulty equipment near Yuma reportedly tripped the 500-kV North Gila–Imperial Valley transmission line, causing the outage. The blackout prompted two units at the San Onofre Nuclear Generating Station to go offline, stranded many people in elevators and trains, shut down airports, cut air conditioning on a day well above 90F, and caused damages of $97 million to $118 million, according to early estimates from the National University System’s Institute for Policy Research.

In the May issue, we discussed the importance of either preventing copper plating of the high-pressure (HP) steam turbine rotor or finding a good foam or mechanical removal means of restoring lost efficiency. In that article we noted that “copper deposits typically form on the stationary nozzle block or first-stage stationary blades” and that those deposits usually result in a steam turbine loss of capacity at a rate of about 2 to 3 MW per month. We also stated that the “general rule of thumb is that there is a reduction of about 1 MW of generating capacity for each 1 to 2 pounds of deposit that accumulates on the HP turbine.

An intellectual property battle between Massachusetts-based American Superconductor Corp. (AMSC) and China’s giant wind turbine maker Sinovel in late September culminated with an Austrian court conviction of a former AMSC employee, who was arrested in Austria and who pled guilty to corporate espionage charges. The court charged Dejan Karabasevic, a 38-year-old Serbian engineer, with stealing AMSC’s software, modifying it, and secretly selling it to Sinovel.

The power generation industry is a highly competitive one in which players continue to change and the race for profits is a tough one with the challenge of heavy environmental regulations. One of the most overlooked areas for cost savings is safety. Notwithstanding the moral and legal responsibilities that power plant management has for creating a workplace where everyone can work without injury, reducing and eliminating workplace injuries and illnesses is good for business.

This is the fourth in a series of predictive maintenance (PdM) articles that began in the April “Focus on O&M” with an introduction to PdM as a process whereby maintenance is performed based on the condition of the equipment rather than on a predetermined interval. In the May and July issues, we began exploring specific PdM techniques, such as motor-current signature analysis and oil analysis.
