Outage Planning: Don't Forget the Electrical Hazards!


Most of us go to work every day assuming that at the end of the day we will be returning home safely. Unfortunately, all too often this is not the case with many electrical workers. The facts are that over 7,600 electrical accidents occur annually in the United States and many of these incidents take place during an electrical maintenance outage. Many such accidents can be avoided with proper planning and plan execution.

Direct Drive vs. Gearbox: Progress on Both Fronts


For years, wind turbine manufacturers have been searching for ways to make direct drive turbines competitive with gearbox turbines. Direct drive technology has been praised for its design, which is less complex than gearbox technology, leading to easier operations and maintenance. This appeal has made direct drive especially coveted for use in offshore wind developments. However, the stigma of a bigger price tag and a heftier machine had disqualified direct drive from being a major competitor in the wind turbine sector – until recently, that is.

Steam Boiler Inspections Using Remote Field Testing


Forced outages of steam boilers due to tube leakages remain the leading cause of lost production in plants. Due to hundreds, if not thousands of linear feet of pipe, there is a high potential for failure without notice. One of the biggest challenges for maintenance and operations personnel is the prevention of tube failures in boilers and heat exchangers without causing significant loss to the company. When excursions from normal operating conditions occur, the question must be raised, “if our boiler tubes were damaged by the excursion (for example, overheating, or a condenser tube leak), how do we find out if we have a problem that could lead to failure?”

Corrosion Comes in Different Forms


Corrosion can have financial consequences. In the United States corrosion causes yearly losses of $47.9 billion in the utility industry, $29.7 billion in the transportation industry, $22.6 billion in the infrastructure sector, $20.1 billion on government structures and $17.6 billion in the production and manufacturing industry. This totals $275.7 billion yearly because of corrosion.

Clean Coal at Polk Power Station


Built with $140 million of support from the U.S. Department of Energy (DOE) as part of its Clean Coal Technology program, the Tampa Electric Co.-owned Polk Power Station is one of the United States’ first greenfield commercial integrated gasification combined-cycle (IGCC) power plants. Completed in 1996, the 260 MW Polk IGCC station sits on 4,300 acres of land that was once used for phosphate mines.

A Crash, Then Innovation


More than 20 years ago, the pilot of Israeli F-15 fighter crashed into his wingman in flight and had more than 90 percent of his right wing sheared off. The accident knocked out control surfaces and affected the plane’s symmetry. The plane should have flipped over and fallen out of the sky. But it didn’t.
