PITTING CORROSION IN CONVENTIONAL FOSSIL BOILERS AND COMBINED CYCLE/HRSGS By: Wendy Weiss Pitting is a localized corrosion phenomenon in which a relatively small loss of metal can result in the catastrophic failure of a tube. Pitting can also be the precursor to other damage mechanisms, including corrosion fatigue and stress corrosion cracking. Pits often are […]
STREAMLINING REQUALIFICATION OF HEAVY LIFT EQUIPMENT By: Mike Battaglia and Jason Van Velsor BACKGROUND Proper control of heavy loads is critical in any industrial application as faulty equipment or practices can have severe consequences. The lifting technique, equipment, and operator qualifications must all meet or exceed applicable standards to ensure industrial safety. The significance of […]
Recovery Best Practices By: Dan Tragresser When a unit trips or experiences an event, the site will incur costs associated with the loss in production and regulatory penalties. Based on the severity, the outage scope may include hardware replacement and, if applicable, the purchase of make-up power. These costs can quickly drive the decision to […]
Risk and Cost Reduction in Real Time Jason Van Velsor, Matt Freeman, Ben Ruchte Installed sensors and continuous online monitoring are revolutionizing how power plants manage assets and risk by facilitating the transformation to condition-based maintenance routines. With access to near real-time data, condition assessments, and operating trends, operators have the opportunity to safely and […]
High Energy Piping Monitoring SI moves beyond the pilot application of a High Energy Piping monitoring program designed to reduce operational risk and optimize maintenance activities. SI has successfully implemented the initial application of an integrated monitoring solution that provides insight into damage evolution and operational risk using real-time data and automated engineering intelligence. This […]
The Corporate Magazine (www.thecorporatemagazine.com) approached us recently to be featured in their “Top 20 Most Dynamic Leaders” issue. We saw this as a unique opportunity to elevate our brand by briefly discussing our two-year journey under Mark, expanding on our history, highlighting our offerings, and sharing our unique value to the industries we serve. To […]
A CASE STUDY FROM THE FERMILAB LONG BASELINE FACILITY By: Keith Kubischta and Andy Coughlin, PE, SE All around us is aging concrete infrastructure. From the dams holding back water, to the nuclear power plants creating carbon free electricity, to the foundations of our homes and offices. Though many advances have been made in the […]
TECHNOLOGY INNOVATION – THICK FILM SENSORS By: Jason Van Velsor and Robert Chambers The ability to continuously monitor component thickness at high temperatures has many benefits in the power generation industry, as well as many other industries. Most significantly, it enables condition-based inspection and maintenance, as opposed to schedule-based, which assists plant management optimizing operations […]
ENGINEERING CRITICAL ASSESSMENT By: Pete Riccardella, Scott Riccardella and Chris Tipple The Structural Integrity Associates, Inc. Oil and Gas Pipeline group recently supported an Engineering Critical Assessment to assist a pipeline operator manage the Selective Seam Weld Corrosion (SSWC) threat to an operating pipeline. SSWC occurs when the fusion zone of a certain type of […]
