Managing Principal, Stress Engineering Services, Inc.


Greg Garic

Mr. Garic has over 35 years of experience in pressure systems engineering, particularly in the fitness-for-service assessment of fixed equipment in chemical plants and refineries. He is highly experienced in stress analysis, fracture mechanics, finite element analysis, creep and high temperature material behavior. His practice routinely involves evaluation and troubleshooting of a wide range of fixed equipment problems such as corrosion, crack-like flaws, hot spots, creep, deformation, and many other issues.

Fitness-for-Service Forum: Corrosion Assessment without the Grid
September/October 2018 Inspectioneering Journal
By Greg Garic at Stress Engineering Services, Inc.

In this column, I touch on what I see as an underused FFS technique for corrosion assessment: point assessment of corrosion – a technique that does NOT require a thickness grid. The reason I find this technique useful is largely because it’s so easy and cheap to implement.

High Temperature Life Assessment
May/June 2013 Inspectioneering Journal
By Greg Garic at Stress Engineering Services, Inc.

Predicting the remaining life of components operating in the creep regime is one of the trickiest problems encountered in the fitness-for-service (FFS) world.

Fitness-for-Service Assessment: Severe Local Corrosion
March/April 2013 Inspectioneering Journal
By Greg Garic at Stress Engineering Services, Inc.

If an operator finds cracking in a furnace waste heat boiler, excessive thinning in an absorption tower, or severe bulging in a converter, FFS assessments—not standard code analyses—are needed to evaluate the unit’s mechanical integrity. FFS assessments, according to the American Petroleum Institute (API), are “quantitative engineering evaluations that are performed to demonstrate the structural integrity of an in-service component containing a flaw or damage.”
