The ultimate capacity of an existing outlet collector needed to be determined. HEA generated a finite element model of the outlet collector and a differential pressure load was applied. Our analysis considered material plasticity to find the ultimate collapse load. An...

Multiple cracking and leak failures have occurred in tubing located within an oil refinery economizer. Metallurgical examination of the failed tubes indicates that corrosion fatigue is the most likely failure mechanism. HEA performed a finite element analysis and...

A J-tube previously used as a firewater source, located in a leg of an oil platform, was found to be plugged. A systems upgrade to the fire protection system requires a functional fire water pump at the leg. Flooding of the leg was under consideration as a solution....

A rig in the Cook Inlet fleet was to be requalified for service by analysis for a 1000 year return period quake. HEA developed a finite element model to represent the platform, which accounted for the complex interaction between the drill pipe setback and the drilling...
