CEPA Surface Loading Calculation - Buried Pipeline (Demo)

This calculation tool was developed using equations and methods contained in the final report of “Development of a Pipeline Surface Loading Screening Process & Assessment of Surface Load Dispersing Methods” published by David J. Warman, etc. This report was developed by Kiefner & Associates, Inc for Canadian Energy Pipeline Association (CEPA) to provide a practical method which can determine the potential loading effects of the temporary crossing by vehicles and equipment in locations without established roads. It is also very useful to verify pipe stresses when cover depths or surface load exceeds limits embodied in API RP 1102.
