Analysis of Theoretical Versus Actual HDD Pulling Loads

Abstract

In 1995, the Pipeline Research Committee at the American Gas Association published a manual titled Installation of Pipelines by Horizontal Directional Drilling, an Engineering Design Guide. This manual included a method to estimate loads and stresses imposed on pipelines during installation by horizontal directional drilling (HDD). Since the initial development of the calculation method, theoretical pulling loads determined by this method have been compared against actual pulling loads recorded during HDD installations. This paper presents an analysis of theoretical and actual pulling loads to determine if modifications to the calculation method are warranted based on documentation from completed HDD projects. The specific documentation utilized in this analysis consists of joint -by-joint carriage force gauge readings recorded during actual HDD installations.
