Horizontal directional drilling (HDD) projects are increasing in popularity and frequency within the pipeline industry. With continuing pressure to reduce interruptions to the surrounding environment and increase the economical viability of the HDD process, new technologies are being developed to meet the mounting demands. By utilizing a specialized and patented technology found in a composite wrapping system, and optimizing the formulation and installation techniques specifically for fast curing times and high abrasion and impact resistance, there has been a dramatic cost and time savings value added to HDD projects. Protection of field joint coatings is a critical part of the success of these projects to insure no failures occur thereby preventing the costly need to re-pull the pipe. This paper will present the background, technical, and economical aspects of this system and its beneficial uses for HDD projects as well as some case studies from successful projects.
