Pipeline Design for Installation by Horizontal Directional Drilling

Sponsored by the Task Committee on Pipeline Design for Installation by Horizontal Directional Drilling of the Trenchless Installation of Pipelines Committee of the Pipeline Division of the Utility Engineering & Surveying Institute of ASCEPipeline Design for Installation by Horizontal Directional Drilling, Third Edition, addresses the design of major pipeline or duct segments to be installed by horizontal directional drilling (HDD) and discusses updates in drilling equipment, improvements for tracking, and considerations for using alternative pipe materials. HDD is a surface-launched trenchless excavation method for installing underground utilities and pipelines that is accomplished in three phases and uses a specialized horizontal drilling rig with ancillary tools and equipment.Topics includePredesign surveys,Drilled path design,Pipe design,Construction impacts, andAs-built documentation.MOP 108, Third Edition, is an updated and useful manual for design engineers, contractors, and owners interested in the HDD method and its abilities and limitations and applying the HDD method to relevant projects.
