Installation of pipelines by horizontal directional drilling: An engineering design guide
This guide is to serve as a step by step guide for engineers engaged in the evaluation, design, and management of natural gas pipeline construction by Horizontal Directional Drilling (HDD). HDD pipeline design involves sophisticated engineering principles and should be performed under the supervision of a qualified professional engineer. The guide contains eight sections which address the following general topics. (1) A description of the HDD installation process; (2) Feasibility considerations including the state of the art in HDD, factors which limit its use, and a method for estimating the detailed cost of HDD installations under various conditions; (3) Components of a site characterization required for HDD design and bidding including geological factors, geotechnical aspects, and field survey requirements; (4) General considerations relative to drilled path design, pipe specification, external pipe coating, and multiple line installation; (5) Methods for analyzing pipe stresses both during installation and under operating conditions including a method for calculating pulling loads involved with pull back; (6) The impact of HDD operations on the environment including a discussion of drilling fluid functions, composition, quantities, and disposal methods; (7) General considerations relative to contract form, unknown subsurface condition risk, technical specifications, design drawings; and (8) Inspection requirements during construction including a detailed discussion of downhole survey calculation methods. Cost estimating, pipe stress, and drilling fluid quantity calculation methods are presented in a Lotus 1-2-3 spreadsheet format and demonstrated with sample problems. A diskette containing spreadsheet files is fixed to the inside back cover of the guide. Photographs and sketches have been included where appropriate to illustrate construction operations.
