An advanced software solution for HDD design and installation of pipelines and utilities.
The New Horizontal Directional Drilling PowerTool (HDDPT) enables safe and efficient drilling, reaming, and installation of pipelines at road crossings, water bodies, and railroad right of ways.
Using HDDPT will lower construction risks and costs by providing:
� Advanced HDD design insight and planning for successful execution of all operations.
� A solution that minimizes excavation complexity and lowers cost of pipeline installation.
� Advanced borehole stability to prevent borehole collapse or washout.
� Ad Hoc operational calculations to monitor drilling/ pulling operations.
Address all HDD Applications with the latest HDDPT Technology
HDDPT is specifically developed for professionals involved in the design, engineering, and installation of pipelines and utilities by horizontal directional drilling. HDDPT can be used for the design and installation of pipelines and conduits for the following applications:
�Natural Gas
� Petroleum
�Water & Sewer Lines
�Other Fluids
� Telecommunications
� Electric Power Lines
HDDPT has all the engineering calculations needed to quickly solve HDD project challenges. The underlying mathematical models and technical procedures are based on the latest HDD technology and are following current regulations, standards and recommended practices. HDDPT addresses standard stress and pull force analysis for steel and polyethylene pipe, drilling fluid hydraulic and pressure analysis, and addresses the installation of cables in conduits.
