HDD Design
Detailed HDD Design
Designing an HDD project requires an experienced assessment of many key factors:
- Entry / exit angles, arc radius, and required depth of cover
- Integration of geotechnical information, drilling and pipe design
- Pull force, bending and tensile stresses applied to the product pipe
- Conservative design parameters to accommodate potential anomalies
- Safe Drilling and hole opening operational practices
- Suitability of layout area, pipeline tie-ins, and other construction site conditions
- Suitability of pulling and lifting plans for final pipe installation
