LOCATION: Mont Belvieu, TX to Nederland, TX
PROJECT: Lone Star & Orbit 68-Mile Dual 20-Inch Pipeline
SCOPE: MPH provided project planning, development, engineering, design, mapping, surveying, property plat and permit acquisition document preparation for the 68-mile Energy Transfer Dual 20-Inch Lone Star and Orbit Pipeline Systems Project. Approximately 500 ROW Plat and Permit Documents, 90 Alignment, & 200 Pipeline Crossing Design Construction Drawings were developed. The 5 ft. on centers dual 20-Inch pipelines were designed and installed as Simultaneous Conventional Co-lay and Stacked & Staggered Horizontal Directional Drill (HDD) installations. Typical pipeline conventional trench excavations were a minimum of 6-8 ft. deep and 10-12 ft. wide. HDD stacked and staggered installations ranged from 1,200 LF to 7,000 LF. A total of approximately 136-miles (720,000 LF) of 20-Inch steel pipe was installed. To meet the pipeline construction schedule demand, MPH survey personnel and equipment were mobilized and deployed from the MPH Midland, San Antonio, Houston, Winnie, and Houma Operations. Multiple Tactical 2-Man Land & Amphibious Field Survey Crews were simultaneously deployed throughout the 68-mile project theatre.
