Elizabeth River Underground Line

< Back to projects

Client: UTEC Constructors Corporation
Location: Virginia, USA 

POWER teamed with UTEC Constructors for the design and construction of a double circuit HPFF cable system underneath the Elizabeth River for Dominion Virginia Power. Because the river is a major military and commercial shipping channel for the cities of Norfolk and Portsmouth, the line was required to be drilled under the river rather than laid in a trench. Horizontal directional drilling was used to make the approximately 7,500 foot river crossing, resulting in one of the longest HPFF pulls ever attempted and successfully completed. The cable extended an additional 600 feet from the river’s edge to the termination structure. POWER services included designing the cable installation, termination structure, and foundation, developing drawings to support the permitting effort and performing ampacity calculations.
