Featured Capability - Urban Infrastructure

Horizontal directional drilling (HDD) is a proven method of installing pipelines, including these pipelines being pulled under a ship channel. Planning and designing pipelines like these in developed urban or port areas includes planning for stringing and pulling the pipeline, subsurface investigation, rights-of- way, permits, work space, and contractor coordination. We apply this expertise in subsurface utility engineering and coordination to many types of urban infrastructure development projects.

Featured Capability - Fuel Supply Systems

Pipelines transport gasoline, diesel, and jet fuel from the refineries and marine terminals to distribution terminals in urban centers, airports, and military bases. SPEC provides planning, engineering, and overall project services for all parts of these fuel supply networks, including the system for receiving jet fuel from a pipeline pictured here.

Featured Capability - Upgraded Process Systems

System upgrades adapt to changing process conditions and rates and improve operations, efficiency, and reliability. SPEC provides process engineering and system planning for oil and gas production (as pictured here), gas processing, and oil refining, and for the support systems associated with these facilities.
