Overland Pass Pipeline Project
In 2006, two natural gas extraction plants in Wyoming needed to tie into a major interstate pipeline. REDD was contracted to design a system to inject the natural gas liquids (ngls) into the overland pass pipeline (OPPL) at each facility. One pipeline needed to convey 40,000 barrels per day (bpd), the other up to 100,000 bpd; both would travel several thousand feet across varied terrain and tie into the main natural gas pipeline.
Each plant required stages of booster pumps to raise the ngl’s pressure to over 1400 PSI, with controls for bypass and recirculation lines to prevent damage to the pumps in case of pressure spikes. The 100,000 bpd line also needed to accommodate variable flow based on input conditions.
The pipelines presented several project-specific challenges, including several jogs around existing buildings and equipment as well as a below-grade river crossing. REDD’s expertise with piping resulted in thoroughly engineered pipelines certain to operate reliably for many years to come.
