ONEOK NGL Pipeline, L.P. Carney Booster Station Expansion

Project Scope

Oneok NGL Pipeline, L.P. expanded the thru capacity of their Carney NGL Booster Station by adding an additional 500HP, 480V, VFD controlled NGL pump and replacing the existing discharge valve.  A new 12’ x 26’ electrical building was added to house a new PLC control system, single phase 120VAC UPS, 480V/2000A/3P4W switchboard, 480V/250A/3P4W power distribution panel, 25kVA distribution transformer and 120-240V/225A/1P3W distribution panelboard.  The station utility transformer was upgraded to 1500kVA by Central Rural Electric Cooperative (CREC). 

Excellence updated the station P&ID’s, provided an overall site plan, mechanical plans, piping and relief valve isometrics, provided foundation plans and details for the new pump, electrical building, flood light pole and piping supports, reviewed Oneok purchased electrical building and electrical equipment drawings; provided an area classification plan and details; revised the existing one-line diagram; provided a facility grounding plan & details, an underground conduit routing plan and conduit & cable schedule.
