MarkWest Energy Partners LP Gas Processing Facility – Project by CEC Inc.
MarkWest Energy Partners LP’s objective is to efficiently and reliably deliver natural gas midstream services. CEC plays a crucial role in helping MarkWest achieve this objective by providing expert guidance in site selection and pipeline routing. CEC’s approach involves thorough research to identify optimal sites and rights-of-way (ROW), considering factors such as stream and wetland impacts, geological hazards like landslide-prone soils and rock outcrops, and utility locations. This detailed analysis allows for informed decision-making in site and ROW selections, minimizing potential risks and streamlining project execution.
CEC’s expertise extends to preparing preliminary layout and grading plans, estimating earthwork volumes, and conducting constructability reviews. This proactive approach in the early stages of project development is invaluable to MarkWest Energy Partners LP, ensuring projects are well-planned and efficiently executed. To date, the collaboration between CEC and MarkWest has resulted in engineering and permitting designs for ten gas processing and fractionation facilities and over 600 miles of natural gas liquids (NGL) and natural gas pipelines.
