Barr provided design engineering services for upgrades along a pipeline in the midwestern U.S. We designed four new pump stations and expanded one custody-transfer-metering facility. All sites required noise analyses, air modeling, and wetland investigations to develop designs that worked within tight confines while minimizing environmental and public impacts.
Designs included piping and foundations for planned future installation of additional mainline pump units. Our work entailed mechanical, electrical, structural, civil, and geotechnical design, as well as stress analysis of the mechanical systems and vibration analysis of the pumps and pump foundations. In addition, we provided project management and technical assistance and worked with the construction team to provide accurate as-built documentation for other sites.
Phase II involved expanding storage capabilities and upgrading facility flexibility with the addition of five 390,000-barrel storage tanks, four booster-pump manifolds, two transfer pumps, one large distribution manifold, facility containment, a fire pond and fire-suppression system, and additions to existing facilities to support these upgrades. Our services again included mechanical, electrical, structural, civil, and geotechnical engineering. Barr also provided on-site engineering assistance, construction oversight, and environmental inspection.
The mechanical portion of the design included a full 3D design, detailed steady-state and transient hydraulic analysis, pump sizing, complete stress analysis, procurement, material approval, and construction assistance. The electrical design included several new electrical service buildings, distribution systems, and cable trays. Working closely with the team’s geotechnical engineers, we designed platforms, pipe supports, valve supports, and building foundations. We also verified tank locations, designed tank and spill containment infrastructure and roadways, and coordinated the work of an interdisciplinary team.
