A major international energy company owns and operates a refined petroleum products pipeline in the San Francisco Bay Area called the Bay Area Pipeline (BAPL). This pipeline originates at this major international energy company where the Richmond Pump Station is located. This pump station contains two 1,500 hp electrically driven pumps. Performing preventative maintenance on the incoming electrical service equipment became problematic and prompted CPL to replace the service load break switch and 3,750 kva, 12kv / 2.4kv transformer. To maintain station operations, this new load break switch and transformer are to be fed by a parallel service (pole-mounted air break switch and metering) that will allow the majority of the electrical upgrade work to be performed while the station continues to operate with minimal downtime. In addition to the electrical work, load break switch/transformer monitoring and control circuits were required to provide remote monitoring of the service via an existing PLC at the station. New electrical duct banks were designed for electrical and control wiring between the existing motor control center building and the new transformer.
The supplier provided 3D model of the 3,750 kva transformer.
EDM Services provided $75,000 of engineering and design services for the electrical and civil designs required for the project. This engineering included: electrical one-line development, revision of electrical area classification drawings, conductor and raceway sizing, short-circuit calculations, equipment grounding plan, overhead powerline design, duct bank design, reinforced concrete design of the slab on grade foundation and integrated conduit trenches, and other supporting electrical and civil details.
