Midstream Oil & Gas Electrical Construction

Full electrical construction scope for compressor stations. Incoming power feeds, main power transformers, MV switchgear, motor control centers, VFD buildings and installations. Power distribution from the main bus through branch circuits. Compressor motor connections, often large HP motors at 2000HP and above on MV drives. Auxiliary systems including lube oil, cooling, fuel gas, and instrument air. Each of these systems has its own electrical and controls scope, and we handle all of it.

Gas processing plants are larger and more complex. Multiple process areas, each with its own electrical requirements. Cryogenic processing, amine treating, dehydration, NGL fractionation. We install the electrical and instrumentation for each process unit, coordinate with mechanical and piping trades, and maintain schedule across the full plant scope. We have done this work from greenfield through commissioning.

Midstream facilities have classified hazardous areas. Class I Division 1, Class I Division 2, and Zone 0, 1, and 2 classifications under NEC Articles 500, 501, 502, and 505. Our crews know the difference and what it means for every piece of equipment, conduit seal, and junction box they install. Explosionproof fittings, conduit seal-offs (EYS and EYD) within 18 inches of classified boundaries per NEC 501.15, proper conduit sealing, and intrinsically safe circuit installation. Getting this wrong is not just a code violation. It is a safety risk. We get it right.

We work with the area classification drawings per API RP 500 or API RP 505 and make sure every installation detail matches the classification for that location. Equipment ratings, wiring methods, sealing requirements, bonding and grounding. Our foremen verify classifications in the field, not just on paper. When the AHJ or the owner's inspector walks the job, our work holds up.

We install field instrumentation including pressure transmitters, RTDs, thermocouples, Coriolis and magnetic flow meters, and level transmitters (radar, guided wave, displacer). We run instrument tubing, pull and terminate instrument cable, and install control panels and PLCs. SCADA RTU installation, antenna and communication tower work, radio and cellular communication equipment, and fiber optic cable installation for plant networks. We terminate to the I/O list and the loop drawings provided by the controls engineer.

We do not program the PLCs or configure the SCADA system. We install the hardware, pull the cable, terminate every conductor, and verify continuity and proper function at the field device. The systems integrator handles programming. We make sure they have a clean, tested, and properly labeled cable plant to work with.

Normal and emergency lighting systems for facilities and access roads. Hazardous-area rated lighting fixtures in classified areas. LED upgrades for existing facilities. Grounding and bonding is critical on midstream facilities. We install ground grids, equipment grounding conductors, bonding jumpers, and static grounding for piping and vessels. We test ground resistance and verify compliance with the grounding study.

Heat tracing for process piping and instrumentation. Electric heat trace cable installation, connection, termination, and testing. Heat trace panels and temperature controllers. Cable tray systems including ladder, solid bottom, and channel for power, control, and instrument cable routing. Rigid conduit where conduit is specified. These are the supporting systems that make the facility work, and we install all of them.
