Engineered cable routing and support systems for upstream oil & gas production facilities, covering wellhead areas, gathering stations, processing skids, compressor units, utility modules, and hazardous-area power distribution networks.
Designed to support power, instrumentation, control, and communication cables under corrosive, vibration-intensive, and hazardous operating environments common in onshore and offshore upstream facilities.
Scenario Challenge
Hazardous Area Compliance in Hydrocarbon Zones
Cable support systems installed around wellheads, separators, and process skids must comply with hazardous-area installation requirements where flammable gases and vapors are continuously present. Improper material selection or grounding continuity can increase ignition risks during operation.
Severe Corrosion from H₂S, Salt Spray, and Chemical Exposure
Upstream facilities are frequently exposed to H₂S-containing atmospheres, saline environments, drilling chemicals, and produced water. Standard pre-galvanized systems often experience accelerated corrosion at cut edges and connection points.
High Vibration Around Rotating Equipment
Compressor packages, pump skids, and generator modules generate continuous mechanical vibration. Poorly supported cable routes can result in tray joint loosening, cable abrasion, and premature fatigue failure.
Complex Multi-Service Cable Segregation
Upstream sites require simultaneous routing of MV power cables, instrumentation loops, fiber optics, and emergency shutdown systems within limited rack space. Incorrect segregation may introduce electromagnetic interference and maintenance risks.
