OIL & GAS

A Communication Failure
in an ATEX Zone
Doesn't Mean Downtime.
It Means Fatalities.

Offshore platforms, onshore refineries, and pipeline corridors demand communications infrastructure that operates flawlessly in explosive atmospheres, remote locations, and extreme conditions — where commercial networks don't reach and WiFi propagation fails.

⚠️ IEC 60079: Every wireless device in a hazardous zone requires ATEX certification. Standard enterprise WiFi = illegal and lethal.

THE OPERATIONAL REALITY

Four Connectivity Crises Costing You Millions Per Incident

🔥 ATEX Zone Communication Void

Standard industrial WiFi cannot be deployed in IEC 60079 Zone 1/2 hazardous areas. Operators in compressor stations, flare zones, and wellhead areas rely on wired comms or exit the zone to radio in — creating dangerous, costly communication delays during critical operations.

↳ HCT: ATEX Zone 1/2 certified 5G devices. Intrinsically safe handsets with guaranteed connectivity throughout the hazardous perimeter.

🌊 Offshore Platform Isolation

Offshore rigs in the Arabian Gulf sit 50–200km from shore — beyond all terrestrial coverage. Legacy VSAT delivers 1–5 Mbps shared across 200 workers. Real-time SCADA, remote expert video support, and HSE video surveillance are impossible on bandwidth-starved satellite links.

↳ HCT: Platform-mounted private LTE with microwave backhaul to shore + VSAT failover. 100+ Mbps dedicated per platform.

🔌 SCADA on Public Networks

ICS/SCADA systems managing valves, pumps, and compressors along pipeline corridors are increasingly routed through commercial carrier networks — creating cybersecurity attack surfaces. A latency spike of 100ms on a valve control signal can trigger a cascade failure across the pipeline system.

↳ HCT: Dedicated private LTE for SCADA with <5ms deterministic latency. Air-gapped from public internet. IEC 62443 compliant.

🚁 Remote Site Crew Connectivity

Pipeline inspection crews, wellsite geologists, and maintenance technicians in remote desert or mountain terrain operate with zero coverage. Real-time LiDAR inspection data, drone feeds, and location tracking cannot be transmitted — creating HSE compliance gaps and delayed decision-making.

↳ HCT: Band 28 700MHz for 20–40km cell radii in open terrain. Rapid-deploy masts for remote sites. Drone/UAV data offload.

Frequently Asked Questions

Why do oil and gas operations need private 5G rather than Wi-Fi or public cellular?

Upstream and downstream sites cover large, remote and hazardous areas where public coverage is unreliable and Wi-Fi cannot span the footprint. Private 5G gives predictable coverage, guaranteed capacity for safety-critical traffic, and on-site control. HCT Group supports operations across areas of up to 11,000 square kilometres.

Is the equipment certified for hazardous ATEX zones?

Yes. HCT Group deploys ATEX-certified radio and device equipment rated for hazardous classified zones in oil and gas environments.

Can private 5G coexist with existing TETRA radio?

Yes. HCT Group deploys and integrates both, and supports phased migration so that TETRA voice continues to operate while broadband data, video and IoT move onto private 5G.

What applications run over the network?

Mission critical voice, lone worker and man-down safety, fixed and body-worn video, drone and robotic inspection, SCADA and telemetry backhaul, asset tracking and predictive maintenance sensing.
