Custom
Electronics for the World's Most Demanding Energy
Environments.
Full-stack engineering partner for energy infrastructure hardware — intrinsically safe wellhead sensors, pipeline integrity RTUs, compressor condition monitoring, satellite telemetry for beyond-cellular locations, SCADA historian integration, and energy transition monitoring hardware. Designed with the full ATEX, IECEx, and functional safety constraint set from the first schematic.
The Energy Hardware Problem
Commercial-Grade Electronics Do Not Survive Energy Infrastructure
Oil and gas operations are increasingly data-hungry — but the hardware layer operates in conditions that destroy commercial-grade electronics within hours. Explosive atmospheres where a single spark from an improperly rated circuit can ignite a flammable gas cloud. Ambient temperatures from -40°C subsea arctic to 85°C in a Middle Eastern compressor station. Corrosive H2S atmospheres that degrade standard PCB finishes and connector contacts within months. Remote locations where the nearest technician is a four-hour helicopter flight away. And regulatory consequences for hardware failures that go far beyond operational disruption — production shutdowns, regulatory penalties, environmental incidents, and in the worst cases, loss of life.
Most electronics firms have never designed for Zone 1 explosive atmospheres. They do not understand that intrinsic safety is not a certification applied at the end of a design process — it is a design constraint that governs every component selection, power budget decision, and PCB layout choice from the first schematic. They do not understand that DNP3 and HART are not interchangeable with Modbus and that getting the protocol wrong means the field device will never communicate with the control room. They do not understand that a firmware update to a device that takes three months to access via helicopter is a project, not a deployment.
Three technology tailwinds are driving demand for custom energy electronics: the upstream digitization wave, where production optimization pressure is forcing operators to instrument producing wells that have been running for decades on manual gauging; the pipeline integrity monitoring mandate, where regulatory tightening following high-profile incidents is driving investment in distributed sensing that existing OEM hardware cannot cost-effectively deliver; and the energy transition, where the buildout of solar, wind, and storage creates massive demand for monitoring and control hardware that legacy utility instrumentation vendors are too expensive and too slow to supply. Energy technology vendors, oilfield services companies, and instrumentation manufacturers all need a hardware engineering partner with genuine hazardous area and industrial protocol expertise. Ankh serves all three.

Hazardous Area Hardware Engineering
Electronics Design →ATEX Zone 1 and Zone 2 hardware design using Ex ia and Ex ib intrinsic safety protection concepts. Entity parameter analysis — Voc, Isc, Ca, La — and IS barrier selection (Zener barriers and galvanic isolators) to maintain the intrinsically safe circuit integrity. T-class component selection for surface temperature compliance. IP66, IP67, and NEMA 4X enclosure design for outdoor and corrosive environments. IECEx technical file preparation and notified body engagement support.
Low-Power & Remote Firmware
Embedded Firmware →Ultra-low-power firmware architectures targeting 3-year and longer field life on solar and primary battery power for remote wellhead and pipeline monitoring applications. Sleep/wake scheduling coordinated with data acquisition and telemetry windows. Satellite firmware for Iridium Short Burst Data (SBD) and Inmarsat BGAN — minimizing expensive satellite airtime while maintaining data integrity. OTA firmware updates delivered over satellite with cryptographic verification.
Industrial Protocol Integration
IoT Architecture →Native firmware implementation of Modbus RTU and TCP, DNP3 Level 2 and Level 3, HART 7.x (master and slave), IEC 61850 GOOSE and MMS, Foundation Fieldbus H1, and OPC-UA on custom RTU and monitoring hardware. PROFIBUS PA awareness for DCS-connected field instruments. Protocol conversion and gateway firmware connecting legacy serial instruments to modern Ethernet-based SCADA architectures.
SCADA & Historian Connectivity
SCADA Integration →Real-time data delivery to OSIsoft PI (now AVEVA PI), Ignition by Inductive Automation, GE iFIX, Emerson DeltaV, Honeywell Experion, and ABB Ability platforms. DNP3 unsolicited reporting configuration, OPC-UA server implementation on RTU hardware, PI Asset Framework integration. SCADA integration middleware that connects custom hardware to existing control room infrastructure without disrupting operational continuity.
AI & Predictive Analytics
AI & Analytics →Predictive maintenance AI for compressor failure prediction, pump wear detection, heat exchanger fouling from pressure-drop trends, and transformer degradation from DGA (dissolved gas analysis) data. Edge AI for on-device anomaly detection — identifying abnormal pressure, flow, or vibration signatures at the RTU before transmitting alerts to the control room, reducing satellite airtime costs while accelerating incident response. Production optimization AI for decline curve analysis and artificial lift optimization.
Functional Safety & Certification Support
Certification Support →IEC 61511 SIL-aware firmware design — safe failure fraction analysis, hardware fault tolerance considerations, and systematic capability documentation for firmware in safety instrumented system applications. Ankh does not claim SIL certification, which requires formal third-party assessment, but designs with SIL process awareness from day one. IEC 62443 cybersecurity awareness for OT/IT boundary devices. NERC CIP awareness for grid-connected assets. FCC and CE certification support for wireless field devices.

Why Engineering Teams Choose Ankh
Hazardous Area by Design
Intrinsic safety is not a certification applied at the end of a design process — it is a design constraint that governs every component selection, power budget decision, and PCB layout choice from the first schematic. Designing for ATEX Zone 1 means working within IS entity parameters, selecting components with appropriate temperature class ratings, maintaining required creepage and clearance distances for the application voltage and pollution degree, and documenting the intrinsically safe circuit in a form that satisfies a notified body. Ankh designs for ATEX and IECEx from day one — not as a retrofit.
Protocol Fluent at the Firmware Level
Modbus, DNP3, HART, IEC 61850, Foundation Fieldbus, OPC-UA — implemented natively on custom silicon, not through off-the-shelf communication modules that add cost, latency, single-vendor dependency, and an additional failure mode to your hardware architecture. DNP3 Level 2 and Level 3 data object implementation. HART multi-drop master and slave. IEC 61850 GOOSE messaging with sub-4ms latency for protection applications. Your control room sees a well-behaved, standards-compliant device from the moment it is powered on.
Remote Deployment Ready
Satellite telemetry, multi-year battery life, solar power management with battery health monitoring, and OTA firmware updates delivered over Iridium SBD — hardware designed for assets that a field technician visits once a year, not once a week. Ultra-low-power firmware architectures with aggressive sleep scheduling, adaptive telemetry intervals based on event significance, and data buffering for connectivity gaps. When the satellite window opens, the data is there and the firmware is current.
Full Stack from Sensor to SCADA
Sensor hardware, intrinsically safe barriers, RTU firmware, SCADA protocol integration, cloud data pipeline, and field technician app — under one roof, with no integration gaps between disciplines. The sensor team and the SCADA integration team are the same team. The firmware engineer who writes the DNP3 stack is the same person who validates the historian tags against the control room configuration. Hardware failures in oil and gas have consequences that extend well beyond operational disruption. We design accordingly.
Solar-Powered Satellite RTU for Unconventional Production Field
ATEX Zone 2 certified solar-powered wellhead RTU for pressure, temperature, and flow monitoring across a 280-well unconventional production field. 3-year field life without maintenance visits, Iridium SBD satellite telemetry, and DNP3 Level 3 integration with the operator's OSIsoft PI historian for real-time production reporting and regulatory compliance data logging.
