Refinery & Petrochemical Watch

Continuous satellite surveillance of refinery and petrochemical complexes to detect sabotage, unauthorised activity, structural anomalies, and emissions signatures before they become crises.

Refineries and petrochemical plants are among the most consequential pieces of infrastructure a nation owns. A single facility can represent five to fifteen percent of a country's liquid fuel output; a successful attack or undetected structural failure can cascade into fuel shortages, price spikes, and civil unrest within days. Ground-based security perimeters are porous, CCTV coverage is patchy, and human surveillance cannot watch dozens of tank farms, pipelines, and process units simultaneously around the clock.

A constellation combining shortwave-infrared and thermal imaging with synthetic aperture radar changes that equation entirely. SAR penetrates smoke, cloud, and deliberate obscurants — exactly the conditions that follow an explosion or fire — while thermal payloads flag anomalous heat signatures at storage tanks, flare stacks, and reactor vessels before visible damage appears. RF survey channels pick up unauthorised drone or communications activity inside exclusion zones. Daily to sub-daily revisits mean the baseline state of every tank, jetty, and pipeline segment is continually updated.

The operational outcome is a 24/7 watchlist that feeds the national critical infrastructure fusion centre: change-detection alerts when a tank farm shows subsidence or a pipeline corridor shows ground disturbance, thermal exceedance alarms tied to fire-and-gas thresholds, and post-incident damage mapping within two hours of a confirmed event. Operators move from reactive emergency response to predictive threat posture — and they do it without disclosing facility layouts or alert thresholds to a foreign commercial vendor.

What matters

A single major refinery outage can eliminate 10–20% of national refining capacity overnight; satellite monitoring cuts detection latency from hours to minutes.
SAR coherent-change detection identifies sub-centimetre ground deformation around tank foundations and buried pipelines — a failure mode invisible to conventional CCTV.
Thermal anomaly detection at 50–100 m resolution distinguishes a routine flare event from an uncontrolled heat buildup in a process vessel, enabling pre-emptive shutdown.
Foreign commercial imagery vendors are legally obligated to share tasking logs and customer data with their home government on national-security grounds — a structural intelligence leak for any sovereign operator.

Sovereignty score: 9/10 — Outsourcing refinery surveillance to a foreign satellite operator means a foreign government can see your facility status, your alert thresholds, and your response patterns — intelligence that has direct geopolitical and economic leverage value.

Foreign commercial SAR and optical vendors operate under their home government's export control and intelligence-sharing laws; tasking data for national refinery sites is legally accessible to foreign security services without the customer's knowledge.
Shutter-control provisions in US, Israeli, and European licensing regimes allow imagery to be withheld precisely when it is most needed — during a conflict, a covert attack, or a diplomatic crisis involving the site.
Refinery operational signatures (flare cadences, tank fill levels, throughput proxies) are high-value economic intelligence; a sovereign pipeline ensures this data never leaves a national classification boundary.
Escalation control requires that a government can surveil its own infrastructure continuously and covertly during a crisis without alerting an adversary that monitoring has intensified — impossible when tasking requests flow through a commercial operator.
