Autonomous Drone Inspection: Tested at a Live Energy Facility
Overview In late 2025, Terra Drone Arabia ran a field test of an autonomous drone inspection setup at a live oil and gas facility. The aim was simple: show that
Comprehensive aerial, ground, and underwater drone inspection services across Saudi Arabia and the GCC region, delivering high-resolution visual, thermal, and NDT data without scaffolding, shutdowns, or confined-space entry for inshore and offshore facilities. Trusted by oil & gas, refinery, utilities, mining, and marine operators.
BENEFITS & SLA
Non-contact, multi-modal drone and ROV inspections backed by GACA-certified pilots, ISO-aligned procedures, and SLA-driven reporting, purpose-built for Saudi Arabia’s most demanding industrial assets.
Sub-millimeter visual and radiometric thermal imagery to detect corrosion, micro-cracks, hotspots, and coating defects invisible to manual inspection.
Reach flare tips, chimneys, stacks, tanks, pressure vessels, dam walls, and subsea pipelines, without rope access, scaffolding, or confined-space entry.
Initial inspection summary within 48–72 hours; full report with annotated defect logs and 3D mapping within 3–5 business days.
Live (online) inspection on running assets without operational shutdown, or planned offline inspection during turnaround for deep-dive defect analysis.
Eliminate scaffolding, rope access teams, shutdown coordination, and extended manpower, cutting total inspection cost by up to 70%.
Capable on doing inspection for inshore and offshore facilities to maintain asset integrity for long term function-ability.
CHALLENGES
Manual inspection methods expose teams to risk, slow operations, and miss critical defects across vertical, confined, and underwater assets.
Manual inspections miss micro-defects and rarely produce repeatable, uniform measurements across a full asset surface.
Many traditional inspections require partial or full shutdowns of operations, halting production and eroding revenue.
Tanks, chimneys, flare tips, stacks, pressure vessels, and offshore platforms are dangerous or impossible to reach manually.
Working at height, in confined spaces, or hazardous zones exposes inspection teams to falls, asphyxiation, and chemical contact.
Active hydrocarbon, toxic gas, high-temperature, and explosive zones make manned inspection slow, expensive, and unsafe.
Scaffolding, rope access, shutdown coordination, and lengthy manual reporting inflate budgets and delay maintenance decisions.
TECHNIQUES & METHODS
Non-contact, multi-modal drone and ROV inspections backed by GACA-certified pilots, ISO-aligned procedures, and SLA-driven reporting, purpose-built for Saudi Arabia’s most demanding industrial assets.
A fixed docking station launches, charges, and retrieves the drone on a schedule, giving refineries and tank farms repeat perimeter surveillance and thermal screening from a safe distance. It supports drone inspection services by flagging anomalies around stacks, pipe corridors, and oil storage tanks for closer follow-up, not replacing detailed internal or NDT work.
A tethered ROV covers the work below the waterline: subsea pipeline corridors, hull plating, dock piles, and submerged transitions that aerial surveys cannot reach. Underwater ROV inspection adds close visual evidence below water and can be reported alongside topside drone findings when both are in scope.
High-definition CCTV crawler inspection for DN190–DN2000 underground pipelines up to 120 m working distance. Features condition-matched dry and wet mainline deployments, Terra SewerX AI defect localization, WRC-referenced condition grading, and certified inspector review without manned trench entry.
Long-range zoom optics and a radiometric thermal sensor help inspectors review external stack condition, chimney surfaces, and insulation hotspots while the asset stays online. Flare stack drone inspection can reduce scaffolding, shutdown time, and at-height exposure when close-contact testing is not required.
A collision-tolerant caged drone flies inside storage tanks, columns, and pressure vessels to capture weld seams, shell condition, and coating issues before people are sent inside. Confined space drone inspection reduces manned entry and helps plan any follow-up work that still requires hands-on access.
A radiometric thermal camera traces heat patterns across insulated pipework and process equipment, highlighting areas where moisture, insulation failure, or corrosion under insulation (CUI) may need closer verification. Oil & gas thermal drone inspection is best used as a screening layer that prioritizes follow-up NDT and maintenance checks.
A contact-capable drone presses an ultrasonic, EMAT, or DFT probe directly to vertical steel and returns thickness or coating values at defined test points. This NDT drone inspection workflow feeds RBI programs and wall-loss trending while reducing rope access on suitable tank shells, stacks, and process columns.
A four-legged industrial robot walks gravel, stairs, and wet metal grating to run repeatable visual and thermal patrols when equipped with the right sensors. The quadruped robot for inspection fits mining plants, conveyor galleries, and dense process facilities where ground access matters more than altitude.
DELIVERABLES
Structured, audit-ready inspection outputs aligned with international standards and your asset integrity workflows.
