Live Flare Stack Drone Inspection at an Operational Gas Processing Facility in Humberside
Advanced Drone Inspection of Operational Flare Infrastructure Within a Live Process Environment
DJM Aerial Solutions recently completed a detailed drone inspection survey of a live operational flare stack at a gas processing facility within the Humberside industrial region, carrying out a comprehensive external visual assessment of the flare structure, flare tip assembly, structural support systems, and all associated access infrastructure while the flare remained operational.
The inspection focused on evaluating the condition of critical flare components including guide wires, turnbuckles, split pins, access ladders, structural steelwork, flare head assemblies, and associated fastening systems, all within a hazardous area environment where traditional inspection methods would have introduced significant operational complexity, safety exposure, and commercial disruption.
Using advanced industrial drone inspection technology, the survey was completed safely and efficiently without requiring scaffold installation, rope access personnel, shutdowns, or personnel exposure at height within the live process environment.
This project demonstrates the growing importance of industrial drone inspection within the oil and gas and gas processing sectors, particularly where operators require high resolution condition assessment of critical infrastructure while maintaining operational continuity.
Understanding the Importance of Flare Stack Inspection
Flare systems are among the most critical safety components within gas processing, petrochemical, refinery, and offshore infrastructure.
Their primary function is to safely dispose of excess hydrocarbons and process gases during:
Pressure relief events
Emergency shutdowns
Process upsets
Operational venting
Plant start up and shutdown activities
Flare systems must operate reliably under extremely demanding conditions involving:
High temperatures
Thermal cycling
Corrosive atmospheres
Wind loading
Continuous vibration
Combustion related degradation
Environmental exposure
Because flare stacks are critical safety systems, regular inspection and maintenance are essential to ensure structural integrity and operational reliability.
Failure or deterioration of flare infrastructure can lead to:
Structural instability
Loss of containment risk
Inefficient combustion
Excessive emissions
Component detachment
Unplanned shutdowns
Regulatory non compliance
Safety critical failures
As a result, flare inspection forms an important part of wider asset integrity and preventative maintenance programmes throughout the oil and gas sector.
The Challenges of Traditional Flare Stack Inspection
Traditionally, flare stack inspections are extremely complex and expensive operations.
Conventional inspection methods typically involve:
Extensive scaffold installation
Rope access teams
Working at extreme height
Temporary shutdowns
Specialist rescue arrangements
Hazardous area controls
Restricted operational windows
Permit controlled access
For live flare systems within operational gas processing facilities, these challenges become significantly more complex.
The flare stack inspected during this project remained fully operational throughout the inspection programme, meaning traditional inspection methodologies would have introduced major operational and safety implications.
Additional challenges included:
Live process operations
Potential hydrocarbon release risk
Thermal exposure from flare operation
Restricted access areas
Congested process infrastructure
Wind loading at height
Hazardous area requirements
Drone inspection technology provided a highly effective solution to these operational challenges.
Drone Inspection Approach
DJM Aerial Solutions deployed advanced external drone inspection technology to conduct a comprehensive close visual inspection of the flare stack and associated structural infrastructure.
Using stabilised enterprise drone platforms equipped with high resolution optical payloads, the inspection team safely captured detailed imagery and inspection footage across all critical components of the flare system.
The drone inspection scope included:
Flare head inspection
Pilot assembly assessment
Structural steelwork inspection
Guide wire inspection
Turnbuckle condition assessment
Access ladder inspection
Platform and handrail assessment
Fastening verification
Split pin verification
Corrosion assessment
Structural integrity review
The remotely operated inspection methodology allowed all inspection activities to be completed while maintaining safe stand off distances from the operational flare system.
Inspection of Guide Wires and Structural Support Systems
Guide wire systems form a critical structural component of many flare installations.
These systems are designed to stabilise the flare structure under dynamic environmental loading conditions including:
Wind loading
Thermal expansion
Vibration
Structural movement
Any deterioration within the guide wire system can compromise the structural stability of the flare assembly.
The inspection therefore focused heavily on assessing:
Guide wire condition
Connection points
Turnbuckle assemblies
Corrosion levels
Mechanical wear
Tensioning components
Fastening integrity
Split pin condition
Using high resolution zoom inspection capability, the drone platform allowed engineers to visually assess these components in detail without exposing personnel to working at height risks.
Inspection of Access and Egress Infrastructure
Safe access infrastructure is essential for ongoing maintenance and emergency intervention activities on flare systems.
The inspection included detailed visual assessment of:
Access ladders
Rest platforms
Walkways
Safety rails
Climb protection systems
Structural brackets
Connection points
The drone inspection methodology allowed difficult to access areas to be inspected rapidly while eliminating the need for personnel exposure at significant height.
Inspection of Flare Tip Components Within a Live Operational Environment
The flare tip assembly itself was one of the most critical inspection areas during the survey due to its direct exposure to continuous operational loading and extreme thermal conditions.
Flare tips within live gas processing facilities are subjected to prolonged exposure from:
High temperature combustion
Thermal cycling
Hydrocarbon exposure
Corrosive process gases
Atmospheric weathering
Vibration and dynamic loading
Over time, these operational conditions can contribute to mechanical degradation, distortion, corrosion, fastener deterioration, and combustion inefficiencies if not routinely monitored.
The drone inspection therefore focused heavily on obtaining high resolution imagery of all accessible flare tip components while the system remained operational.
Inspection areas included:
Pilot burner assemblies
Ignition systems
Flare nozzles
Flame retention components
Wind shrouds
Thermocouple locations where visible
Mounting brackets
Structural flare head supports
Fastening systems
Split pins and retaining assemblies
Corrosion protection coatings
Heat affected structural areas
Particular attention was given to the condition of mechanical fastening systems and split pin retention points due to the importance of maintaining component security within a live operational flare system.
Using high resolution optical zoom capability, the drone platform allowed the inspection team to safely capture detailed visual data of these critical components from controlled stand off distances while avoiding personnel exposure within the hazardous area.
The inspection also allowed engineers to assess evidence of:
Heat distortion
Surface oxidation
Mechanical fatigue
Component misalignment
Corrosion build up
Potential vibration related wear
Combustion related degradation
These findings provide valuable information to maintenance and asset integrity teams responsible for maintaining flare system reliability and process safety compliance.
Benefits of Drone Inspection Within Live Gas Processing Facilities
