Zain Drone provides unmanned aerial vehicle (UAV) services for the oil & gas sector – including inspection services for onshore and offshore facilities. Our UAVs eliminate the need for human involvement in high-risk vertical structure operations and ensure a cost-effective alternative for conventional visual inspection methods requiring scaffolding, cranes, or rope access.
- Flare stack inspection
Quick and effective inspections of active flare stacks enable clients to maintain their production as UAV inspections do not require costly shutdowns of facilities. Further, drone-enabled inspection allows for the checking of assets from close proximity to gain a detailed view of the condition of the flare stacks, and the ability to focus on specific areas such as the atomizer pitting, pilot burner cracks, flare tip, radiation shields, pilot ignition systems, pipework etc. Additionally, radiometric thermal imaging inspections are also conducted simultaneously to identify temperature anomalies on the various flare components.
- Storage tank inspection
Zain Drone offers various solutions for storage tank inspections such as visual inspections of external and internal components of the tanks, thermal inspections of breather valves to detect possible leaks, ultrasonic thickness measurements (UTM) on internal and external parts of the tank and 3D laser scanning using LiDAR technology to evaluate tank deformation.
Customized ultra-high-resolution cameras can identify even the smallest issues on components such as cracks, corrosion, coating damage, damaged flanges, short bolting, wind grinder and deformation.
With the latest long-endurance UAVs, Zain Drone offers the ability to recreate high-resolution maps of entire storage tank farms that can be used to asses static or floating roof integrity, identify possible leaks on the floating roof tanks and pinpoint water pooling after heavy rainfall, all without the requirement to climb onto the tanks.
Specialized UTM UAVs are utilized for faster data collection without the need for rigging or scaffolding as is the case with traditional methods. A single UAV can capture up to 900 measurement points per day and does not require any support structures for operation.
Zain Drone uses high-precision magnetic crawlers in inspections where UAVs are inadequate for operation. Crawlers can carry multiple measurement instruments such as ultrasonic thickness probes, Eddy current, corrosion mapping instruments, and visual and thermal cameras. Crawlers are extremely useful in deployment in tight spaces where UAVs pose a risk to operations.
- Pressure Vessels, Columns, and Dehydrators
Zain Drone offers the latest UAV technology in confined space inspection. This specialized tool enables fast access to difficult-to-reach areas that previously required riggers and confined space entry permits. The UAV’s powerful radio technology and deployable extender antenna are capable of venturing deep into assets to provide a live view of areas previously unreachable by conventional methods. Dustproof floodlights and thermal imaging cameras allow operators to control the UAV in complete darkness, while the protection cage around the vessel ensures its propulsion system or any sensitive components inside the asset are not damaged.
- Robotics Inspection
Using robots for industrial inspections is about using guided systems that can safely reach and operate in places that are difficult and dangerous for people to access. Our inspection robots enable operators to plan outages more precisely and efficiently and thereby reduce downtime. This increases the availability of facilities and reduces the cost of maintenance, as well as ensures the safety of people from hazards.
Zain Drone’s robotics inspection capabilities include solutions such as ultrasonic thickness measurement (UT) modules, digital cameras, and corrosion mapping for confined space inspection, which can assist in the scrutiny of pressure vessels, pipes, chimney stacks, storage tanks, benzine columns, and dehydrators.
- Pipeline Surveying and Inspection
UAVs can cover larger areas than conventional monitoring methods and provide significantly more data with much higher quality and precision. High-resolution orthomosaics, Digital Surface Model (DSM) and Digital Terrain Model (DTM), which are georeferenced improve monitoring and inspection of oil & gas pipelines. Our GIS-enabled software allows users to identify issues along the pipeline and place geolocated marks on top of it with descriptions of the problem. These marks can then be exported into any other GIS-enabled software that can be used as guidance for maintenance teams.
- 3D Modeling and Reconstruction
UAV-recreated digital twins or 3D models are a great way to visualize the 3D dimensionalities of an object of interest.
These high-fidelity digital twins of assets are often used for plant change monitoring and in asset management and inspection.
- Confined Space Inspection
Confined spaces can present potential risks such as workers becoming stuck, exposure to toxic gases, liquids, chemicals, and other hazards. Keeping the inspection team outside the hazardous environment, we can complete remote inspection in confined spaces using specialized UAVs and robotics.
- Optical Gas Imaging (OGI)
Our UAVs permit clients to visualize and pinpoint gas leaks quickly and cost effectively. Monitoring pipeline, storage tank breather valves, chimney stacks, and other assets that are at risk of gas leaks are much easier to view using UAV and aerial optical gas imaging (OGI) cameras than conventional methods. With its high sensitivity characteristics, the OGI sensor detects different gases including benzene, ethanol, ethylbenzene, heptane, hexane, isoprene, methanol, methyl ethyl ketone, MIBK, octane, pentane, 1-pentane, toluene, m-xylene, ethane, butane, methane, propane, ethylene, propylene, and others. UAVs can quickly be deployed from a distance and dispatched to even the most dangerous areas without the risk to the personnel involved in the inspection.
- Thermal Inspection
Zain Drone UAVs are equipped with thermal imaging cameras that are sensitive enough to provide detailed insight on component condition. Thermal imaging cameras paired with UAVs can provide plant-wide coverage and offer better insights on asset conditions and potential risks.
