Pipeline Inspection

The Current Challenges with Pipeline Inspections

Pipelines are vital infrastructure for the transmission of oil and natural gas, connecting producing areas to refineries, chemical plants, home customers, and commercial demands. However, oil and natural gas are combustible and explosive substances that are typically delivered via high-temperature, high-pressure pipeline networks. Hereby, it is critical to monitor these pipelines to ensure that they are operating effectively.
However, traditional pipeline inspection methods have some issues, such as:

Use of crewed aircraft

Currently, the majority of energy companies use helicopters to monitor encroachment in potential pipeline Right-Of-Ways (ROW). Each expedition costs an average of $150,000, making more regular inspections than every six months almost impractical.

Foot Patrols

Once the aircraft confirms an encroachment, foot patrols, typically consisting of two personnel, are dispatched to these remote locations. Such manual site inspections take approximately 8 hours and cost approximately $500 merely to have a closer look and validate the threat.

Inability to send crew at all times

Pipelines can be hundreds of kilometers long and can be spread over vast remote locations. Sending operators to such locations can put human life at risk. Hereby, it becomes quite difficult to send inspection teams to cover such areas at all times. 

Time-consuming method

Traveling from one asset to another is frequently difficult. Operators may need to drive lengthy miles along gravel or dirt roads to visit several inspection sites. The distance and hard terrain may need a significant amount of time.

How can Drones with BVLOS Capabilities Help Oil and Gas Companies Secure Pipelines

Ease of travel between assets‍

Traveling between assets during inspection operations might become challenging because these pipes can span thousands of meters. The team may be required to travel long distances and to distant regions where there is no adequate road infrastructure.
Operators must travel to the sites, assess the asset, review their data, and then drive to another asset. Furthermore, they must repeat the entire process until all assets have been inspected. This can take a significant amount of time which can be costly for an industry like oil and gas.
However, drones can travel vast distances and reach difficult-to-access locations. Additionally, using drone-in-a-box systems, eliminate the need for continual re-launching, packing, and landing of drones which is majorly faced in manual-led VLOS operations.

Increase worker safety

Oftentimes, assets are located on high terrains or difficult-to-reach locations. Operators may need to set up substantial scaffolding or dangle from ropes to inspect this equipment. Any mistake here can result in severe consequences. Despite the industry’s strict regulations and safety standards, health and safety concerns persist. A BVLOS operation eliminates the operator’s danger by allowing them to undertake the flight mission from any remote location.

Simplify early detection of pipeline leaks‍

Drones are increasingly being used in the oil and gas industry for early detection of pipeline leaks. By using advanced drone technology including thermal cameras and visual or infrared cameras, these drones help the operators to identify gas leaks in storage tanks and pipelines with greater accuracy and efficiency than traditional methods.

These drones can easily access hard-to-reach areas and capture high-quality photos and videos of the pipelines and storage tanks. These data can be helpful to conduct image analytics for accurate and early detection of potential leaks or damage.
This allows operators to respond quickly and effectively to potential pipeline failure, minimizing the impact on the environment and reducing the risk of accidents. The use of drones also reduces the potential for human error, as operators can monitor the pipelines remotely, without the need for physical inspections.

Reduce heavy costs

Hiring a pilot and a helicopter, for example, can cost thousands of dollars. Regular inspections may become prohibitively expensive and time-consuming. Autonomous drone missions can minimize such costs while also minimizing human dependency.

Utilize readymade data and analytics via automated procedures

A human-led operation requires the operator to drive to the location and visually inspect the asset. Via autonomous operations, drone operators can run pre-planned drone flights and augment the inspection process. The drone will follow its routine, capture and store data which can be further assessed for detailed inspection as per need.

This enables the operator to quantify their assessment with turnkey data and analytics delivered via automated workflows. This simplifies the entire process and backs it up with data, which greatly aids decision-making. 

Ability to scale operations

While examining pipelines spanning thousands of kilometers, it becomes nearly impossible to conduct manual operations consistently. However, autonomous drones can be scaled up and deployed readily to fit the business’s needs as they can be programmed to conduct the desired tasks.
