Scientists have been putting them in virtual reality simulators to help improve unmanned aerial vehicle (UAV) or drone technology. Although the bee currently has the edge, drone technology is catching up. So, what are the challenges and opportunities when using drones to monitor and inspect oil and gas pipelines?</span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 12px;">Drones are being employed in a wider range of sectors and for myriad purposes. The further growth and adoption of this technology will be encouraged by consumer market growth, spillovers from the military sector and the possibilities opened up by 5G. The potential for drones to revolutionise the world of maintenance is clear. They certainly pass the ‘D test’: tasks that are dirty, dangerous and dull could all be left to drones.</span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 12px;">BP, Shell and Exxon have already begun using drones for asset inspection and other tasks. Following an incident in 2008, where Exxon’s use of sonar technology was implicated in the deaths of 100 whales near Madagascar, the company recently used drones to help monitor the locations of whales off the coast of Santa Barbara. But what about the benefits for pipelines?</span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 12px;">Opportunity in the pipelines</span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 12px;">From Alaska to the Niger Delta, oil pipelines are often located in inhospitable or even dangerous environments. In addition to their vast size, this fact makes maintenance through visual inspection a dangerous task. By handing the task of visual inspection over to drones, human workers are no longer in harm’s way.</span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 12px;">Making the task of maintenance safer is not the only incentive. Early investors in the technology are seeing significant cost savings. Although it is difficult to quantify the precise saving, research by Roland Berger has estimated that drone-based inspection of oil and gas rigs leads to cost savings of around 90%. The same research estimated that the use of drones has cut maintenance times from eight weeks to five days. The bottom line is that drones will provide a more cost-effective alternative to traditional asset inspection methods such as helicopters and ground vehicles.</span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 12px;">However, drones are not simply replacing existing methods. Their agility allows them to offer visualisation and data analysis that existing methods cannot compete with. For example, satellites are limited by their orbit and weather can disrupt the accuracy of the images they provide. An engineer would have to assemble scaffolding to physically access a potential problem.</span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 12px;">Scientists now claim that sophisticated sensors are developed enough and small enough to be mounted on UAV systems. As well as capturing high resolution visual data, drones can be equipped with other sensors to monitor pipelines, such as thermal imaging or ultrasound inspection.</span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 12px;">Challenges for take off</span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 12px;">Companies wanting to adopt this technology must also make sure they understand the evolving regulatory environment. Those that already use aviation, for example with helicopters, are probably in a better position to confront this hurdle due to their existing knowledge of aviation regulation.</span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 12px;">Beyond visual line of sight (BVLOS) is among the most discussed things in the drone industry. This refers to where a drone is operating beyond the pilot’s line of sight. BVLOS activity will be necessary to enjoy the full benefits this technology could offer for asset inspection of pipelines, but in some countries it is not permitted.</span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 12px;">In the USA, for smaller drones flying below 400ft above ground level (AGL), BVLOS is currently not permitted without the necessary authorisation from the Federal Aviation Administration (FAA). To navigate around this restriction an FAA waiver is required. According to some research, 99% of waiver applications fail.</span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 12px;">The restrictions are different when you enter different airspace classifications (those above 400ft AGL). For pipelines that traverse national boundaries, these regulatory issues become even more complex.</span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 12px;">Another consideration many businesses must make is what business model to adopt. In its guidance for the industry, the American Petroleum Industry outlines three alternative models.</span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 12px;">Although the technology is constantly improving, there are limitations that are relevant to their potential for surveying pipelines. The limitations of the batteries that power the vehicles gives rise to range anxiety, a problem that is more significant for pipelines that cover considerable distances. It is likely the industry will focus on using drones for inspection of oil rigs and other infrastructure before taking on the challenge of vast pipelines.</span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 12px;">Something to bear in mind</span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 12px;">If maintenance engineers are to exploit the benefits of UAV technology, keeping the drones in tip-top condition will be essential. Understanding the maintenance needs of these vehicles will be important for those companies who adopt the internal model referred to above. Engineers will need to be quick to acquire fresh expertise in this area.</span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 12px;">Maintaining and replacing the bearings in drones will be a critical part of this. Many oil installations face significant risks from corrosion. Bearings too, need protection from corrosion. If your drone is operating in an environment where this risk exists, speak to a reputable supplier such as SMB Bearings for the best information on bearing choice for specific applications.</span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 12px;">The buzz surrounding drones is only set to grow and their use in monitoring and maintaining oil installations will allow the oil industry to improve worker safety, reduce the time taken to complete key maintenance tasks and realise substantial cost savings. If operators are thinking of adopting an unmanned aerial vehicle programme to monitor their assets, they should consider the benefits of partnering with a reliable supplier of high-quality precision bearings to help keep their drones in the air.</span></p><p><br/></p>
