Robotics are revolutionizing the transformation of many industries across the globe; one is oil and gas industry. The industry has lately been under a huge pressure to stay efficient, safe, cost competitive and reliable. Therefore, new technologies and solutions have been a focus of companies in the industry to optimize and move on from their conventional practices to more efficient and reliable methods. Autonomous robotic vehicles equipped with advanced sensors, cameras & tools can perform complex and sophisticated maintenance and inspection tasks such as robotic tank cleaning & inspection, robotic UT inspection for elevated assets & robotic coating removal vehicle. These robots have gained the company benefits in both directly & indirectly reducing the cost and time and more efficient and comprehensive outcome. Finally, safety & environmental impact has been an optimum benefit out of using these robots which can easily be navigated into a hazardous confided spaces and high elevated assets. This paper presents a comparison between advanced robotics and conventional methods for inspecting and maintaining static assets from an operator's (Petroleum Development Oman) perspective.
