This challenge led to the creation of the first surface robot capable of operating autonomously on oil and gas sites by 2017, with the overarching goal of simplifying operations and reducing human exposure to hazardous environments. The long-term vision is for new oil and gas platforms to be operated by autonomous robot fleets by 2030, further reducing risks for human personnel.

The Inspection Robot: Eyes, Ears, and Nose

Building on the success of the ARGOS challenge, TotalEnergies, in partnership with Taurob and NZTC (Net Zero Technology Center in Aberdeen), launched an autonomous inspection robot project in 2018. This robot is ATEX certified, meaning it is approved for use in explosive atmospheres, a critical requirement for oil and gas facilities. The Inspector-robot is equipped with an array of sensors that allow it to perform various tasks, including anomaly detection (such as gas leaks and fires), recording images and audio data, monitoring temperatures and other parameters, and conducting 3D acquisitions. Extensive qualification and demonstration tests have been performed since its development concluded in 2020. It began operations at the Shetland gas plant, where two robots performed inspection rounds to monitor process module parameters. Between 2020 and 2022, it was deployed on a North Sea platform in a more complex environment, confirming the possibility of controlling and guiding two robots from an onshore control room. Further tests are ongoing in challenging hot and humid environments in the Middle East, including an offshore platform near Abu Dhabi and on Halul island in Qatar. The year 2022 was pivotal, shifting the nature of pilots from robotic demonstration to qualification in new operating modes. In 2023, a highly complex six-month pilot commenced on Pazflor (Angola), involving two autonomous robots and two ATEX charging stations operated by on-site personnel. These robots regularly inspect some 1,700 checkpoints across two separation modules, with instructions directly supplied by a modified planning and maintenance tool. This marks a significant stride for West Africa, demonstrating a comprehensive robotic ecosystem including ATEX robots, charging stations, a robotic supervision system, and Artificial Intelligence, all integrated securely within existing information systems.
