A newly granted patent (Publication Number: US12006779B2) reveals a sophisticated system designed to efficiently make or break a riser joint. The system comprises a robotic system with one or more robotic arms, each equipped with six degrees of freedom, and riser-connection manipulation tools featuring lidar technology with laser light sources. These tools are adept at manipulating various riser connections such as riser bolts, breech locks, or latching dogs. The control system, including a robot controller, enables precise positioning of objects based on reflected laser light, allowing the robotic arms to perform tasks accurately.

Furthermore, the system includes multi-function tools capable of a range of actions like placing or removing riser bolts, manipulating different components, and applying predetermined torque. The torque wrench tools, with sockets and hydraulic torque mechanisms, ensure the secure fastening or loosening of riser bolts without human intervention. The integration of cameras for object recognition and a quick-change system for tool replacement enhances the system's efficiency and adaptability. Overall, this patented system showcases advanced robotic technology tailored for the specific requirements of riser joint operations, promising increased precision and automation in the industry.
