This paper will present a novel concept for remote inspection and maintenance operations on next generation partly unmanned offshore oil platforms. The concept is presented throughthe design of a robotic lab facility for automated and teleoperated inspection and maintenance operations by robot manipulators - ranging from simple inspection tasks to advanced maintenance operations. The lab facility is built around two cooperating robot manipulators equipped with sensors measuring temperature, vibrations, gas concentration and sound, and that automatically changes between tools to operate valves, exchange batteries in wireless sensors and to manipulate objects and the integrated process equipment. An interface allow users to startautomated inspection rounds where sensor data are collected, analyzed and compared to the normal operating conditions, and alarms are generated if deviations are detected. Users may alsoplan new operations in a virtual environment before executing them, or remotely control the robots through a number of control interfaces. Live video feeds and stereoscopic vision is availableto aid the operator during remote operations. A model-based collision avoidance system ensures that both automated operations and unplanned operations are verified before and during execution, and ensures safe operation of the robots. The paper will present results from the lab facility to illustrate the functionality of the remote inspection and maintenance concept, and demonstrate how remote operators may start automatic inspection and maintenance operations, plan new operations in a virtual environment, or directly control the remote facility onshore A Robotic Concept for Remote Inspection and Maintenance on Oil Platforms
