Abstract This work aims to present the results of a conceptual study of a Normally Unattended FPSO. The search for solutions that enable the operation of a typically unattended production unit, thereby reducing the amount of exposure to risk, has two main fronts: the pursuit of solutions that enhance the integrity and reliability of the unit and the replacement of human intervention with devices that can be operated remotely or function autonomously, including the use of drones, robots and other
