Freedom, a hybrid AUV/ROV system, is the result of a long-term collaborative relationship between Oceaneering,
As a result of this long-term investment and effort, Freedom has now demonstrated to the expert group that it can carry out low altitude inspection and survey on pipelines of different diameters. The vehicle can track pipelines at between 3-5m altitude from the seabed providing high resolution survey data and at 8m altitude for reconnaissance and seabed mapping. Freedom's control software includes specific behaviors to locate and maximize data acquisition value for burial, crossing and freespan events.
To ensure the safety of the vehicle and customer assets, Freedom includes a sophisticated level of obstacle detection, autonomous obstacle avoidance, and general situational awareness. These features allow the vehicle to re-plan its route to avoid detected objects and then to re-engage with the pipeline being tracked once the vehicle has navigated safely past the object.
The initial configuration of Freedom for pipeline Inspection includes outfitting with high specification instruments such as Inertial Navigation System, Laser Scanning System as well as Multibeam Sonar technology to take advantage of Freedom's unprecedented pipeline tracking ability and proximity to the pipe.
Freedom offers customers a new level of efficiency, providing significantly improved and more complete data sets than obtainable via traditional AUV pipeline inspection techniques at a significantly increased speed compared with legacy ROV inspection methods.
