AUVs are now relatively widely used by both the oceanographic research community and the defence sector, where their ability to quietly operate for long periods deep beneath the surface and to return detailed data from the seabed, makes them ideal for a range of applications. But now, dramatic mprovements in capability, coupled with our insatiable demand for energy, are driving a growing use of the technology in the offshore energy industry.
The trend was one of the key talking points at London’s recent Oceanology International conference (March 2014), where manufacturers, survey companies and energy firms all pointed to the growing use of AUVs for a range of subsea survey and inspection tasks. Indeed, Tom Hiller, a senior engineer from Teledyne Gavia — one of the leading AUV manufacturers — told The Engineer that operators are now even beginning to specify AUV solutions in contracts.
The technology certainly has some compelling advantages: AUVs are faster than the remotely operated tethered vehicles (ROVs) that are widely used in the offshore sector. And, because they’re able to operate autonomously under their own power, are less of a drain on resources: operators can put them in the water, leave them, and go off and do something else. But it’s the quality of the data they can gather that’s really driving their use. Able to fly metres above the seabed — or close to subsea installations — AUVs enable operators to rapidly deploy a range of high-frequency sonar systems and cameras to gather detailed subsea data.
What’s more, the technology also enables operators to access areas that are off-limits to other equipment, an attractive capability for an industry that’s moving into ever-more remote environments.View Full Article

The Woods Hole Oceanographic Institution has been awarded funds by the National Science Foundation to develop a tethered robotic underwater vehicle for under-ice exploration by 2014. By employing a novel light-weight tether for data-only communications, the vehicle will provide the U.S. Polar Research Community with a capability to tele-operate, under direct real-time human supervision, a remotely-controlled inspection and survey vehicle under fixed ice at ranges up to 20 km distant from a support ship or other deployment site. Physical tethering of an underwater robot is required to provide low-latency, high bandwidth control and real-time data return. The vehicle will enable exploration and detailed exploration in under-ice environments through the use of high-definition video coupled to a suite of chemical and biological sensors. Long-range light-fiber tether technology provides the high bandwidth link necessary for real-time control under the direction of the science party which AUVs cannot meet.View Full Article

Unmanned systems continue to deliver new and enhanced battlefield capabilities to the warfighter. While the demand for unmanned systems continues unabated today, a number of factors will influence unmanned program development in the future. Three primary forces are driving the Department of Defense’s (DoD) approach in planning for and developing unmanned systems.
1. Combat operations in Southwest Asia have demonstrated the military utility of unmanned systems on today’s battlefields and have resulted in the expeditious integration of unmanned technologies into the joint force structure. However, the systems and technologies currently fielded to fulfill today’s urgent operational needs must be further
expanded (as described in this Roadmap) and appropriately integrated into Military Department programs of record (POR) to achieve the levels of effectiveness, efficiency, affordability, commonality, interoperability, integration, and other key parameters needed to meet future operational requirements.
2. Downward economic forces will continue to constrain Military Department budgets for the foreseeable future. Achieving affordable and cost-effective technical solutions is imperative in this fiscally constrained environment.
3. The changing national security environment poses unique challenges. A strategic shift in national security to the Asia-Pacific Theater presents different operational considerations based on environment and potential adversary capabilities that may require unmanned systems to operate in anti-access/area denial (A2/AD) areas where freedom to operate is contested. Similarly, any reallocation of unmanned assets to support other combatant commanders (CCDRs) entails its own set of unique challenges, which will likely require unmanned systems to operate in more complex environments involving weather, terrain, distance, and airspace while necessitating extensive coordination with allies and host nations.
The combination of these primary forces requires further innovative technical solutions that are effective yet affordable for program development. The purpose of this Roadmap is to articulate a vision and strategy for the continued development, production, test, training, operation, and sustainment of unmanned systems technology across DoD. This “Unmanned Systems Integrated Roadmap” establishes a technological vision for the next 25 years and outlines actions and technologies for DoD and industry to pursue to intelligently and affordably align with this vision.View Full Article
