DARPA BAA 13-39 (Hydra)

August 22, 2013 via - DARPA

The Hydra program will develop and demonstrate an unmanned undersea system, providing a novel delivery mechanism for insertion of unmanned air and underwater vehicles into operational environments. Situated underwater, Hydra will use modular payloads within a standardized enclosure to enable scalable, cost-effective deployment of rapid response assets and will integrate existing and emerging technologies in new ways to create an alternate means of delivering a variety of payloads close to the point of use. The Hydra program seeks to develop
and demonstrate initial examples of air and undersea payloads while leaving open the potential for accommodating additional payloads in the future.

The rising number of ungoverned states, piracy, and proliferation of sophisticated defenses severely stretches current resources and impacts the nation’s ability to conduct special operations and contingency missions. The Hydra program represents a cost effective way to add undersea capacity that can be tailored to support each mission. Hydra’s communications suite could allow synergistic function with manned platforms, thus increasing their effectiveness, or
could allow remote control from over-the-horizon. Technologies are intended to be adaptable to multiple delivery options, including airborne, surface, and subsurface. The Hydra program will enable other new capabilities not currently performed from undersea.

Slocum Glider Expanding the Capabilities

August 12, 2013 via - UUST

Teledyne Webb Research (TWR) provides here an overview of the latest Slocum G2 features including the hybrid thruster, increased buoyancy pump displacement, new sensor suites, and an update on the energy harvesting Slocum Thermal E Twin. Three main mission objectives will be reviewed: polar regions, acoustic data telemetry, and long duration transects approximating the course of the Challenger expedition of 1872-76.

Sabertooth a Seafloor Resident Hybrid AUV / ROV System for Long Term Deployment in Deep Water and Hostile Environments.

August 12, 2013 via - UUST 2013

Increasing use and complexity of subsea installations has put focus on the costs of maintaining these systems. In addition, access to these systems is sometimes limited by adverse weather and ice conditions. Conventional methods for intervention, maintenance and repair (IMR) using surface ships and ROV’s are very expensive furthermore response and mobilization times can be fairly slow.

To address this Saab Underwater Systems has developed a hovering Hybrid AUV/ROV system to remotely perform IMR without or strongly reduced need for a supporting ship. This system is based on the Double Eagle SAROV, a hovering Hybrid AUV/ROV in production for the military market and proven components from Saab Seaeye ROV product range.

This paper will present the Seaeye Sabertooth subsea resident AUV/ROV system, its concept of operation, design and the cooperation project between Saab and Aker Solution. It will also present the ongoing Sabertooth tests and trials conducted together with Tecnomare and Chevron.
