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.

AquaPix – A Low-Cost Interferometric Synthetic Aperture Sonar for AUVs: Sea Trials and Results

August 12, 2013 via – UUST 2013

Abstract— Kraken Sonar Systems Ltd, based in St. John’s, Canada, produces an Interferometric Synthetic Aperture Sonar (InSAS) system, suitable for integration on a wide range of AUVs and towed platforms. In 2012, Kraken entered into a Cooperative Research and Development Agreement (CRADA) with the Naval Undersea Warfare Center (NUWC) in Newport, Rhode Island. This paper seeks to present a background of Kraken’s InSAS technology, and detail the results of the CRADA. The primary focus of the paper (and the CRADA) is the integration and testing of an AquaPix InSAS on NUWC’s medium-sized 12.75” diameter REMUS600 AUV, manufactured by Hydroid. Kraken designed a payload section for the R600, and assisted NUWC operators with integration onto the AUV. After a very short integration, the resulting integrated SAS-AUV was able to produce ultra-high resolution 3cm imagery and co-registered 25cm bathymetry with no vehicle re-tuning necessary. The main conclusion from this trial was objective evidence that SAS is achievable on medium sized AUVs without extensive tuning or additional control planes.
