Successful Sea Trials with Sonar and Pressure Tolerant Batteries

June 1, 2021 Kraken Robotics has announced that Dive Technologies recently completed successful sea trials of Kraken’s Miniature Synthetic Aperture Sonar (MINSAS 120), integrated into Dive’s Large Displacement Autonomous Underwater Vehicle (DIVE-LD). The DIVE-LD is also powered by Kraken’s pressure-tolerant batteries. Kraken’s MINSAS is a commercially available off-the-shelf configurable Interferometric Synthetic Aperture Sonar (SAS), which replaces high-end side-scan sonar systems while delivering significantly higher resolution, range and area coverage rates (ACR). The increased range and resolution and associated higher ACR of SAS over traditional systems offer a powerful capability when combined with the long range and endurance of the DIVE-LD.

Large-format 3D printing enables toolless, rapid production for AUVs

The exterior of Dive Technologies’ 19-foot-long DIVE-LD autonomous underwater vehicle is manufactured from nine 3D-printed composite fairings that are mechanically assembled and coated. Photo Credit: Dive Technologies Autonomous underwater vehicles (AUV) are a type of unmanned robotic vehicle capable of traveling underwater without physical connection to or remote control from a human operator. Often outfitted with sensors or cameras, or transporting equipment, AUVs are used in various markets, including defense and ocean-based research. Energy companies have also used AUVs for offshore survey work to monitor existing oil and gas or offshore wind infrastructure, and to investigate areas for new development.
