owned by DOF Subsea Norway AS.The aim of the work was to obtain the necessary basis for engineering design services for a bridge over Bjørnafjord in connection with the Ferry Free E39 project. The assignment included high-quality geophysical surveys, (bathymetry, shallow seismic, and side-scan sonar) in order to provide SVV with detailed high-resolution geophysical data in an area approximately 5.5km long by 800m wide.The project was planned as a low logistics shore-based launch of an AUV, supported by the small vessel equipped with a system to provide positional updates to the subsea vehicle

Kraken Debuts New Synthetic Aperture Sonar

A new synthetic aperture sonar (SAS) unveiled this week by Kraken Robotics Inc. is designed to provide ultra high definition seabed mapping with superior area coverage rates, according to the developer."Kraken’s latest development, the AquaPix MINSAS-240 sensor, has been designed to advance the state-of-the-art in seabed mapping for both high-speed towed systems and large diameter unmanned underwater vehicles (LDUUVs)," explained Kraken's President & CEO, Karl Kenny.The 6,000-meter-rated MINSAS-240 SAS is available now and ready for integration on a variety of unmanned underwater

longer endurance missions, reduced number of launch and recoveries and flexibility for weather windows. In addition, Ocean Infinity’s team of surveyors and data processors have been extremely impressed with the quality and resolution of the imagery from Kraken’s synthetic aperture sonar (SAS). With Kraken’s MINSAS sensors integrated on the Hugin AUVs, the ultra-high definition of the imagery provides an invaluable tool for identification of seabed targets and seafloor features.”Kraken also announced Tuesday that its Board of Directors has approved the issuance of 500

UKHO Contracts with TCarta

U.S. Multiple new reefs have been discovered by TCarta using this satellite derived approach at the start of this project. The islands and surrounding environs have not been mapped in their entirety since the late 1800s. Acquiring bathymetric data and habitat classifications using traditional ship-borne SONAR or airborne LiDAR are prohibitively expensive, logistically challenging and come at far higher cost and timeframe than a satellite-based solution

Requirements include terrestrial LIDAR and underwater sonar sensors that will be used for inspections of piers and wharfs to identify structural integrity.The MARV II represents one piece of a multi-agency initiative to develop and demonstrate a full suite of port repair technologies. By utilizing both off-the-shelf and transformative technologies, this initiative

the UK’s first.The first show attracted some 600 people, exhibitors and visitors, including British Labour politician and Minister for Technology, Tony Benn (pictured right opening the inaugural evel). Among the show’s first visitors was Marty Klein, who was instrumental in bringing side scan sonar technology to commercial market. “There was a lot of excitement about the oceans,” he says. “Cities under the sea were going to feed the world. People were building manned submersibles to go exploring in the deep. Aerospace companies were building submersibles, like Lockheed, North

. In particular the Mission Oriented Operating Suite (MOOS) was launched at the MIT AUV Lab in the early 2000s. Other technical developments undertaken were experiments with early acoustic modems and Doppler velocity logs (DVLs). Payload systems were also integrated and evaluated. Early digital side-scan sonars were an important step toward today’s survey AUVs. The first integration of a sub-bottom profiler on an AUV was also completed by the MIT AUV Lab during its first decade.An Odyssey AUV equipped with an early sub-bottom profiler (Courtesy J.

Sonar Assists Deepest Solo Sub Dive

Trench -- the deepest solo human submersible dive ever.It goes without saying that state-of-the-art subsea technology was key to the mission's success. The submersible, a Triton 36000/2, features a 90mm thick pressure hull and is the first commercially certified full ocean depth.New multibeam sonar technology from Kongsberg Maritime also played a big part in the feat. Utilized for precision mapping, the Kongsberg EM 124 was installed aboard the DSSV Pressure Drop to produce seafloor bathymetry to map the trench."[The EM 124] produced digital 3D renderings of the sea floor that were used

The number of boats in the area meant there were many cellphone videos, making the general location of the plane easier to pinpoint.Working to find the sunken aircraft, Parker Marine Salvage contacted Steve Van Meter of Van Meter Consulting to help pinpoint the exact location.An extensive sidescan sonar mission, lasting several days, had identified 75 potential targets on a seabed littered with old debris from years of dumping. Van Meter studied these targets and identified the one that had a very high probability of marking the aircraft.Once on the water, the team made quick work of locating the
