sonar with gapfill featured by the BlueView MB2250. Inertial navigation will be provided by the PHINS C5 (iXblue) inertial navigation system (INS), aided by a 600kHz Pathfinder DVL (Teledyne RDI. Additionally, the AUVs will be equipped with Cnode modems (Kongsberg Maritime) for USBL tracking.With the imaging and navigation sensors listed above, the AUV will be able to gather high resolution, accurately navigated, sonar images while remaining submerged for several hours of continuous operation at survey speeds up to five knots. Each Gavia AUV will be delivered with several field-replaceable battery modules

data libraries that together cover all the significant hydrocarbon provinces around the world. The new joint data library will comprise nearly a million kilometers of uniquely complementary data, including many areas of genuine broadband seismic, that have substantial opportunity for integration and reimaging," the companies said.The companies said that ION's latest imaging technology and PGS' broadband 2D GeoStreamer offering, would lead to the production of "enhanced deliverables with higher resolution and greater spatial coverage, offering deeper insights and more reliable pre-stack

Staying Vigilant On and Beneath the Waterline

requirement of an FLS means delivering the same type of information many hundreds of meters ahead of the host platform, often in shallow water. We need to ‘forward look’ and still provide navigationally relevant terrain and object detection data. That’s not easy.“It means imaging both the surface and the seafloor and anything in-between (two highly reflective surfaces). It means handling high levels of multipath interference caused by multiple reflections off these two interfaces. We have to deal with increased levels of ray-bending, associated with propagation through a

Fugro Says Completes Middle East's First Uncrewed Geophysical Route Survey

data across a survey area some 40 km out from the coast of Abu Dhabi. Fugro did not say who the client for the survey was."The results of the fully autonomous geophysical shallow-water route survey comprised conductivity, temperature, depth and salinity (CTDS) profiles, bathymetry data, seabed imaging, sub-bottom profiles, and ferrous object detection such as pipes etc," Fugro said.According to Fugro, the efficiency gains and material reductions from using Fugro’s remote and autonomous solution, rather than a conventionally mobilized and crewed survey, included reduced HSSE exposure

kept these vehicles from being used for critical EOD, Submarine, and Naval Special Warfare missions.What are the specific tech attributes of your system(s) that you have found to be particularly attractive to the defense sector (please be specific)?The Iver4 carries the highest performing navigation and imaging sensors available, while using swappable battery chemistries that meet flexible mission needs. The clean power architecture and signature mapping of the UUV ensure that the highest quality data is produced from the onboard imaging sensors. The unique, wet-mateable sections allow payload changes

LOC Offering 3D Digital Inspections

enabling remote advanced surveying by use of aerial drones and remotely operated underwater vehicles (ROV), which will be applied to a range of assets both onshore and offshore.Survey data results are collated and reproduced in 3D imagery, by using high resolution visual, thermal, LIDAR and SONAR imaging, to create a virtual walkthrough of vessels and both offshore and onshore structures. The imaging will reveal areas that previously, in-person inspections were not able to reveal, which will allow companies or individuals to make better informed decisions when it comes to risk assessment, asset

Klein Debuts Nadir Imaging Sonar for UUVs

Klein Marine Systems offers a Nadir Imaging Sonar for both the commercial and military unmanned vehicle markets. The μMA-X is designed to be scalable and modular, integrating easily to most AUV/ROV vehicles. The system uses Klein’s μEngine a compact, low-power architecture which uses Klein BLUE technology to provide imaging performance.Traditional side scan sonar systems suffer from a nadir gap in the center of the image directly under the path of the vehicle. The μMA-X system fills the gap and, when paired with conventional side scan, eliminates the need for overlapping survey lines to
