The Compatt 6s and ROVNav 6s will be Sonardyne’s latest ‘plus’ hardware platform (6+), engineered to unlock the full capabilities of Fusion 2.Built from the ground up, with ease of use and operational efficiency in mind, Fusion 2 software offers a seamless environment in which surveyors can perform all of their LBL, SPRINT INS (inertial navigation system) and sparse (INS-aided) LBL operations. When used alongside 6+ hardware, Fusion 2 offers the ability to

3D Sonar Used in Fishery Research

fishery surveys is suitable for sampling bottom-dwelling species but not well-suited for accurately assessing pelagic species.Marine technology firm FarSounder said its 3D-Sonar will allow researchers to detect and assess the fish in the sonar imagery as part of the fisheries project. Using coordinated ground-truthing methods, it is expected that the results from the project will help improve current food web models and local Rhode Island fisheries management.For this project, FarSounder is collaborating with the University of Rhode Island (URI) and the Rhode Island Department of Environmental Management

New Tech for Wind Blade Inspections

main approaches to inspecting wind blades, Paquette says. The first option is to send someone out with a camera and telephoto lens. The inspector moves from blade to blade snapping photos and looking for visible damage, like cracks and erosion. The second option is similar but instead of standing on the ground the inspector rappels down a wind blade tower or maneuvers a platform on a crane up and down the blade.“In these visual inspections, you only see surface damage,” Paquette says. “Often though, by the time you can see a crack on the outside of a blade, the damage is already quite

and clays to rock in ultra-shallow, beach approach work or deep water.The CBT2400 is the latest addition to SMD’s existing burial tractor range and is an evolution of the CBT2100 which was last delivered in 2011. The CBT2400 is designed to provide a reliable solution for protecting cables in hard ground with interchangeable cassette tooling, SMD said. The tractor provides a remote-control platform with a range of trenching tools for different ground strengths; the tool consists of a hard ground cutting boom, rear jetting tools for lowering the power cable and next generation eduction tools for spoil

BlueComm 200 UV can provide this link, securely and covertly.With BlueComm 200 UV, extra-large unmanned underwater vehicle (XLUUV) platforms will be able to operate and communicate with other vehicles or with ground stations at choke points, helping to monitor, detect and prevent incursions from foreign agents, all while remaining covert.Practical examplesIt’s not all about covertness, recently we achieved quite the opposite. The technology was out in the field, being used to achieve a world first. Working

quality will be insufficient. That's simply not an option."According to Aidan Marchand, who oversees the technical execution of the project from the Vattenfall side, the team was already aware that the North Sea does not always offer the best conditions – weather and otherwise – for ground surveys."That's why our original plans allowed for several weeks when we would not be able to collect any data."Due to the turbulent weather, the research ships have to make the most of the calm periods in order to catch up. "Then the crew collects data around the clock, day and

.The use of unmanned vessels offers significant benefits including safety with operators remaining onshore, efficiency with 24/7 operations and environmental with ultra-low emissions which together leads to significant economic savings.Duncan Mallace, Managing Director of 4DOcean, said, “These were ground-breaking surveys as both ASVs were operated independently, without a mothership but with monitoring and watch-keeping from the shore 24/7. The unmanned vessels were used to map the shallow uncharted waters, while a manned vessel completed the deeper areas. A normal single survey team was used to

It looked at connectivity and reef effects and aimed towards being able to model eco-systems to predict the effect of man-made structures.While Phase 1 helped progress the understanding of the effects and connectivity of man-made structures in the North Sea ecosystem, some ground truthing is needed, says Heard, and more data is needed across the basin.The Phase 2 work hopes to address some of these concerns. Its main objectives are to, one, understand the role of man-made structures as an inter-connected hard substrate network across the North Sea, two, understand the role
