Unheard Underwater: Covert Communications

of operations and cite secure communication links as a requirement to make this vision happen. 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

started up until now. 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

It recently saw long-standing member Vattenfall produce first power from the European Offshore Wind Deployment Centre (EOWDC) in Aberdeen bay. AREG played an integral part to getting this project off the ground and eventually sold its 25 percent stake in the wind farm to the Swedish energy group in 2016.Jean Morrison, chair of AREG, said, “It is an exciting period for the renewables industry in Scotland and around the world. We’ve seen Scotland producing enough green energy to power the equivalent
