Hearing the Light: DAS could Revolutionize Subsea Defense
, identification, and localization of threats. Although currently optimized for low frequency detection, DAS does have the capability to detect high frequency emissions as well, such as those generated by vehicle actuators and thrusters, as well as underwater navigation, imaging, and communication technologies. A 2020 MIT study found that small AUVs generate intense emissions in the 15-24 kHz range, which can be 10-45 decibels above the ambient background noise.† A typical DVL emits at anywhere from 400-600 kHz, while SAS emits anywhere from 60-120 kHz. Echosounders emit at high frequencies
USVs Eye Offshore Wind Opportunities
USVs,” says Watson. “For a short duration debris survey, you send a DriX. For construction monitoring and regular surveys at a large offshore wind farm or one far offshore you mobilise a field resident Saildrone Voyager. These systems are well equipped with survey sensors and communication technologies, allowing data to be transferred to shore and, where possible, particularly during operations and maintenance, we can do this via the client provided 4G networks now built into wind farms.”However, the next technology leap is needed, Watson says, for these vehicles to go beyond bathymetry

world’s best 5G network and technologies.”“We have now secured an optimal research environment to make a leap in the area of autonomous navigation ship technologies by combining Samsung Heavy Industries’ autonomous and remote navigation system and SK Telecom’s 5G communication technologies,” said Shim, Yong-Lae, Vice President of SHI Ship & Offshore Research Institute
EOMAP Wins Funding for Next-Gen Satellite-Derived Bathymetry
new funding will allow EOMAP to push ahead with new SDB procedures based on high-performance scientific computing employing field programmable gate arrays (FPGAs). FPGAs are semiconductor devices that can be programmed by the user. They are currently used in applications such as automotive and communication technologies. Their big benefits are their higher speeds and lower energy consumption compared to normal processors. However, the optimal interaction of FPGA and CPU processing requires deep knowledge of scientific programming.“By combining FPGAs, physics-based data analytics and modern machine
Partners Set Out to Cut Offshore Emissions
consumable information to decision makers; from the vessel’s chief engineer to the chief operation officer based shore-side.“The partnership is focused on building a platform for intelligent efficiency, made possible only through the integration of operational, information and communication technologies,” said Eirik Mathiesen, Director of Energy Products Integration, Kongsberg Maritime. “Encompassing IoT, new smart sensors on board will stream accurate data to the cloud-based DSS, where deep analysis with intuitive presentation and application will drive equitable and predictable

more stringent LINZ specification. An EM 2040P will be operational on Kongsberg's Oceanology demo boat, the Northern Wind, which will be running test surveys open to show visitors in the Victoria Dock. Demonstrations, which also feature a number of new and existing survey, positioning and communication technologies can be booked on the Kongsberg Oceanology. Designed for any high resolution mapping and inspection application, the portability of the new EM 2040P enables straightforward delivery and installation on small vessels of opportunity. A key aspect of the system is that it features
The World’s Cold Ocean Lab
Simulation (CMS) boasts the largest suite of marine simulation technology in North America. The university is a production line for wave after wave of graduates with cold ocean expertise, including ship operations, vessel design, ocean instrumentation and equipment, marine information and communication technologies, ocean mapping, and underwater technology. MUN is also home to the Genesis Center, a small business incubator that helps to grow business startups – including ocean technology companies – and advance technology developed at an academic level into commercialization.
