COAST Announces Four Successful Clean Energy Innovation Challenge Participants
(ACET) researchers to support their development goals.Ascent Systems Technologies is adapting its Autonomous Environment Monitoring and Surveillance (AEMS) platform into AEMS-COAST, a rugged, modular clean-energy unit. The system integrates renewable generation, storage, smart power management and communications to operate autonomously. The company will reconfigure and enhance the system for long-term deployment in harsh coastal and marine environments.Cleohydron Innovation Inc is developing “Hydrogen at the Edge,” a clean hydrogen production system tailored to remote coastal facilities that
Researchers Improving Collaboration Between Divers and AUVs
?" Then, the diver can respond, "Yes, you've got it right, or no, look over here in the image to improve your classification," Miller says.This feedback loop requires an underwater acoustic modem to support diver-AUV communication. State-of-the-art data rates in underwater acoustic communications would require tens of minutes to send an uncompressed image from the AUV to the diver. So, one aspect the team is investigating is how to compress information into a minimum amount to be useful, working within the constraints of the low bandwidth and high latency of underwater communications
A Breath of Fresh Air: USVs Map Hypoxia in the Gulf
it more versatile and robust in its data collection abilities. "Specifically for this one," Boeschenstein added, "the big development effort on our side was the winch and being able to support profiling down to the seafloor. Throughout the course of the project, layering on additional communications like the Starlink Mini was a big addition from when we first started.""It's so versatile as far as what we can put on it. We tested cameras, we tested some collision avoidance tech—a lot of different things while we ran this hypoxia mission. That just goes to show you how
The Politics of a Subsea Data Cable Link to Antarctica
the highest density of research stations, which is being developed through funding from Multilateral Cooperation Center for Development Financing and CAF Development Bank of Latin American and the Caribbean.These cables would facilitate greater research data transfer that is not reliant on satellite communications.As the Southern Ocean, including the climate-critical Antarctic Circumpolar Current, remains less researched than other bodies of water, a sensor-equipped cable would also provide a valuable platform for sustained seafloor observations and scientific data generation.However, such cables could
On-Demand Ocean Bottom Node: A New Era in Deepwater Seismic Monitoring
optical interface to interrogate the OD OBNs, as developed under a separate ANP program sponsored by Shell.This AUV data harvesting approach eliminates the need for node recovery, reducing vessel time, operational complexity and associated costs.Key Sonardyne technologies include wireless acoustic communications, required for long range recording control and node clock time offset measurement, and Sonardyne’s BlueComm extremely high-speed optical communications for short range data harvesting to a nearby AUV or remotely operated vehicle (ROV).ResultsOver 2,000 days of trials of pre-production nodes
LEO Satellite Networks: Supporting Maritime Safety, Efficiency and Innovation
and shore-based teams with greater situational and operational awareness throughout voyages.However, unlike many onshore industries that are already benefitting from improved data availability, the maritime sector still faces significant barriers, primarily due to slow and often unreliable at-sea communications. More timely access to data is particularly critical to translating data-driven insights into real-world benefits and fostering industry innovation. To enhance vessel connectivity and overcome this challenge, there has been growing interest in the use of low Earth orbit (LEO) satellite networks
Intruder Alert: Ports Face a Range of Underwater Threats
an important component of this deterrent posture, providing a visible presence that discourages unauthorized activity, as well as a rapid response capability. Surface operations may also contribute to underwater surveillance, as radar, EO/IR sensors, or human observers might detect UUV wakes or communications masts, particularly during calm water conditions.Physical barriers provide another important deterrent. Floating security booms are widely used to restrict access to sensitive areas of ports and naval bases. These systems typically consist of surface pontoons connected by cables with mesh netting
Marine Technology TV Discusses Latest ROV Trends
, logistics and lifecycle expectations.”User experience holds enormous weight for customers shopping for underwater vehicles. Systems need to be efficient, customizable and ultimately useful for the desired work. “Customers want systems that can handle uncertainty, operate with limited communications, and integrate smoothly into broader maritime forces that include crewed ships, aircraft and other unmanned platforms,” said Fotheringham. “They're also looking for reduced operator burden.”Also in the issue, Amir Garanovic, managing editor of Offshore Engineer, takes a
Cellula Robotics Selects Sonardyne for Long-Range AUVs
positioning technology for its long-range autonomous underwater vehicle (AUV) platforms.The company has ordered multiple Sonardyne SPRINT-Nav X navigation systems - Sonardyne's highest grade and underwater navigation system.The company has also selected Sonardyne’s AvTrak 6 for tracking, communications and mission control. Part of the package/purchase is multiple Sonardyne Ranger 2 Ultra-Short BaseLine (USBL) positioning and communications systems for both AUV end users and demonstration and testing.“Our users need certainty,” says Richard Mills, Cellula’s Chief Commercial
