Racing to the Bottom: Seabed Warfare Brings Threats, Opportunities
United States employed highly specialized manned submarines to tap Soviet undersea cables in the Barents Sea and Sea of Okhotsk.Image courtesy VoyisToday, there are 785,000 miles (1.2 million kilometers) of transoceanic undersea cables crisscrossing the globe, transmitting 97% of global voice and data communications, the disruption of which could wreak havoc on everything from financial transactions to military operations. Although not immune to fishing trawlers and seismic instability, seabed infrastructure has for decades enjoyed a veil of invulnerability to targeted threats given its challenging operating

Energy @ Sea: Powering Up in the Blue Desert
10 challenges—goals for regional, national and global participants to work towards for positive, collective impact on our oceans. Included in the 10 are ocean-based solutions for climate change, expanding the Global Ocean Observing System, creating a digital representation of the sea, and access to data and technology across all marine stakeholders. These and others on the list depend on collecting increasingly more ocean data. While technology to monitor marine systems is rapidly adapting and expanding, it surfaces new issues such as offshore energy generation and storage to support sensors, operating
EC-OG's Subsea Battery For "World-first" Autonomous Offshore Power Trials in Hawaii
world-first demonstration project alongside our client C-Power and other project partners.“This is a crucial project for the industry which will demonstrate the integration of a selection of novel subsea technologies to deliver a reliable source of power as well as real-time over-the-horizon data communications. The learnings from this project will be significant for the development of the blue economy and further decarbonization of offshore operations globally.”Designed for the harsh subsea environment, the Halo system is a modular and scalable battery storage solution and gateway for renewable
Seabed Power: Waves Used to Power Up Sabertooth Autonomous Vehicle
Converted energy from waves powering a Saab Seaeye Sabertooth autonomous vehicle operating in seabed residency mode is a renewable energy breakthrough being put to the test. C-Power’s SeaRAY Autonomous Offshore Power System (AOPS) provides offshore power, energy storage, and real-time data communications for resident marine systems.Trials of the Sabertooth residency concept will take place at the U.S. Navy’s Wave Energy Test Site (WETS) in Hawaii and last 20 days. The SeaRAY AOPS and other static assets will remain deployed for six months. The Sabertooth, owned by Hibbard Inshore, and

and vehicles, and eventually all the way up to entire cities.The Resen Waves Smart Power Buoy is designed to harness the constant movement of waves to power autonomous machinery (AUVs) and instruments in the sea with clean, renewable, continuous energy while facilitating real-time, uninterrupted data communications.Resen Waves’ Smart Power Buoy sits at the crux of an important crossroads and that's renewable energy and the emerging need to provide power at sea. While working in the sea is never simple, Roland Boysen, CCO, contends that his company is cracking the code on generating power from

, connected and resident technologies. It is designed to support unmanned offshore activities, including subsea vehicles, sensor packages, and operating equipment.“The ocean is a power desert,” said Reenst Lesemann, CEO of C-Power. “Providing reliable power and real-time data communications through an AOPS is critical to unlock the full potential of the marine economy. The SeaRAY delivers these capabilities and enables a future of cheaper, safer, cleaner, more connected offshore operations.”The sea trials will begin later this year at the Navy’s Wave Energy Testing

of uncrewed surveys from shore-based stations.” The proven ability to conduct remote survey operations with USVs has many beneficial applications across the offshore sector. For example, critical tasks such as trans-ocean cable route surveys, needed to meet the increase in demand for data communications, can be completed without risk to personnel and with significant savings on mobilization and operational costs when compared to executing the same task with crewed vessels. UK Space Agency Chief Executive, Graham Turnock, summed up how USVs are set to redefine offshore operations: &ldquo
Ocean Power Technologies Launches Hybrid PowerBuoy
Ocean Power Technologies, an ocean energy technology developer, has expanded its offering with the latest product called the hybrid PowerBuoy.The hybrid PowerBuoy is a buoy that offers remote power for subsea and topside applications, data communications, and a nominal 1.5-megawatt-hours of energy storage. While OPT is known for its moored floating buoys - such as OPT PB3 PowerBuoy - that harvest and store wave energy, this buoy is a hybrid, meaning it doesn't necessarily depend on waves to generate power, as it utilizes solar panels and a Stirling backup engine to power topside or subsea
