, 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

possible and maintain high data throughput.  This demonstrates the value of the DOLPHIN Comms technology in enabling networks of moving nodes, like swarms of UUVs.A more concrete example of the benefits can be seen by considering the case of two UUVs attempting to communicate using Assured Data Communications.  This is depicted in Figure 3. Traditional half-duplex approaches require an acknowledgement from the receiving node for each packet that is sent and take 20 seconds, in this example, to deliver a data message between UUVs. But using a DOLPHIN full-duplex approach can deliver up to a

into the Gulf of Mexico where we believe there exists significant need for cost-effective remote offshore power and communications.”OPT's PowerBuoy and subsea battery solution product lines, along with its support services, provide clean and reliable electric power and real-time data communications for remote offshore and subsea applications.Kirby said the company sees big opportunities in the U.S. Gulf. “The Gulf of Mexico is the largest oil field decommissioning market in the world with more than 9,000 wells that require plugging and abandonment. Many of these wells are in deep

integrated in little chips with a particular function, and logic design stood shoulder-to-shoulder with old school discrete electronics.  The new integrated circuits ran on low voltages with minimal current.  Instruments started to shrink as a result, while their ability to resolve and record data intensified.  The golden age of mechanics was having some of its realm re-assigned to the expanding world of electron flow devices. Some favored ‘pressure protected’ circuits, others favored ‘pressure compensated.’ Each had their lists of what worked and what didn&rsquo

place on the February 15th at Delta SubSea (DSS) test tank facility in Houston, Texas and was attended by representatives from Shell, ExxonMobil, Chevron and BP.  Seatooth wireless controllers were integrated with a Seatronics Predator II Inspection Class ROV and a DJI Inspire drone. 2-way data communications between the ROV and the drone were demonstrated while the ROV was submerged in a test tank and the drone flew overhead. “We are helping our customers to drive down costs. Using proven subsea wireless automation deployed by inspection and light class ROVs, we are delivering improved

the way oceans are monitored subsea – especially in remote and difficult to access, harsh environments – through its subsea power harvesting and telemetry systems. A barrier to collecting long term data in these environments is a sustainable supply of power to the instruments and data communications infrastructure. With the challenges imposed by such environmental conditions one of the only suitable power sources are batteries. Specialized vessels must be used to deploy and recover data from the systems that have exhausted their batteries – a very costly, time consuming, and risky

on projects worth £6million. This has spurred Ashtead on to establish a dedicated Engineered Measurement Solutions Group to focus exclusively on this solutions-based approach to complex applications, including attitude monitoring, vibration and stress monitoring, optical metrology, data communications, engineering data analysis and integrity management. Ross Macleod, technical director of Ashtead Technology, who is heading up the new Engineered Measurement Solutions Group commented: “Ashtead sees a very different future within the offshore sector where cost efficiency is not just
