The Push for High Voltage Subsea Cable Systems
One of the biggest shifts in offshore infrastructure revolves around the development of 132kV dynamic cables. These aren’t just wires in the sea they’re the backbone of floating wind farms, remote oil platforms, and future Subsea Technology News grids.
Major players like Nexans and Prysmian have begun producing 132kV cables capable of withstanding the dynamic loads of floating offshore wind (FOW) installations. Traditional cables simply can’t handle the constant motion, tension, and saltwater corrosion that these new applications demand. These new cables are equipped with cross linked polyethylene insulation, advanced metallic shielding, and modular connector heads. This allows for easier maintenance and improved resistance to both environmental stress and electrical overloads.
With the global transition toward increased adoption of FOW systems particularly in Europe and East Asia loating wind cables have become one of the most critical components of subsea power systems
Subsea Technology News Data Collection Enters the Smart Era
Underwater data has traditionally been difficult, slow, and expensive to collect. But things are changing fast. A new wave of innovation is simplifying subsea monitoring through artificial intelligence and this time telemetry.
In 2025, a white paper published by an international energy consortium laid out a strategy for reducing both cost and complexity in subsea data acquisition. It emphasized the use of AI assisted sensors capable of decision making at the seafloor, eliminating the need to constantly send data to surface operators. These sensors are now being paired with edge computing units submerged on the ocean floor, allowing for subsea telemetry without the latency issues seen in satellite based systems.
Another standout collaboration this year took place in the North Sea. Harvest and 3D at Depth partnered to create a digital twin of an existing subsea installation. This digital model not only allowed engineers to simulate repair scenarios but also facilitated predictive maintenance scheduling using machine learning. These kinds of developments show how digital twin North Sea applications are improving subsea asset integrity and reducing operational costs dramatically.
Toward Zero Carbon Subsea Technology News Energy Solutions
With global decarbonization goals becoming more urgent, the underwater energy world is under pressure to evolve. Fortunately, zero carbon subsea systems are no longer a distant dream.
SubCtech and Mocean Energy recently launched a fully autonomous power module that generates energy from ocean waves. The system includes wave energy converters, onboard batteries, and smart control logic to distribute power to underwater sensors and vehicles. Designed to operate for over a year without human intervention, this system is an important step toward building sustainable underwater infrastructure.
Meanwhile, Oceaneering and Kontiki Winds have inked a memorandum of understanding to electrify offshore assets using floating solar and wind platforms. Their plan is to connect renewable power directly to oil platforms, reducing diesel fuel consumption by up to 25% over the next two years. This bold move represents a practical step in merging renewable subsea energy with traditional oil and gas infrastructure.
Groundbreaking Hardware Subsea Technology News
Reliable subsea operations depend on rock solid hardware, and 2025 has seen some standout releases. One of the most anticipated launches is the BIRNS high amperage connector series. Engineered to deliver up to 1,000 amps, this compact connector system is ideal for powering subsea robotics and heavy-duty industrial equipment. It’s corrosion-resistant, high temperature rated, and compatible with modular subsea systems.
On the cooling side, R.W. Fern strum & Company celebrated 75 years in business by unveiling new compact cooling systems tailored for subsea applications. These systems are specifically designed for electronic housing in remote sensors and robotics. Their latest models use seawater driven heat exchange systems that are lightweight and energy-efficient.
Inspection technology also took a big leap forward. A new ultrasound system now provides remote, high resolution imaging with accuracy up to 0.1 millimeters. It enables non destructive testing in subsea environments where human divers cannot reach. The technology supports both scheduled maintenance and emergency repairs, often reducing inspection timelines by nearly 40%.
Legacy Players Continue to Innovate
Startups may be making headlines, but industry veterans aren’t standing still. On the contrary, they’re evolving fast leveraging decades of experience to drive cutting edge innovation beneath the surface.
For example, Ex pro, a trusted name in subsea engineering, just celebrated over 40 years of continuous operation. Throughout that time, they’ve carried out more than 250 subsea deployments, proving their staying power. Recently, they’ve taken a bold leap into the future by integrating AI driven underwater monitoring systems. These advanced tools use predictive analytics to detect corrosion and structural stress . Consequently, operators can respond faster and prevent costly damage before it happens.
Meanwhile, Kraken Robotics has also stepped up its game. To illustrate, their newest subsea laser scanner offers unmatched precision at depths of up to 120 meters. Because of this, pipeline inspections and seabed structure mapping are now more accurate and efficient than ever. In addition, Kraken introduced upgraded autonomous control systems, making their technology a leader in the fast growing field of automated subsea inspection.
All in all, these developments prove one thing: legacy companies aren’t just setting the pace. By combining deep expertise with new technology, they’re creating solutions that are both practical and visionary.
Innovation Hubs and Global Knowledge Exchange
Subsea breakthroughs don’t happen in isolation. This year, the Netherlands opened a state of the art subsea co innovation center. Equipped with high pressure testing tanks, simulation labs, and AI research facilities, the center is already hosting collaborative projects involving Delft University and major industry sponsors like TNO and Prysmian. Its goal is to shorten the time from research to world deployment.
At UTC 2023, the global community gathered to discuss the future of subsea technology. Topics ranged from offshore decarbonization strategies to hybrid power systems and subsea cybersecurity. Keynotes from executives at Siemens and ExxonMobil emphasized the need for greater data interoperability and automation. The conference closed with a firm message: global energy needs depend on smart, resilient subsea systems.
