Subsea Warfare Need Not Involve Target Destruction

1 week ago | marinetechnologynews.com | Wendy Laursen

Countries bordering the Baltic Sea are on high alert after a number of outages of power cables, telecom links and gas pipelines since Russia's invasion of Ukraine in 2022, including sabotage of the Nord Stream gas pipelines. As defense analyst David R.
Cables and Connectors

Cable and connector manufacturers are rushing to meet the growing demand for subsea cables and connectors as renewables upscale, but whether it's renewables or oil and gas, there's also growing demand for high-tech subsea communications. The export cables that bring offshore wind power to shore are already so massive that one meter of cable can weigh 300kg.

The export cables that bring offshore wind power to shore are already so massive that one meter of cable can weigh 300kg. Nexans had previously upscaled its production facilities to cater for increasing demand; now it is upscaling its HVDC cables, typically 400kV, to 525kV. The company will be supplying at least 10 of these cable systems to European grid operator TenneT for multiple 2GW projects.
An Unintentional Iron Fertilization Experiment

3 weeks ago | marinetechnologynews.com | Wendy Laursen

The idea of fertilizing the ocean with iron, an element essential for the growth of phytoplankton, is being considered as a climate change mitigation measure - when they die, phytoplankton take carbon into the deep ocean. However, concerns have been raised about large scale intentional iron fertilization that may limit its effectiveness as a carbon dioxide removal strategy.
Inside the NOC Robotics Center

Much innovation in subsea robotics starts in academia, and the National Oceanography Centre in Southampton, UK, is a global leader with a fleet of more than 40 systems and 60 engineers and scientists. Alex Phillips, is the Head of Marine Autonomous Robotic Systems (MARS) at NOC, and Marine Technology recently caught up with him in his workshop to discuss key drivers in the evolution of efficient, effective underwater autonomous systems.

In a world increasingly shaped by climate uncertainty and geopolitical volatility, understanding the ocean - Earth's largest and least explored environment - is no longer a scientific luxury; it's a global imperative.
The Soundscape Code

1 month ago | marinetechnologynews.com | Wendy Laursen

Damselfish can make pops, clicks and chirps by grinding their teeth. When seeking a mate, some can make more high-pitched sounds. Another coral reef dweller, the snapping shrimp, makes a sound with its large claw to stun its prey or deter predators. A cavitation bubble is formed when the claw opens and closes rapidly, and the sound is produced when the bubble collapses. It's sounds like these that can be used as a proxy measure for reef health.
Artificial Reef or Ecological Trap

There's not a lot of data on the underwater ecosystems developing on and under floating wind structures; there's just not that many of these farms installed yet. A recent study by researchers in Scottish set out to analyze what data there is and to hypothesize about what the potential positive and negative effects might be for marine life. It's potentially important because floating offshore wind is being developed on highly productive shelf seas.
Fugro's Blue Eclipse┬" USV Makes Commercial Debut

1 month ago | marinetechnologynews.com | Wendy Laursen

This week, Fugro announced the first commercial contract for its Blue Eclipse® uncrewed surface vessel (USV). For the first time in its history, Norway's MAREANO will use USV technology to acquire seabed mapping data for the Norwegian Hydrographic Service. The Blue Eclipse®, the largest USV in Fugro's fleet, will survey over 675 square kilometers in the North Sea, with water depths ranging from 90 to 250 meters.
