GeoAcoustics Expands Sonar Cable Molding and Assembly Services
its Great Yarmouth headquarters. This move unlocks increased capacity and specialist expertise, enabling the delivery of complex, high-reliability cable moldings and terminations for a wide range of marine and subsea applications.Cable molding is a critical process in the production and use of underwater equipment, involving the sealing and encapsulation of cable terminations to ensure electrical integrity, water ingress protection, and mechanical durability under harsh ocean conditions. High-quality moldings are essential for maintaining signal fidelity, power continuity, and long-term system reliability
MacArtney Introduces 9-Contact SubConn Connector
connector. With enhanced features designed to minimize signal interference, the connector ensures optimal data accuracy and efficient underwater operations.With enhanced shielding, the 9-contact connector minimizes electromagnetic interference, providing a stable and uninterrupted connection for underwater equipment.It features optimal data integrity, minimal signal loss, and high data fidelity - critical attributes for advanced underwater applications."Maintaining signal integrity is crucial in the often harsh subsea and marine environments, and the new connector is designed to meet this challenge
How Do You Build Tunnels and Bridges Underwater?
any gap and must continuously be pumped away.Human beings, materials and machinery don’t really work well underwater, either. People need a constant air supply. Placing concrete is difficult underwater, and some materials work only on dry land. And since gas engines rely on air to operate, underwater equipment is very limited.Some smaller tasks – aligning and joining pre-built sections of tunnel or inspecting to make sure submersion didn’t damage anything – are performed beneath the waves, but the bulk of construction is unlikely to be. Once the structure is in place, there&rsquo
LUMA X-UV Passes 1200 Bar Pressure Test, Hydromea says
depths of Earth's oceans. By doing so, we provide research teams and the offshore energy industry with new means to communicate with sensors and collect data at lightning speed. The compact form factor of our LUMA X modems, comparable to a soda can, allows for effortless integration into any underwater equipment. We eagerly anticipate witnessing our Swiss-made LUMA modems helping the scientists to uncover secrets of Mariana Trench soon."
Kawasaki's AUV Used to Inspect Coating Defects on Subsea Pipeline
from the UK’s Modus Subsea Services Limited for the first commercial model of SPICE, which will be an upgraded version of the SPICE that was used for this verification test, and is currently working on production and tests for its commercialization."To meet growing market demand for underwater equipment such as AUVs, which can achieve more advanced unmanned automated operations, Kawasaki is committed to developing high performing high-quality products and accelerating its development efforts to expand commercial utilization of AUVs," Kawasaki said
Putting Power on the Seafloor is a Fuel Cell Future
. This could be to track environmental and climate trends or for exploration projects, where mobile, modular solutions would be beneficial. However, these are tending to be more power hungry, especially when energy-intensive robotic systems start to be added into the mix.At the moment, power for underwater equipment or sensors tends to come from either batteries or cables. Cables are prohibitively costly for projects at any distance from the coast and no appropriate for systems only in place for a few years, while batteries are expensive and wasteful.GEOMAR’s solution is a fuel cell, developed in
Saipem, WSense Developing Comms Networks for Subsea Drones
be designed and qualified by Saipem and WSense to be interfaced to underwater drones engineered and operated by Sonsub, Saipem's center of excellence for submarine technology innovation. According to Saipem, these nodes will represent a game-changer for the wireless interconnection of underwater equipment and sensors as well as the integration of diversified systems and technologies, with applications spanning over different industries, including offshore energy, infrastructures, and defense."Thanks to stations installed underwater, Saipem's resident subsea drones and ROV will be able
Sonardyne USBLs Installed on Brazilian Geoscience Vessels
operations across the region.Ranger 2 Ultra-Short Baseline (USBL) systems have been installed on board OceanPact’s research vessels Seward Johnson and Austral Abrolhos, both currently on hire to Brazilian oil major Petrobras. The systems will be used to precisely track the location of underwater equipment and sensor packages deployed from the ships, including seabed corers, towed sensors and data loggers. Both vessels are currently on hire to Brazilian oil major Petrobras. MarineTraffic shows the Austral Abrolhos is currently operating near the floating production, storage and offloading
Hydrex Earns Belgium, Netherlands Approvals
Belgium and the Netherlands, have banned the underwater cleaning on propeller blades. Exceptions are only made for those companies that can pass the very stringent tests carried out by the concerning authorities.Approved Approved propeller blade cleaning is carried out by Hydrex divers using underwater equipment developed in-house by the Hydrex R&D department. This process is fast and easy and has no effect on the underwater environment
