Sonardyne

Sonardyne makes underwater technology for positioning, navigation, communication, monitoring, mooring and release operations, and related data gathering. The company spans sales, contracting, finance, design, manufacturing, testing, distribution, installation and support, so its business is not limited to product manufacture but takes in delivery and after-sales assistance across the full lifecycle of subsea systems. Its offerings serve customers working in energy, ocean science, defence, and carbon capture and storage, covering offshore renewable wind energy, oil and gas life-of-field operations, maritime security, research, conservation, and subsea survey work. A central part of the business is underwater positioning and navigation. Sonardyne's systems support diver, ROV, AUV, towfish, USV and vessel operations, including dynamic positioning reference, seabed surveys, subsea inspections, deep-water node recovery, and autonomous or remote operations. The company builds acoustic communications systems for seabed-to-surface data transfer, monitoring products for environmental and subsea asset observation, and mooring and release systems for secure deployment and recovery of equipment. It offers marine robotics-related capability too, including support for uncrewed surface vehicles and command-and-control use cases. Integrated underwater sensing and acoustics run through the range. Its products combine software, topside equipment, in-water transponders, inertial navigation, Doppler velocity log sensing, pressure sensing, and acoustic data communications to improve tracking accuracy, reliability, and operational flexibility. Sonardyne supports custom engineering, adapting technology to specific customer requirements, and provides services such as field service, remote support, training, equipment servicing and repair, hydrostatic pressure testing, dynamic laser scanning, survey vessel charter and trials support, and USV data harvesting. Distinctive features include the company's broad system integration across hardware, software and support, its ability to serve both crewed and uncrewed operations, and its long-standing focus on underwater technology. Sustainability forms part of the picture: the company achieved carbon neutrality across its UK facilities ahead of schedule and continues work with its supply chain on carbon neutrality efforts.
