Sonardyne International Ltd, a world-leading provider of underwater positioning, navigation, and sensing solutions for maritime operations, has achieved remarkable successes in sustainable growth and global expansion. Their innovations serve offshore energy projects, defense operations, ocean science research projects, subsea interventions worldwide and more.
Enterprise 2025 won two Double King's Awards from Enterprise International.
On 6 May 2025, Sonardyne celebrated a rare double honor in the King’s Awards for Enterprise, recognized for both Sustainable Development and International Trade. This distinction places the company among only two UK organizations receiving dual awards that year, alongside 197 others.
Sonardyne has earned the Sustainable Development award to demonstrate their dedication to environmental responsibility. They set themselves an ambitious target of reaching carbon neutrality across UK facilities by the end of 2025 as per PAS 2060; independent verification confirmed they accomplished it two years early with initiatives such as installing 1,300 photovoltaic panels producing 533kW, implementing ISO 50001 energy management and upgrading infrastructure.
Graham Brown, Sonardyne's Managing Director, expressed his ecstatic appreciation of this award: We're absolutely delighted to receive such an acknowledgement, especially since two King's Awards in 2025 really underscore Sonardyne's success while working sustainably. HSE Manager Carl Holland noted how Sonardyne strives to build sustainable businesses which serve local communities while protecting the environment.
The International Trade Award honors an 83% increase in direct exports over three years across energy, defense and ocean science sectors. This expansion leverages teams in the UK, USA, Singapore and Brazil with plans to open new offices in Germany in 2025.
Carbon Neutrality and Future Sustainability Plans.
Sonardyne's commitment to sustainability extends far beyond UK operations. After attaining carbon neutrality ahead of schedule, Sonardyne continues supply chain assessments and energy optimizations in its supply chains and energy optimizations efforts. By 2025, they hope to incorporate emissions from international sites including Brazil, USA and Singapore and pursue ISO 14068 certification via LRQA.
Sonardyne Marine Technology was an early proponent of sustainable practices within marine technology, and demonstrated how such practices bring operational benefits such as reduced energy use and enhanced efficiency.
Strategic Contracts and Technological Advancements
Sonardyne secured a monitoring contract for Net Zero North Sea's (NEP), the UK's inaugural offshore carbon capture and storage (CCS) site, in June 2025. This contract provides baseline environmental monitoring services as part of decarbonization initiatives in support of decarbonization efforts.
Earlier, France’s STAPEM Group selected Sonardyne’s Ranger 2 Ultra-Short Baseline (USBL) system for the 2024-delivered vessel STAPEM Boreale. This supports ROV operations for inspection, survey, and intervention by Film-Ocean, complementing an SMD Atom work class ROV equipped with Sonardyne’s AHRS, Syrinx DVL, and Wideband Sub Mini 6+ transponder.
Product Innovations in Maritime Research and Robotics
Sonardyne integrated -4H-JENA's CONTROS HydroC CO2 sensor into their Origin 600 Acoustic Doppler Current Profiler (ADCP), providing real-time ocean acidification monitoring alongside current profiling for marine ecosystem research.
The company launched SPRINT-Nav U, the world’s smallest hybrid acoustic-inertial navigator at 135 mm tall, 114 mm diameter, and 600 grams in water. Targeted at small ROVs, AUVs, towfish, and USVs, it delivers survey-grade navigation.
Sonardyne leads a consortium developing an underwater single photon imaging system for 3D subsea mapping, partnering with Fraunhofer UK Research Ltd and RedWave Labs Ltd. Additionally, its Element project advances ADCP technology for offshore wind, measuring currents, temperature, and integrating LiDAR data via satellite.
Market Expansion and Leadership Transitions
Sonardyne recently appointed Aquatic Sensors as resellers to enhance US growth. Furthermore, Dr. Ralph Rayner joined as Non-Executive Chairman to bring expertise into its board of directors.
Sonardyne's advances establish it as an industry leader for sustainable maritime technology, driving efficiency in offshore operations globally.
