Overview
From discovery to decommissioning, we’re your life-of-field subsea technology provider
We provide you with comprehensive support across every phase of oilfield development, delivering innovative solutions to enhance safety, efficiency, and environmental sustainability. From exploration to asset management, we provide cutting-edge technologies to optimise offshore operations, including advanced seismic data acquisition, autonomous survey techniques, and sophisticated seafloor monitoring systems.
Our technological portfolio spans critical maritime operational domains, including but not limited to, underwater construction, asset integrity and permanent seafloor surveillance. We offer transformative solutions that reduce operational complexity, minimise offshore personnel requirements and enable remote monitoring through autonomous sensor networks, uncrewed vessels and advanced acoustic-inertial technologies. These innovations not only improve operational efficiency but also support critical objectives like carbon capture and production optimisation.

Subsea structure installation
When everything rests on landing a structure to within a few mm, why risk using anything other than the trusted industry standard?
What our tech can do for you:
• 15 mm – achievable ranging accuracy
• Scalable – to suit any project; large or small
• 6000 m – working depth
• Efficiency – highly repeatable positioning saves fuel and emissions
Wellbore monitoring
Being able to access wellbore data during well testing, production or suspension, means you can proactively manage your risks and keep production flowing.
Our downhole data loggers and modems interface with industry standard gauges and can remain deployed for years without intervention.
What our tech can do for you
• IWIS – compatible with Intelligent Well Interface Standardisation
• 5 years – typical life on a single battery between servicing
• Remote – remote data acquisition with USVs / AUVs for safer, greener operations
• Gauges – work with all industry standard downhole gauges
Autonomous underwater vehicles
Autonomous Underwater Vehicles (AUVs) are becoming more useful, reliable, and capable. However, one size doesn’t fit all, so that’s why our subsea technologies have been designed to be compatible with AUVs of all sizes and capabilities, from micro to hybrid to resident.
What our tech can do for you
• 9,000 bps – fast and robust acoustic communications performance
• OEM – INS, DVLs and USBLs for any AUV or USV platform
• Swarms – surface-to-AUV and AUV-to-AUV comms supported
• 11 km – Reliably track and communicate to the deepest parts of the ocean
Acoustic BOP control
We keep you in control of your drilling operations with a high security, through water wireless acoustic communications link. This enables you to execute emergency shutdown and disconnect in the event of loss of primary communications with a blowout prevention (BOP) stack.
What our tech can do for you
• 4,000 m – reliable and robust operations even in deep water
• Redundancy – high security, acoustic communications link
• Compatibility – works with any blow out prevention set up
• 12 – up to 12 function outputs operate the solenoid valves
Pipeline positioning
Specifying Sonardyne hybrid acoustic inertial technologies to support your pipeline installation offers the lowest risk solution encompassing the best performing technology, free consultative help and a 24/7 global support network directly contributing to the success of your project.
What our tech can do for you
• Inventory – achieve more with less equipment on the seabed
• QC – install, touchdown and inspect your pipelines with absolute confidence
• 15 mm – accuracy achieved with our LBL subsea transponders
• USV – support your move to safer, green, cheaper construction operations
Riser monitoring
Understanding subsea drilling and production riser position and movement is key to ensuring your rigs or ships keep within a position tolerance and maintain integrity. Our secure acoustics provides a wireless alternative expensive cabled sensors which are vulnerable to damage.
What our tech can do for you
• 9,000 bps – fast and robust acoustic communications performance
• DP – integrate with your vessel’s DP system for position correction
• 5,000 m – hardware configurable up to 5,000 m depth rating
• 24-hour – support, whenever and wherever you are in the world
Seabed deformation monitoring
Developed over more than a decade and in use globally by the energy sector, our ‘game-changing’ seabed deformation monitoring technologies offer you critical new understanding of seafloor movement and its impact on your reservoirs and installed structures.
What our tech can do for you
• 10 Years – long-term unattended deployment and monitoring of the seabed
• USV or AUV – remote data acquisition for safer, greener survey operations
• 9,000 bps – fast and robust communications performance
• 6000 m – working depth, perfect for deep water operations
Uncrewed surface vehicles
USVs are the safe, green and economical way to harvest ocean data, which is why energy, defence and science users like you are increasingly moving to uncrewed operations. We can equip any of your uncrewed platforms to track, communicate and command in the underwater domain.
What our tech can do for you
• 99 – up to 99, simultaneously tracked targets below the water
• 9,000 bps – high speed comms for vehicle control and data harvesting
• Uncrewed – support real-time, over horizon operations
• 230 m – achievable bottom lock for shallow water navigation
Deep water nodal positioning
Your deep water ocean bottom nodal surveys need to be conducted efficiently and with precision. Our vessel-based USBL and cable-mounted SST technologies answer this requirement with hardware that can be moved between your vessels and withstand automated deployment and recovery.
What our tech can do for you
• 1520 – hundreds of unique transponder identities for high density coverage
• Rugged – hardware built to withstand automated deployment and recovery
• 1 Hz – positioning update rate regardless of water depth
• 3000 m – working depth, perfect for seismic nodes operations
Dynamic positioning reference
We’ve been engineering high integrity position reference systems for dynamically positioned vessels since the early 1990s. Giving you added reliability and operational savings, our solutions blend acoustic, inertial and Doppler sensors and are fully compatible with all makes DP system on the market.
What our tech can do for you
• Class 2 & 3 – add redundancy to your operations for IMO regulations
• Efficiency – highly repeatable positioning helps save fuel and emissions
• Crewed or Uncrewed – our technology is suitable for all vessels, including USVs
• Compatibility – integrates with your existing DP system
