From discovery to decommissioning, we’re your life-of-field subsea technology provider
Our company is at work in almost every oilfield, supporting almost every phase of its development – safer, cleaner and more efficiently than ever before.
Exploration
We’re able to help reduce the cost of seismic data acquisition with solutions designed to simultaneously position thousands of cabled hydrophones, or track, command, and communicate with swarms of flying seabed nodes.
Survey and inspection
Our acoustic-inertial technology portfolio offers simplified solutions for site surveys and inspections utilising remote and autonomous vehicles, conventional vessels and uncrewed surface vessels – solutions that are helping to re-write the survey rulebook.
Construction
Managing risk, reducing complexity, reducing time offshore. Our trusted techniques and systems support your goals for installing and commissioning subsea structures in any water depth, with less equipment, in less time and with less people.
Asset integrity
Our expertise encompasses autonomous networks of seabed sensors monitoring structural vibration and safety critical control systems mounted on BOPs, to the detection, classification and localisation of hydrocarbon leaks, mooring line and riser monitoring. It’s also the ideal solution for monitoring your offshore CCS ensuring carbon remains captured.
Surveillance
Permanent seafloor surveillance, unpinned by our award-winning technology, unlock new insight into offshore reservoirs by identifying ways to optimise production, de-risk well placement and detect early signs of geo-hazards.
Vessel systems, including uncrewed
We’re able to extend the operational capability of your vessel, reduce downtime and enable your team to remotely support offshore operations from onshore. And with solutions for uncrewed vessels, we can deliver your data faster, safer and more sustainably than ever before.
Navigate, track, measure, monitor, release, observe. Your applications, our innovations
Sustainable, safe, efficient
Carbon neutral by 2025
We’re aiming to become carbon neutral by the end of 2025, an ambitious goal which covers direct and indirect emissions, including those associated with manufacturing as well as supply chain activities, from our UK sites and operations. It cements our long-term commitment to being an environmentally responsible and sustainable commercial partner to do business with.
Remote, over-the-horizon, uncrewed
Operating remotely and managing projects with less people at sea is more important than ever, so we’ve created new products and services to be by your side, event when we can’t be. Innovations such as ROAM which connects our experts to your team during live operations, and a fully managed data harvesting service using USVs.
Efficient, smart, quick
Our field-proven, low-risk technology is designed to let you achieve more with less hardware deployed on the seabed, efficiencies that save not just hours days but days of vessel time – and all without compromising the specifications set for your project.

Remote Advances; Operational Advantages
A joint operation between Sonardyne and Subsea 7 has helped to de-risk technology adoption on BP’s Mad Dog Phase 2 development by allowing 24-hour remote access to offshore survey systems for onshore staff, de-risking the use of new technology, reducing project overheads, and paving the way for new ways of working in the future.

Long ROV excursions, high elevation tracking, noisy waters – not a problem
ROV pipeline inspections in shallow water – with long excursions and high elevation tracking requirements – can pose major challenges for even the best USBL systems. With SPRINT-Nav in the mix, it’s no longer an issue. Tavis Letherby, Survey/ROV Manager at CCC (Underwater Engineering), explains.

Deepwater data analytics – asset monitoring at the edge
Thousands of kilometres of pipeline, flowline, and interconnecting spool pieces are installed on the world’s sea and ocean floors. Monitoring and maintaining these vast networks of pipes can be challenging. Explore how Oceaneering provided the analytics they needed to monitor these pipes using our SMART technology.

Seismic operations in the transition zone
We’re doing so much more using uncrewed surface vessel (USV) systems, right through the life cycle of exploration and production operations. It starts with the support of seismic data acquisition, using our Transition Zone Transceiver (TZ Transceiver).

Rewriting the subsea survey rules
Fusion 2 is not just simplifying offshore survey operations, it’s changing how people operate – for the better. Mike Clark, Global Survey Manager, i-Tech 7, told Baseline about their route to demonstrating reductions in offshore vessel schedules for Subsea 7’s deepwater field development projects using the real-time SLAM capability in Fusion 2.

Trendsetter Vulcan Offshore uses a SMART solution to monitoring wellhead fatigue
A reduction in subsea wellhead fatigue life was prevented through the use of a BOP Wellhead Fatigue Mitigation System supported by our Subsea Monitoring, Analysis and Reporting Technology (SMART). By enabling drilling operations using larger BOPs on older wellheads, operators are able to extend production and field life cost-effectively.

How to optimise carbon storage monitoring with marine robotics
Climate change is driving a ramping up of carbon capture and storage (CCS) projects globally, as countries work to reduce their emissions. There’s also more focus on how to make sure the stuff stays stored in the ground. Read on to hear about our involvement.

Using a hammer to crack a nut? Try using a USV instead
USVs are no longer a niche tool used within defence, they’re now regularly patrolling our oceans, gathering hydrographic and oceanographic data. Is it time that they were also used to support smarter, cleaner and more cost-effective offshore construction operations? Ed Moller, Head of Energy, thinks so.
