Optimising shallow water positioning for combined magnetometer and hydrographic surveys

Pipeline and cable detection and depth of burial surveys are an essential part of any offshore renewable project. Ocean Floor Geophysics are working on ways to improve how these types of survey are done. Read how they worked with Covelya Group company EIVA to demonstrate their Hypermag gradiometer with an optimum Sonardyne shallow water positioning and navigation solution.

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.

Subsidence monitoring at offshore oilfields

Read if you’re interested in subsidence monitoring at offshore oilfields, and how our long endurance autonomous instruments and remote, working together with an uncrewed surface vessel, helped Norkse Shell measure seabed movement across the giant Ormen Lange gas field.

Over-the-horizon uncrewed ocean data collection

Seabed monitoring over large areas has entered the age of autonomy, thanks to a combination of our long-endurance, wireless Fetch seabed sensors and a wide choice of uncrewed surface vessels (USVs) able to harvest their data. Read how Shell is making use of both offshore Norway. 

Deepwater structure installation made easy

Read if you’re interested making subsea developments safer, cleaner and more efficient than ever before, and how our GyroCompatt helped China Offshore Fugro Geosolutions achieve its project goals

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.
