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.

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.

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.
