Autonomous Inspection in Brazilian Offshore
Technology briefing from the MINERVA oil & gas vertical
Executive synthesis
MINERVA's first configured vertical tracks 22 oil & gas concepts across six evidence dimensions. Autonomous inspection is the concept where scientific, technological and industrial momentum align most clearly, while capital commitment lags. The briefing separates what is moving from how confident the evidence lets us be.

Petrobras clears Saipem's FlatFish autonomous inspection drone for ultra-deepwater field deployment
After factory acceptance tests in Trieste under a 2023 contract, Petrobras approved the final phase: implementation of a resident/semi-resident autonomous inspection drone in Brazilian ultra-deep water. It is a qualification step, not yet field operation; vessel-free inspection moves from R&D pilot toward operational use.

Brazilian E21B patent filings sit flat at one fifth of their 2013 peak, while subsea groups gain share
MINERVA over the full INPI base: E21B filings peaked at 2,117 in 2013 and have plateaued at 400–540 a year since. There is no rise above baseline. The movement is in composition: between 2009–13 and 2019–23, E21B 41 (subsea and other equipment) rose from 2.08% to 7.26% of filings (+5.18 pp). Filings from 2024 onward are incomplete under the 18-month secrecy period.

Petrobras budgets US$ 9.7 bn for decommissioning in its 2026–2030 plan
Petrobras earmarked US$ 9.7 bn over five years for sustainable disposal of equipment and well abandonment, under ANP Resolution 817/2020, which requires decommissioning programmes (PDIs) five years before offshore production ends. A large end-of-life pipeline raises the value of asset integrity histories; no tender yet names inspection data as an award criterion.

Autonomous subsea inspection literature grows about 3x in a decade while the offshore oil and gas corpus grows 31%
OpenAlex, 2016–2025: works on subsea/underwater inspection with AUV, ROV, resident or autonomous vehicles rose from 89 to 275 a year (CAGR 13.4%), against 2,641 to 3,451 (CAGR 3.0%) for offshore oil and gas. Their share of the offshore count went from 3.4% to 8.0%, with the jump in 2023–2025. Resident-vehicle work proper is still tiny (2 → 11 a year).
