Resident AUVs and Vessel Demand: What Could Change in the Gulf of America by 2031
Robots that live on the seabed have moved from demonstrations to multi-year contracts. But nearly all of that record comes from one region. This page separates what has been logged in the field from vendor forecasts, then asks what it could mean for vessel work in the Gulf.
Do not expect the Gulf’s vessel count to fall because of resident robots by 2031. GlobalData counts only three to six systems worldwide in or recently out of sustained commercial residency, almost all on the Norwegian shelf, and does not expect them to be routine on other major offshore fields until at least the mid-2030s[1]. We found no published resident deployment in the Gulf. Any early effect is more likely to appear as fewer vessel days per inspection on large, dense fields than as fewer vessels[1].
01. What has actually been logged
The useful numbers come from a small group of systems. Offshore Technology’s November 2026 review, which draws on GlobalData and the operators, gives the clearest current picture[1].
| System | Type | Field record | Where |
|---|---|---|---|
| Saipem Hydrone-R[1] | All-electric resident intervention drone | 500+ days of residency; record 240 straight days on the seabed; 280+ docking missions over two deployments | Njord, under a 10-year Equinor contract worth about €40m |
| Oceaneering Liberty[1] | Cage-and-buoy resident ROV, not a docked AUV | Nearly 21,000 operational hours | Åsgard, Snorre, Statfjord, Gullfaks |
| Liberty E-ROV campaign[2] | Battery ROV flown from shore in Stavanger | 56 days on the seabed; 1,344 subsea hours; recovered with 16% battery | Åsgard B, about 300 m |
| Modus / PXGEO Sabertooth[1] | Resident drone | First resident-drone contract, 2023–2024 | Johan Sverdrup |
| Saipem FlatFish[1] | Autonomous inspection vehicle | Passed functional acceptance tests for Petrobras, March 2026 | Approved for ultra-deep water, Brazil |
Figures as reported by the operators and contractors; none has been independently audited.
Hydrone-R’s best argument is weather. It supported well commissioning in wave heights up to 12.5 m, when conventional work-class ROV operations were impossible, and Njord lost no operating days to weather while the site’s conventional ROV was suspended. Remote operation has saved more than 36,800 offshore personnel-hours[1].
02. What still needs a vessel
- •Launch and recovery. A vessel is still needed every six to eight months[1]. The Liberty E-ROV also used one for deployment and recovery[2].
- •Fallback. Public data on recovering a failed AUV is scarce, and a vessel with an ROV remains the backup for a damaged vehicle[1].
- •Heavy work. Valve operation and manipulation are still done mostly by ROVs. Construction, installation and repair vessels face little near-term risk[1].
- •Reach and charging. Autonomous inspection can cover up to 12 km from the dock, but piloted intervention is typically limited to 300–400 m, and charging takes 8 to 32 hours between missions[1].
- •Slipped targets. Eelume’s 2021 goal of up to 50 robots by 2027 has not been met, and Equinor, which bought an Eelume S in September 2025, still calls its use experimental[1].
03. Two forecasts, very different
SoftServe said in November 2026 that 90% of subsea inspections are expected to run in remote or autonomous modes by 2035, in a post promoting its Unified Subsea Digital Twin Suite[3]. The suite combines digital twins, 3D visualization, AI analytics and robotic mission control[4]. We found no independent forecast behind that number, and the post does not define what counts as “remote.” A standard ROV flown from an onshore control room would qualify, even with a vessel overhead.
GlobalData is more cautious: resident systems should be a normal part of the inspection mix on large Norwegian fields by 2030, but not routine elsewhere until at least the mid-2030s[1]. Both can be partly right, because remote piloting can spread much faster than seabed residency. For vessel planning, the difference matters: remote control changes where the pilot sits, while residency changes whether a boat has to come at all.
04. Where the Gulf stands today
We found no published commercial resident deployment in the Gulf of America, and the main reviews do not mention the region[1]. Some of the design thinking has Gulf roots: Oceaneering unveiled its Freedom vehicle at OTC in Houston in 2019[5], and our earlier guide covers seabed garages, telemetry and BSEE rules.
Current ROV demand here is being driven by something else. Oceaneering’s third-quarter 2026 results show fleet utilization steady at 65% and revenue per ROV day up to $11,781, with lower U.S. Gulf activity offset by Europe, Guyana and West Africa. The company expects utilization to fall in the fourth quarter as certain rigs leave the U.S. Gulf for other regions[6][7]. Resident robots have no part in that movement.
05. Which vessel work is exposed, and when
| Work | Exposure by 2031 | Why |
|---|---|---|
| Routine annual inspection on large, dense fields | Moderate, if a Gulf pilot starts soon | The first work GlobalData sees at risk on the Norwegian shelf[1] |
| ROV support and light IMR | Low to moderate | Exposed, but valve work and manipulation still favor ROVs[1] |
| Drilling and completion ROV support | Low | Tied to rig activity; a resident system does not replace it (our assessment) |
| Construction, installation and heavy repair | Very low | Little near-term risk[1] |
| Launch, recovery and rescue of resident systems | New, small demand | Vessels return every six to eight months and act as the fallback[1] |
Exposure ratings are our judgment based on the cited evidence. They are not market forecasts, and no published Gulf vessel-day figures exist.
- •Operators: ask for vessel days per inspection, not just robot hours, and ask who pays for recovery if a vehicle fails.
- •Vessel owners: routine inspection days are the ones to watch; heavy-work days are not under pressure yet.
- •Equipment buyers: check dock compatibility early. A GlobalData analyst says API 17F docking stations with Subsea Wireless Group inductive couplers let Saipem, Saab Seaeye and Oceaneering vehicles use the same station[1]. We have not reviewed the standard’s clauses, so confirm this with vendors.
- •Crews: expect more shore-based piloting. Liberty’s Åsgard B campaign needed no dedicated offshore personnel during operations[2].
06. Frequently Asked Questions
Are resident AUVs working in the Gulf of America? ↓
We found no published commercial resident deployment in the Gulf as of November 2026. GlobalData says sustained commercial residency involves only three to six systems worldwide, almost all on the Norwegian Continental Shelf.
Will resident robots eliminate subsea support vessels? ↓
No. A vessel is still needed for launch and recovery every six to eight months, and a vessel with an ROV remains the fallback for a damaged vehicle. Heavy construction and repair vessels face little near-term risk.
Is it true that 90% of subsea inspections will be remote or autonomous by 2035? ↓
That is a SoftServe forecast, made in a post promoting its digital twin product. We found no independent source for it. GlobalData does not expect resident systems to be routine outside large Norwegian fields until at least the mid-2030s.
How long has Hydrone-R stayed underwater? ↓
It has logged more than 500 days of residency, including a record 240 consecutive days on the seabed, and more than 280 docking missions across two deployments.
Is Oceaneering Liberty a resident AUV? ↓
No. It is a cage-and-buoy resident ROV with nearly 21,000 operational hours on the Norwegian shelf. One battery-powered Liberty E-ROV campaign at Asgard B logged 1,344 subsea hours flown from shore.
