- Offshore inspections remain expensive due to heavy reliance on ships
- Autonomous robots aim to remove humans entirely from offshore operations
- Sustained deployment replaces short missions with continuous data collection
Offshore operations have long relied on vessels and crews costing up to $100,000 a day, which is not only expensive but also dangerous and difficult to scale.
Bubble Robotics, a startup founded by former NASA and ETH Zurich roboticists, now claims to have a better solution.
The company emerged from stealth in April 2026 with $5 million in pre-seed funding and a plan to replace the expensive ships with autonomous robots.

Persistent bots instead of episodic vessels
Bubble Robotics’ core argument is straightforward: Offshore operations shouldn’t require people at sea, and instead of sending ships out on short missions, it deploys robotic systems that stay on site for months at a time.
These AI-infused machines inspect, monitor and collect data continuously without human intervention.
“Today, 80 to 90% of offshore inspection costs come from vessels and crews,” said Jean Crosetti, CEO and co-founder of Bubble Robotics.
“By removing this dependency, we unlock an incremental change in cost, security and frequency of operation. What used to be episodic becomes continuous.”
The timing of this approach aligns with a serious industry problem. The energy sector alone needs an additional 600,000 professionals by 2030, but the existing workforce is already stretched thin.
Bubble’s robots operate under a robotics-as-a-service model, meaning industrial customers pay for capacity without upfront capital expenditure or offshore mobilization.
This model reduces costs, alleviates labor shortages and increases inspection frequency.
In addition to industrial applications, maritime security remains an ongoing concern as submarine cables, ports and energy assets are largely unmonitored in real time despite increasing exposure to threats.
Persistent autonomous systems offer a way to detect anomalies and secure infrastructure without deploying human crews.
This technology relies on advances in edge AI and satellite connectivity that have reportedly reached a tipping point.
Whether these systems can really operate for months in harsh sea conditions without failure is still an open question.
Despite this concern, over $4 million worth of letters of intent have been signed, implying interest from the market.
But actual deployments will reveal whether the bots work as advertised.
The ocean is at the center of energy transition, global trade and climate resilience – yet history is littered with ambitious marine technologies that battled salt water, storms and biofouling.
Bubble Robotics may have a compelling thesis, but sustained autonomy at sea is a claim that requires proof, not just press releases.
