- Offshore inspections remain expensive due to heavy reliance on vessels
- Autonomous robots aim to remove humans entirely from offshore operations
- Persistent deployment replaces short missions with continuous data collection
Offshore operations have long depended on vessels and crews that cost up to $100,000 per day, which is not only expensive but also dangerous and difficult to scale.
Bubble Robotics, a startup founded by former NASA and ETH Zürich robotics engineers, 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 those costly ships with autonomous robots.

Bubble Robotics' core argument is straightforward: offshore operations should not require humans at sea, and rather than sending out ships for short missions, it deploys robotic systems that remain 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 that dependency, we unlock a step change in cost, safety, and operational frequency. 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, yet the existing workforce is already stretched thin.
Bubble’s robots operate under a robotics-as-a-service model, which means industrial customers pay for capability without upfront capital expenses or offshore mobilization.
This model reduces costs, addresses workforce shortages, and increases inspection frequency.
Beyond industrial applications, maritime security remains a persistent concern, as subsea cables, ports, and energy assets are largely unmonitored in real time despite growing 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 allegedly reached an inflection point.
Whether these systems can truly operate for months in harsh ocean conditions without failure remains an open question.
Despite this concern, there are signed letters of intent worth over $4 million, which implies interest from the market.
However, actual deployments will reveal whether the robots perform as advertised.
The ocean sits at the center of energy transition, global trade, and climate resilience — yet history is littered with ambitious marine technologies that struggled against saltwater, storms, and biological fouling.
Bubble Robotics may have a compelling thesis, but persistent autonomy at sea is a claim that demands proof, not just press releases.
