- Offshore inspections remain costly due to heavy reliance on ships
- Autonomous robots aim to completely eliminate humans from offshore operations
- Persistent deployment replaces short missions with continuous data collection
Offshore operations have long relied on vessels and crews that cost 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 robotics engineers from NASA and ETH Zürich, 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 these expensive ships with autonomous robots.

Persistent robots instead of episodic ships
Bubble Robotics’ main argument is simple: Offshore operations shouldn’t require humans at sea, and rather than sending ships on short missions, it deploys robotic systems that stay on site for months.
These AI-powered machines continuously inspect, monitor and collect data without human intervention.
“Today, 80 to 90 percent of offshore inspection costs come from vessels and crew,” said Jean Crosetti, CEO and co-founder of Bubble Robotics.
“By removing this dependency, we achieve a step change in cost, safety and operational frequency. What was once episodic becomes continuous.”
The timing of this approach corresponds to a serious industry problem. The energy sector alone will need 600,000 additional professionals by 2030, while the existing workforce is already limited.
Bubble’s robots operate on a robotics-as-a-service model, meaning industrial customers pay for capacity without upfront capital expenditure or offshore mobilization.
This model reduces costs, addresses labor shortages and increases the frequency of inspections.
Beyond industrial applications, maritime security remains a persistent concern as submarine cables, ports and energy assets go 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 builds on advances in advanced AI and satellite connectivity that have reportedly reached an inflection point.
Whether these systems can actually 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, indicating market interest.
However, actual deployments will reveal whether the bots work as advertised.
The ocean is at the center of the 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 persistent autonomy at sea is a claim that requires proof, not just press releases.
