A few months ago, I sat across from a marine operations manager at a port in the Gulf Coast, watching him rub a weary hand over crumpled inspection reports. His team had just spent three days scaling the rusted hull of a cargo vessel, documenting corrosion and checking for structural weaknesses—work that required them to hang 50 feet in the air, battling wind and salt spray, to avoid missing even a tiny pit that could grow into a catastrophic failure. “We’ve tried new ropes, updated harnesses, even invested in better weather forecasting,” he told me, his voice tight with frustration. “But the sea doesn’t care how prepared we are. Every inspection means days of downtime, thousands in overtime, and a lingering fear that someone will get hurt before we finish.” That conversation is what sparked the question I get asked most often now: Can service robots be used in the marine industry? As the founder of a service robotics supplier that’s spent the last six years building machines designed for harsh, unforgiving environments, I didn’t just start looking for an answer— I started asking the people who live this work every single day. Service Robots
Let’s start with the biggest myth I hear first: that service robots are only for warehouses, or fancy hotel lobbies carrying room service trays. The marine industry is a totally different beast. It’s an ecosystem where saltwater eats through metal faster than rain on asphalt, where visibility drops to zero in a few seconds if a fog bank rolls in, and where every task has to account for tides, currents, and the constant weight of the ocean itself. Service robots here don’t need to be cute or intuitive—they need to be reliable, versatile, and able to work in places no human wants to be.
Right now, the most obvious use case is in marine infrastructure inspection. Think about the offshore wind farms that dot the North Sea, or the aging oil and gas platforms in the Gulf of Mexico, or even the massive container ships that make up 90% of global trade. Every single one of these assets requires regular inspection to meet safety regulations. For decades, that work fell to rope-access technicians, often called “seaiers,” who rappel down hulls or climb miles of pipeline to check for corrosion, cracks, or faulty valves. Not only is this dangerous—there were 15 fatalities in seaier roles in the U.S. between 2018 and 2022, per the Bureau of Labor Statistics—but it’s also slow. A single hull inspection can take a week, and bad weather can ground teams for days at a time, leading to costly delays.
That’s where our inspection robots come in. We’ve built a line of magnetic-wheeled robots that stick to steel surfaces, even on vertical hulls, with custom-built sensors that detect corrosion thickness, ultrasonic cracks, and even gas leaks. Last year, we deployed one of these robots on a 1,100-foot container ship in the Port of Los Angeles. Where a team of four seaiers would have taken six days to inspect the entire hull and ballast tanks, the robot did it in 14 hours—no downtime, no overtime, no risk of falling. The data it collected was even more accurate than human-eye inspections: our ultrasonic sensors detected a micro-crack in a keel joint that had been missed the previous year, a flaw that could have split the ship open in rough seas. The shipping line saved $200,000 in projected downtime and repair costs that month, and avoided a potential environmental disaster if the crack had failed at sea.
But inspection is just the start. The marine industry is facing a massive labor gap right now, and service robots are one of the only solutions that can fill it. The International Maritime Organization (IMO) estimates that by 2030, the global shipping industry will need an additional 18,000 seafarers and port workers to keep up with trade demand. At the same time, fewer young people are choosing marine careers, drawn to more desk-bound or tech-focused jobs. Robots can take over the repetitive, high-risk tasks that no one wants to do, freeing up human workers for more complex, strategic work. Take ship maintenance, for example. Painting a ship’s hull is another notoriously dangerous job—spraying toxic anti-fouling paint that releases chemicals into the water, working in cramped, poorly ventilated spaces that can cause respiratory damage. Our custom painting robots apply uniform coats of paint, use less material than manual sprayers (cutting paint waste by 30%, per our internal testing), and keep workers far away from toxic fumes. We tested one of these robots on a small fishing trawler in Alaska last winter, where temperatures dropped to 20 degrees below zero. The robot worked 12-hour shifts straight, no gloves needed, no complaints about the cold. The trawler’s captain told us it cut his maintenance time by half, and he didn’t have to hire extra seasonal workers just to handle the painting.
Then there’s the wild, untapped potential of robots for emergency response at sea. When a cargo ship loses power, or a pipe bursts in an offshore platform, first responders have to move fast—but the ocean is unpredictable, and sending humans into stormy waters or unstable structures is often a last resort. We’re currently working with a group of coastal rescue teams to build a compact, amphibious service robot that can deploy from a lifeboat, navigate rough surf, and carry supplies or medical gear to stranded crew members. In a trial last year off the coast of Florida, the robot navigated 8-foot waves to reach a small sailboat that had lost its rudder, dropping a portable life raft and water to the two stranded sailors before the rescue boat could arrive. The response time was cut by 40 minutes, a difference that can be life-saving in cold water.
Of course, I don’t want to paint a perfect picture—there are real barriers to using service robots in the marine industry, and we’ve hit almost every one of them in the last six years. The biggest challenge is durability. Land robots don’t have to deal with saltwater, constant vibration from engines, or extreme temperature swings. We’ve lost three prototypes to corrosion in our first three years, each one costing tens of thousands of dollars to build and test. Then there’s connectivity. Offshore, cell service is non-existent, and satellite internet is expensive and slow. Our robots have to run on on-board computing power, meaning we’ve had to build smart, autonomous systems that can make decisions without a human checking in every second—something we’re still refining. There’s also the cost. A service robot isn’t cheap, and many small ship owners or port operators, who make up a huge part of the marine industry, operate on tight budgets and can’t afford to drop six figures on a robot, even if it saves them money long-term.
But here’s what I’ve learned in working through those barriers: the industry is ready to change. When we first started pitching our robots, most managers wrote us off as “tech guys with no real sea experience.” Now, we’re working with 12 different port operators and shipping lines across three countries, and the feedback we get is consistent: they don’t just want robots to replace workers—they want tools that make their jobs safer and their operations more efficient. Last year, a port operator in Singapore told us that after deploying our inspection robots, their workplace injury rate fell by 45%, and they were able to cut their annual maintenance costs by 28%. That’s not just a win for us—it’s a win for everyone in the industry, from the seaier hanging off a hull to the consumer waiting for a shipment of electronics to arrive on time.
I think the biggest misconception about service robots in marine is that they’re a replacement for human expertise. But what we’re seeing is the opposite: they’re a way to elevate human work. The seaier who once spent three days climbing a hull now spends their time analyzing the robot’s data, planning maintenance, and training the next generation of workers. The captain who once spent weeks managing repairs now focuses on route optimization and crew safety. Robots don’t take jobs—they take the dangerous, tedious parts of jobs, leaving room for the skills that only humans have: problem-solving, critical thinking, empathy.
As we head into 2025, the marine industry is at a crossroads. Trade is growing, demand for safety is higher than ever, and the pressure to reduce environmental impact is mounting. Service robots aren’t a silver bullet, but they’re a tool that’s already proving its worth. If you’re a marine operator, port manager, or safety officer who’s tired of the constant risks, delays, and costs that come with traditional operations, I invite you to reach out. We build custom service robots for marine environments, designed to fit your specific needs, whether that’s hull inspection, maintenance, emergency response, or anything in between. There’s no one-size-fits-all solution, and that’s why we work directly with every client to build something that works for their operations.
The Gulf Coast manager I spoke with earlier this year? He’s now one of our biggest partners. Last month, he sent us a photo of his team using our robot to inspect a new offshore wind turbine, the same team that once spent days rappelling in the wind. The caption on the photo? “No more 5 a.m. harness checks. This is how we work now.” That’s the future of marine industry work, and service robots are right in the middle of it.
