The most expensive part of a barnacle is the fuel it burns. For the global shipping fleet, the slow creep of algae and shellfish on a hull, biofouling, isn't just a maintenance headache. It's a physics problem, adding enough drag to burn an extra 10% to 40% of fuel [Sonihull, retrieved 2026]. TUCCO, a London startup, is betting there's a gentler, more continuous way. Its proposed solution is a fleet of autonomous underwater drones that glide around berthed ships, bathing their hulls in UV-C light to kill the biofilm before the barnacles ever get a foothold [Tucco LTD, retrieved 2024].
The UV-C Wedge
TUCCO's system is a bundle of deep-tech components aimed at a single, stubborn problem [Startupbootcamp, undated profile]. An autonomous underwater vehicle uses AI navigation to map and cover every square centimeter of a submerged hull. Onboard banks of UV-C LEDs then emit a precise dose of ultraviolet light, a wavelength known to disrupt microbial DNA. The target is the invisible, slimy biofilm of bacteria and algae that forms first. By zapping this foundational layer regularly, the theory goes that you prevent the heavy fouling from forming in the first place.
A Crowded Harbor
The market TUCCO is swimming into is both vast and fragmented. The cost of biofouling prevention and remediation is often cited in the ballpark of $100 billion annually for commercial shipping [Sonihull, retrieved 2026].

The Early-Stage Fog
What's clear from the public record is the ambition of the technical proposition. What's less clear is the path to proving it at commercial scale. The company was incorporated in late 2022 and has been active in the startup ecosystem [Tucco LTD, retrieved 2024]. A co-founder, Pietro Bonavita, is identified on LinkedIn. This is typical for a pre-seed deep-tech hardware venture but frames the current phase as one of technology development and validation. To win, TUCCO must prove its drones are not just clever, but cheaper and less disruptive than the shipyard.
