Greensea IQ recently conducted a rapid-response demonstration of its EverClean robotic hull-cleaning system for the U.S. Army at Joint Base Pearl Harbor–Hickam.
The event was initiated after Army leadership identified a critical requirement to reduce hull fouling and improve vessel performance while minimizing maintenance downtime. When a previously scheduled supplier withdrew, Greensea IQ mobilized technicians and equipment from across the country in under four days to fulfill the operational need. This rapid deployment showcased how mature, commercially proven autonomy can be applied to enhance the readiness of large and logistically complex vessel fleets.
Based in Richmond, Vermont, Greensea IQ specializes in advanced subsea robotics and autonomy for defense and commercial sectors. During the demonstration at the strategically significant maritime hub, which supports the U.S. Pacific Fleet, the company’s technology was evaluated by a multi-service group including Army vessel crews, Navy maintenance personnel, and dive units from both the Army and Navy.
The demonstration highlighted the efficiency of robotic solutions compared to traditional manual methods. It is estimated that a single operator using the robot can clean an Army Large Tug or Landing Craft Utility hull in approximately six hours. Implementing fast, in-water cleaning has a direct impact on reducing fuel consumption and increasing vessel range and maneuverability.
Col. Rachael Hoagland stated, “Greensea IQ demonstrated what private-sector agility truly looks like. Their team immediately mobilized—funding their own travel, shipping robots across the country, and arriving in Pearl Harbor ready to perform. Their responsiveness and technical performance were pivotal to the success of this demonstration.”
Rob Howard, CGO added, “Greensea IQ is proud to support the U.S. Army’s readiness initiatives, and we are proud that our team and our technology delivered when it mattered most.”
Colonel Hoagland, an Army Acquisition Officer with more than 29 years of experience, emphasized the importance of industry agility in meeting urgent military requirements. The successful execution of the demonstration reinforced the interoperability of the system across different branches of the armed forces.
