Greensea IQ Rapidly Supports U.S. Army With Successful Robotic Hull-Cleaning Demonstration at Pearl Harbor

Richmond, Vermont — Greensea IQ, a leader in advanced subsea robotics, autonomy, and technology solutions for defense, maritime, and commercial sectors, successfully executed a rapid-response demonstration of its EverClean robotic hull-cleaning system for the U.S. Army at Joint Base Pearl Harbor–Hickam. The event showcased how mature, commercially proven autonomy can immediately enhance maritime readiness for one of the world’s largest and most logistically complex vessel fleets.

The demonstration was initiated after Army leadership identified a critical need to reduce hull fouling, improve vessel performance, and minimize maintenance downtime. When a previously scheduled supplier withdrew unexpectedly, Greensea IQ answered the call with unprecedented speed, mobilizing technicians, equipment, and support across the country in under four days.

Colonel Rachael Hoagland, an Army Acquisition Officer with more than 29 years of experience, underscored the importance of industry agility in meeting urgent operational needs. In her summary of the event, she noted:

“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,”  Col. Rachael Hoagland.

The demonstration took place at Joint Base Pearl Harbor–Hickam, a shared U.S. Navy and U.S. Air Force installation that also supports forward-positioned Army watercraft. As one of the most strategically important maritime hubs in the world, home to the U.S. Pacific Fleet and key aviation and logistics assets, the base provides an ideal test environment for technologies that can enhance regional readiness.

Army vessel crews, Navy maintenance personnel, Army dive units, and Navy Salvage Divers all participated in the evaluation, reinforcing the interoperability and multi-service value of robotic hull-cleaning systems.

During the demonstration, Greensea IQ clearly illustrated the efficiency of using a robotic solution for hull cleaning compared to divers as it is estimated that a single operator can use a robot to clean an Army LSV hull in roughly six hours. The ability to perform fast, efficient, in-water hull cleaning offers a transformative impact on fuel consumption, vessel range, maneuverability, and maintenance scheduling.

“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,” said Rob Howard, CGO.
