Greensea IQ develops autonomous underwater robots and ocean-intelligence software for maritime, defense, and energy customers. It serves naval forces, offshore-energy operators, and hull-maintenance providers needing pier-side or at-sea autonomy. The Bayonet crawler and EverClean hull-grooming systems are field-proven over 20 years, a track record that most underwater robotics startups cannot match.
