A tethered subsea inspection robot rated to 600 m, with a manipulator capable of fine-detail biofouling removal and an inspection sensor suite that fuses sonar, RGB, and ultrasonic thickness data.
An offshore wind operator needed routine inspection and light maintenance of subsea cable terminations and turbine foundations. Sending divers was expensive, slow, and increasingly difficult to staff. Existing ROVs handled the inspection but couldn't reliably manipulate.
Abyss-Crawler combines a stable hovering hull with a 5-DOF manipulator carrying interchangeable tooling. The perception stack fuses high-frequency sonar with stereo RGB to operate in turbid water. Operators teleoperate at high level; low-level station-keeping and contact dynamics are handled by the on-board controller in real time.
Two units have completed 280+ subsea inspection-and-clean dives across 3 offshore sites. Average dive cost is roughly 30% of the diver-equivalent operation. Critically, the system has been able to operate in sea-states that previously required postponement.
Most of our deployments start as a conversation. Tell us about the environment, and we'll tell you whether this is the right platform — or what to build instead.
