An optical medium embedded in a hull coating emits UV light away from the surface, eliminating toxic biocides while maintaining anti-fouling effectiveness.
Teleoperated crawler removes thick biofouling via cavitation lances, containing waste to prevent invasive species spread.
A marine corrosion control system interrupts protective currents to measure electrical potentials without interference.
A C-shaped steel fender with a PVC core enables manual installation, eliminating costly radial bending equipment.
A vessel fouling risk management system calculates anti-fouling paint degradation using water temperature and speed data.
Crank and slider mechanism guides a paint gun across vertical surfaces, reducing overspray at motion endpoints through periodic oscillation.
A hull cleaning machine uses a retractable brush to contact the surface only when fouling is detected.
Binding haloaryl ions to graphite prevents oxidative degradation and maintains steady-state current densities under continuous oxidation.
A propeller with a sweep-back angle on its front edge generates propulsion force for submersible cleaning robots.
Rotating nozzle cleaning head uses magnetic positioning to secure attachment on curved surfaces.
Visible alignment grooves in transparent PVC keel guards enable air bubble detection for stronger hull bonds.
Segmented cleaning elements on a cellular plastic body generate high surface pressure via buoyancy, removing tough shells without scratching the hull.
Alternating ribs on a flexible backbone wrap around dock pilings, preventing cylindrical fenders from rolling out of place.
