Seamless & Efficient
FIFISH can be easily carried and deployed via fast boats seamlessly, with setup completed in 3-5 minutes. Just 2-3 people can quickly deploy it from small vessels or offshore wind platforms, enabling rapid underwater inspections and enhancing emergency response efficiency, offering users convenient and efficient operational support.
Fully Stable Operation
The powerful 4-knot speeds of the FIFISH AI ROV, combined with the self-developed Q-DVL system, enables automatic flow resistance and hovering in challenging turbulent waters. With multiple NDT tools and other attachments, it self-adjusts its body posture to maintain stability and balance, ensuring safe and efficient operation in high-flow environments.
Advanced Visual System
FIFISH AI ROVs seamlessly integrate advanced hardware and software to meet the comprehensive underwater observation needs of offshore wind farms. Its Dual 4K cameras and 12,000 lumen offer real-time monitoring of both the underwater environment and equipment status. AI filtering algorithms effectively remove suspended particles, ensuring clear visuals for inspections. Additionally, AI diver tracking ensures real-time dynamic tracking and video transmission, safeguarding diver operations.
1+N: Non-Destructive Testing
FIFISH ROVs carry multiple non-destructive testing tools, providing a comprehensive solution for offshore wind energy. This includes fast payload replacement in minutes, surface cleaning, NDT, anomaly detection, and data report generation. FIFISH can accurately detects pile thickness loss, corrosion protection, and key water quality parameters in real time, reducing testing costs and operational risks.
AI-assisted Efficiency
FIFISH AI ROV integrates advanced AI systems to enhance efficiency and safety in offshore wind energy.
It features Intertial navigation (U-INS) for precise positioning, autonomous navigation, and rapid large-area inspections.
QY-MT (measurement tool) provides accurate data on underwater structures' dimensions, cracks, and corrosion for damage assessment. QY-BT (bathymetric mapping) generates cost-effective seabed topography and depth data, supporting foundation scour monitoring, jacket installation, and cable laying with precise terrain information.
24/7 Continuous Operation
Equipped with a direct power supply system, the FIFISH AI ROV enables 24-hour, 7-day continuous operation. This eliminates battery capacity limitations, ensuring long-term, stable underwater robot performance. It is ideal for high-intensity, extended-duration tasks at offshore wind farm foundation piles, substations, and other platforms, significantly reducing downtime and battery replacement time costs.
