AI Inertial Navigation
FIFISH X1 features the U-INS Plus fused navigation system, combining advanced hardware and software. Forward- and downward-facing Q-DVL modules deliver stable current resistance, real-time depth control, 3D route planning, and point marking, making underwater inspections smarter, more intuitive, and efficient.
AI Non-Destructive Measurement
FIFISH X1 features the AI-driven QY-MT system with proprietary vision algorithms, enabling millimeter-accurate measurement of offshore structures, subsea pipeline cracks, bridge scour, and hull coating damage. Offline data capture allows one-click none-destructive measurements, setting a global benchmark for underwater inspections.
AI Collision Avoidance
FIFISH X1 features a tri-directional collision avoidance sonar system that scans the surrounding environment in real time to prevent collisions. With customizable avoidance distance settings, it ensures enhanced operational safety when navigating complex subsea platforms and structures.
Direct Power Supply System
Uninterrupted Operation
FIFISH X1 features a direct power supply system, providing continuous 24/7 operation. By using a cable for power, it removes battery capacity limitations, offering stable and efficient support for extended deep-sea operations. This makes it ideal for long-duration, high-intensity tasks and continuous monitoring, while reducing costs related to operational interruptions and battery replacements.
