QYSEA FIFISH X1
Inquiry Form
The QYSEA FIFISH X1 is a high-performance Mission-class underwater ROV platform engineered specifically for professional non-destructive inspection (NDT), offshore energy surveys, subsea infrastructure assessment, and large-vessel inspections. Built around a powerful six-thruster vector propulsion system powered by Q-Motor Pro, the FIFISH X1 delivers exceptional current resistance and precise maneuverability, maintaining stability even in strong flow environments up to 4-knots current hold capability.
Equipped with dual 4K UHD camera sensors, high-intensity dual LED lighting, and AI-assisted navigation technologies including Dual DVL U-INS Plus fused positioning, the X1 achieves highly accurate hovering, tracking, and route planning for complex inspection workflows. Its integrated QY-MT AI Measurement Tool with built-in dual laser scalers enables millimeter-level structural measurements for crack detection, corrosion assessment, coating evaluation, and damage sizing — all without surface contact.
With an industry-leading 350-meter depth rating, 15 kg payload capacity, four stainless-steel Q-Interface power ports, and a direct power supply system supporting continuous operations, the FIFISH X1 is built for long-duration industrial deployments where reliability, endurance, and data precision are non-negotiable. It is the ideal solution for offshore oil & gas, wind energy foundations, ports and civil structures, subsea pipelines, and maritime vessel inspection programs that require professional-grade stability, scalability, and measurement accuracy.

The QYSEA FIFISH X1 is designed as a fully expandable industrial inspection platform, supporting a wide range of mission-specific payloads and precision tools for professional underwater operations.
With four powered Q-Interface ports and a 15 kg payload capacity, X1 allows operators to integrate sonar scanners, laser scalers, robotic manipulators, positioning modules, and NDT measurement tools to execute advanced inspection, detection, and survey workflows.
Whether performing subsea infrastructure assessments, vessel hull inspections, pipeline surveys, corrosion mapping, or structural measurements, the modular payload system enables rapid reconfiguration to adapt the platform to site-specific mission requirements. Combined with AI positioning, laser measurement technology, and real-time data synchronization, X1 transforms from a navigation ROV into a task-optimized underwater inspection workstation.
This flexible payload architecture empowers inspection teams to reduce dive dependency, improve survey accuracy, shorten mobilization time, and safely gather high-precision data across offshore energy, ports, civil infrastructure, and maritime asset management operations.
