ROV

FIFISH X1

350 m mission ROV with dual Q-DVL, a 15 kg payload and direct surface power.

X1 uses six vector-arranged thrusters, forward and downward DVL, and U-INS Plus for demanding inspections. Four power/data ports and modular skids support NDT equipment, manipulators and sonar. A dual-camera system and Q-iRC console combine imagery, sensor data and mission views. The model-specific datasheet specifies 350 m; the broader X-series customization claim is not a standard X1 depth rating.

Configuration options

Direct-power X1Power and deployment

350 m vehicle and tether with surface power unit, underwater converter and Q-iRC console.

NDT and tool skidsMission configuration

QYSEA lists ultrasonic thickness measurement, cathodic protection, multi-parameter sensing and a water-jet cleaner. Tool specifications and integration are configured per mission.

Compatibility and naming

Tool ratings do not increase the vehicle depth rating. Select the connector, mounting kit and hardware revision for this ROV; optional equipment is configured separately.

Performance notes

Endurance, current holding and charging figures depend on the task, payload, water conditions and temperature. Tether length and rated diving depth are different limits; the complete configured system must suit the mission.

Accessories & payload options

Options are selected for your application. Included equipment, interfaces and compatibility are confirmed in your quotation.

Imaging and inspection

  • 2D Image Sonar

    Named in QYSEA’s current accessory selector. Exact interface and configuration follow the selected host.

Control and communications

  • Q-iRC | Industrial Remote Controller

    Named in QYSEA’s current accessory selector. Exact interface and configuration follow the selected host. Store hardware revisions must be confirmed against the vehicle serial number.

Measurement and navigation
