QYSEA FIFISH Underwater Drones

QYSEA underwater drones, marketed under the FIFISH series, are remotely operated ROV systems designed for inspection, survey and scientific applications. The systems operate via tether and provide live video with recording capability for documentation and analysis.

FIFISH ROV systems and operational scope

The QYSEA portfolio includes multiple FIFISH configurations, ranging from compact inspection drones to industrial platforms for professional deployment.

Depending on the model, operating depth can reach 100 m (≈330 ft) or beyond. Full 360° mobility allows stable positioning around structures and underwater assets.

Application types: inspection, search and research

FIFISH ROV systems are used for hull inspections, offshore structure surveys, quay wall assessment and pipeline documentation. Recorded footage supports reporting and technical evaluation.

They are also deployed in search operations and research projects, including marine biology, aquaculture monitoring and environmental studies.

Research and survey expansion modules

The FIFISH ecosystem supports specialised modules for advanced deployment. These include robotic grabber arms, sonar systems and positioning solutions for low-visibility conditions.

• Robotic grabber arm for intervention tasks
• Sonar module for navigation and detection

Accessories and system configuration

Available accessories include extended tethers, external power modules, lighting systems, sensor integrations and protective transport cases.

For project-based requirements, consultation with our ROV specialists can assist in defining an appropriate drone configuration and compatible accessory setup.
