Fast navigation | Deep dive | High efficiency

The ROV FIFISH SAR VERSION is a professional-grade ROV platform equipped with a powerful patented Q-motor system that provides fast dive speeds, power consumption and precise controls for your underwater missions and operations. It is equipped with a dual camera system, a dive depth of 350 meters and a wide range of additional capabilities, providing greater reliability and possibilities for search and rescue missions.

350m – Maximum depth of immersion

3 nodes – Current resistance

-10~40°c – Operating temperature range

4-6 hours – Maximum operating time (depending on the type of work and conditions)

Sonar imaging system

2D and 3D imaging sonar equipment can be integrated into the ROV FIFISH SAR VERSION, providing the operator with the ability to traverse, scan and inspect subsea environments in dark and turbid conditions. Obtain detailed visual data of the surrounding seabed and operate in the oceans with greater stability and efficiency.

Station locking system

FIFISH SAR VERSION’s ROV Station Lock algorithm is an adaptive and intuitive system that locks the ROV’s position underwater and accurately returns it to its locked position against any interference from underwater environments. Performs and inspections with exceptional stability, smoothness and precision.

Robotic arm

O ROV FIFISH SAR VERSION pode ser equipado com vários tipos de garras, se adaptando perfeitamente a diferentes tipos de ambientes e requisitos operacionais.

Side scan sonar system

The ROV’s integrated side-scan sonar creates effective images of large areas of the surrounding seafloor, as well as navigating and identifying targets in low-visibility, dark and murky underwater environments. Thanks to image equalization technology, it scans underwater objects with optimal clarity and contrast, essential for emergency and recovery tasks.

Powerful and precise, compact and stable

By eliminating the various risks of traditional diving methods, the ROV FIFISH SAR VERSION reduces the challenges and complexities of underwater research and recovery tasks. With support for several additional inspection-based tools, the ROV effectively addresses challenges in different scenarios.

Dual 4K camera system

The FIFISH SAR VERSION ROV’s dual 4K camera system offers an ultra-wide field of view, facilitating greater efficiency in inspection tasks, as well as providing operators with a complete picture of the surrounding underwater environments. The camera system allows for thorough inspections as well as the collection of a wide variety of data through the FIFISH software, which is beneficial for organizations and professional teams.

Underwater Quick Positioning System (U-QPS)

U-QPS is a software and hardware ecosystem that provides a 3D map of the real-time location of the ROV FIFISH, POI logs, three-dimensional dive trajectories, as well as a one-click function to return to its original location. Software applications designed by QYSEA provide the ROV pilot with an enhanced operating and inspection experience.

Onshore Power Supply System (OPSS)

Experience an additional increase in run time with the Shore Power system, which provides simultaneous running and charging for longer lasting dive sessions. QYSEA’s patented watertight charging systems are safe, reliable, protected, leak-proof, shock-proof and offer excellent quality for worry-free operation.
