QYSEA FIFISH Underwater ROVs Aid in Brazil Bridge Collapse Rescue

Brazil · December 2024

Disaster Scenario: Complex Underwater Search and Rescue Challenges

A catastrophic bridge collapse over the Tocantins River sent shockwaves through Brazil, resulting in multiple fatalities and missing persons. In this area, the swift current, low visibility, and turbid water make traditional diving methods both dangerous and inefficient. Search and rescue teams urgently needed a safer, more effective underwater solution.

QYSEA FIFISH ROV: A Breakthrough Approach to Rescue

To address these challenges, Brazilian responders deployed QYSEA’s FIFISH W6 and E-GO ROVs, provided by Transpetro, for a groundbreaking rescue operation.

· Ultra-clear Real-time Imaging: Even under extremely low visibility, the 4K camera and high-powered LED lights capture underwater conditions in detail, rapidly locating submerged vehicles and victims.

· Stable Performance in Strong Currents: Equipped with an advanced Q-DVL navigation system, the FIFISH W6 maintains steady positioning and hovers efficiently in fast-flowing river currents.

· Flexible Maneuverability: The compact E-GO model can slip through narrow spaces and beneath debris, extending search coverage beyond what was previously possible.

Safe, Swift, and Accurate

The FIFISH ROVs quickly demonstrated their value. Within just a few hours of deployment, the robots accurately pinpointed and helped retrieve the 13th victim, bringing critical closure to the family. At the same time, they kept dive teams out of harm’s way in a high-risk environment, delivering true “zero-risk rescue operations.”

Driving Innovation in Underwater Rescue

This rescue mission highlights the pivotal role QYSEA’s FIFISH ROVs can play in underwater infrastructure inspections and emergency operations. Their reliability, accuracy, and innovative design offer a powerful model for similar situations worldwide, instilling greater confidence in the technology’s ability to meet extreme challenges.
