Innovative Inspection of Fukushima’s Underwater Infrastructure: FIFISH V6 PLUS Sets a New Benchmark

Fukushima, Japan · June 2023

Key Challenges: Limitations of Traditional Methods

Infrastructure inspections in Fukushima require strict precision, particularly for monitoring sediment distribution, water flow conditions, and structural integrity. Traditional inspection methods rely on divers or heavy, complex equipment, which come with high costs and significant safety risks—especially in deep water or confined spaces. A safer, more efficient, and highly accurate solution was needed to overcome these challenges.

Solution: FIFISH V6 PLUS and Its Breakthrough Capabilities

To meet the rigorous inspection requirements, the Fukushima team deployed the FIFISH V6 PLUS ROV, significantly improving efficiency and safety:

· High-Precision Real-Time Monitoring: Equipped with advanced sensors, the ROV provides real-time, accurate data on water depth, temperature, and sediment distribution.

· Exceptional Maneuverability: With 360° omnidirectional movement, it operates stably in complex structures and depths exceeding 100 meters.

· Ultra-HD Visual System: A 4K high-definition camera and powerful LED lighting ensure clear imaging in low-light conditions, enabling precise identification of cracks, corrosion, and sediment buildup.

Performance That Exceeded Expectations

Outstanding Results: Enhanced Accuracy, Efficiency, and Safety

The FIFISH V6 PLUS delivered exceptional performance in real-world operations, achieving the following results:

· Twice the Efficiency: Inspection time was reduced by over 50%, minimizing operational downtime and ensuring the continuous stability of the facility.

· Accurate Insights: Real-time data collection and analysis of depth, temperature, and sediment distribution allowed for rapid identification of risk areas and structural wear, ensuring targeted maintenance actions.

· Zero-Risk Operations: The remote-controlled system fully replaced diver-based inspections, significantly reducing human safety risks.

Setting a New Standard for Underwater Inspections

The introduction of the FIFISH V6 PLUS has revolutionized the efficiency, precision, and safety of underwater infrastructure inspections in Fukushima. This success story sets a benchmark for similar global applications, highlighting the indispensable role of advanced technology in underwater inspections and providing a robust technical foundation for future water infrastructure operations and maintenance.
