Background & Challenges: Dual Pressures of Hull Corrosion and Operational Costs

In Norway's thriving fisheries industry, hull corrosion and biofouling (such as mussel growth) continuously threaten fishing vessels' performance and safety. Traditional dry-dock maintenance often leads to prolonged downtime, especially during peak fishing seasons. Such downtime not only negatively impacts earnings but also increases the already high costs associated with inspections and repairs. Fishing vessel owners urgently require a more flexible, efficient, and cost-effective solution to enable inspections and essential maintenance without removing vessels from the water.

QYSEA FIFISH ROV Underwater Hull Inspection: Rapid and Convenient Deployment, Precise Real-Time Detection Without Vessel Removal

To address these challenges, Norwegian fishing vessel operators adopted the FIFISH W6 ROV from QYSEA. Utilizing the Q-DVL system, the FIFISH W6 achieves precise underwater positioning and navigation even in murky waters. Equipped with 4K ultra-high-definition imaging and high-lumen illumination, the ROV accurately captures corrosion points, mussel growth, and other subtle hull damages. Comprehensive scans are completed without lifting vessels from the water, significantly reducing preparation and execution time for routine maintenance.

QYSEA's AI Intelligent Algorithms Dramatically Improve Inspection Efficiency, Precision, and Safety

Compared to traditional inspection methods, the FIFISH W6 conducts comprehensive hull inspections more quickly, safely, and accurately. Potential damages, biofouling on propellers, and thrusters are automatically identified and tagged in real-time. Remote operation of the ROV eliminates the risks associated with diver operations and avoids additional costs incurred by manual diving, making the maintenance process safer and more efficient.

The successful deployment of FIFISH W6 has significantly minimized downtime required for hull maintenance, ensuring uninterrupted operations during peak fishing seasons. Beyond optimizing maintenance processes, this advanced technology provides a viable approach for fisheries to manage marine corrosion and environmental pressures effectively. Maintaining a clean hull, reducing fuel consumption, and extending vessel lifespan all contribute to long-term economic benefits and sustained competitive advantage for vessel owners.

Compared to traditional diver inspections, the FIFISH W6 cuts inspection time by 60%, achieving only 40% of the original duration. It substantially enhances detection accuracy for biofouling and corrosion, effectively preventing minor issues from escalating into severe damages. Higher-resolution underwater imaging data also supplies a scientific foundation for subsequent maintenance decisions, steering the fisheries sector toward intelligent and safe operations. FIFISH W6's successful implementation in Norway demonstrates underwater robotics' immense potential to "reduce costs, improve efficiency, and enhance safety," positioning it as a critical driver of innovation and modernization in marine industries.
