July 2024 marked an exciting milestone for Voyis as we partnered with MarineNav Ltd. to integrate our Discovery Stereo Vision System with the MarineNav Oceanus Ultimate ROV. This collaboration, completed in Ontario, Canada, culminated in a successful hull inspection demonstration that showcases the robust capabilities of this integrated solution. Today, we’re thrilled to share the next phase of our exploration, focusing on the critical importance of data quality control and coverage assurance during hull inspections, and how Voyis VSLAM Powered by EIVA NaviSuite is revolutionizing these operations. 

 The Importance of Data Quality in Hull Inspections 

Ensuring the structural integrity of a vessel’s hull is paramount to its operational efficiency and longevity. Over time, hulls are exposed to harsh marine environments that contribute to issues such as corrosion, fouling, and structural damage. Regular inspections are necessary to detect and address these concerns before they escalate into costly repairs or operational downtime. However, the effectiveness of these inspections is entirely dependent on the quality and completeness of the collected data. 

Traditional inspection methods, often reliant on divers or basic sonar imaging, may result in incomplete coverage or inconsistent data quality. The integration of advanced ROV technology and optical sensors has transformed hull inspections, offering a more comprehensive, efficient, and repeatable approach. Yet, to fully leverage these advancements, it is critical to ensure that all necessary data is collected accurately and comprehensively to support high-fidelity photogrammetry models. 

 The Power of Voyis VSLAM Powered by EIVA NaviSuite for Hull Inspections 

The integration of Voyis VSLAM Powered by EIVA NaviSuite with the Discovery Stereo and MarineNav Oceanus Ultimate ROV provides a groundbreaking solution for hull inspections. This innovative VSLAM (Visual Simultaneous Localization and Mapping) solution ensures precise localization of the ROV during inspections, enabling comprehensive coverage and superior data quality control. 

By utilizing our VSLAM solution, the inspection team gains real-time spatial awareness, allowing for optimized survey paths and thorough coverage verification. This eliminates the risk of data gaps that could compromise the integrity of the final inspection report. The system’s ability to track the ROV’s position relative to the hull structure ensures that every section is meticulously scanned, facilitating the creation of a complete, high-resolution 3D photogrammetry model during post-processing. 

 Enhancing Post-Processing with Accurate Data Acquisition 

One of the most significant challenges in hull inspections is ensuring that the collected data is sufficient for generating detailed models without requiring costly and time-consuming repeat missions. With Voyis VSLAM Powered by EIVA NaviSuite, inspectors can confidently achieve complete coverage on the first attempt, reducing operational costs and improving efficiency. The solution provides immediate feedback on data coverage, allowing for adjustments in real time and ensuring that every critical area is captured with the highest level of detail. 

Additionally, the integration of high-resolution imagery from the Discovery Stereo Camera further enhances the post-processing phase when creating a photogrammetric model. This combination allows for accurate defect identification, precise measurements, and long-term monitoring of the vessel’s hull condition with unmatched clarity and consistency. 

The successful implementation of Voyis VSLAM Powered by EIVA NaviSuite in hull inspections marks a significant step forward in ensuring data reliability and operational efficiency. This advanced solution empowers vessel operators with the confidence that their hull inspections are thorough, accurate, and repeatable, ultimately supporting proactive maintenance and asset longevity.
