Avoiding dry dock with subsea photogrammetry

Mission’s context

In the maritime industry, ensuring the structural integrity and proper maintenance of ship hulls is critical to operational safety, efficiency, and vessel longevity. Yet, conventional inspection methods, such as dry-docking or diver-led surveys, are often time-intensive, costly, and potentially hazardous, leading to significant disruptions in vessel availability.

This case study highlights a breakthrough in hull inspection methodology through the use of subsea photogrammetry on a vessel of Oceanica’s fleet. By capturing detailed spatial data without interrupting operations, photogrammetry enables faster, safer, and more accurate assessments of a vessel’s condition. Even subtle defects or early-stage anomalies can be detected with ease, enabling proactive maintenance decisions.
