One of the areas where 3D photogrammetry has proven to be particularly useful is in the inspection of submarine outlets of safety spillways.
These structures are critical for the safe and efficient functioning of pipelines, but they are often located in hard-to-reach locations and subject to the corrosive effects of saltwater and waves.
To address these challenges, the R&D department of the company Vectrino d.o.o. developed a special “rig” that enables the use of four high-resolution cameras on a remotely operated submarine (ROV).
This rig was designed and tested to ensure that the artificial lighting used during the filming of the underwater outlet does not interfere with the 3D modeling process.
ROV Outfall Photogrammetry: The Quality of Data Output
The cameras are strategically placed around the ROV, allowing for the creation of a 3D model of the damage from multiple angles.
This enables a more accurate and detailed inspection of the condition of the recorded objects, reducing the risk of any details being missed.
After completing the recordings in the field, the collected data is analyzed, and a report with necessary information about the pipeline and its condition is created.
The report includes a detailed 3D model of the submarine discharge, categorizing and presenting all damage found.
This technology enables clients to inspect all surfaces and plan future steps from the comfort of their office, thanks to the creation of a “digital twin.”
This is especially important for managing assets that are difficult to monitor or access, as it allows clients to obtain excellent quality images at depths of up to 300 meters and easily detect damaged areas.
In summary, 3D photogrammetry has proven to be a game-changer for subsea infrastructure inspection.
It greatly improves the quality of data output, enabling more accurate and detailed inspections of objects at any time.
This technology enables property management specialists to work more efficiently, ensuring the safety and efficient functioning of critical infrastructure.
