Scour Protection Photogrammetric Inspection of Cable-Stayed Bridges Piers

After a geneal cargo vessel sank in the Myrtoan Sea, BM was tasked with locating the wreck and capturing footage for determining whether it posed an environmental risk.

To begin, an MBES (Multi-Beam Echo Sounder) survey was conducted to detect the wreck and analyze its position, orientation, and structural integrity. This initial data was crucial in planning the ROV mission, ensuring an efficient and targeted inspection. The wreck was located at a depth of 200 meters, and due to the possibility of structural instability and pollutant leakage, a detailed visual assessment was deemed necessary.

With the precise location confirmed, BM’s ROV—equipped with a USBL positioning system—was deployed for an in-depth inspection. Despite the challenges of deep-sea operations, the wreck was thoroughly examined to assess any immediate or long-term hazards. UHD videos, high-resolution photographs, and positional data were collected, providing the client with a comprehensive visual and analytical report. This data enabled them to perform a well-informed risk assessment and plan any necessary mitigation efforts.
