Our Work

Inspection & Maintenance of Cable-Stayed Bridge Piers

For this project, BM was tasked with cleaning, inspecting, and performing vital maintenance on the piers and underwater lightning protection system (LPS) of one of the longest cable-stayed bridges.

During this mission, BM was assigned to locate and inspect the wreck of a 1,853 TEU container vessel that sank in the Red Sea following a significant maritime casualty. The vessel, detected at a depth of 300 meters using a Multi Beam Echo Sounder (MBES), was subsequently surveyed and monitored via ROV. Advanced navigation and imaging sensors were employed to capture ultra-high-resolution footage, facilitating a thorough investigation of the vessel's structural integrity and an assessment of potential pollution risks.

Shipwreck Detection, Geolocation & Inspection at the Red Sea

Support of Salvage Operation at the Port of Algiers

During this operation, BM was tasked with providing critical support for the salvage of a capsized Ro-Ro vessel at the Port of Algiers. BM mobilized a comprehensive suite of diving and underwater services assets, which played a pivotal role throughout the extended duration of the casualty response, ensuring the successful recovery of the vessel’s trim and stability.

Technical Expert Analysis of a Major Oil Spill in South Africa

BM acted in this case as a specialized technical expert for the analysis of the formation, spread, and, most importantly, the contamination caused over a large portion of the coasts of West Africa (Nigeria) by a massive oil spill resulted after a major oil leak incident offshore the Gulf of Guinea.

Scour Protection Photogrammetry Survey of Cable-Stayed Bridge Piers Footing

For this project BM was tasked with inspecting and creating detailed 3D photogrammetric models of the scour protection surrounding the four piers of one of the world's largest cable-stayed bridges, ensuring precise assessment and long-term monitoring.

Shipwreck Detection, Geolocation & Inspection at the Myrtoan Sea

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.

Lost Anchor and Chain Recovery in the North Aegean Sea

For this project, BM located and mapped a lost anchor along with its 3-shackle-long chain on a rocky seabed in the Aegean Sea. The survey was conducted using an ROV equipped with multibeam imaging sonar, UHD cameras, and USBL/DVL navigation systems. A high-resolution 3D model was then created to guide our divers during the salvage operation.

Bridge Pier Scour Protection Detailed Inspection

For this operation, BM was tasked with the detailed inspection and monitoring of the scour protection surrounding the four pier footings of the world's longest cable-stayed bridge.

Abandoned Anchor Chain Detection - Subsea Power Cable Survey

BM carried out an ROV inspection under highly challenging environmental conditions, in murky waters with extremely poor visibility to locate an abandoned chain on the seabed and evaluate possible interactions with subsea power cable infrastructure.

Maintenance of Cable-Stayed Bridge Piers

As a continuation of the 2024 inspection works for the same Client, this subsea project focused on the completion of critical maintenance works on the lightning protection and earthing systems (LPES), as well as on the concrete wall structures of the pier cones of the world’s longest cable-stayed bridge.
