SHR3DR - Sub-seafloor High Resolution 3D Reconstruction

FTL’s SHR3DR (Sub-seafloor High Resolution 3D Reconstruction) is a specialized geophone-based sensor and processing system that simplifies the evaluation of salt-saturated sediments and other structural configurations typical of waterfront facilities, achieving 80 feet of penetration below the mudline in water depths to 90 feet. It applies AI/ML analysis of seismograph data, to assist in determining morphology, location, and dimension of subterranean voids and structures for Port Damage Repair (PDR) operations, including Port/Harbor/Shipyard assessment, performed by several Navy organizations (NECC, UCT, NMCB). SHR3DR enables the inspection of waterfront facilities ( including piers, wharfs, relieving-platforms, other shipyard structures) for voids (structural and soil), structures (piles, pile-caps, beams, deck), and stability (load capacity, limits). Working closely with established manufacturers of seismic surveying equipment, SHR3DR will be a Government-off-the-shelf (GOTS) and commercial product that enables nondestructive investigation (classification, quantification, location, dimension) of sub-seafloor structures, voids, and construction patterns. It leverages FTL’s 2D and 3D computer vision and machine learning pipeline developed for automated inspection of Navy piers. It combines cutting-edge seismic imaging hardware with mature geotechnical investigation approaches to provide unique 3D awareness around and below shoreline facilities.
