Substructure conducts both small- and large-scale hydrographic surveys to support a wide range of applications, including navigation safety and charting, engineering planning and site characterization, environmental monitoring, habitat assessment, and marine construction project evaluation. Substructure also conducts high-resolution engineering structural assessment hydrographic surveys for evaluation of specific marine and aquatic structures, such as dock and pier facilities, bridges, and dams. We have surveyed locations along the Eastern seaboard of the United States from Maine to Florida, in the Great Lakes, and at international sites from Ireland to Peru.
Substructure owns and operates its own survey vessels, including purpose-built survey vessel Orion which is widely-recognized as an industry-leading inshore hydrographic survey platform. Substructure maintains a large inventory of SONAR, optical, and laser hydrographic data sensors, as well as the precise vessel motion and positioning systems required for accurate swath data acquisition. Substructure also owns a wide array of the specialized data acquisition, processing, and visualization software needed to process and properly present the often complex hydrographic survey datasets.
Substructure is an industrial partner with the University of New Hampshire Center for Coastal and Ocean Mapping (CCOM), a national center for expertise in ocean mapping and hydrographic sciences. Substructure has established a direct relationship with CCOM and has conducted several recent collaborative projects with various members of CCOM’s research and academic staff.
Substructure has developed a strong hydrographic survey capability that includes high-resolution multibeam and single-beam bathymetry, side-scan SONAR imaging, acoustic sub-bottom profiling, magnetic anomaly profiling, underwater video (towed and ROV) imaging, [...]
As an enhancement to standard hydrographic survey procedures, Substructure also conducts high-resolution engineering structural assessment surveys that are used to evaluate marine and aquatic structures, including dock and pier facilities, [...]
