Substructure, Inc. provides nearshore and coastal underwater industrial services to commercial and government organizations. We provide ultra-high resolution hydrographic and geophysical surveys to support a variety of activities: port and harbor maintenance (dredging), pipeline and cable crossing surveys, dam face inspections, archaeological recovery and coastal engineering (beach erosion and replenishment studies). Our survey vessel Orion utilizes both multi-frequency single beam and multibeam echo sounders, side-scan sonar, magnetometers and sub-bottom profilers to generate the data required by our clients’ diverse needs.
