NTH  recently performed an underwater inspection of existing shoreline elements with our submersible remotely operated vehicle (ROV) at the Straits State Harbor.  Traditionally, inspections of these types of underwater structures are completed by divers. Using our cutting edge underwater drone technology, NTH performed the underwater inspections, safely, efficiently, and cost-effectively. This presentation will provide a brief history of the Straits State Harbor pier and discuss the innovative submersible ROV methods NTH used in the condition assessment.
