Abstract

Inland navigation infrastructure is critical to local and global economies, and unplanned or extended down time for maintenance and repairs can have significant social and economic consequences. The extensive collection of navigation related infrastructure maintained by the US Army Corps of Engineers (USACE) is in a state of degraded performance, with some components presently being used well beyond their design life. To provide data-driven decision-support for operation, maintenance, and repair/replacement of these components, the Engineer Research and Development Center (ERDC) is developing structural health monitoring (SHM) and damage prognosis (DP) tools and techniques. ERDC has deployed the Structural Monitoring and Analysis in Real-Time of lock Gates (SMART Gate) program at several sites for long-term monitoring of hydraulic steel navigation and flood control gates. When SMART Gate systems are deployed, a significant effort and percentage of the cost is spent installing conduit to protect wires that extend from the sensors, which are typically underwater during operation, to the data logger. To reduce installation time and cost, the ERDC developed a system for energy efficient sensor data transmission underwater. The system was successfully field tested, sending data the height of the lock chamber using low nominal power, with a relatively low data loss. This paper will describe the SHM framework developed by ERDC and the development and deployment of the wireless data transmission system.
