A monitoring system includes a primer layer, a composite wrap, and an electrode assembly. The primer layer is configured to surround a pipe that is to be monitored. The primer layer is made of an electrically non-conductive adhesive material. The composite wrap is configured to wrap around the pipe over the primer layer. The composite wrap includes an electrically conductive nanomaterial dispersed throughout the composite wrap. The electrode assembly is coupled to the composite wrap. The electrode assembly and the electrically conductive nanomaterial are configured to monitor degradation of the composite wrap.

A system and method for delivering volatile corrosion inhibitor (VCI) for protecting against external corrosion to the bottom, soil-side, surface of a storage tank is disclosed. The VCI delivery system can include a transport material buried underneath the tank and a carrier structure for containing the transport material. VCI can be supplied to the transport material from an external VCI storage tank and the supply regulated by a control valve. The transport material is configured to adaptively and controllably release VCI into the soil in response an external stimulus. The transport material can passively adjust the VCI release rate as a function of a stimulus including pH or soil potential. Additionally, a control system can monitor soil conditions and generate the stimulus that triggers the release of the VCI. Also disclosed are systems and methods for deploying the VCI delivery system under the tank using horizontal drilling techniques.

Example devices, systems, and methods for structural health monitoring of composite structures are disclosed. One example method includes attaching a device to an object by fitting the device around the object, where the device includes an enhanced magnetorheological elastomer (MRE) and an elastomer, the enhanced MRE has a folded pattern, the enhanced MRE is embedded in the elastomer, and the device is configured to output a voltage signal generated by the enhanced MRE based on a strain induced on the device in response to deformation. A digital signal is generated based on the voltage signal and using a data processing system, where the data processing system includes a Wheatstone bridge, an amplifier, and an analog-to-digital convertor. A strain value associated with the object is determined based on the digital signal.
