Marine hydrokinetic (MHK) projects are composed of undersea power generating equipment that converts energy of waves, tides, or ocean currents into electricity. Of primary interest when deploying MHK devices is gaining an understanding of potential harmful interactions between marine animals and equipment at proposed development sites. Therefore, a high priority regulatory expectation exists to observe...
Environmental monitoring is a critical aspect of marine renewable energy project success. A new system called Unobtrusive Multistatic Serial LiDAR Imager (UMSLI) has been prepared to capture and classify marine life interaction with electrical generation equipment. We present both hardware and software innovations of the UMSLI system. Underwater marine animal imagery has been captured for the first...
We describe a wireless link management framework for an ocean platform-to-shore communication system that uses time series forecasting to predict the available link capacity using ocean platform sensor data metrics to boost link robustness and to efficiently manage quality of service. Based on the predicted link capacity the OCTT Wireless Link (OWL) manager coordinates transmission scheduling of XML/HTTP...
The System Hazard Indication and Extraction Learning Diagnosis (SHIELD) methodology was developed as a novel method to perform system hazard analysis and resilient design. In an earlier paper we described SHIELD conceptually and outlined the details necessary to conduct the analysis manually. This approach integrates state space examination into the analysis process in order to facilitate efficient...
Ocean currents offer a green, renewable, and sustainable energy resource which can provide grid-scale power and acceptable capacity factors. Technology to harness these currents is still immature and not well understood. Of major concern are the construction, reliability, and performance of rotors fitted to turbines. The efforts of the collaborative partnership described in this paper are focused...
In this paper we introduce a new methodology that integrates system resilience engineering and hazard analysis into complex system design. We then demonstrate its performance by applying it to the design of a Prognosis and Health Monitoring (PHM) system for an ocean current power generator. Three common methodologies for system hazard analysis were tested by applying them to the PHM system's network...
