SeaRAY Autonomous Offshore Power System - Final Report
This report documents the full lifecycle of the SeaRAY Autonomous Offshore Power System (AOPS) project, detailing the design, development, testing, deployment, and recovery of a novel low-power wave energy system intended for remote, non-grid applications. The report includes technical specifications and design evolution of the system components, such as the hull, power take-off (PTO), electric plant, supervisory control and data acquisition (SCADA) system, mooring, and the seafloor base unit. It also provides risk management plans, fabrication and assembly procedures, and test plans conducted both in the lab and at dockside.
Sections cover system integration, permitting considerations, and in-harbor operational testing, followed by a detailed account of at-sea deployment, performance monitoring, and recovery operations. Observations related to system power output, mechanical stability, component failures, and deviations from design expectations are presented with supporting data. The report concludes with model validation results, a discussion of techno-economic metrics, lessons learned, and implications for future development. This report is a preliminary release containing a subset of the full project documentation. A comprehensive version, including additional technical detail and supporting data, is scheduled for public release in 2030 (link below).
