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.\n\nSections 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).", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://mhkdr.openei.org/files/639/DE-EE0008627%20D17.2%20Final%20Technical%20Report%20UD%20v4.0.pdf", "description": "Final technical report for public release", "format": "pdf", "mediaType": "application/pdf", "title": "Final Public Technical Report.pdf"}, {"@type": "dcat:Distribution", "accessURL": "https://mhkdr.openei.org/submissions/638", "description": "This is the comprehensive report scheduled for release in June, 2030.", "format": "HTML", "mediaType": "text/html", "title": "Comprehensive Final Report"}], "identifier": "https://data.openei.org/submissions/8467", "issued": "2025-06-26T06:00:00Z", "keyword": ["MHK", "Marine", "Hydrokinetic", "energy", "power", "wave energy", "deployment", "SeaRAY", "wave energy converter", "wave power system", "AOPS", "Autonomous", "Offshore Power System", "open-water testing", "autonomous power system", "renewable energy", "SCADA", "mooring system", "model validation", "deployment testing", "remote power", "non-grid", "power take-off", "system integration", "TEA", "techno-economic analysis", "risk management", "technical report"], "landingPage": "https://mhkdr.openei.org/submissions/639", "license": "https://creativecommons.org/licenses/by/4.0/", "modified": "2025-07-29T16:37:37Z", "programCode": ["019:009"], "projectLead": "Ben Goclano", "projectNumber": "EE0008627", "projectTitle": "Design, Build, and Test of Novel, Remote, and Low-Power Wave Energy Converter for Non-Grid Applications", "publisher": {"@type": "org:Organization", "name": "Columbia Power Technologies, Inc."}, "spatial": "{\"type\":\"Polygon\",\"coordinates\":[[[-157.85004931640626,21.412391660476956],[-157.74474365234374,21.412391660476956],[-157.74474365234374,21.522877598617754],[-157.85004931640626,21.522877598617754],[-157.85004931640626,21.412391660476956]]]}", "title": "SeaRAY Autonomous Offshore Power System - Final Report"}
