Overview
This dashboard shows data from the Pioneer wave energy converter (WEC) v1 prototypeโs deployment, which provides power to a mooring within the Coastal Pioneer Array. The Coastal Pioneer Array is an NSF-funded project within the Ocean Observatories Initiative (OOI) that provides oceanographic data relevant to cross-shelf dynamics. The Pioneer WEC uses a novel pitch resonator design [1], [2] that has been optimized through modeling [3], testing [1], [4], control co-design [5], [6], [7], [8]. The Pioneer WEC v1 prototype was deployed on November 3rd, 2025 and is rescheduled to be recovered in May, 2026.
Project goals
- Deliver power to support OOIโs scientific mission
- Advance the state-of-the-art for wave energy converter design
- Openly disseminate data and findings
v1 prototype goals
- WEC functionality proof-of-concept
- System management and interfaces functionality
- Benchmark numerical models for WEC performance
- Gather data to inform future design iterations
