Overview
This dashboard shows data from the Pioneer wave energy converter (WEC) v1 prototype’s 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 2nd, 2025 and recovered on May 1st, 2026 [9] – data from the deployment is available on MHK-DR. A Pioneer WEC v2 prototype is currently under development.
Project goals
- Deliver power to support OOI’s scientific mission

- Openly disseminate data and findings
v1 prototype goals
- WEC functionality proof-of-concept
- System management and interfaces functionality
- Benchmark numerical models for WEC performance
