TEAMER: 1:4 Scale Halona Mooring Design Study Test Data and Processed Data

This report reviews the successful completion of physical model testing of the 100-Watt scale model of the novel oscillating water column type wave energy converter known as Halona. Testing was conducted on 2 different geometries, as well as testing of 2 different mooring configurations. The different geometries involved testing a single heave plate and double heave plate model. The mooring configurations consisted of a quasi-free floating soft spring mooring and a spread mooring. Regular wave and JONSWAP irregular wave testing was conducted on both geometries in both mooring configurations in the Offshore Technology Research Center wave basin.

The project objectives were:
1. to understand the impact of scale effects on the power performance and motion response of Halona for the purpose of improving the state of WEC-based AUV docking
2. to understand how the inclusion of a mooring impacts the power performance and RAOs of Halona
3. to conduct a design study on how to decrease the dry mass of Halona, while maintaining Halona's dynamic stability and power performance.
