Triton: Survivability Enhancement of a Multi-Mode Point Absorber

The overall goal of this project was to design and validate a survival mode for the Triton WEC that allows for a reduction in peak loads, while simultaneously allowing for a reduction of capital cost due to the elimination of overdesign to account for uncertainty. In addition, the...
