With conventional sources of uranium forecasted to be depleted within a century, developing methods to cost-effectively harvest uranium from seawater, which is estimated to contain 1,000 times more uranium than land does, is crucial to the continued viability of nuclear power generation. Studies have shown that coupling a uranium harvester system with an existing offshore structure, such as a floating wind turbine (FWT), could greatly reduce the cost of harvesting uranium from seawater as it eliminates the need for dedicated moorings and increases the overall energy-gathering ability of the offshore wind farm. This paper explores the hydrodynamic effects of adding a uranium harvester to an offshore FWT. The experimentally determined hydrodynamic responses of two designs of a symbiotic machine for ocean uranium extraction (SMORE) are compared with that of an unmodified FWT. Both SMORE designs utilize adsorbent filament that is enclosed in a hard permeable shell to decouple the mechanical and chemical requirements of the device. It was found that neither SMORE design significantly shifted the resonant peaks of the FWT.
