Wave Energy Extraction by Crescent Shaped Columns for Station Keeping of Floating Ocean Platforms - Hydraulic Model and Feasibility Study.

Abstract

Fixed or floating column-supported platforms in the ocean experience direct and reverse wave drag caused by the oscillating water particle velocity. The drag coefficient for the direct flow can be different from that for the reverse flow if the cross-sectional area of the supporting column is not symmetric about the column axis. Therefore, a net wave drag force theoretically can be produced. The purpose of this study was to determine whether this concept can be utilized to reduce the power requirements for positioning large floating platforms such as the proposed Mobile Ocean Basing System (MOBS).
