Wave Transmission and Mooring Force Tests of Floating Breakwater, Oak Harbor, Washington: Hydraulic Model Investigation

摘要

Tests were conducted on a 1:1-scale model of a twin-pontoon floating breakwater, proposed for construction at Oak Harbor, Wash., to determine its effectiveness in attenuating wave action and to determine the magnitude of the mooring forces. Chain- and pile-type mooring systems were tested in conjunction with the proposed floating breakwater to determine: the effectiveness of the proposed structure in reducing the existing wave heights; the mooring forces for both the chain- and pile-type mooring systems; whether the proposed breakwater and mooring system would oscillate in resonance with the existing wave conditions; and the natural period of oscillation of the proposed breakwater, while unrestrained in still water.
