Shallow Water Effects On Low-Frequency Wave Excitation of Moored Ships

摘要

This paper demonstrates how the bound wave, the spectrum ofrnthe second-order difference frequency force on an LNGrncarrier, and the moored ship’s dynamic response increase withrnincreasing period of the fundamental wave spectrum. Thernpaper demonstrates the key engineering issues and conceptsrnwith analysis results for a conventionally moored LNG carrier.rnThese issues are important because, unless they arernunderstood, ship motions and mooring loads can bernsignificantly underestimated.
