Preliminary Study on Characteristics of Motions of Side-by-side Moored Vessels during Waves in Port

Abstract

Recently FSRU (Floating storage and regasification unit) system has been applied to not only offshore region but also ports and harbors region. The motions and mooring loads of a ship moored along jetty and side-by-side moored two ships are influenced by wave conditions such as wave height, period and its direction, and shallow water effect. In this study, we have conducted several physical model tests on ship behaviors for a single moored ship (Ship-to-jetty: STJ) and side-by-side two vessels where one ship is moored along dolphins (STJ+STS: Ship-to-ship: STS) during waves to obtain the property of ship motions and mooring loads. Also a numerical simulation system has been developed for the side-by-side moored two vessels to investigate the property of ship motions and mooring loads.
