Floating LNG terminal and LNG carrier interaction analysis for side-by-side offloading operation

摘要

Floating LNG terminals are a relatively new concept with the first such terminal inthe world installed this year. The hydrodynamic interaction effects between the terminaland a LNG carrier in a side-by-side offloading arrangement is investigated. The side-bysidearrangement is compared with each body floating alone to identify the interactioneffects. The hydrodynamic coefficients are obtained using the Constant Panel Methodand the analysis of body motions, mooring line tensions are done in time domain. Therelative motion between the two bodies is analyzed using WAMIT in frequency domainand WINPOST in time domain to ascertain the offloading operability of the terminalunder 1 year storm condition.
