Eigenvalue analysis on floating LNG bunkering terminal side-by-side moored with LNG carrier and two LNG bunkering shuttles

Abstract

Floating LNG Bunkering Terminal(FLBT) is a newly emerging offshore platform which can be regarded as a LNG station at sea. It has its own station-keeping system, while it is additionally moored with other vessels during LNG loading or unloading processes. The ship-to-ship mooring system is composed with a number of mooring ropes and fenders, which might trigger unexpected motions. In this study, eigenvalue analysis was conducted, which gives the resonant frequencies and modes of vessels induced by the ship-to-ship mooring system. These eigenvalues were drawn in the model test results. Finally, we figured out some notable characteristics induced by ship-to-ship mooring system. ？ 2019 by the International Society of Offshore and Polar Engineers (ISOPE).
