Relative Motions of FLNG and LNG Carriers Arranged Side by Side and an Assessment of Their Operation

Offloading operability is a critical issue in floating liquefied natural gas (FLNG). In the offloading process, because loading arms have track records in liquefied natural gas (LNG) terminals in ports, they will be used between FLNG and an LNG carrier arranged side by side. However, the environmental conditions of operation sites are harsher than those of ports. This paper presents the results of an offloading operability assessment. First, the ship motions and the wave elevations between the two vessels were obtained by model tests and numerical calculations. The operable conditions were investigated based on the relative motions and the criteria. Finally, the offloading operability was evaluated.
