Study of the hydrodynamic interaction of wave loads on the floating facility and the liquefied natural gas carrier during side-by-side offloading operation
Abstract
Liquefied Natural Gas Carrier (LNGC) is moored side-by-side to the Floating Liquefied Natural Gas facility (FLNG), the most eff ective and popular mooring method for obtaining the shortest way to transfer gas, and ensuring the frozen technology for liquefied gas at temperature of about -160oC. However this side-by-side offloading operation can create disadvantages for the FLNG facility and LNG carrier. This paper presents the theoretical and experimental studies of the hydrodynamic interaction of wave loads on two floating bodies with large dimension during side-by-side offloading operation. The obtained study results were applied to Bach Ho field conditions using the HydroStar Software of French Bu-reau Veritas Register, in order to compare with the case of only one fl oating facility to evaluate the increase of the wave surface elevation in the gap between the FLNG and the LNGC. Finally, the interaction between the wave and the floating facility and tanker in the side-by-side mooring which causes adverse effects for the safety of the exploitation platform was concluded.
