Mooring safety of parallel-connected FLNG and LNG carrier system in deep sea
2015
In this paper, coupled analysis of a parallel-connected FLNG and LNG carrier system is carried out in time domain method, taking into account of the hydrodynamic interaction between the two vessels, as well as the mechanical interaction between the vessels, moorings, hawsers and fenders. The allowable safe range of side-by-side offloading operation is derived by considering the check of two vessels' relative motions and hawsers and fenders' force condition together. Damaged and normal operating conditions are investigated for assessment of the safety in mooring, involving some major aspects, e.g., the relative motions, hawsers tension and fenders deflection during the LNG offloading process when subjected to two different loading conditions.
