Numerical Simulation of Multi-body Floating Systems in Deep Sea

摘要

A time domain analysis is carried out to investigate hydrodynamicinteractions and mechanical coupling effects in a parallel-connectedLNG-FLNG system in deep water environments. By examining therelative motions, hawser tension and fender deflection, offloadingcapabilities of side-by-side moored terminals are assessed. A CFDapproach is applied to predict the appropriate current loads, whichdemonstrates that multi-body hydrodynamic interactions have a stronginfluence on current loads. Ballast and full loaded conditions of FLNGare investigated. Results show that loading conditions have an impacton the responses of the two vessels and forces excited in hawsers andfenders appear lager in ballast condition.
