Abstract/Summary Problems relating to weathervaning have been reported due to yaw instability in various Floating, Production, Storage and Offloading (FPSO) systems operating around the world thus disrupting the production/deck operations. Hydrodynamic analyses are economical means of analysing the dynamics of a turret based system when subjected to different sea states. The numerical results are verified by model tests to establish reliability of the results. A parametric study of the turret-moored FPSO is conducted using the AQWA suite of hydrodynamic software to evaluate the effect of the same in yaw instability. The parameters studied include Turret position and hull length. The numerical results are compared to model tests. The FPSO was observed to weathervane and reach equilibrium at an angle to the incident waves. This paper assesses the effect of these parameters and compares the same with the model test results.
