The use of Stabilizers in FPSO (floating production, storage, and offloading) systems with a turret is investigated under the light of a reviewed, perhaps new, stability analysis specifically for the turret and an order of magnitude analytical approach. This has been made together with model testing results and time-domain nonlinear simulations. It is shown by these various and independent methodologies that stabilizers, never considered so far for applications on FPSOs, are naturally feasible, opening the field for novel designs.
