This thesis explores the idea of installing a cost-effective low-power propulsion system on a new-build FPSO and letting it transit self-propelled to its destination, without compromising the safety. To this end, a computational tool is developed capable of simulating the transit of a vessel between two points in the world. The voyage safety is addressed by implementing a suitable criterion. The developed computational tool (FPSO TRANSIM) is validated against SafeTrans, a voyage simulation program developed by the Maritime Institute of the Netherlands (MARIN). Moreover, a sensitivity analysis is performed in terms of the wind coefficients and the calm water resistance so as to determine their influence on the speed, safety and voyage duration. Further, the effect of weather routing and the application of bow thrusters are investigated while lastly simulations are performed at various power options which are coupled with a cost analysis. It is finally concluded that the minimum required power can only be determined following a thorough risk assessment.
