LEADING ENGINEERING SIMULATION CONFERENCE
Drillships have specific features which make ship resistance and propulsion characteristics difficult to predict with simple empirical methods. In this presentation, we will show how we applied STAR-CCM+ to optimize the hull and appendages of a drillship for speed or fuel consumption. A special hydrodynamically shaped moonpool has been developed to eliminate moonpool sloshing during transit, further reducing resistance and increasing safety on board. Furthermore, an innovative thruster arrangement was initially designed for dynamic positioning and its performance in transit was verified with the use of CFD.
The various CFD calculations and the resulting design modifications are verified and confirmed with calm water resistance and self-propulsion tests.
