Computer simulations and model tests have been used to design and optimize the hydrodynamic performance of a Deep Water Drilling Vessel operating under full DP. The paper describes the procedure used to investigate the thruster-hull and thruster-thruster interaction and the automatic closed loop control system as used for the computer simulations and model tests. Results of the thruster interaction investigation will be shown. Results of the computer simulations on the DP heading capabilities in various design operating weather conditions will be presented and compared with the results of the model tests.
