| Résumé | This paper presents a comparison between a recently completed physical model test program, a full scale expedition and predictions using an NRC-OCRE Ice Dynamics Model (IDM), for a representative scenario of dynamic positioning of an ice management vessel. This work aims at enhancing the confidence in the numerical results, and to make it possible to extrapolate ice basin tests and field observations to a wider range of conditions. Full scale data were obtained during field trials of a dynamically positioned multi-purpose vessel, Magne Viking (MV). The collected data include thrust values, ship motion and observations of ice conditions. In parallel to the field measurements, physical model tests examined ice-vessel interactions and ship performance. In this paper, a representative trial scenario was selected from the full scale expedition for modelling in NRC-OCRE’s ice basin as well as for numerical modeling using the IDM code for predicting the ice forces on the hull. A comparison of the thruster forces and vessel movements derived from the three studies is presented in this paper. This work indicates that the numerical simulations can predict the full-scale stationkeeping scenarios with reasonable accuracy. Thus, numerical simulations may be used to examine many practical scenarios which cannot be obtained in the basin and in the field. |
