Abstract: A mathematical model for motion of moored platform interacting with drifting ice feature was developed using equations of spatial motion of solid body (Euler equations). Besides ice loads acting on the platform other factors of external action that are determining platform's behaviour were considered, such as: hydrostatic and hydrodynamic forces and moments, tightening forces in the mooring lines and inertial loads. The elaborated model was applied to reconstruction ice loads acting onto the moored platform model from drifting ice feature using measured values of tightening forces in the mooring lines and kinematic and dynamic parameters of the platform motion. The model tests were carried out in the Ice Tank at the KSRI. The influence of spatial motion of the moored platform on values of ice load components was considered in the paper. It was shown that the mathematical model might be used for assessment of ice loads on moored platforms both in model and field tests.
