Modelling of iceberg drift motions near a large offshore structure
AbstractThe drift motions of icebergs driven by waves and currents toward a large offshore structure are examined. Results from a series of experiments with various iceberg sizes and environmental conditions are presented and compared with predictions of a corresponding numerical model. The influence of the structure on the flow field and on associated iceberg motions is shown to be significant for wave-driven drift motions when the iceberg diameter is less than approximately half the structure diameter. Agreement between the physical and numerical models is found to be reasonable, with the exception of certain cases where negative wave-drift forces act on icebergs in front of the structure.
