Designers and offshore operators frequently predict pack ice loading on offshore vessels by conducting scale model tests. One factor that can affect pack ice loading is the hull-ice friction coefficient. This research investigates the effect of hull-ice friction coefficients for a moored offshore vessel model and includes ice floe size and ice concentration as additional variables. A method of non-dimensional analysis is modified in order to deal with the multivariate nature of the new data. The resulting non-dimensional equation provides insight on relationships between the predicted pack ice force and the variables under investigation. The relationship between pack ice force and hull-ice friction coefficient is shown to be approximately a fourth root function, while the relationship for ice floe size, non-dimensionalised by the vessel beam, is approximately linear. The relationship between predicted pack ice force and ice concentration exists in a band bounded by cubic and sixth power curves. Applying the modified equation to the previous data sets shows the current analysis slightly improves the normalization of pack ice forces.
