N2 - The authors regret that there are two errors in the formula and results with Riska's method in the article ‘Evaluation of selected state-of-the-art methods for ship transit simulation in various ice conditions based on full-scale measurement’, CRST 151, 2018. Corrections are as follows: Eq. (8) has to be changed to [Formula Presented] where the hi after g3 is missing in the original paper. This does not lead to an error in the result because the hi is kept correctly in the code. The second error relates to a coding error regarding Riska's formula. As the result, the curves and values with Riska's formula in Fig. 7 and Table 8 should be replaced with the ones presented here. Due to this error, some statements have to be replaced, listed as follows. In Section 5.1, the sentence ‘Riska's formula gives less deviation in predicted speed in (a), (b) and (c) compared to the others’ should be replace by ‘Riska's formula predicts more resistance and thus smaller speed in all cases compared to the others’. The text ‘Riska's formula gives the best prediction for these available data’ should be replaced by ‘Riska's formula predicts more resistance while the other two methods give very similar predictions’. In Section 6.2, the text ‘The results in Group A indicate that all three methods have certain underestimation in ship speed for the available dataset, while Riska's method may give better prediction over the other two. The deviations compared to recorded speed using Riska's formula are around 0.5 knots in most simulated cases, which are good estimations’ should be replace by ‘The results in Group A indicate that all three methods have certain underestimation in ship speed for the available dataset, while Riska's method presents slightly more deviation over the other two’. The authors would like to thank Mr. Aleksandar-Saša Milaković for spotting the errors. The authors would like to apologise for any inconvenience caused.
